Problems solved by technology

In order to ensure that there is no split-screen phenomenon when displaying a large-size display panel, the gamma voltages output by each driver chip must be consistent. However, due to reasons such as manufacturing process and circuit structure, the gamma voltage output by each driver chip is inconsistent. It is easy to cause split screen phenomenon, resulting in poor display effect and poor user experience

Abstract

The embodiment of the present invention discloses a drive circuit of a display panel, a display module and a compensation method thereof, and a display device. The present invention adopts a TCON circuit board with multiple groups of reference voltage output terminals to independently supply voltage through corresponding groups of reference voltage input lines. Each driver chip inputs a reference voltage, that is, each driver chip receives an independent reference voltage signal, so that the reference voltage output by the TCON circuit board corresponding to each driver chip can be adjusted, so that the reference voltage received by all driver chips is the same, so that the All driver chips output the same gamma voltage, which avoids inconsistent gamma voltages output by different driver chips due to factors such as different impedances of the reference voltage input lines of each group, which in turn leads to split-screen display on the display panel and improves display quality.

Description

technical field [0001] The present invention relates to the technical field of display modules, and in particular, to a driving circuit of a display panel, a display module and a compensation method thereof, and a display device. Background technique [0002] With the continuous development of display technology, large-sized display panels are more and more favored by people. The driver chip (source IC) is spliced ​​to drive the display panel. Each driver chip is independent and is provided with its own gamma circuit, which is used to generate a gamma voltage to drive the display panel to display. In order to ensure that there is no split screen phenomenon when displaying large-size display panels, the gamma voltage output by each driver chip needs to be consistent. However, due to the manufacturing process, circuit structure and other reasons, the gamma voltage output by each driver chip is inconsistent. During the display process It is easy to cause split screen phenomen...
