Abstract

The invention discloses a capacitive touch display panel, a display device, a control device and a control method, which are used for solving the display and touch function of a display panel without additionally adding a touch panel, simplifying the structure of the capacitive touch display panel and increasing the light transmissivity. The capacitive touch display panel provided by the embodiment of the invention comprises an array substrate, a color film substrate and a liquid crystal layer which is positioned between the array substrate and the color film substrate, wherein the array substrate comprises a substrate, a polarizer, a BM (Black Matrix) and a TFT (Thin Film Transistor) functional unit, the array substrate is positioned at a light outlet side of the capacitive touch display panel, the color film substrate is positioned at a light inlet side of the capacitive touch display panel, the TET functional unit comprises a grid line, a data line and a TFT, the BM corresponds to the TFT, and projections of a grid electrode, a source electrode and a drain electrode of the TFT in a substrate direction are all projected in the BM.

Description

technical field [0001] The present invention relates to the field of liquid crystal display technology, in particular to a capacitive touch display panel, a display device, a control device and a method. Background technique [0002] With the rapid development of display technology, touch screen panels (Touch Screen Panels) have gradually spread throughout people's lives. At present, the structure of the touch screen is generally to install a layer of touch panel on the light-emitting side of the display panel, and then bond them together to form a touch-enabled LCD display. The production cost is high, the light transmittance is low, and the module is thick. shortcoming. [0003] Such as figure 1 As shown, the LCD display panel structure in the prior art includes from top to bottom: protective layer 10, touch panel 40, upper polarizer 201, shielding ITO 70, color filter layer 60, upper alignment layer 401, liquid crystal material 50, lower The alignment layer 402 , the T...
