Referring to fig. 1-4, a backlight source 100 according to an embodiment of the disclosure includes a light emitter 140, a supporting frame 110, and an optical assembly 120.
The light emitter 140 is a light emitting component of the backlight 100, and the light emitter 140 is disposed at one side of the optical assembly 120. The illuminant 140 is generally an LED illuminant, which has the advantages of low heat generation, low energy consumption, and long life.
The optical assembly 120 is a main body of the backlight 100, and the optical assembly 120 can adjust the light emitted from the light emitting body 140, so as to provide the light to the display assembly 200. In the embodiment of the present invention, the optical assembly 120 includes a light guide plate 121, a diffusion sheet 122, and a brightness enhancement film, which are sequentially stacked in the support frame 110, and the support frame 110 can provide a peripheral protection for the optical assembly 120. The support frame 110 may be a rubber frame or an iron frame. Specifically, the light guide plate 121, the diffusion sheet 122, and the brightness enhancement film are stacked together to form a whole, which is fixed in the support frame 110.
The light emitting members 140 are disposed at the side of the light guide plate 121, and the light emitting members 140 project light into the light guide plate 121 through the side of the light guide plate 121, and after the light enters the light guide plate 121, the light is transmitted by the light guide plate 121 and finally enters the diffusion sheet 122 through the light guide plate 121. The diffuser 122 can diffuse the light, so that the light finally emitted from the optical assembly 120 is more uniform.
The brightness enhancement film optically processes the light passing through the diffuser 122 for brightness enhancement, and the incremental process is well known in the art and will not be described further herein. The brightness enhancement film typically includes a lower brightness enhancement film 123 and an upper brightness enhancement film 124 stacked in sequence. In this case, the light guide plate 121, the diffusion sheet 122, the lower brightness enhancement film 123, and the upper brightness enhancement film 124 are sequentially stacked in a space surrounded by the support frame 110.
In the embodiment of the present invention, the optical assembly 120 is provided with an avoiding hole a penetrating through the thickness direction thereof, a portion of the supporting frame 110 is located in the avoiding hole a, and a portion of the supporting frame 110 located in the avoiding hole a encloses a shooting hole B. The electronic device according to the embodiment of the present invention includes the camera 300, the camera 300 is disposed inside the display screen, and the camera 300 can perform shooting through the shooting hole B.
The backlight source 100 disclosed in the embodiment of the present invention may further include a light blocking band 150, a portion of the diffusion sheet 122 surrounding the avoiding hole a and facing away from the light emitter 140 may be regarded as a first portion, and a portion of the light guide plate 121 surrounding the avoiding hole a and facing away from the light emitter 140 may be regarded as a second portion. The light blocking band 150 is disposed between the first portion and the second portion. The light blocking band 150 can function as a light blocking.
In a specific assembling process, the light blocking tape 150 may be previously fixed on the diffusion sheet 122 and then stacked and assembled with the light guide plate 121 along with the diffusion sheet 122.
In a specific operation process of the backlight 100, light projected by the light emitter 140 may be totally reflected by a surface of the light guide plate 121 for forming the avoiding hole a, as shown by a dotted arrow in fig. 3, and the reflected light may cause a light leakage phenomenon. In the backlight 100 disclosed in the embodiment of the present invention, the light blocking strip 150 is disposed on the path of the totally reflected light, and the light (as shown by the solid arrow in fig. 3) totally reflected by the surface of the light guide plate 121 for forming the avoiding hole a is projected onto the light blocking strip 150, so as to avoid continuous emission of the light and avoid light leakage.
The backlight source 100 disclosed in the embodiment of the present invention improves the structure of the backlight source in the existing electronic device, by adding the light blocking band 150 between the portion of the diffusion sheet 122 surrounding the avoiding hole a and facing away from the light emitting body 140 and the portion of the light guide plate 121 surrounding the avoiding hole a and facing away from the light emitting body 140, the surface of the light guide plate 121 used for forming the avoiding hole a totally reflects the light entering the light guide plate 121, and the light blocking band 150 is located on the path of the reflected light, so that the reflected light can be blocked, the light can be prevented from being emitted out of the display screen, and the light leakage phenomenon generated by the light can be prevented.
In the embodiment of the present invention, the light blocking tape 150 may have a variety of types, and specifically, the light blocking tape 150 may be a light blocking ink layer (e.g., a black ink layer) or a reflective layer. The reflecting layer can reflect the light projected on the reflecting layer, and finally the light can be prevented from passing through the reflecting layer. Specifically, the reflective layer may be a silver plated layer, an aluminum plated layer, or the like.
Since the light guide plate 121 is used to form a region of the avoiding hole a, which is away from the light emitter 140, to perform total reflection on the light, light leakage is caused. Therefore, in a more preferable aspect, the light blocking tape 150 may extend along the edge of the avoidance hole a, and the width of the light blocking tape 150 may be gradually reduced in a direction away from the light emitter 140, thereby forming the structure as shown in fig. 4.

Specifically, the reflective film 125 is adhered to the light guide plate 121.
In the embodiment of the present invention, the avoiding hole a may be formed at an end of the optical assembly 120 away from the light emitter 140, in which case, the distance from the avoiding hole a to the light emitter 140 is larger, so as to reduce the adverse effect of the light emitter 140 on the avoiding hole a.

The light shielding tape 130 can shield the gap to prevent the gap from being exposed. The end surface of the top end of the support frame 110 refers to an end surface of the support frame 110 facing the light supplement direction of the backlight 100. In a more preferred embodiment, the width of the region where the light-shielding tape 130 is bonded to the brightness enhancement film is smaller than the width of the light-blocking tape 150, in which case the width of the light-blocking tape 150 is larger, which can achieve a better light-blocking effect.
In the case where the brightness enhancement film includes a lower brightness enhancement film 123 and an upper brightness enhancement film 124, a light-shielding tape 130 is attached to an edge of the upper brightness enhancement film 124.
