METHODS FOR DISPLAY WITH DOUBLE MODULATION WITH LIGHT TRANSFORMATION Russian patent published in 2017 - IPC G09G3/20 

FIELD: physics.

SUBSTANCE: to drive a dual-modulation display, backlight excitation signals are generated to drive separately controlled light sources. The light sources emit the first light onto the light-converting layer. The light-converting layer converts the first light into the second light. The light-converting layer may contain quantum dots or crystalline phosphors. Modulating excitation signals are generated to determine the passage of the second light through the individual subpixels of the display. The colour shift for the pixel is determined, depending on the backlight excitation signals and the corresponding distances between the pixel and more than one separately controlled light source. Modulating excitation signals are adjusted depending on one or several simulation models of the light field.

EFFECT: increasing display performance and eliminating harmful heat.
