Description

Display and control method thereof

The present invention relates to a display technology, and in particular to a display and a control method thereof.

Some monitors on the market offer a rotation function, allowing users to manually adjust to portrait or landscape display as needed. However, these monitors simply switch the screen according to the screen's posture without providing additional guidance.

The present invention provides a display and a control method thereof, which can provide appropriate guidance instructions as the display rotates, thereby improving the user experience.

The control method of the display of the embodiment of the present invention is applicable to a display including a bracket, a screen, a rotating mechanism, a sensor and a controller. The rotating mechanism is arranged on the bracket, the rotating mechanism is connected to the screen, and the sensor is arranged on the screen. The control method includes (but is not limited to) the following steps: determining the angle of the screen relative to the reference direction according to the sensing value of the sensor through the controller, and displaying a corresponding prompt image on the screen according to the angle through the controller. The sensing value corresponds to the posture of the screen. The prompt image is used to guide the rotation of the screen.

The display of the embodiment of the present invention includes a bracket, a screen, a rotating mechanism, a sensor and a controller. The rotating mechanism is arranged on the bracket and is connected to the screen. The sensor is arranged on the screen. The controller is coupled to the screen and the sensor. The controller is configured to determine the angle of the screen relative to the reference direction according to the sensing value of the sensor, and display a corresponding prompt image on the screen according to the angle. The sensing value corresponds to the posture of the screen. The prompt image is used to guide the rotation of the screen.

Based on the above, according to the display and control method thereof of the embodiment of the present invention, corresponding guidance prompts can be displayed according to the posture of the screen, thereby effectively guiding the user's operation and improving the user experience.

In order to make the above features and advantages of the present invention more clearly understood, embodiments are specifically cited below and described in detail with reference to the accompanying drawings.

1A and 1B are schematic diagrams of a display 10 according to an embodiment of the present invention. Referring to 1A and 1B, the display 10 includes (but is not limited to) a bracket 11, a screen 12, a rotating mechanism 13, a sensor 14, a speaker 15 and a controller 16.

The bracket 11 is used to support the body of the display 10 .

Screen 12 can be LCD, LED screen or OLED screen. In one embodiment, screen 12 is used to display images.

The rotating mechanism 13 is disposed on the support 11 and is connected to the screen 12 so that the screen 12 can rotate relative to the support 11. The screen 12 can be rotated by manpower or a motor (which can be disposed on the rotating mechanism 13).

For example, FIGS. 2A to 2C are schematic diagrams illustrating multiple postures according to an embodiment of the present invention. Referring to FIG. 2A , the screen 12 is in a landscape mode, and the angle θ1 of the direction D1 of the screen 12 (hereinafter, the direction corresponding to its long axis is taken as a representative direction) relative to the reference direction RD (e.g., downward) is 90 degrees. Referring to FIG. 2B , the screen 12 is rotated relative to the bracket, and the angle θ2 of the direction D2 of the screen 12 relative to the reference direction RD is approximately 45 degrees. Referring to FIG. 2C , the screen 12 is in an upright mode, and the angle θ3 of the direction D3 of the screen 12 relative to the reference direction RD is approximately 0 degrees.

The sensor 14 is disposed on the screen 12. The sensor 14 may be an accelerometer, a gyroscope, a geomagnetic sensor, an inertia sensor or other posture sensors. In one embodiment, the sensing value/data of the sensor 14 is used to determine the posture of the screen 12.

The speaker 15 is disposed on the screen 12. In one embodiment, the speaker 15 is used to play sound.

The controller 16 is coupled to the screen 12, the sensor 14 and the speaker 15. The controller 16 may be a central processing unit (CPU), a microprocessor, a digital signal processor (DSP), a programmable controller, a field programmable gate array (FPGA), an application-specific integrated circuit (ASIC), or other similar components or a combination of the above components.

