In addition, as shown in fig. 2, one side of the buffer material 30 facing the light guide plate 20 has a reflective surface 31 capable of reflecting light, or, as shown in fig. 3 and 4, the buffer material 30 includes a body 33 and a reflective sheet 34, the reflective surface 31 is formed on the reflective sheet 34, wherein the body 33 is fixedly disposed on the housing 10, and the reflective sheet 34 is fixedly disposed on the side of the body 33 facing the light guide plate 20; alternatively, the reflective sheet 34 is fixedly disposed on the outer periphery of the light guide plate 20 different from the light incident side 22.
The reflector 34 can be selectively fixed on the side of the main body 33 facing the light guide plate 20, so that the reflector 34 is adhered to the housing 10 through the main body 33, and the reflector 34 can be prepared with the housing 10 in the manufacturing process, thereby reducing the working hours; or, the reflective sheet 34 can be selectively and fixedly disposed on the outer periphery of the light guide plate 20 different from the light incident side 22, and the reflective sheet 34 can be further and fixedly disposed on the side of the body 33 facing the light guide plate 20, so that the body 33 is adhered to the light guide plate 20 through the reflective sheet 34, and when the reflective sheet 34 needs to be repaired and replaced, the light guide plate 20 with lower material cost can be replaced at the same time, thereby reducing the heavy labor cost.
In addition, as shown in fig. 2 to 4, the buffer material 30 protrudes from a side opposite to the light guide plate 20 to form a positioning portion 35, and the positioning portion 35 abuts against the housing 10 and is located at the periphery of the display panel 60, so as to limit the movement of the display panel 60 on a plane, thereby improving the stability of the display panel 60, furthermore, the main body 33 of the buffer material 30 can be formed by a rubber block or a foam material, in addition, as shown in fig. 2 and 3, the buffer material 30 can further form a receiving portion 37 by recessing from the side opposite to the light guide plate 20, the housing 10 is embedded in the receiving portion 37, the receiving portion 37 can abut against the housing 10, thereby effectively improving the stability of the buffer material 30 disposed in the housing 10, and since the receiving portion 37 of the buffer material 30 is disposed at the other side of the buffer material 30 opposite to the positioning portion 35, the housing 10 can simultaneously provide the supporting effect of the positioning portion 35, the positioning part 35 is not easy to be turned outwards due to the expansion of the display panel 60, and the positioning effect of the positioning part 35 is further improved; in addition, the surface of the housing 10 and the surface of the buffer material 30 are coplanar, so that the subsequent mounting operation is convenient.
For example, if the body 33 of the buffer material 30 is made of rubber, the rubber can be adapted to the periphery of the light guide plate 20, as shown in fig. 3, when the light guide plate 20 is rectangular, the rubber with a suitable length can be taken according to the length of three sides of the light guide plate 20, as shown in fig. 5, when the light guide plate is irregular, the rubber adapted to the length of the sides of the light guide plate 20 can be arranged around the periphery of the light guide plate 20. If the main body 33 of the cushioning material 30 is formed of a foam material, the foam material is filled to fix the light guide plate 20 so as to be adapted to the space between the light guide plate 20 and the housing 10.
