A plurality of side surfaces between the front surface and the back surface of the light guide plate 100 may be set as the light incident side surface 110. The light bar 200 is arranged at the outer side of the edge of the light guide plate 100, and the light emitting surface of the light bar 200 is perpendicular to the light incident side surface 110 of the light guide plate 100, in the embodiment, the surface of the light emitted by the light bar 200 is used as the light emitting surface, and the light emitted by the center of the light emitting bead 220 on the light bar 200 is perpendicular to the light emitting surface, so that the central light of the light emitting bead 220 on the light bar 200 is parallel to the light incident side surface 110. The reflecting portion 300 is located on the outer side of the light incident side surface 110 of the light guide plate 100 and above the reflecting portion 300, the light emitting bead 220 of the light bar 200 emits light toward the reflecting surface of the reflecting portion 300, and the light emitted by the light bar 200 is reflected to the light incident side surface 110 of the light guide plate 100 through the reflecting surface of the reflecting portion 300. The light bar 200 is disposed at the outer side of the edge of the light guide plate 100, and the light emitting surface of the light bar 200 is perpendicular to the light incident side surface 110 of the light guide plate 100, so that the emitted light is reflected to the light incident side surface 110 of the light guide plate 100 through the reflecting surface of the reflecting part 300, and is emitted back light through the front surface of the light guide plate 100, thereby providing a light source for the liquid crystal panel. And the back of the lamp body of this structure sets up towards display device's backplate, only need directly set up the inboard back at lamp strip 200 with the back, and need not like lamp strip 200 among the prior art needs attached the installation on the framework side, the back has bigger installation region for display device's back, and there is sufficient space in the inboard back of big installation region for the adjustment after the lamp strip installation, be convenient for the installation and the dismantlement of lamp strip, and the inboard back need guarantee to have sufficient support intensity when the shaping, it warp for a short time when its shaping, the slope condition when lamp strip is installed just can fine improvement, therefore, it makes the assembly simpler to install the lamp strip on the back. And need not additionally to add protruding cushion on lamp strip 200, reduce lamp strip 200 cost, it is more convenient to make. And the light path length in the scheme that light goes into the light directly than traditional side income formula through reflection, makes mixed light distance long, makes the light of deriving through light guide plate 100 more even, and the leaded light effect is better.
As shown in fig. 2, in the present embodiment, the light bar 200 includes a light bar plate 210, the light-emitting beads 220 are mounted on the light bar plate 210, and the back surface of the light bar plate 210 is parallel to the back surface of the light guide plate 100. The light-emitting lamp bead 220 is an LED lamp bead, the effective light-emitting angle of the LED lamp bead is 0-180 °, as shown in fig. 3, the effective light-emitting angle of the light-emitting lamp bead 220 in this embodiment is 120 °, and by adopting the effective light-emitting angle, uniform light emission at a large angle can be realized, and the emitted light is convenient for light mixing in the light guide plate 100, so that the light guide effect is good. The reflection part 300 and the light guide plate 100 are located on the same plane, in a specific structure, the upper end of the reflection part 300 is flush with the light emitting surface of the light guide plate 100, and the lower end of the reflection part 300 is flush with the back surface of the light guide plate 100; thus, light rays are emitted from the LED lamp beads, strike the reflection portion 300, change most or all of the light paths through the reflection portion 300, and are reflected to the light incident side 110 of the light guide plate 100 to enter the light guide plate 100. The reflection part 300 located on the same plane as the light guide plate 100 can fully cover the light incident side surface 110, and reflect light as much as possible, so that light can be fully incident into the light guide plate 100, and the light energy utilization rate is improved.
The focus in this configuration is the design of the reflective portion 300, which is intended to guide more light into the light guide plate 100. Therefore, high reflectivity materials and proper profile design are important. The reflective portion 300 in this embodiment uses a material having a high reflectance and has a small light absorption rate. Specifically, the material with a reflectivity of more than 98% is manufactured into the required reflection part 300 by an integral molding process, so that the reflectivity of the reflection surface of the reflection part 300 to the light reaches more than 98%. The reflective surface of the reflective portion 300 may be a coated mirror having a high reflectance, for example, a material such as specular silver (reflectance 95%). Therefore, the reflectance of the reflecting surface in this embodiment is required to be more than 95%.
The reflection part 300 in the present embodiment mainly includes a front surface flush with the front surface of the light guide plate 100, a side surface opposite to the light incident side surface 110 of the light guide plate 100, and a light reflection surface facing the light incident side surface 110 of the light guide plate 100. The following embodiments of the reflective portion 300 are provided according to the different contour of the reflective surface of the reflective portion 300, but not limited thereto.
