Abstract
The utility model relates to a side incidence type light guide plate, which comprises a light transmission surface and a backlight surface. The light transmission surface of the light guide plate is provided with a light guide point array. The side incidence type light guide plate is characterized in that the light guide point array consists of light guide points depressed in or protruding out of the light transmission surface of the light guide plate, and the diameters of the light guide points gradually decrease from the incidence side to the other side of the light guide plate. The utility model has the advantages that the light uniformity and brightness of the light guide plate are enhanced.
Description
Technical field
The utility model relates to mobile phone light guide panel, relates in particular to the high light conducting plate structure of a kind of light extraction efficiency.
Background technology
Existing light guide plate can be provided with dot matrix for increasing light extraction efficiency on the native country of light guide plate, by dot matrix, can improve luminescence efficiency, but existing dot matrix is onesize, and the dot matrix of this spline structure still can not reach best bright dipping and strengthen effect.
The utility model content
The utility model provides a kind of side incident type light guide plate at the above-mentioned defective of prior art, to strengthen light extraction efficiency.
In order to solve the problems of the technologies described above, the utility model is achieved through the following technical solutions:
A kind of side incident type light guide plate, this light guide plate comprises exiting surface and shady face, exiting surface in light guide plate is provided with the leaded light dot matrix, it is characterized in that, described leaded light dot matrix is formed by the leaded light point that is recessed into or protrudes from the light guide plate exiting surface, and the diameter from light guide plate light inlet side to the described leaded light point of opposite side from large to small.
As can be seen from the above technical solutions, the utility model is designed to the leaded light dot matrix from large to small, can improve the light extraction efficiency of light guide plate thus, strengthens the uniformity coefficient and the briliancy of light guide plate bright dipping.
Description of drawings
Accompanying drawing 1 is the utility model structural representation.
Embodiment
Below in conjunction with embodiment the utility model is described in further detail.
Shown in accompanying drawing, side incident type light guide plate, this light guide plate 1 comprises exiting surface 10 and shady face, exiting surface 10 in light guide plate is provided with leaded light dot matrix 11, described leaded light dot matrix is formed by the leaded light point that is recessed into or protrudes from the light guide plate exiting surface, and the diameter from light guide plate light inlet side to the described leaded light point of opposite side from large to small.
Above-mentioned specific embodiment is purpose, feature and the effect that is used for describing in detail the utility model, for the personage who is familiar with this type of skill, according to the above description, may do part change and modification to this specific embodiment, its essence does not detach the spiritual category person of the utility model, all should be included in the claim of this case suitable first Chen Ming.
