    摘要: A color electroluminescent, EL, display device comprising an array of pixels (11) each comprising sub-pixels (1) of two or more colors (R, G, B). For at least one of the colors (R, G, B), the pixel (11) comprises a first sub-pixel (RL, GL, BL) comprising a first EL material and a second sub-pixel (Rc, Gc, Bc) comprising a second EL material. The first EL material is of higher lifetime than the second EL material; the second EL material has better color points and/or better color rendition properties than the first EL material. In some embodiments a pixel comprises two red sub-pixels (RL, Rc), two green subpixels (GL, Gc) and two blue sub-pixels (BL, Bc), one sub-pixel of each color (RL, GL, BL) comprising relatively high lifetime EL material and the other sub pixel of each color (Rc, Gc, Bc) comprising relatively good color points EL material. In other embodiments a pixel comprises two blue sub-pixels (BL, Bc) but only one red sub-pixel and one green sub-pixel.

    摘要: In an active matrix electroluminescent display, a plurality of rows of pixels are illuminated, defining at least two bands of rows separated by a non-illuminated band. The bands of rows of pixels scroll in the column direction over time, and at most 75% of the rows are illuminated at any point in time. This method is in essence a double bar scrolling method. By scrolling two bars, the required peak brightness is reduced as the effective overall duty cycle is increased. However, the period of illumination can still remain short, so that motion perception remains improved. The scrolling speed can be halved for the same frame rate or else the frame rate can be increased to reduce flicker.
