Title: Innovations of Chuanzhen Liu
Introduction
Chuanzhen Liu is a notable inventor based in Beijing, China. He has made significant contributions to the field of organic light-emitting diodes (OLEDs) and thin-film transistor liquid crystal displays (TFT-LCDs). With a total of 2 patents, his work has advanced the technology used in display systems.
Latest Patents
One of his latest patents is for perforated-electrode organic light-emitting diodes. This invention utilizes a π-conjugated polymer emissive layer (MEH-PPV) sandwiched between two semitransparent electrodes. The preferred embodiment employs an optically thin gold film anode, while the cathode features an optically thick aluminum film with a patterned periodic subwavelength 2D hole array. This design showed an anomalous transmission in the spectral range of the polymer photoluminescence band, resulting in a seven-fold electroluminescence efficiency enhancement compared to a control device with an unperforated aluminum electrode.
Another significant patent involves an array substrate of TFT-LCD and a method for manufacturing the same. This invention includes gate lines, data lines, pixel electrodes, and thin-film transistors (TFTs) formed on a substrate. A grid graph is formed on each pixel electrode, allowing them to function as built-in polarizers that convert natural light into linear polarized light. The manufacturing method reduces production costs and thickness while enhancing power utilization efficiency.