In one embodiment, the controller 16 is disposed in the display 10. In another embodiment, the controller 16 is disposed in a computer device, and the computer device is wired or wirelessly connected to the display 10. The computer device can be a desktop computer, a laptop computer, a smart phone, a tablet computer, an intelligent assistant device, a wearable device, a smart home appliance, a server, or other electronic devices.

Hereinafter, the method described in the embodiment of the present invention will be described in conjunction with various devices and components in the display 10. Each process of the method can be adjusted according to the implementation situation, but is not limited thereto.

FIG3 is a flow chart of a control method for a display according to an embodiment of the present invention. Referring to FIG3 , the controller 16 determines the angle of the screen 12 relative to the reference direction according to the sensing value of the sensor 14 (step S310). Specifically, depending on the type of the sensor 14, its sensing value may be acceleration, angular velocity, geomagnetism and/or angle. The angle of the screen 12 relative to the reference direction is a measurement indicator representing the posture of the screen 12. In other words, the sensing value of the sensor 14 corresponds to the posture of the screen 12. Taking FIG2A to FIG2C as an example, the reference direction RD is downward, and the angles of the screen 12 are θ1, θ2 and θ3 respectively and correspond to different postures. It should be noted that the reference direction RD is not limited to downward.

The controller 16 displays a corresponding prompt image on the screen 12 according to the angle (step S320). Specifically, the prompt image is used to guide the rotation of the screen 12. The prompt image can guide the user to perform the rotation operation on the screen 12.

FIG. 4 is a flow chart illustrating display control corresponding to different angles according to an embodiment of the present invention. Referring to FIG. 4 , the prompt image includes a first image, a second image, and a third image. Different images correspond to different (angle) intervals. For example, FIG. 5 is a schematic diagram illustrating angles and intervals according to an embodiment of the present invention. Referring to FIG. 5 , it is assumed that 0 to 90 degrees can be divided into three intervals Z1, Z2, and Z3 according to breakpoints T1 and T2. Assume that the initial direction ID of the screen 12 is defined as 0 degrees (for example, the right or bottom of the figure), the breakpoint T1 is 40 degrees, and the breakpoint T2 is 50 degrees. 0 to 40 degrees is interval Z1, 40 to 50 degrees is interval Z3, and 50 to 90 degrees is interval Z2. That is, the three intervals are not the same. However, the range of each interval Z1~Z3 can still be adjusted as needed.

When the angle is in the first interval (such as interval Z1 in FIG. 5 ), the controller 16 displays the first image on the screen 12 (step S410). When the angle is in the second interval (such as interval Z2 in FIG. 5 ), the controller 16 displays the second image on the screen 12 (step S420). When the angle is in the third interval (such as interval Z3 in FIG. 5 ), the controller 16 displays the third image on the screen 12 (step S430). Since these three images correspond to different (angle) intervals, the contents of these three images can indicate the posture of the screen 12.

6A to 6E are schematic diagrams illustrating visual guidance in different postures according to an embodiment of the present invention. Referring to FIG. 6A , the image content of the screen 12 includes an image area IA1 . The image area IA1 may occupy the entire display area of the screen 12 , but is not limited thereto. The image area IA1 of the screen 12 may display a user interface, a window, a video or a picture.

In one embodiment, when the angle is in a first interval (e.g., interval Z1 in FIG. 5 ), the first image includes an image area that reduces the content of the previous image as the angle changes relative to the initial angle. The first image corresponds to, for example, area Z1 in FIG. 5 , and is relatively close to the initial direction ID. The initial direction ID may be right/left corresponding to the landscape mode, or may be bottom/top corresponding to the portrait mode. The initial angle is the angle between the initial direction ID and the reference direction RD.

