Description
Technical field
The present invention relates to technical field of liquid crystal display, particularly a kind of LCM liquid crystal displays module.
Background technology
LCM liquid crystal displays are fine and smooth with its image clearly, do not flash, do not hinder eye, radiationless, low-power consumption, more frivolous to wait many
Many advantages and instead of traditional CRT cathode-ray tube displays, enjoy consumers in general to favor.Current more application is in electronics
Table, mobile phone, PDA, handheld device, learning machine, GPS navigator, digital camera, digital code camera, computer monitor and
Television set etc..Medical in automobile, also there is application in the high reliability request field such as military affairs.Wherein preferable structure design and structure
Dress technology can preferably be protected liquid crystal display from the influence of external environment and be broken in daily use with more energy efficient
It is bad, it is that the life of product is played and energetically acted on very much, is that product accumulates more prestige and public praise.
At present, traditional liquid crystal display module LCM（Liquid Crystal Module）Generally comprise FOG liquid crystal displays
Screen 1, light guide plate 2, reflector plate 3, LB（Light-emitting section）4th, glue frame 5 and backboard 6,5 groups of light guide plate 2, reflector plate 3, LB4 and glue frame
Into backlight module, integrally-built assembling mode as shown in figure 1, but this structure product strength it is weaker, LCM is held by external force
The problems such as fragile screen or IC disconnected row, because the driving IC and backlight LB4 in LCDs 1 are the glue frames 5 that abut backlight module
What positive and negative was fitted together, when LCM persistently put brightness liquid crystal display screen driving IC and backlight LB4 all can while generate heat, because
It is PC materials for backlight glue frame 5, thermal conductivity factor is poor, it is difficult to heat be conducted, the stabilization worked long hours to product
There are very big influence in property and life-span.Backlight LB is assembled in the glue frame 5 of backlight, and because glue frame 5 is PC materials, product is persistently lighted
Or work in high temperature environments, glue frame 5 is easily deformed, and the bad phenomenons such as quick-fried lamp light leak often occurs to LCM liquid crystal display modes
Group visual effect has an impact；Influence the reliability of product.
The content of the invention
In view of the above-mentioned problems, the invention provides a kind of LCM liquid crystal displays module, being generated heat in LCDs and LB
When, the problem of heat can shedding in time, and solve broken screen improves product brightness, improves the reliability of product.
The technical solution adopted by the present invention is：
A kind of LCM liquid crystal displays module, including FOG LCDs and the backlight module located at the FOG LCDs back side,
The backlight module includes light guide plate, and the back side of light guide plate is provided with reflector plate, and the light inlet of light guide plate is provided with LB, backlight module
The back side has been provided with the metal backing of support protective effect, and the marginal position of metal backing is provided with the U-shaped lampshade being bent to form, reflection
Piece, light guide plate and LB are connected in U-shaped lampshade, and one layer of PET is additionally provided between the outer surface of FOG LCDs and U-shaped lampshade
Pad.
Preferably, FOG LCDs includes Cell, pol, IC and wiring board.
It is highly preferred that the wiring board is FPC or PCBA.
Compared with prior art, the beneficial effects of the present invention are：The present invention provides a kind of LCM liquid crystal displays module, will
Metal backing bending forms U-shaped lampshade, the utilization rate of the light of raising, and on the backlight module similarly configured, the brightness of product is carried
8% has been risen, the power consumption of product has been reduced, has saved cost, while improving the mechanical strength of whole product, has synchronously been solved brokenly
Screen, IC fractures, backlight LB and FOG driving IC heat dissipation problem.
