Title
(EN) Touch display device
(ZH) 触控显示装置
Abstract
(EN) 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.
(ZH) 本申请提供一种触控显示装置,触控显示装置包括:有机发光二极管显示面板,有机发光二极管显示面板包括支撑柱以及阴极,部分阴极形成于支撑柱上;触控层,触控层位于有机发光二极管显示面板的一侧,触控层包括绝缘层以及第一导电层,绝缘层上设置有凸起,部分第一导电层位于凸起远离阴极的一侧,凸起在触控显示装置上的正投影与支撑柱在触控显示装置上的正投影至少部分重合。通过在触控层的绝缘层上设置凸起,以增加支撑柱上的阴极与绝缘层上的凸起一侧的第一导电层之间的间距,从而减小对应支撑柱设置的第一导电层与支撑柱上的阴极之间的寄生电容,提高触控显示装置的触控报点率。
