With a total of three patents to his name, Yu's work aims to enhance the quality and longevity of OLED displays, making them more efficient and effective for modern applications.

Latest Patents

Among his latest innovations, Yu has developed a groundbreaking patent for an organic light emitting diode display and driving method. This invention focuses on changing data corresponding to image properties to prevent the deterioration of an OLED device's lifespan while enhancing picture quality. The method involves analyzing the digital data of an input image to assess cumulative density distribution for various grayscale ranges destined for display. In cases where high grayscale data is predominant, the patent describes a technique to lower the tilt of the gamma curve. Conversely, if a specific grayscale data range is dominant, the method raises the gamma curve's tilt, allowing for improved image representation. Furthermore, this modulated digital data is then converted into an analog signal, paving the way for superior display results.

Additionally, Yu holds a patent for an organic light emitting diode display device along with its driving method. This invention includes a data driver that generates reference data voltages proportional to the grayscale levels of digital data supplied from the timing controller. The data driver effectively compensates for these data voltages based on feedback from the pixels, ensuring accurate and improved display performance.
