Abstract
The utility model relates to a liquid crystal module structure, comprising a liquid guide plate, a lamp tube component at one side of the liquid guide plate, and a reflecting cover covering the lamp tube component, wherein the periphery of the liquid guide plate is provided with a back plate clamped at back side and an adhesive frame clamped at front side for fitting the back plate to connecting and fixing the reflecting cover, the lamp tube component and the liquid guide plate integrally. The liquid crystal module structure is characterized in that the front end part of the reflecting cover is adhered with a film washer for avoiding sharp ends contacting and scraping the inner surface of the adhesive frame. The utility model attaches a film washer at the edge of the sharp end of the reflecting cover, thereby effectively avoiding sharp parts of the edges scraping the inner surface of the adhesive frame, to avoid detritus generation of the adhesive frame, confirm the uniformity of emergent light of the backlight module and improve product yield of the backlight module.
Description
Technical field:
The utility model relates to a kind of LCD backlight modular structure.
Background technology:
LCD because of have low diathermaneity, characteristics such as volume is compact and power consumption is low, be widely used in mobile phone, personal digital assistant, portable digital video disk player (Digital Video Disc, DVD), field such as mobile computer, personal computer and TV.Yet because display panels itself is not had a characteristics of luminescence, so must cooperate certain light source just can reach display effect, this provides the structure of light source to be the backlight liquid crystal display module.Existing LCD backlight modular structure is mainly become by Bu spare Group such as backboard, glue frame, light guide plate, fluorescent tube reflex housings, because the gap design surplus between each parts of module backlight is less and be subjected to the restriction of production technology, in module assembling process backlight, produce foreign matter because of the mutual scraping between parts often, particularly between the front side of reflex housing point and glue frame medial surface, contact the glue frame chip that scraping is produced, cause falls into the inside of module backlight, and has a strong impact on the image display effect of LCD.
Summary of the invention:
The purpose of this utility model is to provide a kind of LCD backlight modular structure, this back light module unit structure can effectively prevent module backlight in assembling process reflex housing to the scraping of its front side glue frame, thereby guarantee product quality.
The utility model LCD backlight modular structure, comprise light guide plate and be arranged on the fluorescent tube assembly of light guide plate one side and cover in the reflex housing of fluorescent tube assembly periphery, also be provided with the backboard that is buckled in its rear side on the described light guide plate perimembranous and be buckled in the connecting with backboard of its front side, it is characterized in that: be pasted with on the anterior end of described reflex housing to avoid its most advanced and sophisticated film rubber cushion of swiping that contacts with glue frame medial surface so that reflex housing, fluorescent tube assembly, light guide plate are connected fastening all-in-one-piece glue frame.
The utility model is because reflex housing is pasted with the film rubber cushion at most advanced and sophisticated edge part, thereby can effectively prevent of the scraping of its edge sharp portion to glue frame medial surface, avoid the generation of glue frame chip, help guaranteeing that module backlight goes out the product percent of pass of uniformity of light and raising module backlight.
Description of drawings:
Fig. 1 is the organigram of the utility model LCD backlight module;
Fig. 2 is the A-A sectional view (the utility model embodiment one) of Fig. 1;
Fig. 3 is the A-A sectional view (the utility model embodiment two) of Fig. 1.
Embodiment:
Fig. 2 is the diagrammatic cross-section of the utility model embodiment one; The utility model LCD backlight modular structure, comprise light guide plate 1 and be arranged on the fluorescent tube assembly 2 of light guide plate 1 one sides and cover in the reflex housing 3 of fluorescent tube assembly periphery, also be provided with the backboard 4 that is buckled in its rear side on light guide plate 1 perimembranous and be buckled in the connecting with backboard 4 of its front side, be pasted with on the anterior end of reflex housing 3 to avoid its most advanced and sophisticated film rubber cushion 6 of swiping that contacts with glue frame medial surface so that reflex housing 3, fluorescent tube assembly 2, light guide plate 1 are connected fastening all-in-one-piece glue frame 5; The edge part 7 of this film rubber cushion extends beyond the edge 8 at reflex housing tip.
Fig. 3 is the diagrammatic cross-section of the utility model embodiment two; The utility model LCD backlight modular structure, comprise light guide plate 1 and be arranged on the fluorescent tube assembly 2 of light guide plate 1 one sides and cover in the reflex housing 3 of fluorescent tube assembly periphery, also be provided with the backboard 4 that is buckled in its rear side on light guide plate 1 perimembranous and be buckled in the connecting with backboard 4 of its front side, be pasted with on the anterior end of reflex housing 3 to avoid its most advanced and sophisticated film rubber cushion 6 of swiping that contacts with glue frame medial surface so that reflex housing 3, fluorescent tube assembly 2, light guide plate 1 are connected fastening all-in-one-piece glue frame 5; The edge part 7 of this film rubber cushion extends beyond the edge 8 at reflex housing tip, exceeds the edge that part 7 bendings envelope the reflex housing tip.
One side of the film rubber cushion of the foregoing description one and embodiment two can glued joint fixed lamp tube assembly 2, and the film rubber cushion is a heat resistant adhesive tape.
Remarkable advantage of the present utility model in sum: the one, can effectively prevent of the scraping of reflex housing edge sharp portion to glue frame medial surface, avoid the generation of glue frame chip, help guaranteeing that module backlight goes out the product percent of pass of uniformity of light and raising module backlight.The 2nd, improved simple in structure, easy to operate, can not increase any extra cost.
