摘要： In a machine-implemented method of local dimming a light source of a light source block for driving the light source block to provide a plurality of image regions with light, duty ratios of a first light source and a second light source adjacent to the first light source are initially determined by using a first target luminance value of a first image region closest to the first light source and a second target luminance value of a second image region closest to the second light source. The initially determined duty ratios are compensated by using a target luminance value of a remaining image region excluding the first and second image regions among the image regions receiving the light generated from the first and second first light sources. The first and second first light sources are driven by using the compensated duty ratios.

摘要： An optical element includes a light-transmitting structure and a first reflection-prevention layer. The light-transmitting structure has a first surface and a second surface facing the first surface. The first reflection-prevention layer includes a plurality of first light-refractive index buffering particles deposited on the first surface such as the concentration of the particles decreases as the distance from the first surface increases. The first reflection-prevention layer decreases the variation of a light-refractive index from the light-transmitting structure to an air layer to decrease the light reflectance of the first surface. Therefore, the light transmittance of the light-transmitting structure is increased due to the reflection-prevention layer formed on a surface of the light-transmitting structure, so that luminance may be enhanced. Moreover, the reflection-prevention layer may enhance the resistance of the light-transmitting structure to external impacts.
