Self-luminous display device and terminal equipment

Abstract

The invention provides a display device. The display device is characterized by comprising a backlight unit, a first polarization layer, a liquid-crystal box, a second polarization layer and a fluorescent powder layer. The backlight unit comprises a light source, a light guiding plate and a diaphragm and is used for supplying backlight for the display device. The first polarization layer is used for allowing light with polarization component same as the polarization direction of the first polarization layer in the backlight to pass. The liquid-crystal box comprises a liquid-crystal layer and a liquid-crystal driving layer and is used for changing the polarization direction of the light from the first polarization layer. The second polarization layer is used for allowing the light with the polarization component same as the polarization direction of the second polarization layer in the liquid-crystal box to pass. The fluorescent powder layer is arranged on the second polarization layer. The display device is provided with the self-luminous characteristics based on time color mixture and can display one color by only one pixel without any subpixels, and quality of an integral image displayed is improved greatly. Further, the displayed image can be provided with a super-large visual angle, no color cast caused by the visual angle exists, and larger color gamut of the displayed color can be displayed.

Description

technical field [0001] The present invention relates to a self-illuminating display device and terminal equipment, more specifically, to a self-illuminating display device and terminal equipment based on temporal color mixing. Background technique [0002] Liquid crystal displays are smaller than traditional cathode ray tube (CRT) displays and thus take up less space. However, the color display performance of LCD monitors is not as good as that of CRT monitors. Since the CRT display uses electron beams to bombard the phosphor to emit light, the CRT display can be considered as a self-luminous display with a large color gamut, a large viewing angle, and a small color shift at a large viewing angle, which are precisely the shortcomings of liquid crystal displays. place. [0003] In addition, most of the existing display technologies are based on spatial color mixing, so we need to use three pixels or even more pixels to display one color. If one pixel is used to display mult...
