Latest Patents

Among his latest innovations, Ki-Hyun Pyun has developed a display apparatus and a method of driving the same. This display apparatus includes a display panel, a memory, a bit-data converter, a switch, and a gate driver. The display panel consists of pixels, each connected to data lines and gate lines. The memory stores multiple image data corresponding to a frame period. The bit-data converter determines a plurality of bit data, which corresponds to the degree of change between adjacent image data. It obtains a sum of the bit data and outputs this sum as a total count bit data value. The switch then outputs a first pulse control signal based on this total count bit data value. The gate driver generates a gate signal based on the first pulse control signal and outputs it to one of the gate lines.

Another notable patent is for a liquid crystal display device and its driving method. This device includes a display panel with data lines and gate lines that intersect. A gate driver sequentially applies a scan signal to the gate lines, while a data driver applies data voltages corresponding to each gate line to the data lines. A timing controller manages the gate driver and data driver, ensuring synchronized operation. Additionally, a power source supply circuit provides both positive and negative power sources, while a common voltage feedback circuit outputs an amplified feedback signal based on the voltage level difference between the reference voltage and the common voltage.
