Title: Innovations of Ping-Hsien Chen
Introduction
Ping-Hsien Chen is a notable inventor based in Pingtung County, Taiwan. He has made significant contributions to the field of voltage regulation and display technology. With a total of 3 patents to his name, Chen's work has had a considerable impact on the industry.
Latest Patents
One of his latest patents is a voltage regulation method. This method includes several steps, such as providing a plurality of fixed voltages to a gray-level resistor string. It divides a plurality of gray-level voltages and the fixed voltages into a first voltage group and a second voltage group based on the signal-to-noise ratios of the gray-level values. The method determines whether the regulated fixed voltage is used to regulate a gray-level voltage corresponding to a low gray-level value according to different voltage groups. Additionally, it assesses whether the fixed voltage needs to be regulated again by measuring the luminance value of a gray-level voltage with a higher signal-to-noise ratio.
Another significant patent is an apparatus to select gamma reference voltage and the method of the same. This invention provides a method for selecting a gamma reference voltage, which is used to switch the picture to a first gray scale. The second gray scale and its luminance of various regions of a liquid crystal display panel are determined by a sensor, and the gamma voltage corresponding to the second gray scale is stored in a bank for output. The bank signal is then input to a reference voltage.
