摘要:
A full-color, light-emitting display device has improved efficiency with a large color gamut. The full-color, light-emitting display device has a plurality of pixels, each pixel having four or more colors of light-emitting elements. Three of the colors of light-emitting elements emits red, green, and blue light, and at least one of the colors of light-emitting elements emitting light is perceived to be within the gamut defined by the chromaticity coordinates of the red, green, and blue colored light-emitting elements. The light-emitting elements for emitting red, green, and blue colors of light each comprise a different species of inorganic light-emitting particles for emitting a different color of light. Each of the red, green, and blue species produces light having an emission spectrum with a full-width, half-maximum of less than or equal to 70 nm.
摘要(中):
全彩色发光显示装置具有较大的色域效率。 全色发光显示装置具有多个像素,每个像素具有四种或更多种颜色的发光元件。 发光元件的三种颜色发出红色,绿色和蓝色光,并且发光的发光元件的颜色中的至少一种被感知为由红色,绿色和蓝色的色度坐标定义的色域内, 和蓝色发光元件。 用于发射红,绿和蓝色光的发光元件各自包含用于发射不同颜色的光的不同种类的无机发光颗粒。 红色,绿色和蓝色物种中的每一种产生具有全宽半衰期小于或等于70nm的发射光谱的光。
