Abstract:
A display system with temperature compensation includes (a) a backlight unit containing a light emitting diode (LED) array, (b) a liquid crystal display (LCD) containing a plurality of pixels for spatially modulating, according to respective LCD drive values of the pixels, transmission of light generated by the LED array, (c) a plurality of temperature probes mounted to the backlight unit for measuring a respective plurality of temperatures at the LED array, (d) a light-field simulator for simulating, at least in part based upon the temperatures, a light field at the LCD as generated by the LED array, and (e) an LCD drive solver for processing a target image and the light field simulated by the light-field simulator, to determine the LCD drive values required to display the target image as compensated for temperatures of the LED array.

Claim (Index 18):
A method for temperature compensation of a light-emitting diode (LED) backlit liquid crystal display (LCD) system, comprising:\n receiving a target image; receiving a plurality of temperatures measured at different respective spatial locations of a backlight unit, the backlit unit including an LED array configured to back-illuminate an LCD; simulating, at least partly based upon the temperatures, a light field at the LCD as generated by the LED array; processing the target image and the light field generated by said simulating, to determine LCD drive values of pixels of the LCD required to display the target image as compensated for temperatures of the LED array; and sending the LCD drive values to an LCD controller configured to control the pixels.
