OLED pixel structure, OLED display screen and electronic device

Abstract

The invention provides an OLED pixel structure. The OLED pixel structure includes a substrate, and a first electrode, a pixel layer and a second electrode sequentially laminated on the substrate, wherein the pixel layer includes multiple pixel points arranged in an array mode, a gap is formed between two adjacent pixel points, the first electrode and the second electrode are set on the corresponding gaps in a hollow-out mode, an isolation column is further included, the isolation column is partially accommodated in the gap, the isolation column has a first end surface and a second end surfaceopposite to the first end surface, the first end surface faces towards the substrate, the second end surface faces away from the substrate, and the isolation column is used conducting a light signal and allowing the light signal to be transmitted into one of the first end surface and the second end surface and to be transmitted out from the other end surface. The invention further provides an OLEDdisplay screen and an electronic device. The OLED pixel structure is advantaged in that the light signal is conducted by the isolation column, the light signal is allowed to be transmitted into one of the first end surface and the second end surface and to be transmitted out from the other end surface, signal interference is avoided, and the light signal to noise ratio is effectively improved.

Description

technical field [0001] The present application relates to the field of OLED pixel structure display, in particular to an OLED pixel structure, an OLED display screen and electronic equipment. Background technique [0002] One of the difficulties in the application of off-screen light detection technologies such as under-screen light sensing is that the light sensor is located under the OLED display, and the light signal needs to pass through the gap between the R / G / B pixels of the OLED screen and the isolation column to be detected by the light. The sensor receives. However, only a very small amount of light signals can be received regardless of visible light or infrared light bands; moreover, when the pixels of the OLED display screen emit light, part of the light passes through R / G / B pixels through scattering and reflection. The gap between the point and the isolation post leaks to the light sensor, resulting in a decrease in the optical signal-to-noise ratio and affectin...
