Specific implementation mode
For that can further appreciate that the feature, technological means and the specific purposes reached, function of the utility model, below
The utility model is described in further detail with specific implementation mode in conjunction with attached drawing.
Referring to figs. 1 to Fig. 3.
The utility model embodiment discloses a kind of glass light guide plate without dark angle, including glass plate 10, and glass plate 10 is equipped with
At least one side incidence surface 11 and a light-emitting surface 12, when the utility model glass light guide plate is applied to side entrance back module,
It at least needs to be equipped with a side light source, thus at least needs there are one matching side incidence surface 11, the length of side incidence surface 11
Degree is less than the length or width of glass plate 10, and the one side opposite with light-emitting surface 12 is the back side 13 in glass plate 10, and the back side 13 is equipped with
At least two corners of light directing site layer 131, the back side 13 are equipped with frosted structure 132, and frosted structure 132 is located at 11 liang of side incidence surface
On the back side 13 outside end.
When the utility model glass light guide plate is applied to side entrance back module, linear light source is set to side incidence surface 11,
The size of linear light source is matched with side incidence surface 11, and light enters glass plate 10 from side incidence surface 11, and light directing site layer 13 changes line
The light path of source light, makes light be emitted from light-emitting surface 12, and frosted structure 132 is spread uniform light by diffusing reflection, it is ensured that
Brightness at frosted structure 132 improves the brightness of 10 corner of glass plate.
The utility model carries out frosted processing to the corner at the back side 13 of light guide plate, forms the projection position of frosted structure 132
In the both ends of side incidence surface 11, frosted structure 132 can carry out diffusing reflection to light, to improve the bright of glass light guide plate corner
