The following description will be mainly made of the glue strings 4 located on the three sides of the top side 11, the left side 12 and the right side 13 of the display device.
In some embodiments, the plastic frame 4 is a plastic frame 4, and the material of the plastic frame 4 is a composite material formed by adding 10% Glass Fiber (GF for short) into a PC, and the color of the plastic frame 4 is, for example, white or white gray, which is not particularly limited in this embodiment.
As shown in fig. 2, the rubber frame 4 is correspondingly located at the edge of the optical film 3. Specifically, the plastic frame 4 is supported between the optical film 3 and the light-homogenizing plate 5, and is used for limiting the distance between the optical film 3 and the light-homogenizing plate 5, so as to improve the utilization rate of the optical film 3 on the light emitted by the light-homogenizing plate 5.

As shown in fig. 2, the frame 4 extends from the edge of the display device toward the center of the display device, wherein the supporting portion 41 of the frame 4 has an oblique angle structure, i.e. the supporting portion 41 extends more inward than the first side 4111 of the light guiding surface 411, and the supporting portion 41 extends shorter inward than the second side 4112 of the light guiding surface 411, such that the light guiding surface 411 of the supporting portion 41 is formed in an outward inclined manner from the first side 4111 to the second side 4112.
The light guiding surface 411 is inclined outwards from one side corresponding to the light homogenizing plate 5 to one side corresponding to the optical film 3, and the light guiding surface 411 has a light guiding effect in the light emitting direction of the light, so that the light emitted from the edge part of the light homogenizing plate 5 can be further diffused towards the edge of the optical film 3, the light coverage range of the light entering the optical film 3 can be increased, the light emitting area of the optical film 3 is increased, and the area range of the effective display image of the display panel 1 can be increased.
In general, the glue frame 4 extends into the position of the light homogenizing plate 5, which is located in the display area 1a of the display panel 1, so that the light emitting area of the light homogenizing plate 5 is blocked, and the glue frame 4 can shield the display of the edge of the display area 1a of the display panel 1, so that the black edge phenomenon occurs at the edge of the display area 1a, and the display effect of the narrow frame of the display panel 1 is affected.
In this embodiment, the side wall of the support portion 41 of the glue frame 4 is set to be in the form of the light guide surface 411, the first side 4111 of the light guide surface 411 corresponds to the light homogenizing plate 5, the second side 4112 corresponds to the optical film 3, and the light guide surface 411 is inclined from the first side 4111 to the second side 4112 towards the edge of the optical film 3, so that the light emitted from the edge of the light homogenizing plate 5 is diffused towards the edge of the optical film 3, the light emitting area of the optical film 3 can be increased, further, the display of the edge of the display area 1a of the display panel 1 blocked by the glue frame 4 can be avoided, the black edge phenomenon at the edge of the display area 1a can be prevented, and the narrow frame display effect of the display panel 1 can be improved.
In some embodiments, the first side 4111 of the light guiding surface 411 is located in the display area 1 a; the second side 4112 of the light guiding surface 411 is located in the non-display area 1b, or the second side 4112 of the light guiding surface 411 is located in the display area 1a and a distance between the second side 4112 and a boundary of the display area 1a is less than 0.5mm.
The first side 4111 of the light guiding surface 411 is located in the display area 1a of the display device, and a sufficient overlap width is provided between the support portion 41 of the glue frame 4 and the light homogenizing plate 5, so as to ensure that the glue frame 4 can fix the light homogenizing plate 5 firmly, so that the phenomenon that the light homogenizing plate 5 shakes or deviates from the original position in the moving process of the display device is avoided.
The second side 4112 of the light guiding surface 411 is located in the non-display area 1b of the display device, and the second side 4112 of the light guiding surface 411 is completely free from shielding the portion of the optical film 3 located in the display area 1a, so that the display effect of the display area 1a of the display panel 1 is completely free from being affected.
