Display latency calibration for liquid crystal display
Abstract:
A system for calibrating a liquid crystal display (LCD) includes a plurality of temperature sensors, a storage medium, and a controller. Each temperature sensor measures a current temperature of at least one pixel in the LCD. The storage medium stores information about latencies for any LC-based pixel, wherein each latency corresponds to a time period for transition from a starting to an ending illumination state for one temperature of the LC-based pixel. The controller determines, based on the current temperature, the transition information and frame information, a time for each pixel in at least a portion of the LCD to transition from a first to a second illumination state. The controller computes, based on transition times, an LC transition time for at least the portion of the LCD and performs calibration of at least the portion of the LCD based on the LC transition time.
