Abstract

The invention discloses an organic light emitting diode display with a touch panel, comprising: a first substrate; an organic light emitting diode pixel unit located on the first substrate; a second substrate connected to the first substrate; a touch electrode located on the second substrate On the second substrate; a transparent insulating layer, formed on the touch electrode; a conductive layer, formed on the transparent insulating layer; a photosensor for detecting incident light generated by an external source, which is formed on the corresponding positions of the transparent insulating layer and the conductive layer. The through hole is located on the touch electrode; the photovoltaic material layer shields the surface of the light sensor on the side of the conductive layer facing the first substrate, and the photovoltaic material layer is coupled with the conductive layer. The photovoltaic material layer provided by the invention prevents the light emitted by the OLED from being detected by the light sensor, reduces the influence of the OLED light on the light sensor, and can absorb the light emitted by the OLED and convert it into electrical energy for self-power generation to realize self-charging of terminal products.

Description

technical field [0001] The invention relates to the field of organic light emitting diode displays, in particular to an organic light emitting diode display with a touch panel. Background technique [0002] For organic light-emitting diode (OLED) displays and their products, convenient and fast input can be performed through the touch screen, which becomes a new input method to replace existing input methods (such as keyboard and mouse). According to different implementation methods, touch screen can be divided into: resistive film method, capacitive method or light (infrared) method, etc.; the so-called resistive film method needs to realize input by pressing or touching and sliding the screen surface, which is easy to damage the display panel. [0003] The so-called optical method is provided by a light sensor to detect changes in incident light and generate a corresponding electrical signal, and detect the position based on the electrical signal. According to this method,...
