Display device driving device and driving method thereof

Abstract

Disclosed are a driving apparatus (11) and a driving method for a display apparatus. The driving apparatus (11) comprises: a first substrate (50), comprising a storage unit (110) electrically connected to a display module (160), the storage unit (110) storing display parameters of the display module (160), and the display parameters being a Gamma correction code (112), a common electrode voltage setting code (114) and a display module brightness distribution unevenness compensation module code (116); and a second substrate (60), comprising a control module electrically coupled to the storage unit (110), the control module reading the display parameters stored in the storage unit (110), and adjusting driving parameters of the display module (160), wherein the second substrate is electrically coupled to the first substrate (50) by means of a serial peripheral device interface (150); and an integrated circuit bus (140) respectively electrically coupled to a timing control unit (120) and a programmable Gamma correction buffer circuit unit (130). A type of machine, the circuit board and the control board of which are separated, can also improve the difference between panels caused by a process, thus enhancing the overall product quality, without additionally increasing the difficulty of packaging, operation, etc.

Description

technical field [0001] The invention relates to a method for improving the performance of a driving device of a display device, in particular to a driving device of a display device and a driving method thereof. Background technique [0002] Liquid crystal display (Liquid Crystal Display, LCD) has been widely used recently. With the improvement of drive technology, it has the advantages of low power consumption, thin and light weight, and low voltage drive. It has been widely used in video recording and playback Video machines, notebook computers, desktop monitors and various projection equipment. [0003] And the liquid crystal display device generally has a gate driving circuit, a source driving circuit and a pixel array. There are multiple pixel circuits in the pixel array, and each pixel circuit is turned on and off according to the scan signal provided by the gate drive circuit, and displays a data frame according to the data signal provided by the source drive circuit...

AI Technical Summary

Problems solved by technology

The problem with this is: because of the manufacturing process, each panel will be slightly different. If you want each panel to achieve the best quality, you need each panel to be equipped with an independent gamma Correction, common electrode voltage setting, etc., make the open components correspond to the control board one by one, but this is a problem for packaging, transportation and assembly
