Line is more uniform.
Preferably, it is adjacent as shown in figure 4, when light guide structure 013 includes multiple groove 0131 in matrix form arrangement
Two spacing W of groove 0131 are 50mm~90mm.
If the spacing W between two neighboring groove 0131 is less than 50mm, will necessarily increase and be corresponded with groove 0131
Light source 02 quantity, so, the processing cost of backlight module will be increased due to the increase of the quantity of light source 02.If phase
Spacing W between adjacent two grooves 0131 is more than 90mm, then can cause corresponding exiting surface 011 on two neighboring groove 0131
Because beam projecting amount is less at position between emergent ray overlay area, dark space is produced, so that light guide plate 01 is whole
The light of outgoing on individual exiting surface 011 produces the uneven phenomenon of light and shade.
Further, as shown in FIG. 4 and 5 (Fig. 5 is the upward view of Fig. 4), groove 0131 is corresponded with light source 02

Have between overlay area on 01 exiting surface 011 light irradiation less than dark space, reduce on the exiting surface 011 of light guide plate 01
The uneven phenomenon of the light and shade of the light for sending.
Additionally, the setting of groove 0131 can also be the situation of (Fig. 6 is the upward view of Fig. 4) as shown in Figure 6, multiple grooves
0131 is the strip slot being parallel to each other, and the bearing of trend along groove 0131 in each groove 0131 is provided with multiple point-like
Light source 02, diverse location of the multiple light sources 02 in same groove 0131 enters along the side with angle of inclination of groove 0131
The light penetrated, equally enables to the incident angle of light source 02 to increase, and reduces dark space, and reducing sent out on the exiting surface 011 of light guide plate 01
The uneven phenomenon of the light and shade of the light for going out.Compared with the groove 0131 in Fig. 4, the quantity of groove 0131 in Fig. 5 is few, area is big,
It is more readily processed, it is possible to increase the processing yields of light guide plate 01.
Further, as shown in figure 3, light guide structure 013 includes multiple sites 0132 in matrix form arrangement, site
0132 is arranged on part of the incidence surface 012 in addition to the position of corresponding light source 02.
So, the light that light source 02 sends is incident to after the inside of light guide plate 01, by the light of total reflection to remote
From the direction directive incidence surface 012 of light source 02, due to the site of the part in incidence surface 012 in addition to the position of corresponding light source 02
0132 scattering process so that light is sent by the scattering of exiting surface 011, improves the uniformity of emergent ray.
Preferably, the longitudinal cross-section of groove 0131 is U-shaped, V-arrangement (such as Fig. 3), rectangle (such as Fig. 2) or trapezoidal (such as Fig. 9)
Any one, the longitudinal cross-section figure of groove 0131 is vertical with exiting surface 011 or incidence surface 012.
It should be noted that longitudinal cross-section described herein is U-shaped, V-arrangement, rectangle or trapezoidal groove 0131, only lift
Example, groove 0131 can also be that other longitudinal cross-section figures include with the incidence surface 012 of light guide plate 01 there is angle to be no more than 90 °
Acute angle side wall figure, the light that light source 02 sends can be made further to increase large angle incidence by the side of groove 0131
.Wherein, preferred scheme is that the longitudinal cross-section figure of groove 0131 is zhou duicheng tuxing, when the longitudinal section of light guide plate 01 is
During wedge structure, the symmetry axis of the longitudinal cross-section figure of groove 0131 can be vertical with exiting surface 011, or with enter light
Face 012 is vertical.No matter the longitudinal cross-section figure of groove 0131 symmetry axis it is vertical with exiting surface 011, or with incidence surface 012 hang down
Directly, when groove 0131 has multiple on the incidence surface 012 of light guide plate 01 in cells arranged in matrix, the shape of multiple grooves 0131

Together, it is more uniform with the light of outgoing on the whole exiting surface 011 for causing light guide plate 01.
Preferably, as shown in figure 3, when the longitudinal cross-section of groove 0131 is V-arrangement, the apex angle ss of V-arrangement is 80 °~130 °.
If the apex angle ss of V-arrangement is less than 80 °, closer to the distance between two light incident sides of groove 0131, light source 02 is by groove
The light efficiency of the light of 0131 incidence is relatively low；If the apex angle ss of V-arrangement is more than 130 °.Then two light incident sides pair of groove 0131
Light source 02 is poor by the ability of the further increase angle of the light of the incidence of groove 0131, the exiting surface above the correspondence of light source 02
Emergent ray is more concentrated at 011 position, forms bright band, causes the light and shade on the exiting surface 011 of whole light guide plate 01 uneven existing

The light of outgoing at the position of exiting surface 011, it is to avoid emergent ray is more concentrically formed bright band herein, while light can be uniform
To the outgoing of exiting surface 011 away from light source 02.When the groove 0131 that longitudinal cross-section is V-arrangement is on the incidence surface 012 of light guide plate 01
When having multiple in cells arranged in matrix, multiple light sources 02 corresponding with groove 0131 are in the same direction by the one of groove 0131
Individual side is incident, and the light this makes it possible to outgoing on the exiting surface 011 for reducing whole light guide plate 01 is above the correspondence of light source 02
The degree of bright band is formed, and causes that the light of the outgoing of whole exiting surface 011 is more uniform.
Preferably, when groove 0131 longitudinal cross-section be rectangle or trapezoidal (as shown in Figure 10) when, the rectangle or it is trapezoidal
Away from having multiple continuous concaveconvex structures on the surface of the side of incidence surface 012.
For example, as shown in Figure 10, when light source 02 is trapezoidal groove 0131 away from the side of incidence surface 012 by longitudinal cross-section
During the incidence light guide plate 01 of surface, irradiation straight up or between vertical direction the less light of angle expose to it is trapezoidal away from entering
The surface of the side of smooth surface 012, acts on through the irregular reference of the continuous concaveconvex structure of multiple on surface, and reflection light is scattered by each
Individual angle is incident to exiting surface 011, and by the outgoing of exiting surface 011, at the exiting surface 011 above the correspondence of light source 02
Emergent ray more concentrate, and form bright band, cause the bright and dark light of the outgoing of exiting surface 011 uneven.
It should be noted that the continuous concaveconvex structure of described multiple is not limited to the shape shown in Figure 10, can also be
Continuous pit, raised or other structures, as long as there is the structure of the change in direction i.e. in the light that can make to expose to thereon
Can, the concrete shape to concaveconvex structure is not limited herein.
Additionally, when the longitudinal cross-section of groove 0131 is rectangle, the knot on the surface away from the side of incidence surface 012 of rectangle
Structure, and light path trend is identical when being trapezoidal with the longitudinal cross-section of groove 0131, and here is omitted.
Preferably, as shown in fig. 7, the incidence surface 012 of light guide plate 01 is cambered surface, cambered surface supports or opposes and separates out the direction of smooth surface 011
Bending.
So, when the incidence surface 012 of light guide plate 01 separates out the cambered surface of direction bending of smooth surface 011 to support or oppose, by
Light source 02 injects the light in light guide plate 01, through the total reflection of exiting surface 011 after, to the direction directive incidence surface away from light source 02
012, the site 0132 on arc incidence surface 012 can be sent uniform light by the scattering of exiting surface 011, further be improved out
