US11638095B2	Method and apparatus for improving effective signal-to-noise ratio of analog to digital conversion for multi-band digital signal processing devices A method for improving the effective signal-to-noise ratio (“SNR”) of an analog to digital converter (“ADC”) for active loudspeakers uses the two available channels of a stereo ADC to separately process the low- and high-frequency components of an audio signal. Because the power spectral density of music approximates a pink noise spectrum, the high-frequency component of the signal has peak levels low enough to avoid exceeding the maximum ADC input level. The audio signal is analog high-pass filtered and the resulting high-frequency signal component is sent directly to a first ADC channel without attenuation. The remaining low-frequency component is attenuated and sent to a second ADC channel. The digital signals are processed, converted back to analog, amplified, and reproduced by loudspeaker drivers. Noise and distortion at low frequencies is less audible than higher frequencies, so the improved SNR at higher frequencies yields a significant practical improvement in audio fidelity.

US11638007B2	Codebook generation for cloud-based video applications Techniques are disclosed for the improvement of vector quantization (VQ) codebook generation. The improved codebooks may be used for compression in cloud-based video applications. VQ achieves compression by vectorizing input video streams, matching those vectors to codebook vector entries, and replacing them with indexes of the matched codebook vectors along with residual vectors to represent the difference between the input stream vector and the codebook vector.

US11636817B2	Liquid crystal device and electronic apparatus In a liquid crystal device, a first pixel area is provided in a pixel area of a first substrate, and a second pixel area is provided between the first pixel area and a seal material. The first pixel area has a first pixel electrode to which an image signal is applied, the image signal having a potential alternately switching between a positive polarity and a negative polarity with reference to a first central potential. The second pixel area includes a second pixel electrode to which a first driving potential is applied, the first driving potential having a potential alternately switching between a positive polarity and a negative polarity with reference to a second central potential, the first central potential and the second central potential having a potential difference set therebetween. Therefore, ionic impurities can be efficiently swept from the first pixel area to the second pixel area.
US11636816B2	Display device A display device incudes: a display panel including a plurality of pixels; and a dimming panel that is disposed between the display panel and a light source of light to be emitted to the display panel and includes a plurality of dimming pixels. When one of the pixels produces an output at highest luminance and the other pixels produce an output at lowest luminance to the display panel, the light is transmitted through a predetermined one of the dimming pixels located on an optical axis of the light that is emitted to the one of the pixels and through the other dimming pixels arranged around the predetermined dimming pixel. A degree of transmission of the light through the other dimming pixels decreases as the light is away along one direction from the predetermined dimming pixel, and there are a plurality of directions having different degrees of the decrease.
US11636814B2	Techniques for improving the color accuracy of light-emitting diodes in backlit liquid-crystal displays A display device includes an array of LEDs, an array of LCD pixels, and a display controller. The display controller is configured to compensate for one or more sources of color variation in light produced by the LEDs. The display controller can determine a first color variation at a given LCD pixel based on the distance between the given LCD pixel and one or more LEDs. The display controller can also determine a second color variation at the given LCD pixel based on a current level supplied to the one or more LEDs. The display controller configures the given LCD pixel to filter light that is received from the one or more LEDs in a manner that reduces or eliminates either or both of the first and second color variations.
US11636813B2	Display device, and method of operating a display device A display device includes a display panel including a plurality of pixels, an image data corrector configured to generate a corrected image data by adjusting an image data and a data driver providing data signals to the plurality of pixels based on the corrected image data. The image data corrector divides the display panel into a plurality of unit areas, and adjust the image data for a unit area among the plurality of unit areas by using a full image load for the entire display panel, a first image load for the unit area, and a second image load for peripheral unit areas surrounding the unit area among the plurality of unit areas.
US11636812B2	Degradation compensator, display device having the same, and method for compensating image data of the display device A degradation compensator including a compensation factor determiner configured to determine a compensation factor based on a distance between adjacent sub-pixels, and a data compensator configured to apply the compensation factor to a stress compensation weight to generate compensation data for compensating image data.
