Specific implementation mode

The utility model is described in detail with reference to embodiment, embodiment is only the preferred reality of the utility model Mode is applied, is not the restriction to the utility model.

Incorporated by reference to Fig. 1 and Fig. 2, the utility model provides a kind of glass light guide plate 1, due to the light extraction of glass light guide plate 1 Face is relatively smooth, and the diaphragm on 1 light-emitting surface of glass light guide plate is easily absorbing on glass light guide plate 1, to cause film It wrinkles bad, the utility model is equipped with atomization diffusion coating 2, the atomization diffusion coating 2 in the light-emitting surface of the glass light guide plate 1 The transparent diffusion particle 22 mixed including clear dope 21 and with clear dope 21, mixed transparent diffusion particle 22 divide at random For cloth inside clear dope 21, part can also be formed in 21 surface of clear dope, and non-smooth surface is formed with this, when glass leaded light When 1 top attaching film of plate, diaphragm will not be adsorbed on glass light guide plate 1, can not only make light be uniformly distributed and can avoid by This film caused wrinkle is bad.Preferably, clear dope 21 can select to use transparent resin, transparent diffusion particle 22 that can select Use the transparent spherical little particle such as PC or PMMA.It should be noted that the proportioning of clear dope 21 and transparent diffusion particle 22 It is not construed as limiting, Non-smooth surface table can be formed by being equipped with a small amount of transparent diffusion particle 22 or a large amount of transparent diffusion particle 22 Face can achieve the effect that diaphragm is not adsorbed onto on glass light guide plate 1.

Since 1 all surface of glass light guide plate needs to keep smooth, there cannot be the structures such as small crack, groove, otherwise glass The intensity of glass light guide plate 1 can reduce, and therefore, polishing treatment is passed through on the surface of the glass light guide plate 1, to prevent glass light guide plate 1 there are small crack or groove, the intensity of reinforcing glass light guide plate 1.
