Patent ID: 8619018

Claim:
A method of modifying pixel data applied to a display panel, the method comprising: obtaining block representative values of image blocks from pixel data of an input image, wherein the image blocks respectively correspond to a plurality of light-emitting blocks of a backlight assembly; determining duty cycles of the light-emitting blocks using the block representative values; determining boundary brightness values for boundary regions of the display panel between adjacent light-emitting blocks that are illuminated by light emitted by a light guide plate of the backlight assembly; calculating pixel brightness values using the duty cycles of the light-emitting blocks and the boundary brightness values, wherein the light is emitted from the light guide plate when a representative light-emitting block of the light-emitting blocks is driven; and compensating the pixel data based on the pixel brightness values, wherein the display panel is configured to receive the light from the backlight and the light-emitting blocks are adjacent a side surface of the light guide plate.
