Zhao Li

Title: Zhao Li’s Display Panel Innovations.

Introduction

Zhao Li is an inventor based in Wuhan, China. His work includes display panel and display device technologies, with a focus on the performance of light-emitting layers.

Latest Patents

Zhao Li’s listed patent portfolio includes 2 patents, both titled “Display Panel and Display Device.”

The first patent describes a light-emitting device layer containing n-type and p-type charge generation layers. It addresses operating-voltage stability by limiting the absolute difference between the layer’s initial operating voltage and its voltage after operation at a preset current density and temperature to no more than 1 V. The specified temperature is at least 50°C.

The second patent describes an organic light-emitting layer with doped and undoped regions, with the undoped region positioned between the doped region and the hole-blocking layer. During low-grayscale display, the exciton concentration distribution has two peaks: one in each region, with the peak in the undoped region lower than the peak in the doped region.

Career Highlights

Li is associated with Wuhan China Star Optoelectronics Semiconductor Display Technology Co., Ltd. The two listed inventions concern display panels and display devices, addressing voltage stability and exciton distribution in organic light-emitting layers.
