Abstract: In a color display device, when using white (W) sub-pixels in addition to subpixels of red (R) and green (G) plus blue (B) without increasing a wiring line number, the per-color pixel number in a unit area decreases so that the image resolution is deteriorated. The area and number of subpixels are adjusted in accordance with the visual sensitivity or luminosity required. Practically, the area of red (R) and blue (B) subpixels which are relatively low in luminosity is set to be about two times greater than the area of green (G) and white (W) subpixels that are relatively high in luminosity while letting the number of green (G) and white (W) subpixels be twice the number of red (R) and blue (B) subpixels. A larger subpixel is configured from a plurality of unit subpixels. A smaller subpixel is formed of a one unit subpixel.

Abstract translation: 在彩色显示装置中，在不增加布线数量的情况下，除了红色（R）和绿色（G）以及蓝色（B）的子像素之外，当使用白色（W）子像素时，单位的单色像素数 面积减小，图像分辨率下降。 子像素的面积和数量根据所需的视觉灵敏度或亮度进行调整。 实际上，发光度相对较低的红色（R）和蓝色（B）子像素的面积被设定为大于发光度相对较高的绿色（G）和白色（W）子像素的面积的两倍，而 使绿（G）和白（W）子像素的数量是红（R）和蓝（B）子像素的数量的两倍。 较大的子像素由多个单位子像素构成。 较小的子像素由一个单位子像素形成。
