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

Abstract

The invention relates to a display device driving unit and a driving method thereof; the driving device comprises the following units: a first substrate including a storage unit, the storage unit is electrically connected with a display module and stores display parameters of the display module, and the display parameters comprise a gamma correction code, a common electrode voltage setting code, and a display module uneven brightness distribution compensation module code; a second substrate including a control module electrically coupled to the storage unit, the control module reads the display parameters stored in the storage unit and adjusts the driving parameters of the display module, and the second substrate is electrically coup-led to the first substrate through a serial peripheral equipment interface; an integrated circuit bus electrically respectively coupled to a sequential control unit and a programmable gamma correction buffer circuit unit. The driving device can enable a circuit board and a control panel to separate and can improve the panel inter-chip differences caused by making processes, thus improving the whole product quality without adding extra packaging or operation difficulties.

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...
