    摘要: The disclosure relates to a system and method for determining pixel intensity values (luma values) for an image being displayed on a display of an electronic device, then adjusting the pixel intensity and the backlight level for the image that is output to a liquid crystal display (LCD). The system comprises: a display for displaying an image to be displayed on the device; an image adjustment module to identify the pixel intensity values of the image, to determine new pixel intensity values for the image based in part on the original pixel intensity values, to provide the (adjusted) image at the new pixel intensity values to the display and to determine a backlight level for the image at the new pixel intensity values. The system further comprises a backlight system to provide a backlight for the adjusted image at the adjusted backlight level.

    摘要: A system and method for compensating for non-uniform illumination from a light guide for a display in an electronics device is provided. The system comprises: a memory device storing a data representing a first compensation pattern for generation on the display to block light from a first portion of the light guide relative to light from a second portion of the light guide; a first module to incorporate the stored representation into an image to be displayed on the display; and a second module to generate the image with the stored representation for display on the display. In the system, when the first module generates the first compensation pattern on the display, the first compensation pattern aligns with the first and second portions to reduce an intensity of light from a light source passing through the first compensation pattern from the first portion relative to an intensity of light passing through the first compensation pattern from the second portion from the light source.
