摘要： Disclosed is a backlight test circuit including N circuit blocks. Each circuit block includes M mini-LED circuits, and each mini-LED circuit includes L mini-LEDs and a switching circuit. The L mini-LEDs are connected in parallel or in serial as a mini-LED set. The switching circuit controls the turning on and the turning off of the mini-LED set according to a control signal. N, M and L are positive integers. During a backlight test, in each circuit block, at least one of the mini-LED sets is turned on. By using this backlight test circuit, the abnormal mini-LED circuit can be found. Thus, a producer can only execute a rework process for the abnormal mini-LED circuit without extra cost.

摘要： The present disclosure relates to a display panel and the polarizer thereof. The polarizer includes a dielectric layer and a wire grid structure array arranged on the dielectric layer. Each of the wire grid structures includes three first wire grid units and a second wire grid unit. The first wire grid units and the second wire grid unit respectively include a plurality of wire grids spaced apart from each other. By configuring the grid-spaces and the duty cycle ratio of the first wire grid unit and the second wire grid unit corresponding to the R sub-pixel, the G sub-pixel, the B sub-pixel, and the W sub-pixel, the white CIE composited by the R sub-pixel, the G sub-pixel, and the B sub-pixel and the white CIE of the W sub-pixel may be matched so as to enhance the white-point drifting issue of the display device.

摘要： The present disclosure provides a controlling method of a display device and the display device. The controlling method may include: detecting whether the display device is at the beginning of the touch panel scanning or during the touch panel scanning; and stopping at least one signal/current scanning operation which is different from the display scanning within the display device if at the beginning of the touch panel scanning or during the touch panel scanning. The present disclosure firstly detects the scanning states of the display device, and stops other scanning operations different from the display scanning when the display device performs the touch panel scanning, which can prevent the display device from being affected by other scar ling operations during the touch panel scanning, thus ensuring the normal operation of the touch panel.

摘要： An LCD includes a backlight module, an array substrate, and a color filter layer. The color filter layer includes a first filter unit, a second filter unit and a black matrix unit. A transmittance rate of the second filter unit is larger than that of the first filter unit. The black matrix layer is connected between the first filter unit and second filter unit. The width of the black matrix unit is larger than that of the third black matrix unit. The width of the black matrix unit facing the first filter unit is larger than that of the black matrix unit facing the second filter unit. This kind of asymmetrical black matrix layer not only best prevents lowering the pixel aperture ratio, but also improves color shift of images when light goes through pixels of low transmittance as pixels of high transmittance are turned off.

摘要： The invention provides a luminance adjustment method and apparatus for RGBW LCD, which uses first and second EOTFs to generate a grayscale luminance lookup table for RGBW LCD, and makes the grayscale-luminance relation in lookup table corresponding to the first EOTF within the grayscale interval between 0 and grayscale threshold; the grayscale-luminance relation in lookup table corresponding to the second EOTF within the grayscale interval between grayscale threshold and 255; the curve slope of the second EOTF greater than the curve slope of the first EOTF within the interval between second luminance threshold and maximum luminance value. By adopting different EOTFs for low and high grayscale intervals, the method considers the poor dark state characteristics of LCD and characteristics of RGBW LCD having higher maximum luminance, and improves the display capability of RGBW LCD in details of high grayscale images.
