Embodiment
Below in conjunction with drawings and Examples, embodiment of the present utility model is described in further detail.Following examples for illustration of the utility model, but are not used for limiting scope of the present utility model.
In description of the present utility model, it will be appreciated that, term " middle part ", " on ", D score, "front", "rear", " vertically ", " level ", " top ", " end " " interior ", the orientation of the instruction such as " outward " or position relationship be based on orientation shown in the drawings or position relationship, only the utility model and simplified characterization for convenience of description, instead of the device of instruction or hint indication or element must have specific orientation, with specific azimuth configuration and operation, therefore can not be interpreted as restriction of the present utility model.
In description of the present utility model, it should be noted that, unless otherwise clearly defined and limited, term " installation ", " being connected ", " connection " should be interpreted broadly, and such as, can be fixedly connected with, also can be removably connect, or connect integratedly; Can be mechanical connection, also can be electrical connection; Can be directly be connected, also indirectly can be connected by intermediary, can be the connection of two element internals.For the ordinary skill in the art, concrete condition the concrete meaning of above-mentioned term in the utility model can be understood.
As shown in Figures 2 and 3, the novel narrow frame backlight structure that the utility model provides comprises glue frame, backboard, reflector plate, light guide plate and blooming piece, reflector plate, light guide plate and blooming piece are successively set on backboard from bottom to top, glue frame is arranged on the side of light guide plate and blooming piece, light guide plate is provided with the reference column raised up near the position of side, with fixed optics diaphragm, blooming piece offers the pilot hole matched with reference column.
In above-described embodiment, owing to being provided with the reference column raised up near the position of side in light guide plate, blooming piece offers the pilot hole matched with reference column, the pilot hole of blooming piece is enclosed within the reference column of light guide plate, thus make blooming piece relative with light guide plate fixing, avoid the generation of the light guide plate scuffing phenomenon that in traditional design, between blooming piece and light guide plate, relative displacement causes, simultaneously, due to blooming piece edge not bamboo product ear, correspondingly, glue frame can carry out the design of narrow frame, strengthens the aesthetic measure of liquid crystal indicator.
Further, the inner side of glue frame has projection, pillar groove is offered below this projection, the top of reference column is stretched in pillar groove, by the design of projection coordinated with reference column, can prevent blooming piece from taking off from location column length, improve the reliability of light guide plate and optical diaphragm structure.
Preferably, reference column is transparent supporting columns, reference column and light guide plate integrated injection molding, and such reference column is easy to process, and reference column is not fragile yet.Blooming piece is fixed in light guide plate, and passes through the transparent supporting columns of the pillar groove lightguide plate fixing of projection on glue frame, prevent blooming piece from coming off.
Usually, light guide plate all arranges reference column near the position of short side, just blooming piece can be fixed by the less reference column of magnitude setting like this, arrange conveniently, also do not affect the performance of function in the middle part of light guide plate.
Above-mentioned reference column structure can be designed to different structure according to actual conditions, and as considered processing complexity, producing line assembling operability etc., preferably, as shown in Figure 5, Figure 6, reference column is cylindrical or elliptical cylinder-shape; Certainly as shown in Fig. 7, reference column is also the rectangle of band chamfering.The shape machine-shaping of above-mentioned reference column is simple and convenient, and it is comparatively strong to produce line assembling operability, and the edge of reference column to pilot hole can be avoided to cause draw splitting by setting that is circular, oval or chamfering.
Usually, blooming piece comprises the diffusion sheet, prismatic lens and the increment film that set gradually from the bottom to top.
The liquid crystal indicator that the utility model provides on the other hand comprises above-mentioned novel narrow frame backlight structure, adopt the liquid crystal indicator of above-mentioned novel narrow frame backlight structure, because blooming piece is relative with light guide plate fixing, avoid the generation of the light guide plate scuffing phenomenon that in traditional design, between blooming piece and light guide plate, relative displacement causes, simultaneously, due to blooming piece edge not bamboo product ear, correspondingly, the design that glue frame can carry out narrow frame significantly reduces the width of liquid crystal indicator, its contrast effect as shown in Figure 4, greatly can increase aesthetic measure like this, glue width of frame d wherein in the utility model is much smaller than glue width of frame D of the prior art.
In sum, in the novel narrow frame backlight structure that the utility model provides and liquid crystal indicator, by the design of pilot hole on reference column in light guide plate and blooming piece, make blooming piece relative with light guide plate fixing, avoid the generation of the light guide plate scuffing phenomenon that in traditional design, between blooming piece and light guide plate, relative displacement causes, and glue frame can be made can to carry out the design of narrow frame, strengthen the aesthetic measure of liquid crystal indicator.
Below be only preferred implementation of the present utility model; it should be pointed out that for those skilled in the art, under the prerequisite not departing from the utility model know-why; can also make some improvement and modification, these improve and modification also should be considered as protection domain of the present utility model.
