Abstract

The invention provides a touch panel. The touch panel comprises multiple levels of touch drive circuit. Each level of touch drive circuit comprises a first pull-up switch element and a pull-down switch element. The first pull-up switch element comprises a first access end, a first control end and a second pass end, the first access end receives a high reference voltage, the first control end receives an a level gate driving signal, a is an integer, and a is greater than or equal to 1, and the second pass end is used for outputting the current level touch driving signal. The pull-down switch element comprises a third access end, a second control end and a fourth access end, the third access end is connected with the second access end of the first pull-up switch element, the second control end receives a (a+b) level gate driving signal, b is an integer, and b is greater than or equal to 1, and the fourth access end receives a low reference voltage. The invention further provides a display device. The touch panel and the display device provided by the invention are simple in structure, conducive to lightweight and thin design of the device and are high in flexibility.

Description

technical field [0001] The present invention relates to touch display technology, in particular to a touch panel and a display device. Background technique [0002] With the improvement of the function of the display device and people's further requirements for the function, the display device with touch function emerges as the times require and becomes more and more mature. Traditional touch display devices include an add-on touch display device and an integrated touch display device, and the integrated touch display device is further divided into an on-cell type (OnCell) and an in-cell type (InCell). Specifically, an OnCell touch display device refers to placing the touch sensor between the polarizer and the color filter substrate of the display panel, while an InCell touch display device refers to embedding the touch sensor into the pixel of the display panel. in the structure. Compared with OnCell touch display devices, InCell touch display devices have the advantages ...
