Title: Jemm Y Liang: Innovator in Low Power LCD Technology
Introduction
Jemm Y Liang is a prominent inventor based in San Jose, CA, known for his significant contributions to low power liquid crystal display (LCD) technology. With a total of 8 patents to his name, Liang has made strides in enhancing the efficiency and performance of LCDs, making them more sustainable and user-friendly.
Latest Patents
Liang's latest patents include innovative designs aimed at reducing power consumption in LCDs. One notable patent is for a "Low power LCD with gray shade driving scheme." This invention allows for different time periods of frame display in passive liquid crystal displays, achieving gray scale while minimizing power usage. The voltage pulses applied to the column electrodes maintain substantially constant values during scanning periods, which helps in reducing power consumption. Additionally, the display lines are organized into odd and even fields in an interlaced configuration to suppress flicker and further decrease power consumption by lowering the frame rate.
Another significant patent is the "Low power LCD driving scheme employing two or more power supplies." This design utilizes two separate power supplies to generate electrical potentials for driving the row and column electrodes of LCDs. By incorporating energy storage devices, the system can charge in one phase and generate the necessary potentials in another, allowing for a much smaller voltage range compared to conventional driving schemes. This innovation drastically reduces power consumption while maintaining a comparable voltage dynamic range.
