Title: Il-Kwon Chang: Innovator in Display Technology
Introduction
Il-Kwon Chang is a prominent inventor based in Gimpo-si, South Korea, known for his significant contributions to display technology. With a remarkable portfolio of 7 patents, he has made substantial advancements in optimizing data transfer rates and power consumption in display devices.
Latest Patents
One of his latest inventions is the patent titled "Driving multiple sub-pixels from single gray scale data." This innovative technology allows for the generation of source line voltages in a display device. By receiving gray scale data at a source driver for a first sub-pixel, the source driver can create a first source line voltage for that sub-pixel, as well as a second source line voltage for another sub-pixel. This approach minimizes the data transfer rate and/or data buses, leading to reduced power consumption and electromagnetic interference (EMI).
Another notable patent from Il-Kwon Chang is the "Digital/analog converting driver and method." This invention features a digital/analog converting driver that transforms digital data with M+N bits into an analog voltage. The driver comprises a first converting unit, a second converting unit, and an analog voltage outputting unit. The first unit converts successive M bits into a first voltage, while the second unit converts successive N bits into a second voltage. The combination of these voltages results in an output that varies across a specific range, enhancing the efficiency of analog output generation.
