    Abstract: A method for compensating for characteristics of a transistor. In some embodiments, the method includes: measuring an error value, the error value being a difference between: a target current and a current driven by the transistor when the transistor is controlled by a compensated control signal based on an input control signal; adding to a first compensation parameter a first adjustment; adding to a second compensation parameter a second adjustment; and applying to a gate of the transistor a voltage equal to the sum of: the second compensation parameter, and the product of: the first compensation parameter, and an uncompensated drive voltage.

    Abstract: A method to transport forward error correction (FEC) codes in a symbol encoded transmission stream includes encoding a data stream from a data source into data symbols using computing circuits, generating first FEC codes from the data symbols using the computing circuits, encoding the first FEC codes into first FEC symbols using the computing circuits, merging the data symbols and the first FEC symbols into the transmission stream using the computing circuits, and transmitting the merged transmission stream to a sink device using the computing circuits. The encoding of the data stream into the data symbols and the encoding of the first FEC codes into the first FEC symbols may include the same encoding technique.

    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.