For example, please refer to Figures 6A and 6B, assuming that the initial direction ID (corresponding to the long axis of the screen 12) and the reference direction RD are both to the right. That is, the initial angle θI is 0 degrees. As the screen 12 rotates clockwise, from the (representative) direction D1 of the screen 12 (as shown in Figure 6A) to the (representative) direction D2 (as shown in Figure 6B), the angle θ2 relative to the reference direction RD gradually increases, so that the change in this angle θ2 and the initial angle θI increases. The image area IA2 shown in Figure 6B is smaller than the image area IA1 shown in Figure 6A. At the time point of Figure 6B, the screen 12 can maintain the display of the previous image content displayed by the image area IA1 of Figure 6A, but the image area is reduced. In addition, the image area IA2 of the previous image content does not exceed the display screen boundary IE1 of the screen 12. For example, the vertex A1 of the image area IA2 is located on the screen boundary IE1 (the corresponding vertex may also be located on another screen boundary). In addition, the angle θ2 gradually increases, and in order to prevent the image area IA2 from exceeding the display screen boundary IE1, the image area IA2 will be gradually reduced.

For another example, please refer to Figures 6C and 6D. Assume that the initial direction ID is downward (corresponding to the long axis of the screen 12) and the reference direction RD is to the right. That is, the initial angle θI is 90 degrees. As the screen 12 rotates counterclockwise, from the (representative) direction D3 of the screen 12 (as shown in Figure 6C) to the (representative) direction D4 (as shown in Figure 6D), the angle θ4 relative to the reference direction RD gradually decreases, so that the change in this angle θ4 and the initial angle θI increases. The image area IA4 shown in Figure 6D is smaller than the image area IA3 shown in Figure 6C. At the time point of Figure 6D, the screen 12 can continue to display the previous image content displayed by the image area IA3 of Figure 6C, but the image area is reduced. In addition, the image area IA4 of the previous image content does not exceed the display screen boundary IE2 of the screen 12. For example, the vertex A2 of the image area IA4 is located on the screen boundary IE2 (the corresponding vertex may also be located on another screen boundary). In addition, when the image area IA4 does not exceed the display screen boundary IE2, as the angle θ4 decreases, the image area IA4 will gradually decrease.

In one embodiment, the image area of the previous image content displayed on the screen 12 gradually changes to a specified color (e.g., white or gray) as the angle changes relative to the initial angle. In other words, at the beginning, the screen 12 displays the previous image content. As the change continues to increase, the display area gradually changes to a color block of the specified color to highlight the shape of the display area, allowing the user to perceive the visual change.

In one embodiment, when the angle is in a first interval (eg, interval Z1 of FIG. 5 ), the first image includes an image region that magnifies the content of the previous image as the amount of change of the angle relative to the initial angle decreases.

For example, referring to FIG. 6A and FIG. 6B , as the screen 12 rotates counterclockwise from the (representative) direction D2 (as shown in FIG. 6B ) of the screen 12 to the (representative) direction D1 (as shown in FIG. 6A ), the angle θ2 relative to the reference direction RD gradually decreases, so that the change between the angle θ2 and the initial angle θI decreases. When the vertex A1 of the image area IA2 continues to be located at the screen boundary IE1, as the angle θ2 decreases, the image area IA2 will be enlarged until it reaches the size of the image area IA1.

For another example, please refer to FIG. 6C and FIG. 6D. As the screen 12 rotates clockwise, from the (representative) direction D4 (as shown in FIG. 6D) of the screen 12 to the (representative) direction D3 (as shown in FIG. 6C), the angle θ4 relative to the reference direction RD gradually increases, so that the change amount between the angle θ4 and the initial angle θI decreases. When the vertex A2 of the image area IA4 continues to be located at the screen boundary IE2, as the angle θ4 increases, the image area IA4 will be enlarged until it reaches the size of the image area IA3.

In one embodiment, when the angle is in the first interval (e.g., interval Z1 in FIG. 5 ), the image area of the previous image content displayed on the screen 12 gradually changes from a specified color (e.g., white or gray) to the original color of the previous image content as the change amount of the angle relative to the initial angle decreases. In other words, during the process of rotating the screen 12, a color block of the specified color is displayed. As the change amount continues to decrease, the image content of the display area gradually returns to the previous image content.

