As shown in fig. 1, the present invention discloses a light guide plate 100, comprising: a light guide substrate 110, a protective film 120, and a reflective-side adhesive film 130.
As shown in fig. 1, the protective film 120 is attached on the light emitting surface 111 and the backlight surface 112 of the light guide substrate 110. The protective film 120 protects the light guide substrate 110, and prevents the light guide substrate 110 from being worn during transportation and storage.
As shown in fig. 1, the light guide substrate 110 includes a PC layer 113 and a PMMA layer 114 attached to each other, wherein the light emitting surface 111 is on the PMMA layer 114, and the backlight surface 112 is on the PC layer 113. The PC layer 113 and the PMMA layer 114 are bonded into a whole through a co-extrusion molding process, so that the light guide substrate 110 obtains the characteristics of high transmittance and scratch resistance of the PMMA layer 114, and meanwhile, the light guide substrate 110 also obtains the characteristics of strong toughness and high temperature resistance of the PC layer 113.
As shown in fig. 3, the backlight surface 112 is thermo-compressed with a plurality of astigmatic dots 115. The light rays are reflected by the light scattering dots 115 at different angles on the backlight surface 112, so that the light rays are scattered, and the light on the light emitting surface 111 is more uniform. As shown in fig. 2, the light emitting surface 111 is provided with a plurality of light guiding ribs 116. The light is further diffused by the light guide ribs 116, thereby further increasing the uniformity of the emitted light.
As shown in fig. 2, at least one side surface of the light guide substrate 110 is a light incident surface 117, at least one side surface of the light guide substrate 110 is a light reflecting surface 118, and the light incident surface 117 and the light reflecting surface 118 are not overlapped. The reflecting surface 118 is coated with a reflecting side film 130. The reflective-side adhesive film 130 is adhered to the reflective surface 118 by an adhesive layer (not shown).
As shown in fig. 1, in a preferred embodiment, a plurality of light guiding ribs 116 are arranged in parallel in sequence.
As shown in fig. 10, in a preferred embodiment, a plurality of light guiding ribs 116 are sequentially arranged in parallel at intervals.
As shown in fig. 7, the light guide rib 116 has a triangular cross section as a preferred embodiment.
As shown in fig. 1, the light guide rib 116 has a semicircular cross section as a preferred embodiment.
As shown in fig. 3, as a preferred embodiment, the light scattering dots 115 are thermocompression dots. The light scattering dots 115 are volcano-typed hot-pressing dots.
As shown in fig. 4, the present invention further discloses a side-in type backlight module 200, which includes a light guide plate 100.

When the light guide plate 100 is assembled to the side-entry backlight module 200, the protective films 120 attached to the light emitting surface 111 and the backlight surface 112 of the light guide substrate 110 need to be torn off. That is, the light guide plate 100 assembled on the side-in type backlight module 200 does not have the protective film 120, and the protective film 120 only temporarily protects the light guide plate 100. Namely, the light guide plate 100 is protected from the finished light guide plate 100 to the assembly of the light guide plate 100 to the side-in backlight module 200. When the light guide plate 100 is assembled to the side-in type backlight module 200, the light guide plate 100 is not protected by the protection film 120.
As shown in fig. 4, the number of the optical films 300 is two, and the two optical films 300 are sequentially stacked. The thickness of the optical film 300 is 0.15mm to 0.3 mm. Due to the limitation of the production process, the optical film 300 with the thickness of 0.15 mm-0.3 mm has the lowest production cost. When the thickness of the optical film 300 is between 0.15mm and 0.3mm, the brightness of the backlight module is affected by the excessive number of the optical films 300. If there is only one optical film 300, it is difficult to shield the defect on the light guide plate 100. The flaws on the light guide plate 100 are usually small white dots, small black dots, dot patterns and other scratched patterns on the light guide plate 100. By arranging the two optical films 300, on one hand, light rays are well diffused, so that the backlight module emits light uniformly; on the other hand, the flaw covering effect is good; on the other hand, the light-emitting brightness of the backlight module is not influenced.
As shown in fig. 5, the present invention further discloses a display device 10, which includes a side-in type backlight module 200, a light source 600 and a fixing frame 700.
