Abstract: Adjust a backlight of a display device according to image loading and edge statistics of an input image. When the input image is a dark scene and includes relatively more edges, a luminance of the backlight would be controlled according to the image loading of the input image and compensated the backlight for showing details of the input image clearly. When the input image is a dark scene with negligible edges, the luminance of the backlight would be controlled by image loading with no or few compensation for lowering the power consumption. When the input image is a bright scene, or when the input image includes no edge or only negligible edges, minimum compensation is applied to the backlight for lowering the power consumption.

Abstract: An adjustable back-lighting structure for a keyboard includes a light guide panel having vertical peripheral edges and at least one light entering surface; and a surrounding edge made of plastic or chemical macromolecule compound material, having a connecting interface tightly bonded with the vertical peripheral edges of the light guide panel. The connecting interface can generates the feedback beam Bf to enhance the illumination effect. Therefore, the light transmission in the light guide panel can be limited in the upper and lower surfaces without leakage at the vertical peripheral edges.
