Abstract

A computer that includes a processor and a memory, the memory including instructions executable by the processor to determine intensity values of emitted light for red, green, and blue (RGB) sub-pixels of an LCD device based on data displayed on the LCD device. A first percentage of RGB sub-pixels can be determined that have intensity values that exceed a sub-pixel threshold for a first LCD zone of the LCD device. A second percentage of a full intensity value of emitted light for the RGB sub-pixels in the first LCD zone can be determined based on the first percentage. Intensity values of the LEDs in a first LED zone can be set to the second percentage of the full intensity value.

Claims20

Dependent claims

A system comprising:

a computer including a processor and a memory storing instructions executable by the processor to:
determine intensity values of emitted light for red, green, and blue (RGB) sub-pixels of an LCD device based on data displayed on the LCD device;
determine a first percentage of RGB sub-pixels that have intensity values that exceed a sub-pixel threshold for a first LCD zone of the LCD device to indicate the presence of fine detail in the first LCD zone wherein the LCD device includes multiple LCD zones and the LCD zones include multiple pixels;
determine a second percentage of a full intensity value of emitted light for the RGB sub-pixels in the first LCD zone of the LCD device to increase the intensity value of the brightest pixel in the first LCD zone to a new maximum value based on the first percentage;
and
set intensity values of LEDs in a first LED zone to the second percentage of the full intensity value.
