Description

Used to improve the screen malfunction shutdown mechanism.

This invention relates to an improvement in screen error shut-off mechanism, and particularly to a mechanism designed for use when flipping a multi-mode laptop screen.

Laptops are among the most portable personal information devices, so in addition to providing a fixed power cord, they generally also have a built-in battery pack. This allows users to move around freely without being tied down by a fixed power cord, and can even be used in outdoor areas.

Most laptops currently in use are foldable designs with screens and user interfaces. Furthermore, with advancements in touchscreen technology, some manufacturers have switched to touchscreens as the input interface, allowing users to directly touch the screen to input signals. Some have even gone further, designing laptops that can be flipped 360 degrees and stacked on top of the main unit, allowing users to control the laptop like a tablet. Generally, 360-degree models... It features a design with two bipolar single-output Hall elements. One controls the black screen function when the device is closed at 0°, while the other controls the black screen prevention function when the device is 360° closed. The trigger conditions are both controlled by the magnetic force of the magnets to adjust the sensitivity. However, they can also interfere with each other. For example, when the device is closed (at 0°), the Hall element at 360° may be accidentally triggered, preventing the screen from turning off when the device is closed.

This invention provides a structure to improve the screen malfunction shutdown mechanism. The purpose is to completely avoid misjudgment by Hall effect components by shielding part of the magnetic force with an interference baffle, thereby reducing the occurrence of accidental black screen on flip-up laptops.

The present invention provides a structure for improving screen malfunction shutdown, applicable to a portable electronic device, wherein the structure for improving screen malfunction shutdown includes: a circuit board including a first surface and a second surface, the second surface being opposite to the first surface; a magnetic element having a variable Gaussian value along the axis of the magnetic element; a sensor disposed on the first surface for sensing the Gaussian value; and an interference baffle disposed on the second surface for reducing the Gaussian value sensed by the sensor when the magnetic element is located on the second surface.

In one embodiment of the present invention, the aforementioned portable electronic device is a notebook computer.

In one embodiment of the present invention, the aforementioned notebook computer includes: a first component including an input interface, the sensor, the circuit board, and the interference shield; and a second component connected to the first component and pivoting relative to the first component about a pivot axis, wherein the second component includes a screen interface, a display adjustment unit, and the magnetic unit, the display adjustment unit being adapted to switch between a first display mode, a second display mode, and a third display mode.

In one embodiment of the present invention, when the Gaussian value is greater than a system setting value, the display adjustment unit sets the screen interface to the first display mode; when the Gaussian value is not detected, the display adjustment unit sets the screen interface to the second display mode; and when the Gaussian value is less than the system setting value, the display adjustment unit sets the screen interface to the third display mode.

In one embodiment of the present invention, the aforementioned notebook computer includes a processing unit that controls the display adjustment unit to display or turn off the screen interface based on the Gaussian value obtained by the sensor.

In one embodiment of the present invention, the circuit board described above is, but is not limited to, a printed circuit board (PCB).

Figure 3A is a schematic diagram of a first display mode for improving the screen error shutdown structure according to the present invention; Figure 3B is a schematic diagram of a second display mode for improving the screen error shutdown structure according to the present invention; and Figure 3C is a schematic diagram of a third display mode for improving the screen error shutdown structure according to the present invention.

The present invention provides a structure for improving screen malfunction shutdown, applicable to a portable electronic device 1, wherein the structure for improving screen malfunction shutdown includes: a circuit board 11 including a first surface and a second surface, the second surface being opposite to the first surface; a magnetic unit 12 having a variable Gaussian value along the axis of the magnetic unit 12; a sensor 13 disposed on the first surface for sensing the Gaussian value; and an interference baffle 14 disposed on the second surface for reducing the Gaussian value sensed by the sensor 13 when the magnetic unit 12 is located on the second surface.

In this embodiment, the portable electronic device 1 is a notebook computer.

The notebook computer includes: a first component 2, including an input interface 21, a sensor 13, a circuit board 11, and an interference shield 14; and a second component 3, which is connected to the first component 2 and rotates relative to the first component 2 around a pivot 31. The second component 3 includes a screen interface 32, a display adjustment unit, and a magnetic unit 12. The display adjustment unit is adapted to switch between a first display mode, a second display mode, and a third display mode.

In this embodiment, the display mode of the screen can be adjusted by adjusting the relative position between the magnetic unit 12 and the sensor 13. Referring to Figure 3A, the second component 3 and the first component 2 form a first angle θ1, at which time the magnetic unit 12 and the sensor 13 are at their minimum distance. When the Gaussian value is greater than the system setting value, the display adjustment unit sets the screen interface 32 to the first display mode.

In this embodiment, the magnetic unit 12 and the sensor 13 are located on the same side of the circuit board 11.

Referring to Figure 3B, the second component 3 and the first component 2 form a second angle θ2. The magnetic unit 12 is far away from the sensor 13, so that the sensor 13 cannot obtain the Gaussian value. When the Gaussian value is not detected, the display adjustment unit makes the screen interface 32 the second display mode.

Referring to Figure 3C, after the pivot is flipped, a third angle θ3 is formed between the second component 3 and the first component 2. The magnetic unit 12 approaches the sensor 13, and because the interference baffle blocks the magnetic force, when the Gauss value is less than the system setting value, the display adjustment unit sets the screen interface 32 to the third display mode.

In this embodiment, the magnetic unit 12 and the sensor 13 are located on the same side of the circuit board 11.

In this embodiment, the first included angle θ1 is smaller than the second included angle θ2, and the second included angle θ2 is smaller than the third included angle θ3.

Preferably, the first included angle θ1 can be 0 to 20 degrees, the second included angle θ2 can be 20 to 350 degrees, and the third included angle θ3 can be 350 to 360 degrees.

In summary, the advantages of this invention are that by setting an interference baffle that can interfere with the magnetic force, part of the magnetic force is blocked, allowing the sensor to correctly determine the display mode. This effectively improves the situation where the sensor misjudges when multiple magnets are used at the same time. Furthermore, because the interference baffle is made of metal, it can be used to strengthen the laptop and support the various internal components of the laptop.
