A display system includes: a light source system configured to emit light beams; a scanner configured to scan the light beams on the surface of a spatial light modulator in the form of a light spot, the light spot corresponding to multiple pixels of the spatial light modulator; a spatial light modulator configured to modulate, according to an image modulation signal from a processing and control system, the light spot projected onto the spatial light modulator by the scanner to output image light; a processing and control system configured to output a light source timing modulation signal to a light source modulation device according to an input image signal and output an image modulation signal to the spatial light modulator; and a light source modulation device configured to adjust the output brightness of the light source system according to the light source timing modulation signal.

Display system

A color display panel and a control method thereof are provided. The color display panel includes pixel units arranged in an array, and each pixel unit at least includes a red sub-pixel unit, a green sub-pixel unit, a blue sub-pixel unit, and a white sub-pixel unit, where white light of the color display panel is achieved through the white sub-pixel unit. With aid of the above, the white light of the color display panel of the disclosure is realized by a single white sub-pixel unit, which can effectively alleviate color separation during mixing of red, green, and blue light of traditional display panels, and greatly improve the display effect of the display panel.

Color display panel and control method thereof

A composite ceramic with improved mechanical performance and a preparation method therefor. The composite ceramic comprises fluorescent powder, a ceramic matrix, and an optional sintering aid. The weight ratio of the fluorescent powder to the ceramic matrix is from 3:17 to 9:1, and the relative density of the composite ceramic is greater than 95%. The preparation method comprises using core shell-structured coated fluorescent powder as a raw material, and ball-milling and sintering the raw material to obtain the composite ceramic.
