A display device 10 has a display unit with at least one array of light sources which are selectively switchable to on and off states. The light sources 16 are arranged in groups of three in closely spaced configuration and the sources in each group arranged to emit different colored light when operated so that, when viewed from a distance, the color of each group can be varied in accordance with which of the sources within a group are illuminated. The sources each comprise an electric filament lamp and an associated colour filter. The sources in each group are arranged to emit light having respective CIE 1931 chromaticity coordinates substantially as follows: y SIMILAR 0.3 x SIMILAR 0.7; y SIMILAR 0.4 x SIMILAR 0.6; and y SIMILAR 0.7 x SIMILAR 0.3, respectively. The device 10 includes a peripheral facia 100 colored in at least two colors which are visually distinguishable one from the other, and being of low reflectivity. By control of the switching different color patterns or a moving image is displayed. The color of the light sources may be chosen to be red, green and orange. <IMAGE> |
