Abstract

The embodiments of the invention provide an OLED touch control display panel and a touch control display device and relate to the technical field of display. There is no need to use a multi-layer thin film outside-embedded touch control structure and the structure of the OLED touch control display panel is simplified. The OLED touch control display panel comprises a TFF back plate and a cathode layer arranged on the TFT back plate. The cathode layer comprises a plurality of touch control leads insulated from each other and a plurality of self-capacitance electrodes which are arranged in a rectangular form and insulated from each other. The touch control leads extend to a non-display area of the OLED touch control display panel. Each touch control lead is connected with one self-capacitance electrode and the resistance values of multiple touch control leads connected to the self-capacitance electrodes in the same row are the same. The OLED touch control display panel is used for display and touch control.

Description

technical field [0001] The present invention relates to the field of display technology, in particular to an OLED touch display panel and a touch display device. Background technique [0002] AMOLED (Active Matrix Organic Light Emitting Diode Display, active matrix drive organic light emitting diode display device) has the advantages of low manufacturing cost, high response speed, power saving, DC drive for portable devices, and wide operating temperature range. It is expected to become the next generation of new flat-panel displays to replace LCD (Liquid Crystal Display, Liquid Crystal Display). In particular, flexible AMOLED is attracting more and more attention from the market because of its advantages of being thin and light, bendable or foldable, and capable of changing shape arbitrarily. [0003] For AMOLED, it is usually necessary to set up an encapsulation cover plate to achieve the function of blocking water and oxygen. The above-mentioned packaging cover plate ma...
