The lateral entrance type backlight module adopts a light bar as a light source, the light bar is arranged at the edge of the side face of the backlight module, and the light guide plate is matched to conduct the light emitted from the side face to the front face for emitting through the conduction of the light guide plate to the light.

The utility model discloses when adopting side income formula backlight unit, as shown in fig. 7, can also set up reflector plate 14 in one side that the light guide plate deviates from the plain noodles, optical film 12 of light guide plate light-emitting side can bond each other with the light guide plate through setting up the bond line 13 that goes out the plain noodles upper fringe region at the light guide plate, and the same is true, when backlight unit sets up a plurality of optical film, also can adopt bond line 13 to bond each other between a plurality of optical film, thereby can make optical film not through other mechanical parts snap-on the light guide plate, avoid installing the space that the part occupies the frame region.
Since the light source is disposed at one side of the light guide plate 11a, in order not to affect the normal incidence of the light source light into the light guide plate, the adhesive layer 13 is not disposed at the edge region of the side where the light source is disposed on the light exit surface of the light guide plate, and in order to ensure that the optical film 12 and the light exit surface of the light guide plate 11a can be firmly bonded, as shown in fig. 8, the edge regions of the light guide plate 11a and the adjacent optical film 12 at the other sides except the side where the light source l is disposed are all bonded to each other by the adhesive layer 13.

| lighting at normal temperature | Conventional ageing | Accelerated test | Others | |
| The membrane is not adhered | Deformation of diaphragm | - | - | The diaphragm collapses under its own weight |
| Patch top side adhesive | Qualified | Membrane wrinkle | Membrane wrinkle | The diaphragm contracts and jumps out of the left and right middle frames |
| Left and right sides of the diaphragm are pasted | Qualified | Membrane wrinkle | Membrane wrinkle | The diaphragm contracts and jumps out of the middle frame of the upper side |
| The left and right sides of the diaphragm are pasted | Qualified | Qualified | Qualified | Qualified |
When the optical film is only placed on the light emergent surface of the light guide plate and is not adhered in any area, the optical film is deformed in a normal-temperature lighting state, and the film is collapsed under the action of self gravity. When the bonding layer is arranged on the edge area of the side edge of the optical film opposite to the light source (namely, the upper table is used for describing the day side), the optical film is normally lightened at normal temperature, but the optical film is wrinkled in an aging test and an acceleration test, and due to the shrinkage of the optical film, the optical film can jump out of the middle frame of the two side edges (namely, the left side and the right side) adjacent to the side edge where the light source is located. When the bonding layers are arranged on the side edge areas of two sides (namely, the left side and the right side on the upper table) of the optical film adjacent to the side where the light source is located, the optical film is normally lightened at normal temperature, but the optical film is wrinkled in an aging test and an acceleration test, and due to the shrinkage of the optical film, the optical film jumps out of the middle frame of the side edge (namely, the upper side) opposite to the light source. And only when the bonding layers are arranged on the other three sides except the side where the light source is located, the test results of the mutual links of normal-temperature lighting, conventional aging and accelerated tests meet the requirements. Therefore, in the embodiment of the present invention, the bonding layer is disposed at the edge region of other three sides except the side where the light source is located, and the adjacent optical films and the light guide plate are bonded and fixed by the bonding layer.
The light guide plate has a light transmission effect based on the total reflection principle, and after the adhesive layer 13 is disposed on the light exit side surface of the light guide plate 11a, the total reflection phenomenon on the surface of the light guide plate at the adhering position is destroyed, and the light propagation track is changed, so that the light exits, and a bright edge is formed. Through experimental comparison and verification, the color of the adhesive tape bonding surface on the surface of the light guide plate has a large influence on the electrical performance, and fig. 9 shows a luminous flux distribution diagram of the light emitting side of the backlight module when the adhesive layer 13 is not arranged; when the adhesive layer is disposed on the light-emitting surface of the light guide plate 11a and the white adhesive is disposed facing the light guide plate 11a, the light flux distribution on the light-emitting side of the backlight module is as shown in fig. 10; when the adhesive layer is disposed on the light-emitting surface of the light guide plate 11a and the black adhesive is disposed facing the light guide plate 11a, the light flux distribution on the light-emitting side of the backlight module is as shown in fig. 11. The luminance curves of the backlight module under the three conditions are shown in fig. 12, wherein the abscissa represents the distance from the light guide plate to the light incident surface, and the ordinate represents the luminance; as can be seen from fig. 12, when the white adhesive is disposed on the light-emitting surface of the light guide plate, the brightness of the light-emitting side is greater than that when the white adhesive is disposed on the light-emitting surface of the light guide plate.
In order to reduce the influence of arranging a bonding layer on the light-emitting surface of the light guide plate on total reflection and conduction of light rays in the light guide plate as much as possible, the embodiment of the utility model adopts a white bonding agent on one side facing the light guide plate in the bonding layer in the edge area of the side opposite to the light-entering side of the light guide plate; and the bonding layers in the edge areas of the two side edges adjacent to the light incident side of the light guide plate adopt black bonding agents on the side facing the light guide plate.
Because light is generally conducted in the direction from the surface of the incident side of the light to the opposite side of the incident side of the light, if a large amount of light leaks from the opposite side of the incident side of the light, the brightness of the light-emitting side is reduced integrally, and the electrical performance indexes such as brightness and electrical performance are affected. The utility model discloses go out the bonding layer of the marginal position department on the surface relative one side with the light source with the light guide plate and adopt white binder towards the binder of light guide plate one side, during white binder can reflect the light of incident back to the light guide plate to a certain extent, reduce revealing of this side light. And for the side edge of the two adjacent sides of the light side to have relatively weak light conduction effect, and in order to avoid the occurrence of bright edges on the two side edges, the adhesive on the light-emitting surface of the light guide plate, which is positioned at the edge positions of the two adjacent sides of the light source and faces the side of the light guide plate, can adopt a black adhesive. Therefore, the reflection of light from the two side edges is reduced, and the generation of bright edges is prevented.
In order to reduce the influence of the adhesive layer on the light transmission on the side opposite to the light source and to avoid the occurrence of a wide bright edge due to the increase in the amount of light emitted by the adhesive layer on that side, the width s1 of the adhesive layer on the light exit surface of the light guide plate on the side opposite to the light source is set to be 1.2mm or less. Meanwhile, in order to prevent brightness from occurring at both side edges adjacent to the light source and to prevent the optical film from jumping out at both side edges, the width s2 of the adhesive layer on the light exit surface of the light guide plate at both sides adjacent to the light source is set to be less than or equal to 1.5 mm.

