Abstract: A method of stress compensation in a display device includes retrieving, by a decoder, compressed stress data that is quantized by a quantization value, decoding, by the decoder, the compressed stress data to generate decoded data, generating a dither value based on the quantization value, and adding the dither value to the decoded data to compensate for quantization of the compressed stress data.

Abstract: A system and method for compressing video data. When a triplet of data values corresponding to a pixel differs sufficiently little from a previous, reference triplet, the difference is encoded using one of several encoding functions selected according to which of several criteria of similarity between the current triplet and the reference triplet is met. When none of the available criteria of similarity is met, the triplet is instead encoded using differential pulse code modulation with non-uniform quantization.

Abstract: In a method for transmitting video for a display panel between a transmitter in electronic communication with a receiver over a wireless communication channel, the method includes: receiving, by a transmitter, a data signal from a data source; receiving, by the transmitter, a return signal from a receiver; encoding, by the transmitter based on the return signal, the data signal utilizing a plurality of encoder blocks to generate a layered encoded data stream, wherein a first encoder block encodes the data signal and each subsequent encoder block encodes a difference between an input of a preceding encoder block and an output of a quantizer of a preceding encoder block; and transmitting, by the transmitter, the layered encoded data stream to the receiver for decoding and display on the display panel.

Abstract: A system and method for operating a display. In some embodiments, the method includes: permuting elements of a stress profile for a slice of the display, with a first permutation, to form a permuted stress profile; compressing the permuted stress profile to form a compressed permuted stress profile; decompressing the compressed stress profile to form a decompressed permuted stress profile; and permuting elements of the decompressed permuted stress profile, with a second permutation, to form a decompressed stress profile, the second permutation being an inverse of the first permutation.

Abstract: A system and method for transmitting compressed video. A transmitter receives uncompressed video data from a video source, and compresses it using one or more reference frames. A receiver receives the compressed video data and decodes it, using the same reference frames, to form display data. The reference frames are stored in compressed form in both the transmitter and the receiver. Each frame of display data becomes a reference frame for the decoding of a subsequent frame.

Abstract: A system and method for image testing is configured to apply at least one display property to a test image to generate a display modified test image and applying the at least one display property to a reference image to generate a display modified reference image. The system also applies a human eye model to the display modified test image to generate an eye modified test image and applies the human eye model to the display modified reference image to generate an eye modified reference image. The system may compare the eye modified test image with the eye modified reference image to determine human perceivable differences between the test image and the reference image.

Abstract: A system and method for operating a display. In some embodiments, the method includes: retrieving from a memory a first encoded stress profile and a first set of symbol statistics; processing, by a first decoder, the first encoded stress profile with the first set of symbol statistics, to form: a first decoded stress profile, and a second set of symbol statistics; augmenting the first decoded stress profile to form a second stress profile; processing, by an encoder, the second stress profile with the second set of symbol statistics to form a second encoded stress profile; and saving, in the memory, the second encoded stress profile.
