Description

Display module, electronic device using same and display method thereof

technical field

The present invention relates to a display module, in particular to a display module which generates a corresponding current combination according to the use status of the electronic components in the electronic device to control the light-emitting components to present a continuous display effect, an electronic device using the same and its Show method.

Background technique

At present, many new-generation electronic devices, such as common personal computers or notebook computers, can not only display the used space capacity or remaining space capacity of electronic components (such as hard disk or memory) in the electronic device through computer software, but also The current usage status of the space capacity can be displayed by means of hardware. For example, the display module of the electronic device can display the used/remaining space capacity of the electronic components in segments by controlling the light-emitting states of a plurality of light-emitting diodes.

Please refer to FIG. 1A . FIG. 1A is a schematic diagram of a conventional display module segmentally displaying the currently used/remaining space capacity of electronic components. As shown in Figure 1A, the display areas 10A~10C emit bright light and the display areas 10D~10E do not emit light. Therefore, according to the situation displayed by the display module, it can be known that the space capacity used by the electronic components has reached 60%, that is, the remaining space The capacity is about 40%.

FIG. 1B is a schematic diagram corresponding to the lighting situation of the light-emitting diode shown in FIG. 1A . As shown in FIG. 1B, since the light emitting diodes 12A~12E correspond to the display areas 10A~10E respectively, and the current space capacity of the electronic components has reached 60%, the light emitting diodes 12A~12C will emit light, and the light emitting diodes 12D~12C will emit light. 12E does not.

Although the traditional segmented display method above can roughly display the currently used/remaining space capacity of electronic components, however, there are still many shortcomings that need to be overcome in practical applications.

First of all, due to the one-to-one arrangement between each light-emitting diode and each display area in the traditional display module, when the display module needs more accurate multi-segment display, it is necessary to set the same number of light-emitting diodes, resulting in the production cost of the display module A substantial increase. For example, assume that the display module wants to display the remaining/used capacity of the electronic components in ten segments, that is, the display module includes ten display areas, and the display module also needs to be equipped with the same number of ten light-emitting diodes to achieve the desired result. The desired segment display effect. As users have higher and higher requirements on the fineness of the display effect, the display module needs more light emitting diodes, so its production cost also increases accordingly.

In addition, adopting such a segmented display method often results in the formation of dark bands between adjacent light-emitting display areas. For example, in FIG. A dark band D2 is formed between the display regions 10B and 10C. Because the contrast between the light-emitting bright band and the dark band is too obvious, the entire luminous display area appears to be discontinuous in appearance, thus affecting the design aesthetics of its overall shape and the perception of users.

In addition, the display module can be disposed in the electronic device and coupled to the electronic components, or coupled to the electronic components in the electronic device from outside the electronic device, without certain limitations.

Please refer to FIG. 2 . FIG. 2 is a schematic diagram showing the appearance of a display module according to a first embodiment of the present invention. As shown in FIG. 2 , the display module 2 includes a light guide unit 21 and a casing 22 . Wherein, the light guide unit 21 has a light incident surface 214 , a light exit surface 211 and a surface treatment layer 210 , and the surface treatment layer 210 covers the light exit surface 211 . In practical applications, the surface treatment layer 210 is not limited to covering the light-emitting surface 211 , and can also be formed on the light-emitting surface 211 by different surface treatment methods, such as atomization treatment or embossing treatment. In addition, the surface treatment layer 210 can also cover the light incident surface 214 , or be formed on the light incident surface 214 by different surface treatment methods, and even the material of the light guide unit 21 itself is not limited.

The light emitting diodes 220A~220D are disposed on the housing 22 and adjacent to the light incident surface 214 of the light guide unit 21, so that the light emitted by the light emitting diodes 220A~220D can be transmitted to the light incident surface 214 of the light guide unit 21, and from the light incident surface 214 enters the light guide unit 21. The control unit 222 is disposed in the casing 22 and is coupled to the LEDs 220A-220D for controlling whether the LEDs 220A-220D emit light and the intensity or brightness of the light. In addition, the light guide unit 21 is also provided with holes 212A- 212C, and the positions of the holes 212A- 212C are respectively arranged between every two adjacent LEDs, but not limited thereto.

