Abstract

The invention provides a display used for controlling the gate drive timing sequence, comprising a touch screen, a gate drive signal sending unit, a touch scanning unit, and a timing sequence control unit. The gate drive signal sending unit is used to send more than one gate drive signal. The touch scanning unit is used to send a touch scanning signal. The timing sequence control unit is connected with the gate drive signal sending unit and the touch scanning unit, and is used to control a timing sequence of the gate drive signals and adjust the timing sequence of the touch scanning signal according to the timing sequence of the gate drive signals.

Description

technical field [0001] The invention relates to a method for controlling the gate driving sequence, in particular to a method for controlling the gate driving sequence on an array circuit. Background technique [0002] With the development and progress of liquid crystal display technology, the display quality and appearance design of mobile phones, personal digital assistants (PDAs), digital cameras, computer screens or notebook computer screens have also been greatly improved. [0003] Gate Driver On Array, GOA for short, is to fabricate a scan driver circuit on the array substrate of the existing thin film transistor liquid crystal display to realize the driving method of scanning the scan lines line by line, and is widely used in small and medium size displays. [0004] In addition, the touch technology (Touch Technology) has developed and progressed in recent years, and a variety of touch technologies have been put into mass production. In-cell touch technology with low...
