Patent ID: 8901549

Claim:
An organic light emitting diode touch display panel, comprising: a substrate, having a plurality of pixel regions and a peripheral region, wherein the pixel regions are arranged in an array formation, and the peripheral region is disposed at a side of the pixel regions, wherein each pixel region has at least three sub-pixel regions and a sensing region disposed at a side of the sub-pixel regions; a plurality of first electrodes, disposed on the substrate in the sub-pixel regions respectively; a plurality of second electrodes, and at least one of the second electrodes being disposed on the substrate in each sensing region, wherein the at least one of the second electrodes in each pixel region and the first electrodes in each pixel region are arranged along a first direction in sequence in the pixel regions of each column; a plurality of light emitting layers, and each light emitting layer being disposed on each first electrode; a plurality of dielectric layers, and each dielectric layer being disposed on each second electrode; a plurality of first electrode stripes, and each first electrode stripe being disposed on the light emitting layers in the pixel regions of each row; a plurality of second electrode stripes, and each second electrode stripe being disposed on the dielectric layers in the pixel regions of each row, wherein each first electrode, each light emitting layer and each first electrode stripe form an organic light emitting diode, and each second electrode, each dielectric layer and each second electrode stripe form a touch sensing capacitor; and a plurality of rib stripes, disposed on the substrate sequentially arranged along the first direction, wherein each rib stripe is disposed between each first electrode stripe and each second electrode stripe adjacent to each other, and each first electrode stripe and each second electrode stripe adjacent to each other are electrically insulated from each other by each rib stripe, wherein each of the light emitting layers and each of the dielectric layers are formed with a same layer of organic light emitting material, and a reverse bias is applied to each touch sensing capacitor to avoid each touch sensing capacitor generating light.
