Problems solved by technology

As a result, when a person's finger or conductive stylus touches the display panel, the current flowing through the OLEDs on the display panel may be erratic or uneven
In addition, conventional ITO electrodes can have high resistivity and slow down the response to touch action

Abstract

The invention provides an array substrate for a display panel of an organic light emitting diode. The array substrate comprises a substrate, a thin film transistor layer, an anode layer and a cathode layer. The thin film transistor layer comprises a plurality of thin film transistor. Each thin film transistor comprises a source electrode and a leakage electrode. The anode layer comprises a plurality of anode electrodes used for applying an anode voltage. Each anode electrode is connected to the source electrode or the leakage electrode of the corresponding thin film transistor. The cathode layer comprises a plurality of mutually insulated contact electrodes used for time sharing multiplex. A cathode voltage and a touch induction voltage are applied on the plurality of contact electrodes.

Description

technical field [0001] The present invention relates to the field of display technology, in particular to an array substrate for a light emitting diode display panel, a display panel, and a display device. Background technique [0002] With the development of organic light-emitting diode (OLED) display technology, organic light-emitting diode display panels have been widely used in electronic devices, such as mobile phones, tablet computers, and flat-screen TVs. Compared to conventional liquid crystal display (LCD) devices, OLED display devices do not require a backlight. Organic light emitting diode display devices are also relatively thin and light, and generally have the advantages of wide viewing angles and short response times. In addition, organic light emitting diode display devices generally have higher luminous efficiency. [0003] Typically, in organic light emitting diode devices, a conductive organic light emitting layer is positioned between two electrode laye...
