よシカラーディスプレイとして構成できる。[Detailed Description of the Invention] [Industrial Application Field] The present invention relates to a multicolor light source, and is characterized in that the point light source itself emits a wide variety of colors. To provide a display lamp capable of expression or a lamp for decoration. Furthermore, if a large number of light emitting diodes according to the present invention are used as picture elements and assembled, a 2-color display can be constructed using conventional techniques.
従来、多種類の色彩が得られる光源としてはカラーブラ
ウン管がある。Conventionally, a color cathode ray tube has been used as a light source that can provide a wide variety of colors.
上述したブラウン管は電子を高電圧で加速する構造を有
しているため従来の発光ダイオードと比べても格段に大
きいという欠点がある。Since the above-mentioned cathode ray tube has a structure in which electrons are accelerated with high voltage, it has the disadvantage that it is much larger than conventional light emitting diodes.
