Embodiment Construction

[0038] This embodiment provides a touch display panel, as shown in 6, comprising a color filter substrate 1 and a thin film transistor array substrate 2 arranged oppositely, and a liquid crystal layer ( not shown).

[0039] Wherein, the lower surface of the color filter substrate 1 extends toward the direction of the thin film transistor array substrate (ie Figure 6 Extending downward in the center) is provided with a first columnar spacer 11 and a second columnar spacer 12, and the first columnar spacer is higher than the second columnar spacer, both of which are cross-sectional areas from top to bottom gradually Decreasing cylinder. A planarization layer 3 is provided on the upper surface of the thin film transistor array substrate 2 , and the planarization layer 3 is recessed toward the inside to form grooves 31 arranged at intervals. The first touch electrode lead 41 and the second touch electrode lead 42 are accommodated in the groove 31 respectively, and the upper sur...

Abstract

The invention provides a thin film transistor array substrate, a manufacturing method thereof, and a touch control display panel. The touch control display panel includes a color filter substrate, a thin film transistor array substrate mentioned above, and a liquid crystal layer and photo spacers located between the two substrates. When the color filter substrate combined with the thin film transistor array substrate face to face, the photo spacers is located therebetween. The thin film transistor array substrate has a planarization layer therein. The planarization layer is recessed to a plurality of grooves arranged at intervals. A plurality of touch control electrode lead wires are received in the plurality of grooves. Upper surfaces of the plurality of touch control electrode lead wires and an upper surface of the planarization layer are in a same plane.

Description

technical field [0001] The invention relates to the fields of touch technology and display technology, in particular to a thin film transistor array substrate, a preparation method thereof, and a touch display panel having the thin film transistor array substrate. Background technique [0002] With the development of touch technology and display technology, touch display panels have been widely used in smart electronic products such as smartphones and tablet computers, bringing more convenient experience for human-computer interaction. [0003] Currently, touch panels can be classified into Add on Mode Touch Panel, On Cell Touch Panel and In Cell Touch Panel according to their composition and structure. Among them, the embedded touch screen is to embed the touch electrodes of the touch screen inside the liquid crystal display panel, which can effectively reduce the overall thickness of the module and make it thinner and lighter, so it will definitely become the development o...
