According to the structure, a reflecting strip on an original light guide plate can be omitted, the material cost is reduced, meanwhile, the reflecting strip does not need to be attached in the assembling process, the production efficiency is improved, and the machining difficulty is reduced.

Description

TECHNICAL FIELD

[0001] The utility model belongs to the technical field of liquid crystal television and accessories, in particular to a mounting structure of side -in type reflector. BACKGROUND

[0002] The structure of side -in type liquid crystal television is the composition of diaphragm plus light guide plate plus reflector, and the light guide plate and reflector are the key components of side -in type backlight, the function of light guide plate is to introduce the light emitted from LED light bar from the side and make light evenly scatter to the whole liquid crystal panel through its internal microstructure (such as dot design). The design of light guide plate directly influences the uniformity of screen brightness and energy consumption. The reflector is located below the light guide plate, and its function is to reflect the light scattered by the light guide plate back to the front of the screen, thereby enhancing the brightness of the screen.

[0003] At present, most of the light guide plates and reflector strips are installed by trimming the reflector strip to the appropriate length and using twice double -sided adhesive to paste, but due to the thickness limitation of the light guide plate, there is a problem of operation difficulty when the reflector strip is attached, and the efficiency is low. SUMMARY

[0004] Technical scheme: in order to solve the above technical problems, the utility model provides a mounting structure of side -in type reflector, specifically including light guide plate, reflector strip;The light guide plate is PMMA plate material with thickness d;The reflector strip is a three -edge folded groove structure, wherein the light guide plate is placed in the groove structure of the reflector strip, and the width of the fold is d.

[0005] As an improvement, wherein the area of the light guide plate is the same as the bottom area of the reflector strip groove structure, d is 1.5-2mm, and the light guide plate and the reflector strip are connected by pasting.

[0006] As an improvement, it further includes LED light bar, and the LED light bar is installed on the side of the light guide plate without the reflector strip.

[0007] Beneficial effect: compared with the conventional structure, the structure provided by the utility model can remove the use of the reflector strip on the original light guide plate, reduce the material cost, and improve the production efficiency and reduce the processing difficulty without attaching the reflector strip in the assembly process.

[0012] The specific embodiments of the present application will be further described in detail below with reference to the examples. The following examples are used to illustrate the present application, but not to limit the scope of the present application.

[0013] See Figs. 1-3 As shown in the figure, a mounting structure of a side-in type reflective sheet, comprising a light guide plate 1 and a reflective strip 2; the light guide plate 1 is a PMMA plate with a thickness d; the reflective strip 2 is a three-edge folded groove structure, wherein the light guide plate 1 is placed in the groove structure of the reflective strip 2, and the folded width is d.

[0014] The area of the light guide plate 1 is the same as the bottom area of the groove structure of the reflective strip 2, d is 1.5-2mm, and the light guide plate 1 is connected with the reflective strip 2 by pasting. The mounting structure further comprises an LED light bar, which is installed on the side of the light guide plate 1 without the reflective strip 2.

[0015] Working principle: the structure of the reflective sheet is modified, a circle of fold line is added to the three edges of the reflective sheet 3, the width of the fold line is equal to the thickness of the reflective sheet, the three edges of the reflective sheet 3 are folded to form a groove, and the light guide plate can be directly installed in the groove formed by the reflective sheet. When assembling, the reflective sheet is directly folded, then the light guide plate is placed, and the assembly is completed.

[0016] The structure can remove the reflective strip originally used on the light guide plate, reduces the material cost, does not need to attach the reflective strip during the assembly process, improves the production efficiency, and reduces the processing difficulty.

[0017] The above-described embodiments only express several embodiments of the present application, and the description is more specific and detailed, but it should not be understood as limiting the scope of the utility model patent. It should be noted that for ordinary skilled persons in the art, without departing from the concept of the present application, a number of modifications and improvements can be made, which all belong to the protection scope of the present application. Therefore, the protection scope of the utility model patent should be subject to the appended claims.
