In addition, in the present embodiment, the fixing bracket 3 is used to fix the protective cover 2, the display panel 1, and the optical film 4 together, the area of the protective cover 2 is larger than the area of the optical film 4 and the display panel 1, and after the protective cover 2 is covered, the peripheral edge of the protective cover 2 exceeds the peripheral edges of the display panel 1 and the optical film 4. Be provided with the line of location (not shown in the figure) on the protection apron 2, be convenient for laminate optical film 4 and display panel 1 on protection apron 2, the one end of fixed bolster 3 is fixed on display panel 1, and the another side is fixed on protection apron 2, and wherein, protective apron 2 is kept away from to the one side that fixed bolster 3 was fixed on display panel 1, and fixed bolster 3 is fixed at the one side of protection apron 2 towards display panel 1, fixes on the edge that protection apron 2 surpassed display panel 1 moreover. In addition, one of the attaching surfaces of the optical film 4 and the display panel 1 is a frosted surface, that is, in three cases, the attaching surface of the optical film 4 is a frosted surface, and the attaching surface of the display panel 1 is a smooth surface; the binding surface of the optical diaphragm 4 is a smooth surface, the binding surface of the display panel 1 is a frosted surface, and both the binding surfaces of the optical diaphragm 4 and the display panel 1 are frosted surfaces. Because the effect of water smoke is produced when two smooth surfaces are attached, Newton's rings are easily produced, and the optical film 4 with the frosted surface is attached between the protective cover plate 2 and the display screen, so that the optical film 4 and the display panel 1 are not in substantial contact, and the phenomenon of Newton's rings is avoided. In addition, due to the existence of the optical film 4, the phenomenon that the protective cover plate 2 and the display panel 1 are scratched during fitting is avoided. In addition, the optical film 4 is mainly located between the protective cover 2 and the display panel 1, and has the functions of preventing newton rings from being generated and the display panel 1 from being scratched, the optical film 4 itself can be used for filtering blue light, increasing the transmittance, and the like, and needs to have high light transmittance to prevent light from being transmitted, and has certain hardness and haze, the thickness of the frosted particles is preferably 0.35 to 0.45 μm (preferably 0.4 μm), and the diameter is 300 to 450nm (also preferably 375 nm).

The utility model provides a display screen, compared with the prior art, laminating optical film 4 between protective cover plate 2 and display panel 1, avoid protective cover plate 2 and the direct laminating of display panel 1 to produce the water smoke effect, produce the phenomenon of Newton's ring, in addition, the binding face of optical film 4 and one of the two of display panel 1 is the frosting, optical film 4's dull polish granule exists between display panel 1 and the protective cover plate 2, when making display panel 1 and dull polish optical film 4 contact, be non-substantial laminating, thereby the production of Newton's ring phenomenon has been avoided, in addition, protective cover plate 2 and display panel 1 have still been avoided producing the fish tail at the two in-process of laminating.

In the present embodiment, it is preferable that the optical film 4 is a frosted film, the cost of the optical film 4 is lower than that of the display panel 1, and in case of damage or other reasons causing replacement, the cost of replacing the optical film 4 is much lower than that of the display panel 1, and the replacement cost includes not only the price cost but also the time cost and labor cost of replacement, and therefore, the frosted optical film 4 is preferable. In the present embodiment, the protective cover plate 2 is a glass cover plate, the display panel 1 is liquid crystal glass, the fixing film is a frosted film with high light transmittance, and the selectable range of the adhesive material is relatively wide but the light transmittance cannot be affected.
