摘要
A display controller generates a backlight illumination field (BLIF) based on a coarse point-spread function (PSF) and a correction PSF. The display controller samples the coarse PSF to accumulate light contributions from a larger neighborhood of LEDs around a given LCD pixel. The display controller samples the correction PSF to generate correction factors for a smaller neighborhood of LEDs around the given LCD pixel. The display controller interpolates samples drawn from the coarse PSF and samples drawn from the correction PSF and then combines the interpolated samples to generate a full resolution BLIF.
