Self-luminous display device and terminal equipment

Abstract

A display device is provided, which is characterized in that it includes: a backlight unit, including a light source, a light guide plate and a diaphragm, for providing backlight for the display device; a first polarizing layer for neutralizing the backlight with the third A polarizing layer with the same polarization direction transmits the light polarization component; the liquid crystal cell includes a liquid crystal layer and a liquid crystal driving layer, used to change the polarization direction of the light from the first polarizing layer; a second polarizing layer, used to make the light from the first polarizing layer In the light of the liquid crystal cell, the light with the same polarization component as the polarization direction of the second polarization layer is transmitted; the phosphor layer is located on the second polarization layer. The display device provided by the present invention has self-luminous characteristics based on time-based color mixing. It can display one color using only one pixel without sub-pixels, which greatly improves the quality of the entire displayed picture; and, the displayed picture It can have a large viewing angle without any color shift caused by the viewing angle, and the color gamut of the colors that can be displayed is also larger.

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...
