Abstract

A projection display film with a large viewing angle and a preparation method thereof, comprising a sequentially stacked projection display layer, a substrate layer, an adhesive layer, and a release material layer; the raw material formula of the projection display layer contains 33.2%-99.6% glue Or / and resin, 0.1%-50% optical scattering material, 1‰-5‰ inorganic nano black pigment, 0.1-6.3% dispersant and 0.1%-10% curing agent. Wherein, the optical scattering material is a mixture of two or more materials with different refractive indices, and the optical scattering material is a mixture of two or more materials with different particle sizes. The optical scattering material of the projection display layer of the present invention is a mixture of two or more materials with different refractive indices, and the particle size of the optical scattering materials is also different, so that the viewing angle of the projection display film is larger.

Description

technical field [0001] The invention belongs to the field of display technology, in particular to a projection display film with a large viewing angle and a preparation method thereof. Background technique [0002] The transparent display technologies currently on the market mainly include: holographic display, TOLED (Transmissive Organic Light Emitting Device), reflective display and transparent LCD (Liquid Crystal Display, liquid crystal display). The problems of using traditional flat-panel displays include large volume, high heat, etc., and high cost, which limits the application of this technology. [0003] Projection display film (also known as projection display film) is a new type of projection imaging film at present. It has high visible light transmittance and can be attached to transparent glass for use. Generally, these projection display films contain some nano-diffusing particles, such as diamond particles, aluminum oxide particles, etc. When the projector is ...
