Introduction

Po-Hsien Tsai is a notable inventor based in Tainan County, Taiwan. He has made significant contributions to the field of flat display technology, holding a total of 2 patents. His work focuses on enhancing the performance and efficiency of liquid crystal displays (LCDs).

Latest Patents

One of his latest patents is titled "Flat display and timing controller thereof for neutralizing charges in liquid crystal capacitors upon shut down." This invention involves a timing controller designed for flat displays, which includes a voltage detecting circuit, a clock generator, and two multiplexers. The voltage detecting circuit monitors variations in operating voltage and generates a reset signal. The clock generator produces a start signal and a first clock signal, while the multiplexers manage the signals based on the reset signal. The second clock signal operates at a higher frequency than the first, optimizing the display's performance.

Another significant patent is "Apparatus and method of charge sharing in LCD." This method addresses charge sharing between source lines in a pixel array. It involves grouping source lines into pairs and implementing charge sharing based on the data polarities of scanned rows. The method estimates energy driving the source lines and only executes charge sharing when it is beneficial, thus improving energy efficiency.
