Latest Patents

One of his latest patents is titled "Method for driving liquid crystal display and non-transitory storage medium thereof." This invention discloses a method for driving thin film transistor liquid crystal displays (TFT-LCD) and includes a storage medium for storing a computer program representative of the method. The method utilizes a timing controller to send polarity control signals to a plurality of source drivers in a TFT-LCD panel, changing the polarity distribution of the liquid crystal molecules. It is characterized by dynamically changing the positions of polarity inversion to alleviate undercharging issues under high resolution and high frequency conditions. Additionally, it employs both polar and reverse polar driving signals to solve color shift problems in 'checker board' checking signals and provides a mechanism for addressing undercharging of the first horizontal line.

Another significant patent is "Device for decreasing the temperature from address IC of plasma display panel and the method thereof." This device is designed to dissipate heat from addressing integrated circuits (addressing ICs) of a plasma display panel. It utilizes a back plate with a greater surface area to dissipate heat directly from the addressing ICs. The embodiment of this device includes a heat-conducting sheet attached to the addressing ICs, which rapidly conducts heat to the back plate, thereby increasing the efficiency of heat dissipation without adding to the volume of the plasma display panel.
