Problems solved by technology

[0003] In Cell technology also has its own shortcomings. As far as IC (Chinese: integrated circuit, English full name: integrated circuit) is concerned, it is necessary to integrate the touch drive circuit of the touch emitter electrode (TX) into the drive IC, that is, a separate The TX touch drive circuit is custom-made on a drive chip, so that once there is a problem with the components in the touch drive circuit, the entire drive IC needs to be remade, which is not conducive to cost control, and it will give the display panel a narrow border. bring about hindrance

Embodiment Construction

[0053] The technical solutions in the embodiments of the present invention will be clearly and completely described below in conjunction with the accompanying drawings in the embodiments of the present invention. Obviously, the described embodiments are only a part of the embodiments of the present invention, rather than all the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by those of ordinary skill in the art without creative work shall fall within the protection scope of the present invention.

[0054] The transistors used in all the embodiments of the present invention can be thin film transistors or field effect transistors or other devices with the same characteristics. Since the source and drain of the transistor used here are symmetrical, the source and drain can be interchanged of. In the embodiment of the present invention, in order to distinguish the two poles of the transistor except the gate, one of the poles is called...

Abstract

The embodiment of the invention provides a touch driving unit and a circuit, a display panel and a display device, which relate to the technical field of display and are favorable for realization of narrow side framing of the display panel and realization of effective control on the cost. The touch driving unit comprises a shift control module, a selecting module, a buffer module and an amplitude control module, wherein the shift control module comprises an initial signal end, an output port and at least one clock signal end; the selecting module comprises a first input end, a second input end and an output end; the buffer module comprises an input end and an output end; the amplitude control module comprises an input end, a first level end, a second level end and an output end. The touch driving unit and the circuit, the display panel and the display device of the embodiment are used for manufacturing displays.

Description

Technical field [0001] The present invention relates to the field of display technology, in particular to a touch drive unit and circuit, a display panel and a display device. Background technique [0002] Because In Cell technology (a technology that integrates touch components into the display panel), the display panel can integrate touch functions, making the module lighter and thinner, and has a higher transmittance. At present, more and more products are beginning to use In Cell screens. Most manufacturers now use Hybrid In Cell technology (a hybrid touch technology). In Hybrid In Cell technology, the RX (touch receiving electrode) layer is on the outside of the color film substrate, and the TX (touch emitting electrode) layer Shared with the common electrode layer of the display panel. [0003] In Cell technology also has its own shortcomings. As far as IC (Chinese: integrated circuit, English full name: integrated circuit) is concerned, it is necessary to integrate the tou...
