Description
Technical field
The utility model relates to field of electronic display, particularly a kind of two-sided back light structure.
Background technology
Backlight module function is as the well-off brightness of display unit and the light source that is evenly distributed, can normal show image.Now a lot of product needed double-sided display, the alarm display system of such as equipment, the display with double faces of information desk, now needing to provide in one can the two-sided back light structure of lighting at two sides; During in order to coordinate alarm display system, also need multiple color to distinguish.
Utility model content
The purpose of this utility model is to provide a kind of two-sided back light structure that can send different colours, energy lighting at two sides.
For achieving the above object, the utility model provides a kind of two-sided back light structure, comprise light guide plate and the luminescence unit being located at catheter plate side, described light guide plate comprises the first optical waveguide layer, the second optical waveguide layer and is located at the glue shell insulating course between the first optical waveguide layer and the second optical waveguide layer.
Preferably, described first optical waveguide layer comprises the first reflective surface being located at described glue shell insulating course side, the first exiting surface be oppositely arranged with the first reflective surface and be located at the first incidence surface of luminescence unit side; Described second optical waveguide layer comprises the second reflective surface being located at described glue shell insulating course side, the second exiting surface be oppositely arranged with the second reflective surface and be located at the second incidence surface of luminescence unit side; First and second reflective surface described is provided with optical microstructures.
Preferably, described luminescence unit comprises several polychromatic light source, and each polychromatic light source at least can send the light of 2 kinds of different colours.
The beneficial effects of the utility model: two-sided back light structure of the present utility model carries out luminescence by polychromatic light source, different colors can be shown as required, the facilities of described light guide plate, utilize glue shell insulating course by light guide plate function division, the not coplanar bright dipping of the same side light inlet, meets the needs of display product double-sided display.
In order to further understand feature of the present utility model and technology contents, refer to following about detailed description of the present utility model and accompanying drawing, but accompanying drawing only provide reference and explanation use, is not used for being limited the utility model.
Accompanying drawing explanation
Below in conjunction with accompanying drawing, by describing in detail detailed description of the invention of the present utility model, will make the technical solution of the utility model and other beneficial effect apparent.
In accompanying drawing,
Fig. 1 is the profile of two-sided back light structure of the present utility model.
Detailed description of the invention
For further setting forth the technological means and effect thereof that the utility model takes, be described in detail below in conjunction with preferred embodiment of the present utility model and accompanying drawing thereof.
Refer to Fig. 1, the utility model provides a kind of two-sided back light structure, comprise light guide plate 10 and the luminescence unit 20 being located at catheter plate 10 side, described light guide plate 10 comprises the first optical waveguide layer 12, second optical waveguide layer 14 and is located at the glue shell insulating course 16 between the first optical waveguide layer 12 and the second optical waveguide layer 14.
Described first optical waveguide layer 12 comprises the first reflective surface 122 being located at described glue shell insulating course 16 side, the first exiting surface 124 be oppositely arranged with the first reflective surface 122 and be located at the first incidence surface 126 of luminescence unit 20 side; Described second optical waveguide layer 14 comprises the second reflective surface 142 being located at described glue shell insulating course 16 side, the second exiting surface 144 be oppositely arranged with the second reflective surface 142 and be located at the second incidence surface 146 of luminescence unit 20 side; First and second reflective surface 122,142 described is provided with optical microstructures (not shown), and described luminescence unit 20 comprises several polychromatic light source 22, and each polychromatic light source 22 at least can send the light of 2 kinds of different colours.
In two-sided back light structure of the present utility model, luminescence unit 20 sends light, enter first and second optical waveguide layer 12,14 respectively from first and second incidence surface 126,146, light is uniform respectively after the optical microstructures process of first and second reflective surface 122,142 to be penetrated by first and second exiting surface 124,144.Two sides simultaneously can be luminous, and by the function that can realize double-sided display in a display device, polychromatic light source 22 can meet the demand of colorful display simultaneously.
In sum, two-sided back light structure of the present utility model carries out luminescence by polychromatic light source, different colors can be shown as required, the facilities of described light guide plate, utilize glue shell insulating course by light guide plate function division, the not coplanar bright dipping of the same side light inlet, meets the needs of display product double-sided display.
The above; for the person of ordinary skill of the art; can make other various corresponding change and distortion according to the technical solution of the utility model and technical conceive, and all these change and be out of shape the protection domain that all should belong to the utility model claim.
