Problems solved by technology

[0004] However, when the surface of the above-mentioned touch display panel is under pressure, the distance between the color filter substrate and the array substrate changes little. The change in the distance between the lower electrodes on the array substrate is also small, so that the capacitance change between the upper electrode and the lower electrode is small, so that the pressure signal is often unable to be detected, and the pressure detection sensitivity is low

Abstract

An embodiment of the invention discloses a touch display panel. The touch display panel comprises a supporting structure, a first electrode, a second electrode and a third electrode, wherein the supporting structure is located on one side, facing to a first substrate, of a second substrate; the supporting structure includes a first supporting structure and a second supporting structure; the first electrode covers the first supporting structure and the second supporting structure and is located on one side, facing to the first substrate, of the second substrate; the second electrode and the third electrode are located on one side, facing to the second substrate, of the first substrate; orthographic projection, on the first substrate, of the second electrode and orthographic projection, on the first substrate, of the third electrode have a first overlapping area; in the first overlapping area, the second electrode and the third electrode are insulated from each other through a first insulation layer; and the distance between the first electrode located on one side, close to the first substrate, of the first supporting structure and the second electrode is not equal to the distance between the first electrode located on one side, close to the first substrate, of the second supporting structure and the third electrode. Therefore, the pressure detection sensitivity of the touch display panel is improved.

Description

technical field [0001] The present invention relates to the field of touch technology, in particular to a touch display panel. Background technique [0002] With the development of display technology, more and more display panels with touch function are widely used in people's daily life and work, which brings great convenience to people's daily life and work, and has become an indispensable essential tool. [0003] The touch display panel in the prior art is usually provided with an upper electrode and a lower electrode on the oppositely arranged color filter substrate and array substrate respectively, and when the surface of the touch display panel is under pressure, the The capacitance change between the upper electrode on the upper surface and the lower electrode arranged on the array substrate is realized to realize pressure detection. [0004] However, when the surface of the above-mentioned touch display panel is under pressure, the distance between the color filter...
