Abstract

The present invention provides a touch display device, which comprises: an organic light emitting diode display panel including a support pillar and a cathode, wherein a part of the cathode is formedon the support pillar; and a touch layer positioned on one side of the organic light emitting diode display panel, wherein the touch layer comprises an insulating layer and a first conducting layer, aprotrusion is arranged on the insulating layer, part of the first conducting layer is located on the side, away from the cathode, of the protrusion, and the orthographic projection of the protrusionon the touch display device at least partially coincides with the orthographic projection of the support pillar on the touch display device. According to the touch display device, the protrusion is arranged on the insulating layer of the touch layer, so that the distance between the cathode on the support pillar and the first conducting layer on one side of the protrusion on the insulating layer is increased, so that the parasitic capacitance between the first conducting layer arranged corresponding to the support pillar and the cathode on the support pillar is reduced, and the touch reportingrate of the touch display device is increased.

Description

technical field [0001] The present application relates to the technical field of touch display, in particular to a touch display device. Background technique [0002] Flexible organic light-emitting diode (Organic Light-Emitting Diode, OLED) display has the advantages of active light emission, large viewing angle, wide color gamut, high brightness, fast response, low power consumption, and structural bendability. Flexible organic light-emitting diode display It is becoming more and more popular in the market, gradually replacing liquid crystal displays and becoming the mainstream of display technology. [0003] Flexible organic light-emitting diode displays are divided into top-emitting and bottom-emitting types according to their light-emitting positions. At present, the top-emission organic light emitting diode display is the mainstream of the mass production technology of the organic light emitting diode display. Such as figure 1 , which is a schematic diagram of a con...
