Embodiment approach

[0049] According to one embodiment, as Figure 4 As shown, the OLED bottom electrode 302 includes a bottom transparent conductive layer 302a, a top transparent conductive layer 302c, and a reflective layer 302b located between the bottom transparent conductive layer 302a and the top transparent conductive layer 302c. The touch sensing electrodes 206 can be located on the same layer as the bottom transparent conductive layer 302a. The touch sensing electrode 206 can be formed of the same material as the bottom transparent conductive layer 302a. According to an exemplary embodiment, the touch sensing electrodes 206 may be formed simultaneously with the bottom transparent conductive layer 302 a during the process of forming the bottom transparent conductive layer 302 a. According to an example embodiment, the lower electrode 302 may have ITO / Ag / ITO, that is, the bottom transparent conductive layer 302a and the top transparent conductive layer 302c are formed of ITO, and the refl...

Abstract

The invention relates to an organic light emitting diode touch control display panel. The display panel comprises a thin film transistor array substrate, an OLED element and a touch control array. The touch control array comprises a first touch control line, a second touch control line and a touch control sensing electrode, wherein the first touch control line is extended along a first direction and is disposed in the same layer with a gate line; the second touch control line is extended along a second direction, is intersected with the first touch control line and is disposed in the same layer with a data line; and the touch control sensing electrode is disposed in the same layer with a lower electrode of the OLED element, is spaced from the lower electrode and is electrically connected with a touch control sensing electrode line via a contact hole in a planarization layer. The organic light emitting diode touch control display panel has a good display effect and / or good touch control detection precision.

Description

technical field [0001] The present disclosure relates to an organic light emitting diode display panel, in particular to a capacitive in-cell organic light emitting diode touch display panel and a manufacturing method thereof. Background technique [0002] Active Matrix Organic Light Emitting Diode (AMOLED) is a new generation of display technology, with self-illumination, wide viewing angle, high contrast, low power consumption, high response speed, high resolution, full color, thin, etc. advantage. AMOLED is expected to become one of the mainstream display technologies in the future. [0003] Currently, touch display panels are widely deployed in various electronic devices such as mobile phones and tablet computers, and the devices are controlled through touch sensing. OLED touch display panels that integrate touch components with OLED display panels have begun to enter the market. [0004] Integrating touch components into OLED panels generally adopts in-cell, on-cell,...
