Abstract

The invention belongs to the technical field of display, and particularly relates to a composite polaroid, a method for preparing the composite polaroid and a display device. The composite polaroid comprises a quantum dot assembly, a first laminating adhesive layer and a polaroid assembly which are stacked in sequence. Therefore, the composite polaroid has the effect of improving the color gamut. Specifically, when the composite polaroid is applied to an LCD product, the quantum dot assembly can be excited through the blue light emitting diode in the backlight module, and the optical effects of pure color gamut, wide color gamut and image quality improvement are achieved. In addition, the composite polaroid further has the effect of controlling whether light passes through or not. Besides, the composite polaroid is used in the LCD product, the backlight design of the current LCD product is not changed, and the composite polaroid is suitable for LCD products with various sizes.

Description

technical field [0001] The invention belongs to the field of display technology, and in particular relates to a composite polarizer, a method for preparing the composite polarizer and a display device. Background technique [0002] For the design of electronic products, consumers are not only pursuing large display screens and thinning, but also pursuing a more perfect visual experience. Currently, OLED (Organic Light-Emitting Diode) products can achieve a color gamut greater than 100% NTSC, and the color is more accurate. Bright, layered, and high color reproduction can bring users a better look and feel. However, the color gamut of LCD (Liquid Crystal Display) products is 96% NTSC or even lower, and there is a big gap compared with OLED products. In order to further narrow the color gamut difference between the two, and improve the competitiveness of LCD products in the future market , it is of great significance to develop a product that can improve the poor color gamut ...
