Abstract

The invention provides a transparent display film containing silicon dioxide hollow spheres and a preparation method and an application of the transparent display film, which belong to the technical field of films for projection. The transparent display film comprises a projection display layer, a base material layer, an adhesive layer and a release material layer which are stacked in sequence, and the projection display layer comprises nano magnetic silicon dioxide hollow spheres. According to the invention, the nanometer magnetic silicon dioxide hollow spheres are added into the projection display layer; the nano silicon dioxide hollow spheres are uniform in particle size distribution and have ultrahigh specific surface area, narrower pore size distribution and larger pore volume, when light is projected to the projection display layer, the propagation path of the light is lengthened, the retention time of the light is prolonged, and the utilization rate and the light transmittance of the light are effectively improved, so that the optical imaging capability and the projection display effect are enhanced.

Description

technical field [0001] The invention relates to the technical field of projection films, in particular to a transparent display film containing silicon dioxide hollow spheres and a preparation method and application 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 traditional flat panel display include large volume, high heat, unclear projection, 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, ...
