Abstract

The invention provides a self-capacitance touch display panel and a driving method thereof. The self-capacitance touch display panel comprises a first base plate, a second base plate and a liquid crystal layer, wherein the first base plate comprises a first substrate, a touch electrode layer, a driving circuit layer and a pixel electrode layer, the touch electrode layer is arranged on the side, close to the driving circuit layer, of the first substrate, the driving circuit layer is arranged on the side, away from the first substrate, of the touch electrode layer, and the pixel electrode layeris arranged on the side, away from the first substrate, of the driving circuit layer; the second base plate is arranged opposite to the first base plate and comprises a second substrate and a common electrode layer; and the liquid crystal layer is formed between the first substrate and the second substrate by filling. Integration of a vertical orientation display panel and a self-capacitance touchscheme is realized; compared with an externally-hanging touch display panel, tempered protective glass and a laminating process are omitted, and the cost is saved; compared with a traditional embedded touch display panel, the limitation that the electrodes can only adopt a common electrode reuse mode is broken through; and the sensitivity is higher, and the method is more suitable for large-sizecommercial products.

Description

technical field [0001] The present application relates to the display field, in particular to a self-capacitive touch display panel and a driving method thereof. Background technique [0002] As a kind of biometric technology, fingerprint recognition technology has the characteristics of universality, uniqueness, security and collectability. It has been widely used in smart phones and other products. With the rise of full screen technology. [0003] However, most of the existing touch displays are in the form of plug-in, that is, a touch panel is pasted on the display panel. This method will increase the thickness of the screen and terminal, increase the module process and cost, and affect the user experience. [0004] Therefore, existing touch displays have defects and need to be improved. Contents of the invention [0005] The invention provides a self-capacitive touch display panel and a driving method thereof, so as to improve the defects existing in the existing tou...