Please refer to FIG. 3. FIG. 3 shows that the display module 2 in FIG. 2 detects the use status of the electronic component 30 in the electronic device 3 and receives the status signal S from the electronic component 30, and then generates a corresponding signal according to the status signal S. A schematic diagram of controlling the current combination I _{A -ID} to the light emitting diodes 220A - 220D. As shown in FIG. 3, the control unit 222 of the display module 2 is coupled to the electronic component 30 in the electronic device 3. After the control unit 222 receives the status signal S from the electronic component 30, the control unit 222 will generate The control current combinations I _A ~ _ID corresponding to the LEDs 220A ~ 220D are respectively transmitted to the LEDs _220A ~ _220D for controlling the LEDs 220A ~ 220D. Then, the light emitted by the light emitting diodes 220A~220D can be emitted to the light guide unit 21 and present a continuous display effect, that is, the above-mentioned light passes through the light incident surface 214, the light exit surface 211 and the surface treatment layer 210 of the light guide unit 21. The display area presented later is continuous, which can effectively improve the deficiency of the prior art.

In fact, the display effect can correspond to the size of the display area where the light emitted by the light emitting diodes 220A~220D passes through the light emitting surface 211 and the surface treatment layer 210, and can also correspond to the size of the display area where the light emitted by the light emitting diodes 220A~220D passes through the light emitting surface 211 and the surface treatment layer. A display brightness level of the processing layer 210 is controlled, and the display brightness level corresponds to a combination of currents for controlling the light emitting diodes 220A˜ 220D. Therefore, in addition to presenting a continuous display effect, the present invention can also control the strength and darkness of the display brightness by adjusting the current combination of the light emitting diodes 220A-220D. In addition, the status signal S may include usage status information of the electronic component 30 , such as the current remaining capacity of the electronic component 30 or the size of the used capacity. As for the electronic component 30, it may be an electronic device such as a hard disk, a memory, or a charger, but it is not limited thereto.

Next, different ways in which the control unit 222 of the display module 2 respectively generates control current combinations I _{A -ID} corresponding to the light emitting diodes 220A - 220D according to the state signal S will be further discussed.

Please refer to FIG. 4A , which is a functional block diagram of the control unit 222 . As shown in FIG. 4A , the control unit 222 includes a control element 2220 and integrating circuits 2222A˜ 2222D. Wherein, the control element 2220 has a look-up table 22200, and the look-up table 22200 stores optical simulation results; the integration circuits 2222A-2222D are circuits with an integration function, and their types are not limited.

In fact, the results of the optical simulation are simulated by optical simulation software to obtain the corresponding relationship between the use state of the electronic component 30 , the combination of currents for controlling the light emitting diodes, and different display effects. Wherein, the optical simulation software may be lighttools, Tracepro or other software with optical simulation functions, and there is no certain limitation. It is worth noting that there are many factors that affect the optical simulation results. In addition to the influence of the number and position of the light emitting diodes 220A-220D and the light guide unit 21, the optical simulation results will also be affected by the number and position of the holes 212A-212C, or the surface The processing layer 210 covers the light incident surface 214 or the light exit surface 211 and other factors.

When the control component 2220 receives the status signal S from the electronic component 30, the control component 2220 will find out the current status corresponding to the electronic component 30 from the comparison table 22200 according to the current status information of the electronic component 30 contained in the status signal S. What is the size of the control current combination I _A ~ I _D in the use state.

For example, FIG. 4B shows a comparison table of the used space capacity of the electronic component 30 and the size of the control current combination I _A ~ I _D obtained after optical simulation. It is assumed that the control component 2220 knows the electronic component 2220 according to the state signal S. The currently used space capacity of the element 30 is 40%, and the control element 2220 can obtain the corresponding control current combinations _IA - _ID from the comparison table, which are 3mA, 5mA, 3mA and 0 respectively.

