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: A data signal delay circuit and delay method and a display device are disclosed. The data signal delay circuit includes a feedback signal generation sub-circuit, a compensation signal generation sub-circuit, and a control sub-circuit. The feedback signal generation sub-circuit is configured to generate a feedback signal based on a first level signal from the first level signal terminal and a second level signal from the second level signal terminal under the control of a gate drive signal from a scan signal line currently being scanned. The compensation signal generation sub-circuit is configured to generate a compensation signal based on the feedback signal and a data enable signal from the data enable signal line. The control sub-circuit is configured to delay a data enable signal of the data enable signal line in a next cycle based on the compensation signal.

Abstract: The present disclosure relates to a backlight module. The backlight module includes a back plate, a circuit layer, a light source and a plurality of connecting leads. The back plate has a first surface and a second surface which are opposite to each other, wherein the back plate is provided with a plurality of through holes penetrating the first surface and the second surface. The circuit layer is disposed on the first surface to form a driving circuit for a light source. The light source is disposed on a surface of the circuit layer away from the back plate and formed integrally with the back plate. The plurality of connecting leads pass through the plurality of through holes one-to-one for connecting the circuit layer and a main circuit board.
