Introduction

Jeong-seok Chae is a prominent inventor based in Suwon, South Korea. He has made significant contributions to the field of display technology, holding a total of 2 patents. His work focuses on enhancing the efficiency and functionality of display driving integrated circuits.

Latest Patents

One of his latest patents is a display driving integrated circuit and method. This innovation is designed to reduce the number of transmission lines required for transmitting gray-scale data from a memory. The display driving IC receives M-bit gray-scale data to represent the gray scale of one pixel and drives a panel that includes multiple pixels. The integrated circuit features a memory that stores gray-scale data for the plurality of pixels, a source driver that transmits the gray-scale data to the panel, and at least one multiplexer that transmits the M-bit gray-scale data through L transmission lines, where L is less than M.

Another notable patent is a voltage reference generator with flexible control of voltage. This device includes a current source that generates a source current in response to a control voltage and a current sink that conducts the source current to produce a reference voltage. Additionally, a switch block is configurable to determine the level of the source current conducted through the current sink. The reference current generator employs transistors operating in weak inversion with an active load coupled to one of the transistors.
