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: 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 method of rate control of a display device includes receiving compressed stress data for a slice of a display, decompressing the compressed stress data to obtain reconstructed stress data for the slice, adding additional stress data to the reconstructed stress data to obtain updated stress data for the slice, encoding the updated stress data at a first precision level (pc) to generate first updated compressed stress data for the slice, in response to a size (bc) of the first updated compressed stress data for the slice of the display exceeding a size (bt) of a buffer, determining a second precision level (p) based on the first precision level (pc), a third precision level (ps) of the additional stress data, and a fourth precision level (pb) of the buffer, and encoding the updated stress data at the second precision level (p) to generate second updated compressed stress data.
