AI Technical Summary

Technical Problem

Current LED display panels reflect ambient light easily due to high reflectivity of metallic signal lines, leading to poor performance and high power consumption.

Method used

Incorporate a light absorption layer that overlaps with the driver layer on the substrate, featuring through-holes for conductive pads, and optionally includes insulating layers to protect and enhance light absorption, reducing reflectivity and power consumption.

Benefits of technology

Reduces reflectivity and power consumption by absorbing ambient light effectively, allowing higher light transmittance and brightness without increasing driver current.

Abstract

The present application describes a display panel and a display device in the field of display technology. The display panel comprises a substrate, a driver layer, a light-absorbing layer, and several luminaires. An orthographic projection of the light-absorbing layer onto the substrate overlaps with an orthographic projection of the driver layer onto the substrate. This allows the ambient light directed onto the display panel to be absorbed by the light-absorbing layer, resulting in less reflection from the driver layer. This reduces the reflectivity of the display panel to ambient light. The light-absorbing layer in the display panel further reduces the reflectivity of the display panel to ambient light.Therefore, the light transmittance of an auxiliary light absorption layer located on the side of the multiple light units facing away from the substrate can be increased accordingly, so that the light absorption rate of the auxiliary light absorption layer is low, thereby reducing the absorption of light emitted by the light units and effectively reducing the power consumption of the display panel.
