Abstract: Display control methods and systems are provided. The display control system includes a panel including a plurality of pixels, and a processor. The processor provides a video signal having a high level to the pixels, and periodically forces at least one of the pixels to be OFF.

Abstract: Monitors with multiple video inputs and one video output are provided. The monitor comprises an output connector and a processor. The processor receives video signals from a plurality of video sources, and combines the video signals to generate a composite video signal. The processor outputs the composite video signal via the output connector.

Abstract: Monitors with cameras are provided. The monitor comprises a display unit, a plurality of cameras, and a processor. Each of the cameras captures at least one picture. The processor receives the pictures from the cameras, and simultaneously displays the pictures in the display unit.

Abstract: A display comprises a base, a display module and a sensing device. The base has a sensing region and the display module has a control device. The sensing device is electrically connected with the control device and the display module is rotatably coupled to the base. The control device can determine that an angle of rotation of the display module with respect to the base according to a corresponding relation between the sensing device and the sensing region of the base.

Abstract: A display includes a monitor module, a base and a shielding apparatus. The base is coupled to the monitor module, and the shielding apparatus is disposed between the base and the monitor module. The shielding apparatus includes a magnetic core and a non-flexible coiled device having a number of fixed shape coils. The coiled device is put through the magnetic core so that the magnetic core is selectively surrounded by at least one of the coils of the coiled device. The monitor module is therefore grounded via the shielding apparatus.

Abstract: An electrostatic discharge (ESD) protection device for a pushbutton module. A printed circuit board (PCB), a keypad unit, and a keypad marking board as well as an insulating sleeve and an electrical conductivity board isolate and discharge generated static electricity.

Abstract: A flat panel display includes a base, a supporting arm, a slide-bracket and a display module. The supporting arm has a first end and a second end. The first end of the supporting arm is hinged to the base so that the supporting arm can rotate relative to the base. The slide-bracket has a first end and a second end. The first end of the slide-bracket is hinged to the second end of the supporting arm so that the slide-bracket can rotate relative to the supporting arm. The display module is connected to the second end of the slide-bracket. Therefore, the display module can move relative to the base along with the movement of the supporting arm, and the display module can slide relative to the slide-bracket.

Abstract: An electronic device with multiple buttons includes a first resistor combination, a second resistor combination, N buttons, and an output node. A first end of the first resistor combination is connected to a high voltage. A second end of the first resistor combination is connected to a third end of the second resistor combination. A fourth end of the second resistor combination is connected to a low voltage. The first resistor combination has p serially connected resistors, and the second resistor combination has q serially connected resistors. The sum of p and q equals M, a positive integer equal to or large than 3. Each button is connected in parallel with at least one resistor. The output node is deposited between the first and the second resistor combinations. The output node outputs an analog signal whose voltage corresponds to the states of the buttons.

Abstract: A liquid crystal display (LCD) device includes a backlight module for providing backlight to the LCD device; a first liquid crystal panel disposed on a top surface of the backlight module for displaying images; and a second liquid crystal panel disposed on a bottom surface of the backlight module for displaying images. The LCD device also includes at least one driver circuit board disposed on at least one side of the backlight module for driving selected cells within the first and second liquid crystal panels in order to display a same image simultaneously.
