Title:
UPDATING METHOD FOR MURA COMPENSATION DATA OF DISPLAY PANEL
Document Type and Number:
WIPO Patent Application WO/2019/109477
Kind Code:
A1
Abstract:
An updating method for Mura compensation data of a display panel. The updating method comprises the steps of: disabling a Mura compensation function of a timing control chip (10) connected to a memory (30), so that a display panel displays an original picture without Mura compensation (S210, S520); disconnecting the timing control chip (10) from the memory (30) (S220, S510); erasing original Mura compensation data stored in the memory (30), and simultaneously obtaining new Mura compensation data according to the original picture displayed by the display panel (S230, S530); and writing the new Mura compensation data to the memory (30) (S240, S540). In the method, erasing of original Mura compensation data stored in the memory (30) and forming of new Mura compensation data are simultaneously performed. In this way, the new Mura compensation data is formed during the erasing time period. Thus, the erasing time period is effectively used, thereby improving the efficiency for producing display panels.
