ABSTRACT:
In a light emitting apparatus, all pixels are fabricated using monochrome light-emitting materials. Since the light transmittances of color filters or color conversion layers are not uniform among red (R), green (G), and blue (B), exact white color cannot be displayed. In the present invention, dots for producing these colors of light, i.e., red (R), green (G), and blue (B), are arranged parallel to writing scan lines and to erasing scan lines. The brightnesses are made uniform by controlling the emission times of the emitted colors of light. According to the brightnesses obtained after passage through the colored layer with the lowest light transmittance, the emission times of colors of light passed through the other colored layers are shortened. Thus, as the brightness differences after passage can be reduced, the light emitting apparatus can display exact white color.