In one embodiment, when the angle is in a second interval (eg, interval Z2 of FIG. 5 ), the second image includes an image region that magnifies the content of the previous image as the amount of change of the angle relative to the initial angle increases.

For example, please refer to FIG. 6C and FIG. 6E , assuming that the initial direction ID is downward (corresponding to the long axis of the screen) and the reference direction RD is rightward. That is, the initial angle θI is 90 degrees. As the screen 12 rotates counterclockwise, from the (representative) direction D5 (as shown in FIG. 6E ) of the screen 12 to the (representative) direction D3 (as shown in FIG. 6C ), the angle θ5 relative to the reference direction RD gradually decreases, so that the variation of this angle θ5 and the initial angle θI increases. In addition, the image area IA5 gradually enlarges until it reaches the size of the image area IA3.

For another example, please refer to FIG. 6A and FIG. 6E , assuming that the initial direction ID (corresponding to the long axis of the screen 12) and the reference direction RD are both rightward. That is, the initial angle θI is 0 degrees. As the screen 12 rotates clockwise, from the (representative) direction D5 (as shown in FIG. 6E ) of the screen 12 to the (representative) direction D1 (as shown in FIG. 6A ), the angle θ5 relative to the reference direction RD gradually increases, so that the variation of this angle θ5 and the initial angle θI increases. In addition, the image area IA5 gradually enlarges until it reaches the size of the image area IA1.

In one embodiment, when the angle is in the second interval (e.g., interval Z2 in FIG. 5 ), the image area of the previous image content displayed on the screen 12 gradually changes from a designated color (e.g., white or gray) to the original color of the previous image content as the change amount of the angle relative to the initial angle increases. In other words, during the process of rotating the screen 12, a color block of the designated color is displayed. As the change amount continues to increase, the display area gradually returns to the previous image content.

In one embodiment, when the angle is in the third interval (e.g., interval Z3 in FIG. 5 ), the third image is a geometric color block of a specified color (e.g., white or gray). And the third interval is between the first interval and the second interval. For example, the area Z3 in FIG. 5 is between the areas Z1 and Z2. The geometric shape is, for example, a square, a rhombus, or a circle, but is not limited thereto. In this way, it can be prompted to rotate to the middle area.

In one embodiment, the previous image content includes multiple image contents. These image contents can be different TV channels, videos, pictures or user interfaces. As shown in FIG6C , the image area IA3 includes sub-image areas SIA1 and SIA2. The two sub-image areas SIA1 and SIA2 are used to display different image contents respectively.

In addition to the aforementioned visual prompts, auditory prompts can also be provided. In one embodiment, the controller 16 can use the speaker 15 to emit a corresponding prompt sound according to the angle of the screen 12 relative to the reference direction. The prompt sound is used to guide the rotation of the screen 12. The user can be guided to rotate the screen 12 through the prompt sound.

FIG. 7 is a flow chart illustrating the sound control corresponding to different angles according to an embodiment of the present invention. Referring to FIG. 7 , the prompt sound includes a first sound, a second sound, and a third sound. Different sounds correspond to different (angle) intervals (such as intervals Z1 to Z3 shown in FIG. 5 , but not limited thereto).

When the angle is in the first interval (such as interval Z1 in FIG. 5 ), the controller 16 emits a first sound through the speaker 15 (step S710). When the angle is in the second interval (such as interval Z2 in FIG. 5 ), the controller 16 emits a second sound through the speaker 15 (step S720). When the angle is in the third interval (such as interval Z3 in FIG. 5 ), the controller 16 emits a third sound through the speaker 15 (step S730). The three sounds may differ in frequency, timbre, loudness, music or other factors. Since the three sounds correspond to different (angle) intervals, the contents of the three sounds can indicate the posture of the screen 12.

In one embodiment, both visual and auditory prompts can be provided. In other words, both corresponding images and sounds are provided for the area to which the angle belongs.

