    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: The present application discloses a gate driver control circuit including an encoder configured to encode instruction information to obtain a coded instruction and to transmit the coded instruction. The gate driver control circuit further includes a decoder coupled to the encoder and configured to decode the coded instruction to obtain the instruction information. Additionally, the gate driver circuit includes at least one multiplexer coupled to the decoder. Each multiplexer is configured to receive a first set of multiple timing-control signals and the instruction information, to adjust the first set of multiple timing-control signals to a second set of multiple timing-control signals based on the instruction information, and to output the second set of multiple timing-control signals. The gate driver control circuit further includes at least one gate-array sub-circuit. Each gate-array circuit is configured to output multiple row-scanning signals in response to the second set of multiple timing-control signals.

    Abstract: The disclosure relates to a drive control method and assembly, and a display device. A drive control method for a timing controller includes generating a point-to-point configuration instruction including an identity identification of a source driver, wherein the source driver is any of a plurality of source drivers, sending the point-to-point configuration instruction via first signal lines, and receiving a configuration response instruction sent by the source driver via the one of the first signal lines. The configuration response instruction is sent by the source driver after executing the point-to-point configuration instruction in response to detecting that the identity identification in the instruction is its own identity identification.

    Abstract: This application relates to an encoding method and device, a decoding method and device, and a signal transmission system. The encoding method includes: encoding 8-bit data corresponding to a to-be-encoded byte of to-be-transmitted data into 9-bit data, the to-be-transmitted data comprising at least one to-be-encoded byte; detecting the first digit of data of the 9-bit data and a previous digit of data adjacent to the first digit of data, when the to-be-encoded byte is not the first byte of the to-be-transmitted data; inverting the 9-bit data and then adding a tenth digit of data for indicating that the inverted 9-bit data has undergone an inversion operation behind the inverted 9-bit data to obtain 10-bit data, when the numerical value of the first digit of data is the same as that of the previous digit of data; and adding a tenth digit of data for indicating that the 9-bit data has not undergone an inversion operation behind the 9-bit data to obtain 10-bit data, when the numerical value of the first digit of data is different from that of the previous digit of data.

    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.