As shown in fig. 13, in the direct type backlight module, light sources (usually, light emitting diodes) are uniformly arranged on a back plate, and in order to uniformly transmit light emitted from the light sources to a display panel, a diffusion plate 11b and a series of optical films 12 need to be provided on the light emitting side of the light sources. The direct type backlight module can set different backlight subareas to independently emit light respectively, theoretically, each light source can independently emit light to control the brightness, and therefore dynamic dimming of the display panel can be achieved. The diffusion plate in the direct type backlight module is fixed on the light-emitting side of the light source through a plurality of support columns, and a certain distance is reserved between the diffusion plate and the light source, so that the light source can fully mix light. A reflector plate 14 may also be provided on the side of the light source facing away from the diffuser plate. The embodiment of the utility model provides a can bond optical film each other with the diffusion piece through the bond line, and similarly, when backlight unit sets up a plurality of optical film, also can adopt bond line 13 to bond each other between a plurality of optical film to can make optical film not through other mechanical parts snap-on the diffuser plate, avoid installing the space that the part occupy the frame region.
The direct type backlight module has a function of homogenizing the light emitted from the light source, and the bonding layers 13 may be disposed at the edge regions of the four sides of the diffusion plate, and the top view structure of the direct type backlight module is shown in fig. 14, so that the optical films disposed on the diffusion plate can be tightly bonded to the diffusion plate at the four edges. When the backlight module comprises a plurality of optical films, adjacent optical films can be bonded through the adhesive layer in each edge area. This ensures that the optical film can be stably fixed to the diffuser plate.
Because the direct-type backlight module arranges the light source on the back plate, the width of the bonding layers at the four sides can be consistent, for example, less than 1.5 mm. The setting of bond line inevitably can lead to reducing at the light outgoing volume that sets up the position of bond line simultaneously, the embodiment of the utility model provides a can set up the binder towards diffuser plate one side into white binder, strengthen the reflection of incidenting the light on the white binder from this, this part reflection light can be reflected to one side of diffuser plate once more by reflector plate 14, improves the utilization ratio of light to a certain extent.
