Embodiment Construction

[0030] Embodiments of the present invention will now be described in more detail with reference to the accompanying drawings.

[0031] figure 1 is a schematic diagram of the characteristics of the present invention applicable to electrochromic pigments.

[0032] refer to figure 1 Explain that the electrochromic pigment 1 changes its color image with the voltage added by the voltage variable regulator 2 . exist figure 1 In the case of , the above-mentioned electrochromic pigment 1 is transparent at the electric magnetic pole, that is, when no voltage is applied, however, it gradually turns red as the electric magnetic pole rises.

[0033] The present invention utilizes the characteristics of the electrochromic pigment 1 whose color image changes with the electric magnetic poles to compensate for the part that reduces color image reappearance.

[0034] figure 2 It is a schematic diagram showing an example of a colored electrochromic dye mounted on a screen according to an ...

Abstract

The invention relates to an image display device, especially an image display device using color compensation device that uses electric change color pigment to compensate image color. It includes the first transparent plate and the second transparent plate. Electric change color pigment is set between the two plates. Screen of electrode is set at the two ends of electric change color pigment. The voltage changeable section is powered on the electrode. The method of the invention does not need to adjust input voltage standard or to change optical component to take compensation color image, thus it could not only maintain the efficiency of light but also maintain the purity of color.

Description

technical field [0001] The invention relates to an image display device, in particular to a color compensation device for an image display device which uses electrochromic pigments to compensate image colors. Background technique [0002] Manufacturers of video display equipment such as televisions and monitors have made great efforts to make the displayed images close to natural colors. However, according to the characteristics of actual display components, there is still a long way to go to achieve the reproduction ability of a part of the color image. [0003] As an example, recently, in the case of a DLP (digital light processing) projector that receives various lights as a projective video display, the color ring used to separate red, green, and blue ( The design angle of each color segment of the color wheel is different, and the color image reproduction ability is different. [0004] When the redisplay ability of traditional characteristic colors (such as: red, gree...
