Definitions

  • the above-described conventional image display device has the power to display only white gradations equivalent to the number of gradations of the R, G, B, and W sub-pixels.
  • FIG. 6A is a plan view showing a state where the first white gradation and the second white gradation are displayed in the pixel 6.
  • the shaded portion indicates that the gradation value is smaller than the portion not shaded, that is, ⁇ .
  • the difference between the first white gradation and the second white gradation is one gradation.
  • the light-dark relationship between RGB and W that is, the first white gradation and the second, in the odd and even rows of the pixels 6 arranged in the liquid crystal panel 5.
  • the light / dark relationship with the white gradation is reversed.
  • the light and dark become a checkered pattern by reversing the light and dark relationship in adjacent rows.
  • the color mixture of the first white gradation and the second white gradation can be made more natural.
  • Table 4 shows an example of conversion processing performed by the gradation level-RGBW converter 2 when the light-dark relationship is reversed.
  • the gradation of (R, G, B), that is, the first white gradation, and the gradation of (W), that is, the second white gradation are (first white gradation) ⁇ (2nd white gradation), that is, the 1st white gradation is combined to become brighter.
  • (first white gradation) ⁇ (second white gradation) that is, the second white gradation is combined so that it is brighter. Therefore, for example, by applying the combinations shown in Table 3 to odd rows and applying the combinations shown in Table 4 to even rows, it is possible to display a light and dark checkered pattern as shown in Fig. 6 (b). Monkey.
  • the method of combining the first white gradation and the second white gradation on the liquid crystal panel 5 is not limited to the combination of the above pine pattern.
  • it is visually recognized as a third white gradation in which the first white gradation and the second white gradation are combined. That is, any arrangement is possible as long as the first white gradation and the second white gradation are mixed and visually recognized as the third white gradation.
  • the gradation is equal. This is because the light transmittance in each of the R, G, and B subpixels is about 1Z3, and the light transmittance in the W subpixel is about 1.
  • the R, G, B, and W subpixels all have the same area. Compared to the case, a richer gradation expression can be realized. In this case, the area of the R, G, and B subpixels increases, so the R, G, B, and B subpixels have the same color density compared to the R, G, B, and W subpixels. Becomes higher.
  • a rich magenta gradation can be expressed.

Abstract

Un affichage à cristaux liquides (1) comprend un convertisseur rouge-vert-bleu-blanc (RGBW) de niveau de gradation (2) servant à créer une première gradation du blanc et une deuxième gradation du blanc. Cet affichage permet d'étendre le nombre de gradations du blanc, la première gradation du blanc et la deuxième gradation du blanc créées par le convertisseur RGBW de niveau de gradation (2) étant combinées sur un panneau à cristaux liquides (5) et étant visibles en tant que troisième gradation du blanc.
