It is beneficial to further improve the light-emitting brightness of the light guide plate.
2. 第一连接面、第一受光面、第二受光面以及第三受光面均呈平面设置，一方面有利于有效对朝向出光侧的方向射出的入射光线起到指向性引导的作用，另一方面有利于扩大光线反射后落在导光板的出光面的范围，因此有利于实现入射光能够更加均匀地分布于导光板的出光面上。2. The first connecting surface, the first light-receiving surface, the second light-receiving surface and the third light-receiving surface are all arranged in a plane. On the one hand, it is beneficial to expand the range of the reflected light falling on the light exit surface of the light guide plate, so it is beneficial to realize that the incident light can be more uniformly distributed on the light exit surface of the light guide plate.
3. 第一受光子面与第二受光子面连接并形成夹角的角度范围为60°-170°，第三受光子面与第四受光子面连接并形成夹角的角度范围为60°-170°，使得第一受光子面、第二受光子面、第三受光子面以及第四受光子面组合形成具有收拢光线的结构，有利于进一步将入射的光线收拢，以降低入射的光线直接从导光板的出光侧穿出的可能性，使得更多的光线能够反射至导光板的出光面上，有利于降低光损、提高光能利用率，同时有利于提高导光板的出光亮度。3. The angle range between the first photoreceiving surface and the second photoreceiving surface is 60°-170°, and the angle where the third photoreceiving surface is connected to the fourth photoreceptor surface is 60° -170°, so that the first photon-receiving surface, the second photon-receiving surface, the third photon-receiving surface and the fourth photon-receiving surface are combined to form a structure with a light-receiving structure, which is conducive to further condensing the incident light and reducing the incident light. The possibility of directly exiting from the light-emitting side of the light guide plate allows more light to be reflected on the light-emitting surface of the light guide plate, which is conducive to reducing light loss, improving the utilization rate of light energy, and improving the light output brightness of the light guide plate.

具体实施方式Detailed ways
以下结合附图1-26对本申请作进一步详细说明。The present application will be further described in detail below in conjunction with accompanying drawings 1-26.
图1所示的是相关技术中带有网点结构的导光板结构，导光板包括导光板本体1。使用导光板时，一般在导光板本体1的一侧设置光源11，导光板本体1靠近光源11的一侧为入光侧，导光板本体1靠近光源11的一侧为出光侧，导光板本体1的出光面101位于入光侧和出光侧之间，且网点面102位于出光面101的相对面，导光板本体1的网点面102上设置有若干网点结构2，该网点结构2基本呈半球状，因此会导致光线主要集中在导光板本体1的出光面101靠近入光侧的一侧，而导光板本体1的出光面101靠近出光侧的一侧亮度较小，由此导致光线难以均匀分布在导光板本体1的出光面101上，同时由于呈半球状的网点结构2的受光面较小，导致光源11大部分的光线从导光板的出光侧射出，由此导致导光板的光损较大，从而导致导光板的出光亮度较低。FIG. 1 shows a structure of a light guide plate with a dot structure in the related art. The light guide plate includes a light
基于上述相关技术的情况，为了减少导光板的光损，使得光线能够均匀分布于导光板的出光面101，并且提高导光板的出光亮度，本申请公开一种导光板的网点结构。参见图2，导光板本体1由PMMA材料制得，也可以由PC材料或PS材料制得。导光板本体1的网点面102上设置有若干网点结构2，若干网点结构2随机排布于导光板的网点面102上，该网点结构2为异形结构。Based on the above-mentioned related art, in order to reduce the light loss of the light guide plate, make the light evenly distributed on the
