Title: Yongai Zhang: Innovator in nLED Technology

Introduction

Yongai Zhang is a prominent inventor based in Fujian, China. He has made significant contributions to the field of light-emitting display technology, holding a total of 8 patents. His innovative work focuses on non-direct electrical contact methods for nLED light-emitting devices, which have the potential to revolutionize display technology.

Latest Patents

One of his latest patents is a non-direct electrical contact orientation ordered nLED light-emitting display device. This device comprises an upper drive electrode substrate, an upper drive electrode, an nLED grain sheet, a lower drive electrode, and a lower drive electrode substrate arranged sequentially. It also includes an AC drive control module connected to the upper and lower drive electrodes. The nLED grain sheet consists of multiple nLED grains arranged in order, allowing for a light-emitting layer that is parallel to the electrode substrates and perpendicular to the electric field. This design enables the nLED grains to light up through electromagnetic coupling, effectively reducing process costs by omitting the transfer of a greater number of μLEDs and nLEDs.

Another notable patent is a light-emitting display device based on special-shaped nLED grains. This device features an upper drive electrode substrate, an upper drive electrode, special-shaped nLED grains, a lower drive electrode, and a lower drive electrode substrate. The special-shaped nLED grains each have a non-planar luminous layer, which enhances electrical coupling efficiency and luminous efficiency when an AC drive signal is applied.
