とにより所望の色を合成することができる。The light emitting elements 1a, 1b, ... 1n, 2a, 2b, ... 2n, ... ma, mb, ... mn are light emitting diodes having different light emission wavelengths, and have three primary colors of light.
That is, an arbitrary color can be created by combining red (R), green (G), and blue (B). By arranging these three color light emitting diodes in a concentrated manner and changing the light emission intensity of each light emitting diode, A desired color can be synthesized.

イオードからの発光の合成として得ることができる。With respect to light emitting diodes, the half width of the emission spectrum is as narrow as several tens of nm, and color correction of intermediate colors cannot be sufficiently performed with three colors in some cases.

下させることはない。When arranging the light emitting diodes in a lattice, a plurality of light emitting diodes may be molded at once,
Alternatively, separately molded parts may be concentrated. That is, the light emitting diode element (chip) is about 300 μm × 300
Since it can be as small as μm or more, even if a plurality of, for example, three or five pieces are molded at a time, the size can be reduced and the image resolution of the color display device does not decrease.

間の目の視感度等により決められる。FIG. 3A is a diagram for explaining an example of a time chart of a time-series pulse for a required light-emitting element when an arbitrary visible light is generated. In the figure, the horizontal axis is time t, the vertical axis is light output P, and R, G, B are red, green, and blue signals. T is the period of the pulse, which is determined by the operation frequency, and the pulse width t 0 is the time determined by the number of light emitting elements (the total number of pixels). The color of light emitted from the light emitting element is controlled by the ratio of the current values of red R, green G, and blue B. That is, a color is created by changing the ratio of the current value flowing to each light emitting element. For example, in the case of orange, blue B is not illuminated, and current is made to flow at a certain ratio between red R and green G. This ratio is determined by the efficiency of each light emitting element, the visibility of human eyes, and the like.

Each illuminant is driven at a carrier frequency with t 1 having a pulse width sufficiently smaller than t 0 . By changing the ratio of the number of pulses entering into t 0 (the ratio of n R , n G , n B ),
Any color can be combined. Of course, the emission intensity can be controlled by changing the light output.

電力、高分解能にて構成できる利点を有する。The color display device of the present invention uses a plurality of light-emitting elements having different emission wavelengths and synthesizes any visible light by a time-series pulse. The high sensitivity has the advantage of being able to bend the whole device or the display part by wiring one electrode by vapor deposition or plating on the flexible substrate as well as the wall-mounted display, and to be able to carry as a scroll. Color display device can be realized. Also, when a light emitting diode is used as a light emitting element, there is an advantage that an extremely bright image can be formed with low power and high resolution as compared with other light emitting elements.
