Abstract: A linear compensation method of a touch panel is utilized to a touch control computer system. According to the method, a compensation reference table, including reference temperatures and reference surface resistances at pre-determined reference points having known coordinates at the reference temperatures, is obtained at first. Then, a set of user calibration resistance at the pre-determined reference points is obtained through a user calibration process, so as to obtain ratios of the user calibration resistances to interpolation surface resistances as correction weights. Under different temperature, interpolation surface resistances corrected by utilizing the correction weight to derive the current correction surface resistances that are corrected and nearly identical to actual surface resistances. Therefore, relatively precise coordinates are obtained through resistance-coordinate conversion process.

Abstract: A liquid crystal display equipped with an overheat protection device and overheat protection method is disclosed. When a temperature sensor measures that the temperature of a LED (Light-Emitting Diode) backlight module is overheated and possibly will cause damage, the overheat protection device descend the luminance of the LED backlight module to lower the temperature inside the liquid crystal display.

Abstract: A portable electronic device includes a flat display, a transparent window, an optical element, an optical zoom lens set and an image sensing element. The flat display includes a display panel with a viewing direction. The transparent window, the optical element, the optical zoom lens set and the image sensing element are all configure in the outer frame of the flat display. The transparent window and the optical element correspond to each other and align in the viewing direction. The optical zoom lens set includes multiple lenses configured at one side of the optical element. The lenses move along a focusing direction to modify the focusing length. The focusing direction is substantially perpendicular to the viewing direction.

Abstract: An edge-light backlight assembly is provided, which includes a light guide and a protruding part. The protruding part is provided for receiving light from various directions. The light received by the protruding part directly enters or is reflected to enter the light guide, and then the light leaves the light guide to provide backlight. Light sources are arranged to project light to the protruding part in different directions, such that the light sources can be disposed dispersedly to reduce the thickness of the light guide and heat generated is distributed over a large area.

Abstract: A display system and driving method thereof are capable of outputting a low luminance of red light, especially through descending a color level of red signals when displayed. The display system includes a display device and an image processing device. The image processing device outputs the red signals to the display device for displaying thereon. The color level of red signals is descended by a display chip or a switch device to allow the display device to display images with low luminance of red light, so that the display device is viewable through a night-vision device.
