    • An object of the present invention is to provide a color image display apparatus which can easily display a full-color animation of VGA class and attains reduction in size and lowering of price and which facilitates full-color gradation control. In order to achieve the object, a color image display apparatus includes a shutter control circuit that slices color component data subjected to color separation in accordance with a slice level, a light source control circuit that controls a light source corresponding to the color component data, one or plural light sources a converting device that converts light from the light source to surface light source light, a shutter which makes light of a corresponding pixel pass therethrough and cuts off the light and which is made of liquid crystal as a main material, and a timing circuit that generates operation timings for the shutter control circuit and the light source control circuit, in which the shutter control circuit transfers one line of slice data to the shutter sequentially on a slice level basis, the light source control circuit turns on the light source corresponding to the source data, and the shutter makes the light from the light source, which corresponds to the slice data representing gradation of the pixel, pass therethrough and cuts off the light to display an image.
    • 本发明的目的是提供一种可以容易地显示VGA类的全色动画并实现尺寸减小和价格降低的彩色图像显示装置,并且便于全色渐变控制。 为了实现该目的,彩色图像显示装置包括:快门控制电路,其对根据切片电平进行分色的色彩成分数据进行切片;光源控制电路,其控制与色成分数据对应的光源; 一个或多个光源,将来自光源的光转换为面光源的转换装置,使相应像素的光通过的遮光板切断光并由液晶作为主要材料, 定时电路,其生成用于快门控制电路和光源控制电路的操作定时,其中快门控制电路以片级顺序将一行切片数据顺序地传送到快门,光源控制电路接通光 源对应于源数据,并且快门使来自光源的光对应于切片数据 表示像素的灰度,通过并切断光以显示图像。
