Problems solved by technology

[0005] However, there are at least the following problems in the prior art: due to the removal of the metal back plate, the light emitted from the light guide plate 21 passes through the plastic frame 1 to the outer surface of the plastic frame 1 and is reflected by the lower surface of the touch substrate 5 . into the array substrate 3, and then reflected by the metal wires 31 on the array substrate 3, and finally emitted through the black matrix opening 41 (such as figure 1 (indicated by the middle arrow), which is seen by the human eye, which will cause light leakage in the product

Embodiment 1

[0031] Please refer to figure 2 and image 3 This embodiment provides a plastic frame 1, including a plastic frame body 11 and reflective crystals 12 distributed in the plastic frame body 11, and the reflective crystals 12 are used to reflect light emitted from a light guide plate.

[0032] From figure 2 It can be seen from the figure that a plurality of reflective crystals 12 are distributed in the plastic frame body 11. The reason why the reflective crystals 12 are provided is to reflect the light emitted from the light guide plate on the reflective crystals 12, so that part of the light leaks downward, and the other A part of the light is weakened by the atomized cut surface of the reflective crystal 12 during reflection, so as to prevent the light from directly emitting from the upper part and the left side of the plastic frame 1, thereby avoiding light leakage of the display device.

[0033] Wherein, the reflective crystal 12 is made of optical fiber.

[0034] The re...

Embodiment 2

[0043] Please refer to Figure 4 , this embodiment provides a method for preparing a plastic frame, including:

[0044] Step 101 , forming a reflective crystal 12 .

[0045] In this embodiment, the reflective crystal 12 is formed by laser cutting. Because laser cutting will generate a lot of heat, the side 121 of the reflective crystal 12 will be atomized at high temperature. Therefore, when the light is totally reflected inside the reflective crystal 12, it will be The atomized side 121 reduces the intensity, that is, the side 121 can reduce the intensity of the light.

[0046] Step 102, mixing the reflective crystal 12 into the main body material of the plastic frame.

[0047] Step 103 , injection molding the material of the plastic frame body to form the plastic frame body 11 including the reflective crystal 12 .

[0048] The method for preparing the plastic frame in this embodiment is used to prepare the plastic frame in Example 1. For specific description, please refer...

Embodiment 3

[0051] Please refer to Figure 5 , the present embodiment provides a backlight module 2, including a light guide plate 21, a light shielding tape 22 and a plastic frame 1; the light guide plate 21 is located on one side of the plastic frame 1, and the light shielding tape 22 is located above the plastic frame 1; The frame body 11 and the reflective crystals 12 distributed in the plastic frame body 11, the reflective crystals 12 are used for total reflection of the light emitted from the light guide plate 21, so that the totally reflected light passes from the plastic frame 1 to a side of the light guide plate 21 Side and the side of the glue frame 1 away from the side of the light-shielding adhesive tape 22 shoot out.

[0052] From Figure 5It can be seen from the figure that when the light is emitted from the light guide plate 21 to the plastic frame 1, a part of the light is reflected by the reflective crystal 12 distributed in the plastic frame body 11 to the side of the p...

Abstract

The invention provides a rubber frame, a manufacturing method thereof, a backlight module and a display device and belongs to the technical field of display. The problem that existing touch products without metal back plates leak light can be solved. The rubber frame comprises a rubber frame body and reflection crystals distributed in the rubber frame body. The reflection crystals are used for reflecting light emitted by a light guide plate.

Description

technical field [0001] The invention belongs to the field of display technology, and in particular relates to a plastic frame and a preparation method thereof, a backlight module and a display device. Background technique [0002] With the continuous update of touch products, touch products have gradually developed towards thinner, brighter, lower power consumption and higher reliability. [0003] Please refer to figure 1 , the structure of the touch product mainly includes a plastic frame 1, a light guide plate 21, a light-shielding tape 22, an array substrate 3, a color filter substrate 4, and a touch substrate 5, wherein the array substrate 3 includes a first substrate 30 and is located on the first substrate. The metal wiring 31 on the bottom 30 , the color filter substrate 4 includes a second substrate 40 and a black matrix 41 on the second substrate 40 . [0004] However, in order to realize the thinning of the product, the metal backplane in the traditional touch pr...
