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.
