OLED touch display panel
First Claim
1. An Organic Light Emitting Diode (OLED) touch display panel, comprising:
- a Thin Film Transistor (TFT) array substrate, comprising;
an active layer;
a gate insulation layer covering the active layer;
a gate line layer disposed on the gate insulation layer;
an inter-layer insulation layer covering the gate line layer and the gate insulation layer;
a data line layer disposed on the inter-layer insulation layer; and
a planarizing layer covering the data line layer;
wherein the gate line layer comprises a gate line and a gate electrode, the data line layer comprises a data line, a source electrode and a drain electrode, the gate line extends along a first direction, and the data line extends along a second direction intersecting with the first direction;
an OLED element formed on the TFT array substrate and comprising an upper electrode, a lower electrode and an organic layer between the upper electrode and the lower electrode, wherein the lower electrode is electrically connected with the source electrode or the drain electrode via a first contact hole in the planarizing layer;
a first touch line extending along the first direction and disposed in the same layer with the gate line;
a second touch line extending along the second direction, intersecting with the first touch line and disposed in the same layer with the data line; and
a touch sensing electrode disposed in the same layer with the lower electrode of the OLED element, spaced from the lower electrode and electrically connected with the second touch line via a second contact hole in the planarizing layer.

Abstract
The present disclosure provides an OLED touch display panel, including a TFT array substrate, an OLED element and a touch array. The touch array includes: a first touch line extending along a first direction and disposed in the same layer with a gate line; a second touch line extending along a second direction, intersecting with the first touch line and disposed in the same layer with a data line; and a touch sensing electrode disposed in the same layer with a lower electrode of the OLED element, spaced from the lower electrode and electrically connected with the second touch line via a contact hole in a planarizing layer. The OLED touch display panel has better display effect and/or accuracy of touch detection.
