The light guide plate 20 has a light exit surface 21 and a light entrance side 22. The light exit surface 21 is located on the front side of the light guide plate 20, and the light incident side 22 is located on one side of the light exit surface 21 of the light guide plate 20.

As shown in FIGS. 1 to 3, the buffer material 30 is disposed between the housing 10 and the light guide plate 20, and the buffer material 30 is located on the outer periphery of the light guide plate 20 different from the light incident side 22, The buffer material 30 has a reflective surface 31 facing the light guide plate 20, and the front side of the buffer material 30 forms a bearing portion 32. The thermal expansion degree of the buffer material 30 is less than the thermal expansion degree of the light guide plate 20. 30 is divided into multiple segments and arranged around the periphery of the light guide plate 20.

As shown in FIG. 3, the plurality of optical films 40 are arranged in front of the light emitting surface 21 of the light guide plate 20.

As shown in FIG. 4, the light source 50 is arranged on the light incident side 22 of the light guide plate 20.

As shown in FIG. 1, FIG. 2 or FIG. 3, the display panel 60 is carried on the supporting portion 32 of the buffer material 30 and is located in front of the plurality of optical films 40, or the display panel 60 and all the optical films 40 The optical film 40 is simultaneously supported by the supporting portion 32.

In addition, as shown in FIG. 2, the buffer material 30 has a reflective surface 31 that can reflect light toward one side of the light guide plate 20, or, as shown in FIGS. 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 main body 33 is fixed to the housing 10, and the reflective sheet 34 is fixed to the main body 33 facing the light guide plate 20 Or, the reflective sheet 34 is fixed on the outer periphery of the light guide plate 20 different from the light incident side 22.

The reflective sheet 34 can optionally be fixed on the side of the main body 33 facing the light guide plate 20, thereby allowing the reflective sheet 34 to pass through the main body 33 and be adhered to the housing 10. During the production process, the reflective sheet 34 can be attached The housing 10 is ready to be manufactured at the same time, thereby reducing the working hours; or, the reflective sheet 34 can also be selectively fixed on the outer periphery of the light guide plate 20 different from the light incident side 22, and the reflective sheet 34 can It is further fixed on the side of the main body 33 facing the light guide plate 20, so that the main body 33 is fixed on the light guide plate 20 through the reflective sheet 34. When the reflective sheet 34 needs to be repaired and replaced, the cost of materials can be lower. The light guide plate 20 is replaced at the same time, thereby reducing heavy labor costs.

In addition, as shown in FIGS. 2 to 4, the buffer material 30 protrudes to form a positioning portion 35 on the side facing away from the light guide plate 20, and the positioning portion 35 abuts against the housing 10 and is located on the display panel 60 The periphery can restrict the movement of the display panel 60 on the plane to improve the stability of the display panel 60. Furthermore, the body 33 of the buffer material 30 can be formed of rubber blocks or foamed materials. In addition, As shown in Figures 2 and 3, the buffer material 30 can be further recessed to form an accommodating portion 37 on the side facing away from the light guide plate 20. The housing 10 is embedded in the accommodating portion 37. The accommodating portion 37 can be attached to the housing 10, which can effectively improve the stability of the cushioning material 30 disposed in the housing 10, and because the accommodating portion 37 of the cushioning material 30 is disposed on the cushioning material 30 relative to the positioning portion On the other side of 35, the housing 10 can provide the supporting effect of the positioning portion 35 at the same time, so that the positioning portion 35 is not easily turned over due to the expansion of the display panel 60, and the positioning of the positioning portion 35 is further improved. Effect; In addition, the surface of the housing 10 and the buffer material 30 are coplanar, which is convenient for subsequent installation operations.

For example, if a rubber block is selected for the body 33 of the buffer material 30, the rubber block can be adapted to the outer periphery of the light guide plate 20, as shown in FIG. 3, when the light guide plate 20 is rectangular, it can be arranged according to the guide The three sides of the light plate 20 are made of rubber blocks of appropriate length. As shown in FIG. 5, when the light guide plate 20 is of irregular shape or non-rectangular polygon, it can be rubber that is suitable for the side length of the light guide plate 20. The blocks are arranged around the periphery of the light guide plate 20. In addition, if the body 33 of the buffer material 30 is formed of foamed material, the space between the light guide plate 20 and the housing 10 can be adapted to fill the foamed material to fix the light guide plate 20. More preferably, the display of the present invention further includes an adhesive layer 36, which is disposed between the carrying portion 32 and the display panel 60, and is used to limit the displacement of the light guide plate 20, which can reduce collisions and The effect of the abnormal sound.

The degree of thermal expansion is less than the degree of thermal expansion of the light guide plate 20, and it is more elastic than the buffer material 30, so it can provide cushioning effects in different directions to effectively prevent the light guide plate 20 from moving or thermally expanding relative to the housing 10 And other issues.

As shown in Figures 3 and 4, when the display is in use, the buffer material 30 facing the reflective surface 31 of the light guide plate 20 can provide light reflection, thereby improving the overall backlight effect of the display. The buffer material 30 surrounds the outer periphery of the light guide plate 20 different from the light incident side 22. Therefore, when the display is reflected by the reflective surface 31 of the same material, the light guide plate 20 is different from the light incident side 22. The light reflection effect at the outer periphery is consistent, which can effectively avoid the obvious difference between light and darkness when light is reflected, thereby improving the optical taste and the picture presentation quality of the display.

Furthermore, as shown in FIG. 3, the carrying portion 32 of the buffer material 30 can carry the display panel 60, and at the same time, the positioning portion 35 can provide the positioning effect of the display panel 60, so there is no need to The housing 10 is additionally provided with a bearing member for bearing the display panel 60, which can further achieve the effect of saving material cost.

In summary, the display of the present invention can be set in various shapes according to requirements, and the buffer material 30 is provided at the outer periphery of the light guide plate 20 different from the light incident side 22 to provide the light guide plate 20 in different directions. At the same time, the buffer material 30 provides a consistent light reflection effect, which can effectively avoid the obvious difference in light and darkness during light reflection, thereby improving the display quality of the display. In addition, the buffer material 30 The carrying portion 32 can carry the display panel 60, so there is no need to additionally provide a carrying member for carrying the display panel 60 at the housing 10, which can further achieve the effect of saving material cost.
