The invention relates to a light guide plate and its producing method, the light conducting plate includes a plate body; the plate body is provided with a smooth surface, with the light out face to a reflective surface, and the contact with the light emitting surface and the reflection surface of the at least one light incoming surface; and at least one positioning part; at least one side of the positioning part is connected to the board body; light guide plate making method is realized by the following steps: providing at least a light guide plate, the light guide plate comprises a plate body, and connected to the plate body at least one positioning part, wherein, the plate has a smooth surface, with the light out face to a reflective surface, and the contact light emitting surface and the reflection surface of the at least one light incoming surface; provide a tool coupled to the positioning part and the fixed plate; and providing at least a cutting tool for processing the plate into the surface, and in the light The utility model has the beneficial effects that the light can be uniformly injected into the injection light surface to provide a uniform surface light source.
【技术实现步骤摘要】
本专利技术涉及一种导光板，尤其涉及该导光板结构及其制作方法。技术背景薄型化液晶显示装置通常是利用发光二极管及导光板构成的背光模块来产生面 光源，以照明液晶显示面板。一般而言，作为点光源的发光二极管会设置在导光板的侧面 (入光面)以提供光线入射到导光板内。然而，为了顺利地使光线从导光板的侧面入射到导 光板内，必须将发光二极管设置在相对于导光板的侧面为特定的角度范围内，而造成组装 不易。另外，随着导光板的厚度变薄的趋势，导光板的侧面的面积变小，使得来自发光二极 管的光线更不易从导光板的侧面进入导光板内。图1为现有技术的导光板的示意图。请参照图1，导光板100具有出光面112、反 光面114及入光面116。通常是利用冲压模具来切割出一定尺寸的导光板100。然而，当对 于厚度较薄的导光板100进行冲压时，往往会在导光板100的入光面116的一侧形成毛边 120。由图1中的放大图来看，毛边120突出于导光板100的入光面116，这会造成毛边120 附近区域的光学效果不同于其它区域的光学效果，导致光线无法均勻地进入导光板100。另外，有研究者在对于厚度较薄的导光板100...
