Title: Innovations of Sang Tae Lee in Liquid Crystal Display Technology
Introduction
Sang Tae Lee is a notable inventor based in Kumi-shi, South Korea. He has made significant contributions to the field of liquid crystal display (LCD) technology. With a total of 3 patents to his name, his work focuses on improving the performance and quality of LCDs.
Latest Patents
One of his latest patents is an "Apparatus and method for compensating gamma voltage of liquid crystal display." This invention involves a gamma voltage compensating apparatus that enhances the charge characteristics of a pixel. The apparatus includes a pre-charge voltage generator that produces a pre-charge voltage, allowing the gamma voltage to exceed a target voltage within a specific time interval during each horizontal period. A gamma voltage generator then combines this pre-charge voltage with a predetermined reference voltage, adjusting the level based on the image signal voltage. This innovation aims to prevent voltage differences between horizontal and vertical pixels, thereby improving display quality.
Another significant patent by Sang Tae Lee is the "Apparatus and method for correcting gamma voltage and video data in liquid crystal display." This invention enhances the display quality of LCDs by storing gamma data for controlling gamma voltage across at least two modes. The gamma data is accessed based on the selected mode, generating multiple gamma voltages with varying levels. Additionally, a lookup table is utilized to correct the color temperature characteristic of an input image, ensuring that the data lines are driven by the appropriate color temperature correction data.
