The embedded capacitive touch control display panel provided by the embodiment of the invention comprises a color film substrate, a liquid crystal material and an array substrate, wherein touch control induction electrodes are formed on the color film substrate; touch control drive electrodes are formed on the array substrate and are positioned between the array substrate and the liquid crystal material; and in a light transmission direction, projections of the touch control induction electrodes and the touch control drive electrodes all fall in a black matrix region of the color film substrate.

Description

technical field [0001] The present invention relates to the technical field of liquid crystal display, and 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 indium tin oxide ITO that acts as a shield outside the CF substrate of the color film, and its function is to prevent external signal sources from affecting the liquid crystal box. The internal liquid crystal driving electric field generates interference, thereby ensuring the normal display of the LCD display module. [0003] like figure 1 As shown, the basic structure of the ADS display device in the prior art includes from top to bottom: an upper polarizer 201, a shielded ITO30, an upper substrate 10, a black matrix 40, a color filter 50, an upper alignment layer 601, and a liquid crystal material 70. The lower alignment layer 602, the array subs...

Problems solved by technology

[0004] In the prior art, the solution for realizing touch control based on the above-mentioned ADS structure is generally to directly attach a touch function module on the outside of the ADS type liquid crystal box. The structure of the control electrode, which can realize the touch function independently, makes the cost of the existing touch display device very high, and because of the increase of the bonding process, the yield rate is reduced, and the thickness greatly affects the transmittance.
