  • GOA circuit and liquid crystal display panel
    Patent number: 11158274
    Abstract: The present disclosure provides a gate driver on array (GOA) circuit and a liquid crystal display panel. A blocking unit is disposed in each stages of GOA units. When a first node is at a high voltage potential and a stage signal is also at a high voltage potential, a first control signal and a second control signal are at a low voltage potential and both gates of a twelfth thin-film transistor (TFT) and a thirteenth TFT are at the low voltage potential so that gate-source voltage differences between the twelfth TFT and the thirteenth TFT are large enough to properly turn off the twelfth TFT and the thirteenth TFT. Thus, current leakage of the first node is prevented.

  • Parallel pipelines for computing backlight illumination fields in high dynamic range display devices
    Patent number: 11074871
    Abstract: A display controller generates a backlight illumination field (BLIF) based on a coarse point-spread function (PSF) and a correction PSF. The display controller samples the coarse PSF to accumulate light contributions from a larger neighborhood of LEDs around a given LCD pixel. The display controller samples the correction PSF to generate correction factors for a smaller neighborhood of LEDs around the given LCD pixel. The display controller interpolates samples drawn from the coarse PSF and samples drawn from the correction PSF and then combines the interpolated samples to generate a full resolution BLIF.
