Abstract
The utility model discloses a side-light-type light guide plate used for a backlight module. The backlight module is formed by a reflection plate, the light guide plate and an optical template set which are sequentially connected. The left side and the right side of the backlight module are fixed through a rubber frame and a back plate respectively. An LED lamp source set is arranged in front of the light incoming face of the light guide plate. The face, close to the reflection plate, of the light guide plate is an inclined face and is parallel to the reflection plate. The diameter of each net point is increased, the distribution density of the net points is increased, and round spots produced due to the increased net points are avoided. Meanwhile, due to the fact that the density is increased, the coverage rate of oil ink is increased, the oil ink can cover flaws of the light guide plate, and accordingly the masking performance of the backlight module for the flaws is improved, the yield of the backlight module is improved, and the rejection rate of the light guide plate is reduced. Additionally, light is emitted from the side of the light guide plate, the light can be uniformly emitted from the upper side face of the light guide plate, and due to the light source emitting the light from the side of the light guide plate, the light guide plate has the remarkable advantages of being light, thin and low in electricity consumption and having narrowed frames.
Description
Technical field
The utility model relates to photoelectric field, relates in particular to a kind of side-light type module LGP backlight.
Background technology
In the prior art, the light utilization efficiency of LGP is low, and 60% light loss consumption is in transmission course, and the light loss consumption is too big, is unfavorable for energy-conservation.
Important accessory and brightness source that backlight shows as LCD, extremely important concerning improving liquid crystal display brightness, therefore, people attempt multiple mode and remove to improve the LCD display brightness from the backlight aspect, at first from lamp source angle, can increase the fluorescent tube number, increase the lamp source power, but can cause all that power consumption is big, volume strengthens; Secondly from the LGP angle, this material to LGP, design have proposed very high requirement.
The utility model content
The technical problems to be solved in the utility model has been to provide the side-light type of a kind of light utilization efficiency height, thin thickness module LGP backlight.
For solving the problems of the technologies described above, the utility model is realized by following scheme: a kind of side-light type module LGP backlight, and module backlight is connected in turn by reflecting plate, LGP, optics matrix group, and the left and right sides is fixed by glue frame, backboard respectively;
Described LGP incidence surface dead ahead is provided with LED lamp source group;
Described LGP is an inclined-plane in the one side near reflecting plate, and this inclined-plane is parallel with reflecting plate.
Further, the employed material of described LGP is optical grade acryl sheet material.
Further, distribute on the described LGP various densitys, reflection site not of uniform size.
Further, the minimum dot area density in described reflection site is between 12%～30%.
Further, described reflector net is put whole dot density between 30%～48%.
Further, described reflection site minimum diameter is between 0.3～0.5mm.
The utility model has the advantages that: adopt the diameter that increases the site, the density of arranging that reaches the increase site, the Dapple that produces to avoid the site to strengthen; Simultaneously, the increase in density then coverage rate of printing ink increases, and printing ink can be covered the LGP flaw, thereby improves backlight module to the covering property of flaw, to promote the yield of backlight module, reduces the scrappage of LGP.In addition, the side light inlet penetrates luminous energy uniformly from the exiting surface of upper side, and therefore, the light source design of its side incident has the remarkable advantage of light weight, slim, narrow frameization, low power consumption.
Description of drawings
