Latest Patents

One of Tian-Hau Chen's latest patents is a source driver for image scrolling. This invention comprises a frame memory, a first line buffer, and a second line buffer. The frame memory stores bits of pixel values of an image. The first line buffer sequentially latches the bits of the pixel values from the frame memory with a first address index. The second line buffer then sequentially latches the bits of the pixel values from the first line buffer with a second address index, which is different from the first address index, and writes the bits of the pixel values back to the frame memory, allowing the image to be scrolled. Additionally, the invention provides a method for refreshing the frame memory in a source driver.

Another significant patent is a power switch device. This device is designed to receive multiple input voltages and output a switch voltage. It comprises a first switching unit, a second switching unit, and a self-bias unit. The power switching device outputs a switch voltage based on the outputs of the first and second switching units. The self-bias unit provides a reference voltage to the second switching unit. The first switching unit outputs a first input voltage as the switch voltage according to a first enable signal, while the second switching unit outputs a second input voltage as the switch voltage based on the reference voltage and a second enable signal.
