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 operating a display. In some embodiments, the method includes: transforming a stress profile for a slice of the display, with a first transformation, to form a transformed stress profile; compressing the transformed stress profile to form a compressed transformed stress profile; decompressing the compressed stress profile to form a decompressed transformed stress profile; and transforming the decompressed transformed stress profile, with a second transformation, to form a decompressed stress profile, the second transformation being an inverse of the first transformation.

Abstract: A data communication system includes a transmitter, a channel, and a receiver includes a Clock and Data Recovery (CDR) phase detector that is configured to: calculate an overall pulse response of the data communication system; obtain a function value for each of a plurality of phases, the plurality of phases corresponding to a resolution per symbol; set a crossing phase to be a phase at which this value is minimum among the plurality of phase; and set the CDR locking phase to be the crossing phase plus a midpoint from among the plurality of phases.
