Abstract: A driver, a display device, and an optical compensation method thereof are provided. The display panel includes sub-pixels arranged in an array. The method includes: receiving an initial gray level of each sub-pixel of a picture to be displayed; determining whether each sub-pixel satisfies a preset determination condition based on the initial gray level of each sub-pixel; if an absolute value of a difference between the initial gray levels of two sub-pixels electrically connected to a same data line and located in two adjacent rows is greater than a preset threshold, it is determined that a sub-pixel in a next row satisfies the preset determination condition; and, in response to determining that a sub-pixel satisfies the preset determination condition, acquiring a first compensation parameter of the sub-pixel, and compensating the initial gray level of the sub-pixel based on the acquired first compensation parameter.

Abstract: Disclosed includes an apparatus, a drive method, a display panel, and a display device. The apparatus may comprise a drive transistor, a light emitting device driven by the drive transistor and a comparator. The comparator may have a first input coupled to a pixel voltage, a second input coupled to a reference voltage, a first control terminal coupled to a first control voltage, a second control terminal coupled to a second control voltage, and an output coupled to a gate of the drive transistor. The comparator may be configured to output the first control voltage to the output during a first time period in which the pixel voltage is not smaller than the reference voltage and output the second control voltage to the output during a second time period in which the pixel voltage is smaller than the reference voltage.

Abstract: A method for processing image data with reduced transmission bandwidth is provided. The method includes receiving a first set of data for image in a first resolution and receiving a center coordinate. The method further includes determining a high-definition region including an area and a boundary centered on the center coordinate. Additionally, the method includes rendering the first set of data based on the center coordinate and the area of the high-definition region to obtain a first subset of data. Furthermore, the method includes rendering a set of data compressed from the first set of data to obtain a second subset of data beyond the boundary. Moreover, the method includes transmitting a second set of image data to the display panel combining the first subset of data for display image in the first resolution and the second subset of data to display image in the second resolution.

Abstract: There are provided a pixel charging method, a circuit, a display device and a computer storage medium. The method includes: acquiring a gray-scale value of each row of sub-pixels in an image frame of an image to be displayed; determining a charging time of each row of the sub-pixels according to the gray-scale value thereof; and charging each row of the sub-pixels according to the charging time thereof when a display panel displays the image frame. The charging time of each row of sub-pixels is determined according to the gray-scale value of each row of the sub-pixels, so as to reduce a charging rate difference between two rows of sub-pixels which have a relatively larger gray-scale value difference therebetween, and achieve an effect of improving the uniformity of the charging rates of all rows of sub-pixels in the display panel.
