Abstract
The invention discloses a liquid crystal display module, comprising a backlight module, a liquid crystal display module, and a connecting piece. The liquid crystal display module is characterized in that the backlight module comprises a backboard, a reflector plate, a light guide plate, an optical film, a first side plate, and a backlight. The backboard is provided with two bulges which hold out against the reflector plate between the backboard and the reflector plate. A first cavity is formed between the backboard and the reflector plate. The bottom surface of the first cavity is provided with an auxiliary backlight which directly faces the reflector plate. Through arranging the auxiliary backlight, light beams are projected from the lower part of the reflector plate, the number of light beam sources is increased, diffuse reflection or refraction effect is indirectly improved, so as to obtain good refraction or diffuse reflection effect. In addition, because of the design of the auxiliary backlight, when one of the backlight and the auxiliary backlight is damaged, a user can still manage to view with an effort, and repairs the liquid crystal display module in another day.

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, provide enough light beam sources, and make once one of them is damaged because of auxiliary backlight source, user still can continue viewing reluctantly, another day keeps in repair.
For solving the problem, technical scheme of the present invention is: a kind of liquid crystal display module, comprise backlight module, the liquid crystal display module just right with described backlight module, connect the web member of described backlight module and described liquid crystal display module, its innovative point is: described liquid crystal display module comprises display panels and diffuse reflector, described backlight module comprises backboard, be arranged on the reflector plate above described backboard, be arranged on the light guide plate above described reflector plate, be arranged at the blooming piece above described light guide plate, be arranged at these light guide plate both sides and first side plate connected vertically with described backboard, be arranged on the backlight on described side plate, described blooming piece and described display panels just right, described backlight be arranged on light guide plate side and with described light guide plate same level height, described backboard between described backboard and described reflector plate is provided with the projection that two are withstood described reflector plate, between described backboard and described reflector plate, forms the first cavity, the bottom surface of this first cavity is provided with just to the auxiliary backlight source of described reflector plate.
Preferably, described auxiliary backlight source is diversity backlight.
Preferably, described projection is circular cone structure.
Preferably, described projection is transparence structure.
Preferably, described web member is two groups and is separately positioned on the left web member of described backlight assembly and liquid crystal display module both sides and the right web member consistent with described left connecting-piece structure, described left web member and described right web member are symmetrical arranged, described left web member comprises header board, the second side plate and rear plate, described second side plate is vertical with described front and rear panels respectively, described former board part is pressed together on described diffuse reflector, and described rear plate portion is pressed together on described backlight assembly.
Preferably, described header board and described first side sheet room are provided with contiguous block, and described header board and described first side sheet room form the second cavity, and described contiguous block is transparence structure.
The invention has the advantages that: below reflector plate, carry out beam projection by arranging auxiliary backlight source, thus improve the quantity in light beam source, indirectly improve diffuse reflection or refraction effect, thus obtain good refraction or diffuse effect.In addition because the design in auxiliary backlight source, make one of them breakage in backlight and auxiliary backlight source, user still can continue viewing reluctantly, another day keeps in repair.
