Abstract

The invention provides a display device and a speckle removing system and a speckle removing method thereof. The speckle removing system comprises N mutually cascaded time sequence controllers, N being an integer greater than or equal to 2; a flash memory chip, used for storing speckle elimination data of the display device; wherein the flash memory chip and the time schedule controller are sequentially connected through N buses, and the flash memory chip is connected with the first time schedule controller through a first bus; in the Lth stage, the Lth time sequence controller is connected with the flash memory chip through the former (L-1) time sequence controllers and the former L buses, Lth speckle elimination data in the flash memory chip is read, and L is an integer larger than or equal to 1 and smaller than or equal to N. According to the speckle removing system, the time sequence controller located at the rear position is connected with the flash memory chip in a timing mode through the time sequence controller located at the front position and the bus in respective stages, wiring between the time sequence controller and the flash memory chip is reduced, circuits are simplified, manufacturing cost is reduced, the area of a control panel is released, and layout and wiring of the control panel are facilitated.

Description

technical field [0001] The present application relates to the field of display, in particular to a display device, a speckle elimination system and a speckle elimination method thereof. Background technique [0002] Due to the flaws in the display panel manufacturing process, the display panel often has various mura (the uneven brightness of the display panel, resulting in various spots), so the timing controller is required to perform demura processing on the display panel. . [0003] In the existing technology, such as figure 1 As shown, the display device includes at least two timing controllers 102, respectively corresponding to different areas of the display panel 101, the timing controllers 102 are cascaded with each other, and the timing controllers 102 are respectively connected to the gating module 104, through the gating module 104 The selective conduction of the flash memory chip 103 realizes the connection with the flash memory chip 103, so as to read the speck...
