Drawings
FIG. 1 is a schematic view of a projection screen with oleophobic layer according to the present utility model.
Description of the embodiments
The utility model will be further described with reference to the drawings and preferred embodiments.
FIG. 1 is a schematic diagram of a preferred embodiment of the present utility model.
As shown in fig. 1, a projection screen with an oleophobic layer according to this embodiment includes: 1, a screen substrate layer; 2, a crystal structure layer; 3, a crystal structure gain layer; and 4, a transparent oleophobic protective layer.
A projection screen with an oleophobic layer in this embodiment is a screen substrate layer, preferably PC or PVC or PET, which has high strength and is suitable for crystal coating and spraying operations. Above the substrate is a crystalline structure layer, preferably a diffuse crystalline polymer layer or multiply superimposed nanoparticle cubes, the multiply scattering of which can be used to diffuse light, increasing the path length range or equivalent time delay of light within the screen. Speckle effects can be reduced if the distribution of the path length of the light is greater than the coherence length of the light. The crystal structure gain layer is arranged above the crystal structure layer, and the screen with higher gain can lead the brightness of the picture to be more concentrated, and the imaging effect to be better (namely, the imaging picture with brighter, rich layers and bright colors). The crystal structure gain layer of the present embodiment may include a crystal gain spray coating layer, an individual crystal gain structure layer, and a reflective gain layer. The preferred solution for the crystal structure gain layer spray coating and the individual crystal gain structure layers is a crystalline polymer layer of the same material as the crystal arrangement layer. The crystal structure gain layer can adopt an electroplating mode, and the preferred crystal structure gain layer is made of one or a mixture of magnesium, aluminum, nickel, silver and titanium dioxide, and further, the crystal structure gain layer can also comprise a fluorescent whitening agent, and the fluorescent whitening agent can absorb invisible ultraviolet light and convert the invisible ultraviolet light into blue light or purple visible light with longer wavelength, so that the unwanted yellowish color in a matrix can be compensated, and more visible light can be reflected.
The comprehensive adoption of each crystal layer and each gain layer can obviously achieve the following purposes: the length of interaction from the incident light with the projection screen is increased. Each of these coatings may provide and/or aid in the anti-speckle effect. These coatings may work together to enhance the anti-speckle effect they each provide. Further, each of these coatings can work in combination to increase the range of path lengths or time delays that incident light can take within the screen to reduce speckle and improve contrast and uniformity of the screen. And after multiple diffusions and reflections, the incident light can exit the screen at various angles (much greater than the range of 50 to 80 degrees, 50 to 80 degrees also being the effective diffusion angle for a common movie screen). The reflection and diffusion of the incident light for many times of 50-80 degrees in the embodiment can make the light emergent from each angle at the front end of the screen, which effectively overcomes the defect of poor viewing effect, i.e. low effective scattering angle, of the left and right sides of the traditional screen.
The transparent protective layer is formed by coating the transparent optical polyester film with an shadowless adhesive and attaching a transparent polyester film protective film on the hardened surface.
The uppermost layer of the screen is a transparent oleophobic protective layer, the transparent oleophobic protective layer takes a molecular structure mainly comprising fluorine titanium, is coated on the surface of the reflecting layer in a mist form, and forms a protective layer through high-temperature reaction with light, so that the effects of water resistance, moisture resistance, dust resistance, scratch resistance, wear resistance, oxidation resistance and oil stain resistance are achieved.
The foregoing is a further detailed description of the utility model in connection with the preferred embodiments, and it is not intended that the utility model be limited to the specific embodiments described. It will be apparent to those skilled in the art that several simple deductions or substitutions may be made without departing from the spirit of the utility model, and these should be considered to be within the scope of the utility model.
