Self-contained touch display panel

Abstract

The embodiment of the invention discloses a self-capacitance touch display panel. The self-capacitance touch display panel comprises a display panel and a touch layer arranged on the display panel, the touch control layer comprises a touch control layer and a protective layer, wherein the touch lead layer is arranged on the display panel and provided with a plurality of touch leads, the first insulating layer is arranged on the touch lead layer, the touch shielding layer is arranged on the first insulating layer, and the second insulating layer is arranged on the touch shielding layer. The touch sensing layer is arranged on the second insulating layer and is provided with sensing patterns arranged in an array; wherein the sensing pattern of the touch sensing layer is correspondingly communicated with the touch lead of the touch lead layer through the touch shielding layer. According to the embodiment of the invention, the touch shielding layer is additionally arranged between the touchsensing layer and the touch lead layer, so that the sizes of touch patterns at the near end and the far end of the touch are the same, the touch performance of the near end and the far end is consistent, and the touch performance of the flexible touch display panel is improved.

Description

technical field [0001] The invention relates to the field of display technology, in particular to a self-capacitive touch display panel. Background technique [0002] With the development of the times, mobile phones, as important electronic products, affect people's life and work, and their touch display is indispensable as an important part of human-computer interaction. Flexible touch display has gradually become the mainstream development direction in the future. In the control display, it is necessary to make the touch display panel thinner so as to achieve a smaller bending radius. [0003] In the prior art, in the flexible display touch display, the panel usually adopts AMOLED, and the touch solution in AMOLED is a mutual capacitive touch solution. Transparent PI (polyimide) material or flexible glass and its combination, the thickness of the cover plate is 50um~200um, the design of the thin cover plate causes the problem of multi-point floating reporting in mutual ca...

Problems solved by technology

[0003] In the prior art, in the flexible display touch display, the panel usually adopts AMOLED, and the touch solution in AMOLED is a mutual capacitive touch solution. Transparent PI (polyimide) material or flexible glass and its combination, the thickness of the cover plate is 50um~200um, the design of the thin cover plate causes the problem of multi-point floating reporting in mutual capacitance touch, which makes the user touch experience poor ; Choosing self-capacity in the AMOLED oncell touch solution can effectively solve the problem of multi-point floating touch, but there are problems in the design of self-capacity touch: figure 1 As shown, in the self-capacitive touch design, the number of leads in the near-end touch pattern close to the FPC (flexible circuit board) end is too large, which causes the influence of the touch blind area

[0004] Therefore, there is an urgent need to seek a self-capacitive touch display panel to solve the technical problem of poor near-end touch performance in the prior art
