Title: Haesang Park: Display Electronics Inventor
Introduction
Haesang Park is an inventor based in Goyang-si, South Korea. His work includes a patent for a digital-to-analog converter and a display driving circuit.
Latest Patents
Park’s listed patent, “Digital-to-Analog Converter and Display Driving Circuit Including the Same,” describes a converter that selects a gamma voltage corresponding to an image-data grayscale value and sends it to an output terminal. A slew rate controller connected to that terminal uses pull-up and pull-down transistors to control the output’s transition rate. The pull-up transistor connects the output to a high-potential voltage, while the pull-down transistor connects it to a low-potential voltage; each transistor receives its own slew rate control signal. Park is listed as an inventor on 1 patent.
