Display driving circuit, display module, display driving method and electronic equipment

Abstract

The present application provides a display driving circuit, a display module, a driving method of a display screen and electronic equipment, which can improve the display performance of the display screen. The electronic device includes: a display screen, including a first display area and a second display area; the main controller is used to send a first clock signal to the first display drive circuit and the second display drive circuit respectively; the first display drive circuit is used to receive the first clock signal A clock signal; the first display drive circuit is also used to output the first GOA clock signal to the display screen, wherein the first GOA clock signal is generated based on the first clock signal; the second display drive circuit is used to receive the first clock signal ; The second display driving circuit is also used to output a second GOA clock signal to the display screen, wherein the second GOA clock signal is generated based on the first clock signal.

Description

technical field [0001] The present application relates to the field of terminal technology, and in particular to a display driving circuit, a display module, a display driving method and electronic equipment. Background technique [0002] With the rapid development of electronic technology, electronic devices such as smart terminals and tablet computers have greatly changed the way people live and work. In order to meet various needs of users for entertainment, office work, watching videos or browsing webpages, etc., the area of ​​display screens of electronic devices is designed to be larger and larger, and the performance requirements for display driving circuits are also getting higher and higher. Therefore, there may be situations where the capability of a single display driving circuit is insufficient to drive the display panel. In this case, multiple display driving circuits can be used to drive the display screen, and this driving structure can be called a multi-disp...

AI Technical Summary

Problems solved by technology

The clock signal in the row scanning each row of pixels is generated based on the internal clock signal of each display driving circuit, and clock synchronization is not performed.

Due to the error in the internal clock frequency of different display driving circuits, it will affect the display performance of the display
