摘要： A color adjustment method for a color sequential liquid crystal display (LCD) having at least one white light source is provided. In the color adjustment method, firstly, an original image signal is converted into a target color point located in a chromaticity diagram in a color space. Then, a modified image signal having white data is calculated according to the original image signal. Afterwards, the modified image signal is converted into a main color point located in the chromaticity diagram by using a matrix group. Then, a plurality of subfield data are calculated according to the main color point and the target color point. The subfield data are used for enabling the main color point to fall on the target color point.

摘要： The light control device provides fillings in the valleys of the prism elements, be it uniformly or non-uniformly arranged, which is made of UV and/or thermal curable resins of an appropriate refractive index different from that of the prism elements. The optical performance of the original prism elements can be altered by the following approaches. First, the refractive index of the fillings can be appropriately chosen. Second, the fillings can be up to an appropriate height (but never overruns the surrounding prism elements). Third, the distribution of the height or the refractive index of the fillings across the light emission plane can be “patterned,” that is, in accordance with the planar light intensity distribution produced by the light source.