For example, Fig. 8 is a schematic diagram illustrating visual and auditory prompts corresponding to different angles according to an embodiment of the present invention. Referring to Fig. 8, zone Z11 is 0 to 40 degrees, zone Z12 is 40 to 50 degrees, and zone Z13 is 50 to 90 degrees.

FIG. 9A is a flow chart illustrating the guidance of rotating from the landscape mode to the upright mode according to an embodiment of the present invention, and FIG. 9B to FIG. 9G are schematic diagrams illustrating the guidance of rotating from the landscape mode to the upright mode according to an embodiment of the present invention. Referring to FIG. 8 and FIG. 9A to FIG. 9G, the controller 16 confirms through the sensor 14 that the posture of the screen 12 is in the first use state, and displays the first display state (step S910). As shown in FIG. 9B, the first use state is the landscape state/mode, and the first display state is also landscape.

The controller 16 detects the counterclockwise rotation of the screen 12 through the sensor 14, and gradually reduces the image area through the screen 12 (step S920), such that the image area shown in FIG. 9C is smaller than the image area shown in FIG. 9B. In order to maximize the visible range, the vertex of the display area can be kept close to or against the display screen boundary of the screen 12. In addition, the sound emitted by the speaker 15 gradually fades out. As shown in FIG. 9D, when the angle x continues to increase to 40 degrees, the image area gradually changes from a horizontal rectangle to a (approximate) square. In addition, in the process from FIG. 9C to FIG. 9D, the original horizontal image gradually changes into a white square block.

When the controller 16 detects through the sensor 14 that the screen 12 rotates counterclockwise beyond a first predetermined angle (for example, 40 degrees), an (approximately) square image area is displayed through the screen 12 (step S930). Then, the angle continues to increase. When the controller 16 detects through the sensor 14 that the screen 12 rotates beyond a second predetermined angle (for example, 50 degrees), the image area is gradually enlarged through the screen 12, and the image area changes from a (approximately) square to a vertical rectangle (as shown in FIG. 9E) (step S940). In addition, the sound emitted by the speaker 15 is silent or nearly silent. Then, the angle continues to increase, and the image area is gradually enlarged. At this time, the image area can be divided into sub-image areas, and different images can be played separately (as shown in FIG. 9F). For example, the upper half secondary image area displays a TV program, and the lower half secondary image area displays a projection screen of an external mobile device. In addition, the speaker 15 emits prompt sounds such as beep, dug, or bell to indicate that the angle spans the area.

When the angle reaches 90 degrees, the controller 16 confirms that it is in the second use state and displays the second display state (step S950). As shown in FIG. 9G , the second use state is the upright state/mode, and the second display state is also upright. For example, different image contents are displayed respectively through multiple sub-image areas. In addition, the speaker 15 can emit a prompt sound such as a beep, a beep, a ring, etc. to prompt that another state has been reached. Alternatively, the speaker 15 can emit a sound corresponding to the image content of a certain sub-image area. For example, a TV or movie sound.

FIG. 10A is a flow chart illustrating the guidance of rotating from the upright mode to the horizontal mode according to an embodiment of the present invention, and FIG. 10B to FIG. 10G are schematic diagrams illustrating the guidance of rotating from the upright mode to the horizontal mode according to an embodiment of the present invention. Referring to FIG. 10A to FIG. 10G, the controller 16 confirms through the sensor 14 that the posture of the screen 12 is in the second use state, and displays the second display state (step S1010). As shown in FIG. 10B, the second use state is the upright state/mode, and the first display state is also upright.

The controller 16 detects the counterclockwise rotation of the screen 12 through the sensor 14, and gradually reduces the image area through the screen 12 (step S1020), such that the image area shown in FIG. 10C is smaller than the image area shown in FIG. 10B. In order to maximize the visible range, the vertex of the display area can be kept close to or against the display screen boundary of the screen 12. In addition, the sound emitted by the speaker 15 gradually fades out. As shown in FIG. 10D, when the angle x continues to decrease to 40 degrees, the image area gradually changes from a vertical rectangle to a (approximate) square. In addition, in the process from FIG. 10C to FIG. 10D, the original vertical image gradually changes into a white square block.

