Embodiment 1
[0032] The light guiding device provided by the embodiment of the present invention, such as Figure 4 and Figure 5 As shown, on the basis of the classic structure of the traditional side-type backlight (light sources are provided on the opposite sides of the light guide plate), light guide strips are added to the two sides of the light guide plate adjacent to the light incident surface; the light guide The side of the bar close to the light source is called the end face (one of the end faces is Figure 4 The end face 410 shown in ), the end face is the light incident surface of the light guide strip, the side 411 connected to the light guide plate is the light exit surface of the light guide strip, and the side 412 opposite to the light exit surface 411 is the light reflection of the light guide strip surface; the side of the light guide plate that is in contact with the light emitting surface 411 of the light guide strip becomes a new light incident surface of the light gu...
Embodiment 2
[0047] For the side-type backlight that only sets the light source on one side of the pair of sides of the light guide plate (the side of the light guide plate 413 and the side opposite to it), and sets the reflective film on the other side opposite to the light source, add The technical solution of the light guide strip is basically consistent with the above-mentioned embodiments. The end surface of the light guide strip close to the light source is the light incident surface of the light guide strip, and the end surface opposite to the light incident surface, the reflective surface of the light guide strip, and the upper and lower surfaces of the light guide strip are all provided with reflective films; in this implementation The biggest difference between the light guide strip in the example and the light guide strip in Embodiment 1 is that the dot distribution density on the reflective surface of the light guide strip is different. Although the dots on the light guide stri...
Embodiment 3
[0050] Such as Figure 13 As shown, for a side-type backlight with a light source on a pair of sides of the light guide plate, the light guide strip can also be added in the following way, that is, two light guide strips are respectively arranged on the outside of the other pair of sides of the light guide plate , the two light guide strips are located at both ends of the side of the light guide plate, and the end faces of the two light guide strips close to the light source are aligned with the main light incident surface of the light guide plate; that is, on the light guide plate The outer sides of the four corners are respectively provided with light guide strips correspondingly.
[0051] The end surface of the light guide strip close to the light source is the light incident surface of the light guide strip, and the end surface opposite to the light incident surface, the reflective surface of the light guide strip, and the upper and lower surfaces of the light guide strip ...
