Title: Innovations by Hyunchul Kim
Introduction
Hyunchul Kim is a prominent inventor based in San Jose, California. He has made significant contributions to the field of display technology, holding a total of 12 patents. His work focuses on enhancing the performance and longevity of display systems, particularly in addressing issues related to frequency compensation and burn-in effects.
Latest Patents
One of Hyunchul Kim's latest patents is centered on frequency compensation for displays. This patent describes techniques and apparatuses that perform frequency compensation by measuring the uniformity of multiple regions of a display at a reference frequency. The display is then driven at a second frequency, allowing for a second uniformity measurement. The differences between the first and second uniformity measurements are utilized to generate a compensation mask. This process involves using XYZ domain data from the measurements to create a color model characterization, which converts the data into RGB format when the display operates at the second frequency.
Another notable patent addresses burn-in compensation for displays. This method minimizes or eliminates burn-in effects in OLED displays that have varying pixel densities. The OLED display is divided into zones, each containing one or more pixels. A burn-in factor is computed for these zones, and adjustments are made to ensure that pixels in different zones radiate similar light levels. This approach helps to create a transition region between areas, reducing light artifacts after burn-in compensation.
