    Abstract: This disclosure relates to a liquid crystal display and a display device. A plurality of photosensitive detectors is arranged in the frame region of the liquid crystal display panel. Light intensity distribution in the display region is estimated by a light intensity estimation module based on the light intensity detected by each photosensitive detector. Light intensity in a position corresponding to each light emitting pixel of the backlight source is determined based on the light intensity distribution in the display region estimated by the light intensity estimation module. Depending on the determined light intensity in a position corresponding to each light emitting pixel of the backlight source, luminance of the light emitting pixel in this corresponding position is controlled by a backlight driving circuit.

    Abstract: An image processing method and device, storage medium and computer device are provided. The method includes: generating an original gray scale image of an original image; performing a histogram equalization process on the original gray scale image to obtain an equalized gray scale image; generating decision factor distribution image, wherein the decision factor distribution image includes a first marked region including a region where pixels that are adjacent in position and have standard deviations smaller than set value in the original image are located, and second marked region; obtaining final gray scale image according to original gray scale image, equalized gray scale image and decision factor distribution image. Gray scale values of pixel corresponding to second marked region and first marked region in final gray scale image are respectively gray scale values of corresponding pixel in equalized gray scale image and original gray scale image; and restoring a processed image.

    Abstract: A signal transmission method and related timing controller, source driver and display device are disclosed. The method includes scrambling a signal to be transmitted by a transmitting unit to obtain a scrambled signal. Each frame of the scrambled signal includes at least one first identification signal sequentially arranged in time domain, and a number of the first identification signals in the scrambled signal is equal to a number of the first identification signals in the scrambled signals of other transmitting units in the plurality of transmitting units. The method includes transmitting the scrambled signal to a corresponding receiving unit, where the first identification signal is configured to indicate linear feedback shift registers of the transmitting unit and the corresponding receiving unit to perform a reset operation, and after each collective reset operation is completed, the corresponding receiving unit outputs a display signal to the display panel.
