The invention provides black edge display glass and a black edge display system. The black edge display glass comprises a light-transmitting area and a shielding area. At least one display area is arranged in the shielding area. The black edge display glass comprises an outer glass plate, an inner glass plate, a bonding layer and a reflecting layer. The outer glass plate comprises a first surface and a second surface which are arranged oppositely, the inner glass plate comprises a third surface and a fourth surface which are arranged oppositely, and the bonding layer is connected between the second surface and the third surface. The reflecting layer is arranged between the inner glass plate and the outer glass plate and at least covers the display area. When the black-edge display glass is installed on a vehicle, the distance between the top end of the reflecting layer and the fourth surface is larger than the distance between the bottom end of the reflecting layer and the fourth surface in the thickness direction of the black-edge display glass. The black-edge display glass provided by the invention can solve the technical problems that the black-edge display image of the display area has ghosting and the display image is not clear.

This invention discloses a high-transparency display system based on photoluminescence, comprising: a light source system; an imaging system for generating an image; and a projection system for projecting the image onto a display panel. The display panel has a light-incident surface and a display surface. A second ray is positioned between the imaging system and the projection system, and a third ray is positioned between the projection system and the display panel. The angle between the second ray and the third ray is greater than 0° and less than 180°. The third ray is projected from the light-incident surface onto the display surface. The high-transparency display system of this invention has a simple and compact structure and a small size.

The utility model provides a transparent bottom painting pasting film which comprises an ink absorbing layer, a base material layer, a white color developing film layer, a light reflecting layer, an adhesive layer and a release film layer from top to bottom, a plurality of light holes are evenly distributed in the white color developing film layer, and a plurality of protruding embossments are densely distributed on the face, making contact with the release film layer, of the adhesive layer. According to the transparent bottom painting pasting film disclosed by the utility model, the white developing film layer is arranged below the base material layer, so that an image painted on the ink absorption layer can be clearly displayed, the contrast of the image on the ink absorption layer is enhanced, and the image is more clearly displayed; the reflective layer is arranged on the white developing film layer, so that light can penetrate through the light holes and is reflected by the reflective layer at night, and an image can be observed at night; the adhesive layer is provided with the embossed lines, and exhaust channels can be formed between the embossed lines, so that exhaust can be performed in time during film pasting, and bubbles are prevented from being generated.

The invention discloses a preparation method of surface plasmon enhanced Mn < 4 + > doped double perovskite fluorescent powder, which comprises the following steps: S1, selecting specific A, B 'and B' 'source compounds, mixing according to a stoichiometric ratio, adding zirconium oxide balls into a ball milling tank, carrying out planetary ball milling for 3-8 hours, putting into an alumina crucible, sintering at 900-1300 DEG C for 6-15 hours to obtain a substrate, cooling, carrying out particle size treatment, and carrying out XRD detection; s2, selecting a Mn < 4 + >-containing compound according to the concentration of 0.1-5 mol%, and carrying out ball milling on the Mn < 4 + >-containing compound and And S3, carrying out metal nanometer treatment on a metal salt solution and the material obtained in the previous step. The luminous efficiency of the fluorescent powder is remarkably improved, the intensity can be improved by 30%-50% compared with that of traditional fluorescent powder, color regulation and control are accurate, multicolor fluorescence emission can be achieved, the color saturation and luminous efficiency can be improved when the fluorescent powder is applied to a display technology, the color rendering index and luminous efficiency can be improved when the fluorescent powder is used for illumination, and the anti-counterfeiting effect in the anti-counterfeiting field is enhanced; the chemical stability is good, the preparation is easy to control, and industrial production and multi-field application expansion are facilitated.