Returning to Fig. 4A again, when the control element 2220 has obtained the values of the control current combination _IA ~ _ID from the comparison table, the control element 2220 will respectively output the pulse width modulation corresponding to the control current combination _IA ~ _ID The signal PWM _A ~PWM _D is sent to the integrating circuit 2222A~2222D and integrated by the integrating circuit 2222A~2222D to generate a combination of control currents _IA ~ _ID to control the light emitting diodes 220A~220D.

In fact, when the pulse widths W _A ~ W _D of the pulse width modulation signals PWM _A ~ PWM _D output by the control element 2220 are larger, the corresponding equivalent voltages V _A ~ V _D are also larger. When the value is fixed, the combination of the control current _I A ~ _ID is larger, therefore, the corresponding relationship between the pulse width W _A ~W _D and the control current combination I _A ~ _ID can also be recorded in the comparison table , to be read by the control unit when required. As shown in FIG. 4C , assuming that the magnitude sequence of the control current combination I _A ~ I _D is: I _A < I _B < I _C < I _D , then the pulse width modulation signals PWM _A ~ PWM _D output by the control element 2220 The magnitude sequence of the pulse width W _A ~W _D is: W _A <W _B <W _C <W _D . Therefore, the control element 2220 can adjust the size of the control current for controlling the LEDs 220A~220D by outputting pulse width modulation signals with different pulse widths, so as to change the lighting conditions of the LEDs 220A~220D (for example, the LEDs 220A~220D Whether 220D emits light or light-emitting diodes 220A~220D luminous intensity and brightness), and presents various continuous display effects.

In addition to the above-mentioned generation method of the control current combination _IA ~ _ID , FIG. 5A shows a functional block diagram of another embodiment of the control unit in FIG. 3, that is, another control current combination _IA ~I How _D is produced. As shown in FIG. 5A , the control unit 222 includes a control element 2220 and logic circuits 2224A˜ 2224D. When the control component 2220 receives the status signal S from the electronic component 30, the control component 2220 will find out the current status corresponding to the electronic component 30 from the comparison table 22200 according to the current status information of the electronic component 30 contained in the status signal S. The value of the control current combination I _A ~ I _D in the use state.

Next, the control element 2220 outputs the corresponding general-purpose input and output signals GPIO _A to GPIO _D to the logic circuits 2224A to 2224D according to the control current combinations _{I A} to ID respectively, _and then the logic circuits 2224A to 2224D respectively output the control current combinations I _A ~ _ID are connected to the light emitting diodes 220A ~ 220D to control the light emitting diodes 220A ~ 220D.

As for the detailed circuit structure of the logic circuit, please refer to FIG. 5B. FIG. 5B is a functional block diagram of the logic circuit in FIG. 5A, which is a circuit diagram of an embodiment of the logic circuit 2224A. As shown in FIG. 5B, the logic circuit 2224A It includes switch elements SW1-SW3 and resistance elements R1-R3. In fact, the types and numbers of the switching elements and the resistive elements included in the logic circuit 2224A can be determined according to actual requirements, and are not limited to this example.

In this embodiment, the general-purpose input and output signal GPIO _A output from the control element 2220 to the logic circuit 2224A changes the equivalent resistance value under a specific working voltage V by controlling the switching elements SW1-SW3 to be turned on or off. In order to adjust the magnitude of the control current I _A finally output by the logic circuit 2224A.

For example, assuming that the logic circuit 2224A turns on the switch elements SW1 and SW3 and turns off the switch element SW2 according to the general-purpose input and output signal GPIO _A , that is, only a path is formed between the resistance element R2 and the contact N, and the resistance elements R1 and R3 and the contact N Therefore, under the premise that the LEDs 220A-220D are grounded and the resistance of the switching element SW2 is negligible, the control current I _A finally output by the logic circuit 2224A is (V/R2).

On the other hand, assuming that the logic circuit 2224A turns off all the switch elements SW1~SW3 according to the general input/output signal GPIO _A , the resistance elements R1~R3 and the contact N are all paths, so the control current I _A finally output by the logic circuit 2224A is It is (V/R1)+(V/R2)+(V/R3). At this time, the control current (V/R1)+(V/R2)+(V/R3) output by the logic circuit 2224A will be larger than the above (V/R2), so the luminance of the light emitting diode 220A will also increase at this time. higher.
