Abstract
The invention discloses a high concentration photovoltaic liquid crystal display module. The high concentration photovoltaic liquid crystal display module comprises a backlight module, a liquid crystal display module arranged above the backlight module and a connecting piece which connects the liquid crystal display module and the backlight module. The high concentration photovoltaic liquid crystal display module is characterized in that the backlight module comprises a substrate, a reflector plate, a light guide plate, an optical film and a first backlight source, wherein the light guide plate and the first backlight source are located at the same horizontal height, the light guide plate is arranged obliquely relative to the horizontal plane, a second backlight source is arranged on the substrate, and the light beam direction of the second backlight source is perpendicular to that of the light guide plate. By arranging the light guide plate obliquely relative to the horizontal plane, when a light beam emitted by the first backlight source which is located at the same horizontal height with the light guide plate passes through the light guide plate, oblique and upward refract light or bounce light is generated, and meanwhile by means of another light beam generated by the second backlight source arranged on the substrate, the refraction effect or diffuse reflection effect is improved.
Description
Technical field
The present invention relates to a kind of liquid crystal display module, particularly relate to a kind of high light-focusing type liquid crystal display module.
Background technology
Liquid crystal indicator has that fuselage is thin, power saving, the many merits such as radiationless, be widely used.Liquid crystal indicator major part on existing market is backlight liquid crystal indicator, and it comprises liquid crystal panel and backlight module.The principle of work of liquid crystal panel places liquid crystal molecule in the middle of the glass substrate that two panels is parallel, there is the tiny electric wire of many vertical and levels in the middle of two panels glass substrate, change direction by whether being energized to control liquid crystal molecule, the light refraction of backlight module is out produced picture.Because liquid crystal panel itself is not luminous, need the light source provided by backlight module to carry out normal show image, therefore, backlight module becomes the pass of liquid crystal indicator
One of key asembly.And existing backlight module utilizes a backlight being arranged on a side to carry out direct projection, then reflector plate is utilized to carry out refraction or the diffuse reflection of light, but actual use can find because light beam source itself is limited, cause the later stage through diffuse reflector refraction or irreflexive poor effect, and once backlight breaks down, just cannot watch image quality, thus use and have inconvenience more.
Summary of the invention
The object of the present invention is to provide a kind of liquid crystal display module, there is the feature of high optically focused.
For solving the problem, technical scheme of the present invention is: a kind of high light-focusing type liquid crystal display module, comprise backlight assembly, be arranged on the liquid crystal display module above described backlight assembly, connect the web member of described liquid crystal display module and described backlight assembly, its innovative point is: described backlight assembly comprises substrate, reflector plate, light guide plate, blooming piece, with the first backlight of described light guide plate same level height, described light guide plate and horizontal plane are arranged, described substrate is provided with the second backlight, the beam direction of this second backlight is vertical with described light guide plate.
Preferably, the angle of described light guide plate and surface level is 5 ~ 10 degree.
Preferably, the angle of described light guide plate and surface level is 8 degree.
Preferably, described liquid crystal display module comprises display panels and is arranged on the diffuse reflector above described display panels, and described diffuse reflector is the globoidal structure of evagination.
Preferably, described diffuse reflector is made up of the globoidal structure of several evagination and several plane.
The invention has the advantages that: by light guide plate and horizontal plane are arranged, thus the light beam sent when the first backlight with light guide plate same level height produces a refract light tilted upward through light guide plate or diffuses, produce another light beam by the second backlight be arranged on substantially simultaneously, thus improve refraction or diffuse effect.
Accompanying drawing explanation
Below in conjunction with the drawings and specific embodiments, the present invention is further detailed explanation.
Fig. 1 is the structural representation of a kind of high light-focusing type liquid crystal display module of the present invention.
In figure: 1-backlight assembly, 11-substrate, 12-reflector plate, 13-light guide plate, 14-blooming piece, 15-first backlight, 16-second backlight, 2-liquid crystal display module, 21-display panels, 22-diffuse reflector, 3-web member.
Embodiment
High light-focusing type liquid crystal display module of the present invention comprises backlight assembly 1, is arranged on the web member 3 of liquid crystal display module 2, connection liquid crystal display module 2 and backlight assembly 1 above backlight assembly 1, its innovative point is: backlight assembly 1 comprise substrate 11, reflector plate 12, light guide plate 13, blooming piece 14, with the first backlight 15 of light guide plate 13 same level height, light guide plate 13 and horizontal plane are arranged, substrate 11 is provided with the second backlight 16, the beam direction of this second backlight 16 is vertical with light guide plate 13.By light guide plate 13 and horizontal plane are arranged, thus produce a refract light tilted upward when the light beam that the first backlight 15 with light guide plate 13 same level height sends is through light guide plate 13 or diffuses, produce another light beam by the second backlight 16 be arranged on substantially simultaneously, thus improve refraction or diffuse effect.
In order to obtain good refraction or diffuse effect, light guide plate 13 is 5 ~ 10 degree with the angle of surface level.And when light guide plate 13 is 8 degree with the angle of surface level, refraction effect or diffuse effect reach best.
The diffuse reflector 22 that above-mentioned liquid crystal display module 2 comprises display panels 21 and is arranged on above display panels 21, diffuse reflector 22 is the globoidal structure of evagination, not shown on figure, wherein, diffuse reflector 22 is made up of the globoidal structure of several evagination and several plane.By adopting above-mentioned structure, improve refraction or diffuse effect further, thus the image quality that user is seen within the scope of larger viewing is consistent, further control distortion degree.
Above, for the person of ordinary skill of the art, other various corresponding change and distortion can be made according to technical scheme of the present invention and technical conceive, and all these change and be out of shape the protection domain that all should belong to the claims in the present invention.
