Touch display drive circuit and drive method and display device thereof

Abstract

The invention provides a touch display drive circuit and a drive method and a display device thereof. The circuit comprises a touch module and a display drive module. The display drive module is connected with a data line, a fist scanning lie, a second scanning line, a control line, a first voltage source, a third voltage source and a fourth voltage source, and the display drive module is used for carrying out compensation on a drive unit, writing in data signals input by the data line, outputting the data signals to the touch module and driving a luminescent unit to give out light under the control of signals input by the data line, the first scanning line and the second scanning line. The touch module is connected with the first scanning line, the second scanning line, a reading line and a second voltage source, and the touch module is used for receiving the data signals input by the display drive module under the effect of the signals input by the first scanning line and the second scanning line to carry out reconfiguration on the touch module. When touches occur, the touch module provides touch signals, and the reading line confirms the positions where the touches occur according to collected touch signals.

Description

technical field [0001] The present invention relates to the field of display technology, in particular to a touch display driving circuit, a driving method thereof, and a display device. Background technique [0002] Organic light-emitting display (Active Matrix Organic Light Emitting Diode, AMOLED) is one of the hotspots in the field of flat panel display research today. Compared with Thin Film Transistor-Liquid Crystal Display (TFT-LCD), OLED has low energy consumption, Due to the advantages of low production cost, self-illumination, wide viewing angle and fast response speed, OLEDs have begun to replace traditional LCD displays in display fields such as mobile phones, PDAs, and digital cameras. Pixel drive circuit design is the core technical content of AMOLED display, which has important research significance. [0003] At present, the in-cell touch technology has been successfully applied to LCD displays, and the first-line manufacturers in the industry have successfull...

AI Technical Summary

Problems solved by technology

[0003] At present, the in-cell touch technology has been successfully applied to LCD displays, and the first-line manufacturers in the industry have successfully mass-produced them. However, due to the limitation of patented technology and yield rate, it is still unable to completely replace Add-on and Add-on in the market on a large scale.
