Embodiment 1

[0034] The gate line drive circuit is used to provide the signal to open the gate line. It can form an external drive chip (that is, a gate driver) alone, or directly integrate the gate drive circuit on the array substrate to replace the external drive chip and become an array substrate row. Drive (Gate Driver on Array, GOA) unit, the application of this technology can not only reduce the production process procedures, reduce product costs, improve integration, but also achieve a symmetrical and beautiful design on both sides of the panel, and also save the gate circuit ( Gate IC) bonding (Bonding) area and fan-out (Fan-out) wiring space, so as to realize the design of narrow border, improve the production capacity and yield rate.

[0035] An embodiment of the present invention provides a gate line driving circuit, such as figure 1 As shown, the gate line driving circuit includes a power supply input pin (such as figure 1 The positive power supply input pin 10) in the power s...

Embodiment 2

[0049] Similarly, an embodiment of the present invention also provides a circuit for outputting the emission control signal EM, including: a second power input pin for inputting an effective voltage for controlling the emission control transistor in the pixel area to be turned on, and the second power input pin is at An effective voltage is input in the display phase, and a synchronous driving signal is input in the touch phase.

[0050] The circuit provided in this embodiment is used to output the emission control signal EM, and its principle is similar to the above gate drive circuit: the circuit used to output the emission control signal EM is generally provided with a second power input pin for inputting the control pixel area The effective voltage of the emission control tube is turned on. In the time domain where the emission control tube needs to be controlled in the pixel area, the thin film transistor in the control circuit is turned on to form an output channel and ou...

Abstract

The invention discloses a gate line drive circuit, a circuit for outputting emission control signals and a touch display device, which relate to the display field and solve the problem that the existing gate line drive circuit cannot output synchronous drive signals. The gate line driving circuit of the present invention includes a power input pin for inputting an effective voltage for controlling the switching off of the pixel area switch tube, the power input pin inputs the effective voltage during the display phase, and inputs a synchronous driving signal during the touch phase.

Description

technical field [0001] The present invention relates to the display field, in particular to a gate line driving circuit, a circuit for outputting emission control signals and a touch display device. Background technique [0002] Organic Light Emitting Diode (AMOLED) is one of the hot spots in the field of flat panel display research today. Compared with liquid crystal displays, OLED has the advantages of low energy consumption, low cost, self-illumination, wide viewing angle and fast response speed. Currently, OLEDs have begun to replace traditional liquid crystal displays in display fields such as mobile phones, PDAs, and digital cameras. [0003] At present, the integration of self-capacitive in-cell touch technology and AMOLED display technology, so as to embed the touch function into the AMOLED screen body, is currently the main research direction of panel manufacturers. According to the principle of embedded self-capacitive touch, the touch detection unit (touch sensor...
