Description
Technical Field
The utility model relates to a liquid crystal electronics license plate technical field especially relates to an anti UV liquid crystal electronics license plate.
Background
Along with the progress of society and the improvement of living standard of people, the electronic application degree is continuously improved, and liquid crystal display screens such as electronic license plates for outdoor use are widely used in developed countries such as the United states.
The outer layer film used for the liquid crystal electronic license plate is a common smooth PET base film at present, and the surface of the PET base film does not have an anti-UV function, so that liquid crystal on the inner layer is aged and discolored under UV light irradiation to influence the display effect. In order to avoid UV light irradiation, it is known to coat a UV reflective layer on the ITO conductive film of the liquid crystal display to reduce the influence on the liquid crystal by reflecting the UV light back. However, this technique is not easy to control the color, transparency and uniformity of plating due to the thin plating layer and the purity of plating material (oxide), which also affects the display effect, and the difference of the reflection effect of UV also causes a certain defect and deficiency in the protection of liquid crystal.
PICASUS-UV film from torray corporation of japan is a nano-laminated PET film with light transmittance: wavelength 375nm below >70%, wavelength 450nm >75%, wavelength 500nm >80%, ultraviolet light reflectance: wavelength 375nm-400nm >80%, high transparency and UV-blocking optical properties.
SUMMERY OF THE UTILITY MODEL
The to-be-solved technical problem of the utility model is according to the not enough of above-mentioned prior art, provide an anti UV liquid crystal electronic license plate, it can avoid UV light to improve life to shining of liquid crystal.
The technical scheme of the utility model as follows:
an anti-UV liquid crystal electronic license plate comprises cover plate glass, a liquid crystal display, a control module, an assembling frame, a battery hanging plate and an assembling rear plate, wherein the cover plate glass is assembled from front to back; the back of the cover plate glass is laminated with a PICASUS-UV film through an OCA optical adhesive layer, and the PICASUS-UV film is positioned in front of the liquid crystal display.
Further, the thickness of the OCA optical adhesive layer is 20-30um, and the thickness of the PICASUS-UV film is 100-145 um.
Compared with the prior art, the utility model discloses following beneficial effect has:
(1) the PICASUS-UV film reflects UV light, so that the service life is prolonged, processes such as electroplating are not needed, the process is simple and environment-friendly, and the problem of surface oxidation in the electroplating process is solved.
(2) The back of the cover plate glass is laminated with a PICASUS-UV film through an OCA optical adhesive layer, the function of an explosion-proof film can be served, and the cover plate glass can be prevented from splashing when the glass is broken.
