Latest Patents

One of his latest patents is titled "Methods and apparatus of dynamic backlight control." This invention involves a method for adjusting image intensity to compensate for backlight dimming. The method estimates distortion of an image based on different mapping index values selected from the intensity levels of the image. The estimated distortion represents factors such as the quantity of pixels exceeding a mapping index value and the extent to which pixel intensity exceeds the corresponding mapping index value. Additionally, the method includes selecting from various schemes to minimize the estimated distortion.

Another significant patent is "Driving system and method for electroluminescence displays." This invention describes a driving system for electroluminescence displays that features a matrix of electroluminescence elements arranged in rows and columns. The system includes a control circuit that discharges each anode line to a column equalization bus (CEB). The process allows for charge-sharing with un-activated anode lines, ensuring efficient image display while maintaining voltage levels to prevent inadvertent activation of de-activated elements.
