Description
Technical field
This utility model relates to display device, particularly relates to a kind of backlight dress with incident curved surfaces in display device
Put.
Background technology
Backlight module is one of key part and component of panel of LCD, and function is well-off brightness and distribution
Uniform light source so that it is can normal show image.
The structure of general side entrance back module is the lamp source (generally CCFl or LED) after using the power on, and it passes through
There is the acrylic refraction leaded light of printing net-point, make uniform light be distributed in the surface of backlight module, utilize this principle, so that it may so that
Line source is converted to uniform area source.Again through the effect of diffusion sheet He other diaphragms, improve the brightness of area source further
With the uniformity, diffusion injection is distributed in light-emitting zone.
But, along with extensively application and the requirement of energy-saving and emission-reduction of LED technology, reduce Financial cost, reduce energy consumption
Cry is more and more higher so that how to reduce energy consumption and becomes problem demanding prompt solution.
Summary of the invention
In order to solve the problems of the prior art, this utility model provides the back of the body with incident curved surfaces that a kind of energy consumption is low
Electro-optical device.
This utility model provides a kind of back lighting device with incident curved surfaces, including light guide plate, lens subassembly and light source
Assembly, the side of described light guide plate is provided with groove, and described lens subassembly is arranged in described groove, and described lens subassembly is arranged on
Between described light guide plate, light source assembly, described light source assembly includes light source board and the light source being arranged on described light source board, described
Lens subassembly includes that reflection bar and lens, described light source are arranged in described lens, described reflection bar, light source board, light guide plate phase
Enclosing formation and seal cavity, described light source, lens are arranged in described annular seal space body, and described lens are provided with light source installation cavity
Body, described light source is arranged in described light source installation cavity body, be provided with in described light source installation cavity body two symmetrically arranged enter light
Curved surface, described lens are square, and described reflection bar is L-shaped.
The beneficial effects of the utility model are: by such scheme, can be improved the utilization of light by lens, reflection bar
Rate, is reducing energy consumption, is reducing cost.
