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 1):
A display system, comprising:\n one or more illumination sources of a backlight configured to emit first light, the first light including at least one of UV spectral components or blue light spectral components; 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 and recycled light into second light, the one or more light conversion layers including quantum dots; logic to compute 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; and a controller to adjust drive values for one or more light modulators based on the logic.