Alternatively, the second side 4112 of the light guiding surface 411 may slightly enter the display area 1a of the display panel 1, that is, the second side 4112 of the light guiding surface 411 shields the optical film 3 by a slight distance corresponding to the display area 1a, so that the light emitted from the light homogenizing plate 5 can still diverge towards the edge of the optical film 3, and the display effect on the edge of the display area 1a of the display panel 1 is less affected.
In order that the second side 4112 of the light guiding surface 411 does not significantly affect the display effect of the edge of the display area 1a, a distance between the second side 4112 of the light guiding surface 411 and a boundary of the display area 1a is less than 0.5mm, that is, a width of the second side 4112 of the light guiding surface 411 extending into the display area 1a is less than 0.5mm.
In some embodiments, a distance between the first side 4111 of the light guiding surface 411 and a boundary of the display area 1a is less than 2.5mm. Thus, the first side 4111 of the light guiding surface 411 can avoid excessively large width covering the light homogenizing plate 5, and the effect of diffusing the light at the edge of the light homogenizing plate 5 to the edge of the optical film 3 is affected, so as not to affect the display effect at the edge of the display area 1a of the display panel 1.
In some embodiments, the included angle between the light guiding surface 411 of the supporting portion 41 of the bezel 4 and the optical film 3 is less than or equal to 45 °. In this way, the light guiding surface 411 is inclined from the first side 4111 to the second side 4112 to the edge of the optical film 3 to a greater extent, and on the basis that the first side 4111 of the light guiding surface 411 covers the light-equalizing plate 5 with a certain width, the second side 4112 of the light guiding surface 411 covers the edge of the optical film 3 with a shorter width, so that the light emitting area of the optical film 3 can be increased.
Therefore, the light guiding effect of the light guiding surface 411 can be further improved, and the light emitted from the edge of the light homogenizing plate 5 can be further diffused to the edge of the optical film 3, so that the influence of the glue frame 4 on the display effect of the edge of the display area 1a of the display panel 1 is effectively reduced, and the display effect of the narrow frame of the display panel 1 is further improved.
In addition, in one possible embodiment, the gap between the light homogenizing plate 5 and the optical film 3 is greater than or equal to 2.5mm. That is, the thickness of the supporting portion 41 is greater than or equal to 2.5mm, so that a sufficient gap between the light-homogenizing plate 5 and the optical film 3 can be ensured, and the utilization rate of the outgoing light of the light-homogenizing plate 5 by the optical film 3 can be improved.
To a certain extent, by increasing the gap between the light-equalizing plate 5 and the optical film 3, the diffusion distance of the outgoing light at the edge of the light-equalizing plate 5 to the edge of the optical film 3 can be increased, and further, the influence of the glue frame 4 on the display effect of the display panel 1 due to the covering of the display area 1a of the light-equalizing plate 5 can be further reduced.
In addition, it should be noted that, in the present embodiment, the light guiding surface 411 of the glue frame 4 is configured to incline from the first side 4111 to the second side 4112 toward the edge of the optical film 3, so that the problem that the glue frame 4 stretches into the display area 1a to cause the black edge phenomenon can be effectively solved.
Meanwhile, the overlap joint width between the glue frame 4 and the light homogenizing plate 5 is correspondingly increased, so that the width of the light homogenizing plate 5 can be correspondingly reduced on the basis of ensuring that the light homogenizing plate 5 and the glue frame 4 have enough overlap joint width, the distance between the light homogenizing plate 5 and the edge of the back plate 8 is increased, and enough expansion gaps are reserved between the side wall of the light homogenizing plate 5 and the edge of the back plate 8.
Because the expansion gap of the light homogenizing plate 5 is increased, enough expansion amount is reserved for the light homogenizing plate 5, the light homogenizing plate 5 of the embodiment can be a common light guide plate made of an acrylic plate or a PC plate, and a glass light guide plate which is not expanded when heated is not needed, so that the width of a frame on the front side of the display device can be reduced, the appearance is improved, and the product competitiveness is improved.