As shown in fig. 3, in the first structure, the reflecting surface includes an inclined surface 310, and a distance from the inclined surface 310 to the light incident side surface 110 gradually increases in a direction toward the light bar 200. That is, the end of the inclined surface 310 facing the front surface of the light guide plate 100 is disposed close to the light incident side surface 110, and the end facing the back surface of the light guide plate 100 is disposed far from the light incident side surface 110. Through this mode, when light from the light emitting surface outgoing of lamp plate, hit on inclined plane 310, light path can change through inclined plane 310 reflection back, makes light inject into the income light side as much as possible, and then gets into light guide plate 100 in, realizes the function of being shaded.
In this embodiment, one end of the inclined surface 310 is connected to the light guide plate 100, and the other end is connected to the light bar 200. This can block the light emitting direction, and prevent the light from leaking from the connection between the light guide plate 100 and the reflection part 300 or the connection between the reflection part 300 and the light bar 200. The inclined plane 310 and the light incident side surface 110 of the light guide plate 100 form an included angle theta not greater than 30 degrees, and by adopting the included angle theta, when the effective light emitting angle of the light emitting lamp bead 220 is 120 degrees, light is guided to the direction of the light incident side surface of the light guide plate 100 by the inclined plane 310 as much as possible. The efficiency of light entering the light incidence side is improved, and the light guide effect is improved.
In a second configuration, as shown in FIG. 4, the reflective surface includes a sloped surface 310 and a vertical surface 320. The distance from the inclined surface 310 to the light incident side surface 110 gradually increases in a direction toward the light bar 200. That is, the end of the inclined surface 310 facing the front surface of the light guide plate 100 is disposed close to the light incident side surface 110, and the end facing the back surface of the light guide plate 100 is disposed far from the light incident side surface 110. The vertical surface 320 is disposed parallel to the light incident side surface 110. One end of the inclined surface 310 is connected to the light guide plate 100, and the other end is connected to the vertical surface 320. The end of the vertical surface 320 facing away from the inclined surface 310 is connected to the light bar 200.
The reflecting surface in this structure adopts the design with inclined plane 310 and the 320 combination of perpendicular face, can be more effective with the light reflection that lamp strip 200 sent to light guide plate 100 in, through set up perpendicular face 320 on reflecting part 300 to make reflecting part 300 towards lamp strip 200's surface energy stable connection lamp strip 200 or center, thereby guarantee the stability of assembly. The reflecting portion 300 forming the reflecting surface of the combined structure is designed by combining a rectangular structure portion 330 and a triangular structure portion 340. The surface of the rectangular structure 330 facing the light incident side can reflect the effective light outside the light-emitting bead 220 to the light guide plate 100, and in addition, a part of light is reflected again through the surface of the triangular structure 340 facing the light incident side. The effective light rays inside the light-emitting lamp beads 220 can enter the light guide plate 100 after being reflected by the triangular structure parts 340 towards the surface of the light-entering side face or directly enter the light guide plate 100.
In the third configuration, as shown in fig. 5, the reflecting surface is a circular arc surface 350. The specific arc surface 350 includes a local circular arc surface, or a local elliptical arc surface, etc., taking a quarter of the circular arc surface as an example, the advantage of this design is that the perpendicular line of the reflection point passes through the center of the circular arc surface, and the center of the circular arc surface is placed at one side of the light-emitting lamp bead 220 close to the light guide plate 100, that is, at the position close to the light incident side surface 110 of the light guide plate 100. The light emitted by the light-emitting lamp beads 220 can easily reach the light-incident side 110, so that the light can be conveniently guided into the light guide plate 100.
In this structure arc surface 350 deviates from the direction indent setting of income light side 110, the one end of arc surface 350 is connected on light guide plate 100, and the other end is connected on lamp strip 200. Therefore, a light emitting space is formed between the reflecting surface of the arc surface 350 and the light incident side surface, and light is guided conveniently and difficultly leaked by connecting the reflecting surfaces of the arc surface 350, so that the light guide effect is enhanced.
As shown in fig. 6, while light is guided by the reflection surface of the reflection part 300, the reflection area 230 may be disposed on the front surface of the slat 210, and the reflection area 230 may reflect the light reflected by the reflection surface, change the direction of the light, and reflect the light toward the light incident side of the light guide plate 100, so that the light is sufficiently reflected into the light guide plate 100, thereby improving the light energy utilization rate.
In general, the display device has a display surface and a back surface, and the display surface, the back surface, the top surface, the bottom surface, the left side surface, and the right side surface are located on the side surfaces. The side-in type backlight structure in this embodiment is located inside the back plate, and the reflective portion 300 and the light bar 200 are disposed on one or more sides of the top, bottom, left, and right sides inside the back plate, and the light bar 200 is disposed in a direct-down type manner, so that the reflective portion 300 changes the propagation direction of light into a side-in type light-in type manner, thereby achieving a light guiding function.