实施例1：Example 1:
参见图2和图3，导光板的网点结构2包括第一受光面3、第二受光面4以及若干第一连接面5。第一受光面3、第二受光面4以及第一连接面5均为平面，且第一受光面3、第二受光面4均为长方形。第一受光面3的一侧边与第二受光面4的一侧边相互连接并形成夹角，第一受光面3背离第二受光面4的侧边与导光板的网点面102连接并形成夹角，第二受光面4远离第一受光面3的侧边与导光板本体1的网点面102连接并形成夹角。第一受光面3与第二受光面4的另外两侧边分别通过第一连接面5与网点面102连接。在一种实施方式中，第一受光面3和第二受光面4的面积相等，在其他实施方式，第二受光面4的面积也可设置为大于第一受光面3的面积，以使得第二受光面4能接收更多的入射光线并将更多的入射光线反射至导光板本体1的出光面101上，由此提高导光板的出光亮度。Referring to FIGS. 2 and 3 , the
参见图4，第一受光面3的一侧自网点面102沿朝向第二受光面4的方向呈倾斜设置。为了进一步提高导光板的出光亮度，第一受光面3与网点面102的夹角为锐角。为方便理解，将第一受光面3与网点面102的夹角设置为a1，夹角a1的范围可进一步优选为10°-60°，这样设置有利于提高反射光线的扩散范围。将第一受光面3与第二受光面4的夹角设置为b1，夹角b1的范围为60°-170°。将第二受光面4与网点面102的夹角设置为a2，夹角a2范围可进一步优选为10°-60°。在本实施例中，夹角a1优选为30°，夹角b1优选为140°，这样设置一方面使得第二受光面4能够对直接射向出光侧处的光线起到指向性引导的作用，有利于使得更多的光线能反射至出光面101，因此有利于提高亮度，另一方面，第二受光面4使得入射光线能够反射至出光面101靠近出光侧的位置，有利于将反射的光线能均匀分布在出光面101上。Referring to FIG. 4 , one side of the first light-receiving
在一种实施方式中，如图4所示，为方便理解，在网点面102与第一受光面3的连接处设置有分割线L1，分割线L1将夹角a1划分为两个子角，当两个子角的角度大小相等时，夹角a1对称式夹角；当两个子角的角度大小不相等时，夹角a1非对称式夹角，同理可得，夹角a2可以为对称式夹角或非对称式夹角。In one embodiment, as shown in FIG. 4 , for the convenience of understanding, a dividing line L1 is set at the connection between the
在一实施方式中，如图4所示，为方便理解，在第二受光面4与第一受光面3的连接处设置有分割线L2，分割线L2将夹角b1划分为两个子角，当两个子角的角度大小相等时，以使得夹角b1对称式夹角；当两个子角的角度大小不相等时，夹角b1非对称式夹角。In one embodiment, as shown in FIG. 4 , for the convenience of understanding, a dividing line L2 is provided at the connection between the second light-receiving
在一种实施方式中，导光板本体1的出光面101上开设有多个切槽1011，切槽1011为V形切槽1011，经过网点结构2反射后的光线反射至出光面101的V形切槽1011处，V形切槽1011在此改变反射光的传导方向，使得导光板出光更均匀。In one embodiment, the light-emitting
在另一种实施方式中，导光板的出光面101上的切槽1011为半弧形切槽1011，经过网点结构2反射后的光线反射至出光面101的半弧形切槽1011的槽壁处，使得反射光沿着半弧形槽的弧度方向出射，使得导光板出光更柔和。In another embodiment, the

图15显示的是本实施例中网点结构2的光路图，第一受光面3与第二受光面4连接形成朝向出光面101的方向凸出的曲面，由于第一受光面3与第二受光面4配合朝向出光面101的方向凸出，因此达到将更多的入射光均匀地反射至导光板的出光面101上，光线有效利用在有效视区以内，还能够使得入射光经过该曲面的反射后能够从不同的方向射至导光板的出光面101上，由此能够使得导光板的出光面101上的光线更柔和。FIG. 15 shows the optical path diagram of the
在另一种实施方式中，参见图16和图17，基于第一连接面5设置为曲面的结构下，将第一受光面3以及第二受光面4均设置为平面。参见图18，第一受光面3与第二受光面4连接处朝向出光面101的方向凸出并形成夹角c1，在本实施方式中，夹角c1的角度范围为60°-170°，夹角c1可选为60°、70°、80°、90°、100°、110°、120°、130°、135°、140°、145°、150°、155°、160°或170°等，夹角c1大小的改变能够改变光线反射至导光板出光面101的位置，而将夹角c1设置在上述范围内，有利于使得更多的光线能更均匀地反射至导光板出光面101。In another embodiment, referring to FIGS. 16 and 17 , based on the structure in which the first connecting
第一受光面3与第二受光面4连接处朝向出光面101的方向凸出，能够实现接收更多的入射光，同时能够将更多的入射光扩散至导光板的出光面101上，以提高导光板的出光亮度，同时也有利于使得光线能更均匀地分布在导光板的出光面101。The connection between the first light-receiving
