Problems solved by technology

[0004] Based on the above structure, the way to achieve capacitive touch is usually to attach the touch function unit on the upper polarizer, which needs to be bonded to a glass with a touch sensor electrode, which is very costly, and because of the additional bonding process, The yield rate is reduced, and the thickness greatly affects the transmittance

Abstract

The invention discloses an embedded type capacitor touch display panel, a display device, a control device and a method so that display and touch functions of the display panel can be achieved without adding a touch panel, the structure of the embedded type capacitor touch panel is simplified, and the light transmittance is improved. An embodiment of the invention discloses the embedded type capacitor touch-control display panel which comprises an opposite substrate, an array substrate and a liquid crystal layer, wherein the array substrate comprises a grid line and a data line which are crosswise arranged as well as a public transparent electrode layer; the array substrate further comprises a touch drive electrode which is located on the public transparent electrode layer and extends in a first direction as well as a touch induction electrode which is separated from the touch drive electrode by an insulating layer and extends in a second direction; the first direction is perpendicular to the second direction; and a public voltage signal and a touch drive signal are applied onto the touch drive electrode in a time-sharing manner.

Description

technical field [0001] The present invention relates to the field of liquid crystal technology, in particular to an embedded capacitive touch display panel, a display device, a control device and a method. Background technique [0002] The current Advanced Super Dimension Switch (ADS) LCD display module has a layer of ITO that acts as a shield on the outside of the color film CF. Protect the normal display of the LCD display module. Specifically, two layers of transparent electrodes are arranged on the array substrate of a traditional ADS type liquid crystal display, which form a multi-dimensional electric field through the electric field generated by the edge of the slit electrode in the same plane and the electric field generated between the slit electrode layer and the plate electrode layer. , so that all oriented liquid crystal molecules between the slit electrodes in the liquid crystal cell and directly above the electrodes can be rotated, thereby improving the working...
