Abstract: A thin backlight module and a manufacturing method of the thin backlight module are provided. The thin backlight module includes a drive substrate, multiple light emitting sources, a fluorescence layer, and multiple particle micro-structures. The light emitting sources are arranged in an array on the drive substrate. The surface micro-structures are arranged on a surface of the fluorescence layer. Each surface micro-structure is arranged corresponding to each light emitting source. Each particle micro-structure is arranged corresponding to each surface micro-structure. Each particle micro-structure and each surface micro-structure together form a guiding layer for dispersing light from a corresponding one of the light emitting sources. Thereby, a smaller light mixing distance and an ultra-thin backlight module thickness are achieved.

Abstract: The present disclosure provides a liquid crystal display and a display module thereof, the display module includes a lower polarizer, a TFT array substrate, a liquid crystal layer, a color filter and a upper polarizer. The display module further includes a metal electrode layer arranged between the color filter and the liquid crystal layer, the metal electrode layer includes a dielectric layer and a metal wire grid layer, and the metal wire grid layer is arranged on a surface of the dielectric layer facing the liquid crystal layer. The metal wire grid layer is used as a common electrode layer of the display module, thus replacing the traditional transparent electrode ITO and avoiding the problem that the transparent electrode ITO easily causes brittle fracture during bending resulting in electrical abnormality and at the same time can improve the contrast of the entire liquid crystal display.

Abstract: A display method and a display device of dynamically controlling backlight are provided. The present disclosure obtains a modified grayscale value of the input image in each of partitions by using the whole backlight reference value, the RGBW grayscale values of the input image in each of partitions, the normalized backlight output brightness value, and the spatial distribution function of the backlight brightness in each of partitions. The normalized backlight output brightness value of each of partitions is processed as a real backlight output brightness value which is outputted to a backlight driving circuit. The modified grayscale value is processed as a real grayscale value and then the real grayscale value is outputted to a display panel for display. The backlight and image grayscale of each of partitions are adjusted dynamically, thereby improving contrast space and power consumption and further, normally displaying the HDR contents in the HDR display.