When the controller 16 detects through the sensor 14 that the screen 12 rotates clockwise beyond a first predetermined angle (e.g., 50 degrees), a (approximately) square image area is displayed through the screen 12 (step S1030). Then, the angle continues to decrease. When the controller 16 detects through the sensor 14 that the screen 12 rotates beyond a second predetermined angle (e.g., 40 degrees), the image area is gradually enlarged through the screen 12, and the image area changes from a (approximately) square to a horizontal rectangle (as shown in FIG. 10E) (step S1040). In addition, the sound emitted by the speaker 15 is silent or nearly silent. Then, the angle continues to decrease, and the image area is gradually enlarged. At this time, the image area can display the previous image content in the upper half of the secondary image area of Figure 10B (as shown in Figure 10F). In addition, the speaker 15 emits a prompt sound such as a beep, a buzzer, or a ring to prompt that the angle crosses the area.

When the angle reaches 0 degrees, the controller 16 confirms that it is in the first use state and displays the first display state (step S1050). As shown in FIG. 10G , the second use state is the horizontal state/mode, and the second display state is also horizontal. For example, a single horizontal image content. In addition, the speaker 15 can emit a prompt sound such as a beep, a beep, a ring, etc. to prompt reaching another state. Alternatively, the speaker 15 can emit a sound corresponding to the image content of the image area. For example, TV or movie sound.

FIG. 11 is a flow chart of the return according to an embodiment of the present invention. Referring to FIG. 11 and FIG. 1B , the rotation mechanism 13 further includes a reset chain disposed on the screen 12. When the angle corresponding to the screen 12 is located in the first zone (such as the zone Z1 in FIG. 5 ), the elastic force of the reset chain is used to restore the angle to the initial angle (step S1110). For example, the angle θ2 of FIG. 6B is restored to the initial angle θI, that is, it is restored to the horizontal state shown in FIG. 6A . For another example, the angle θ4 of FIG. 6D is restored to the initial angle θI, that is, it is restored to the horizontal state shown in FIG. 6C .

When the angle corresponding to the screen 12 is located in the second zone (such as zone Z2 in FIG. 5 ), the elastic force of the reset chain is used to change the angle to another angle corresponding to a viewing state different from the initial angle (step S1130). For example, the initial angle θI corresponds to the upright state. The angle θ5 in FIG. 6E is changed to the angle θ1 corresponding to the horizontal state, that is, the horizontal state shown in FIG. 6A . For another example, the initial angle θI corresponds to the horizontal state. The angle θ5 in FIG. 6E is changed to the angle θ3 corresponding to the upright state, that is, the upright state shown in FIG. 6C .

FIG. 12 is a schematic diagram illustrating visual and auditory prompts corresponding to different angles according to an embodiment of the present invention, FIG. 13A is a flow chart illustrating guidance for posture reversion according to an embodiment of the present invention, and FIG. 13B to FIG. 13F are schematic diagrams illustrating guidance for posture reversion according to an embodiment of the present invention. Referring to FIG. 12 and FIG. 13A to FIG. 13F, the controller 16 confirms through the sensor 14 that the posture of the screen 12 is in the first use state, and displays the first display state (step S1310). As shown in FIG. 13B, the first use state is a horizontal state/mode, and the first display state is also horizontal.

The controller 16 detects the counterclockwise rotation of the screen 12 through the sensor 14, and gradually reduces the image area through the screen 12 (step S1320), as shown in FIG. 13C, the image area is smaller than the image area shown in FIG. 13B. In order to maximize the visible range, the vertex of the display area can be kept close to or against the display screen boundary of the screen 12. In addition, the sound emitted by the speaker 15 gradually fades out. As shown in FIG. 13D, when the angle x continues to increase to 40 degrees, the image area gradually changes from a horizontal rectangle to a (approximate) square. In addition, in the process from FIG. 13C to FIG. 13D, the original horizontal image gradually changes into a white square block.

