Abstract:
Techniques for driving a dual modulation display include generating backlight drive signals to drive individually-controllable illumination sources. The illumination sources emit first light onto a light conversion layer. The light conversion layer converts the first light into second light. The light conversion layer can include quantum dots or phosphor materials. Modulation drive signals are generated to determine transmission of the second light through individual subpixels of the display. These modulation drive signals can be adjusted based on one or more light field simulations. The light field simulations can include: (i) a color shift for a pixel based on a point spread function of the illumination sources; (ii) binning difference of individual illumination sources; (iii) temperature dependence of display components on performance; or (iv) combinations thereof.

Claim (Index 2):
An apparatus comprising:\n logic controlling one or more illumination sources of a backlight configured to emit first light onto one or more light conversion layers, the one or more light conversion layers configured to be stimulated by the first light and to convert at least a portion of the first light into second light; logic to control one or more light modulators, the one or more light modulators configured to modulate light transmitting through individual subpixels; logic to perform at least one light field simulation for color shifts as a function of respective distances that the first light emitted from the one or more illumination sources travels before being converted into the second light; logic to adjust drive values for the one or more light modulators based the at least one light field simulation.
