Abstract

The invention provides a display driving circuit, a display module, a driving method of a display screen and electronic equipment. The display performance of the display screen can be improved. The electronic equipment includes: a display screen including a first display area and a second display area; a main controller used for sending a first clock signal to a first display driving circuit and asecond display driving circuit respectively; the first display driving circuit used for receiving a first clock signal and outputting a first GOA clock signal, generated based on the first clock signal, to the display screen; and the second display driving circuit used for receiving the first clock signal and outputting a second GOA clock signal, generated based on the first clock signal, to thedisplay screen.

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...