When the controller 16 detects through the sensor 14 that the screen 12 has not rotated more than the first predetermined angle (for example, 40 degrees) but the external force source is only the elastic force of the reset chain (for example, the user's hand leaves the screen 12), the elastic force will drive the screen to rotate clockwise, and the controller 16 gradually enlarges the image area through the screen 12, and the image area changes from a square to a horizontal rectangle (as shown in Figure 13E) (step S1330). In addition, the speaker 15 emits a feedback sound effect. When the angle reaches 0 degrees, the controller 16 confirms that it has returned to the first use state and displays the first display state (step S1340). As shown in Figure 13F, the first use state is a horizontal state/mode, and the first display state is also horizontal. For example, a single horizontal image content. In addition, the speaker 15 can emit a prompt sound such as a beep, a beep, a ring, etc. to prompt the restoration of the original state. Alternatively, the speaker 15 can emit a sound corresponding to the image content of the image area. For example, TV or movie sound.

FIG. 14 is a flow chart of a stay prompt according to an embodiment of the present invention. Referring to FIG. 14 , the prompt image further includes a fourth image. The controller 16 may determine that the stay time maintained by the angle exceeds a time threshold (e.g., 1.5, 2, or 3 seconds) (step S1410). When the stay time of the angle in the third interval (such as the zone Z3 shown in FIG. 5 ) exceeds the time threshold, the controller 16 may display a fourth image on the screen 12. This fourth image is used to guide the angle away from the initial angle. At this time, the controller 16 believes that the screen 12 rotates to the middle area and pauses, and then needs to notify the user to continue rotating the screen 12. The fourth image is, for example, a guide animation. There are many ways to present the guide animation. For example, the fourth image includes multiple guide frames, and each guide frame has different display properties. Display attributes include size, tilt angle, etc.

FIG. 15 is a schematic diagram illustrating visual and auditory prompts corresponding to different angles according to an embodiment of the present invention, FIG. 16A is a flow chart illustrating guidance of intermediate pause according to an embodiment of the present invention, and FIG. 16B to FIG. 16F are schematic diagrams illustrating guidance of intermediate pause according to an embodiment of the present invention. Referring to FIG. 15 and FIG. 16A to FIG. 16F, the controller 16 confirms through the sensor 14 that the posture of the screen 12 is in the first use state, and displays the first display state (step S1610). As shown in FIG. 16B, the first use state is a horizontal state/mode, and the first display state is also horizontal.

The controller 16 detects the counterclockwise rotation of the screen 12 through the sensor 14, and gradually reduces the image area through the screen 12 (step S1620), as shown in FIG. 16C, the image area is smaller than the image area shown in FIG. 16B. In order to maximize the visible range, the vertex of the display area can be kept close to or against the display screen boundary of the screen 12. In addition, the sound emitted by the speaker 15 gradually fades out. As shown in FIG. 16D, when the angle x continues to increase to 40 degrees, the image area gradually changes from a horizontal rectangle to a (approximate) square. In addition, in the process from FIG. 16C to FIG. 16D, the original horizontal image gradually changes into a white square block.

When the controller 16 detects through the sensor 14 that the screen 12 rotates counterclockwise beyond a first predetermined angle (e.g., 40 degrees) but not beyond a second predetermined angle (e.g., 50 degrees) (as shown in FIG. 16E ) and maintains for a predetermined time, the controller 16 displays a guiding animation through the screen 12 (step S1330). As shown in FIG. 16F , the prompt animation is used to prompt the user to indicate the direction of the next rotation until the screen 12 is rotated again. In addition, the speaker 15 emits a pause feedback sound effect.
