Abstract
A display controller progressively updates LEDs and LCD pixels in scanline order as portions of an image are scanned into a frame buffer. The display controller analyzes a first portion of the image that includes a first pixel value associated with a first LCD pixel. The display controller identifies a first LED that contributes luminance to the first LCD pixel and determines an LED current setting for the LED based on the first pixel value. The display controller then identifies a second LCD pixel that resides above the first LED and is associated with a second pixel value. The display controller configures the second LCD pixel based on the second pixel value and luminance contributions received at the second LCD pixel. Accordingly, the display controller need not wait for the entire image to be scanned into the frame buffer before initiating display of the image.
