Description
本發明係關於一種適用於提供光源背光之複合式導光板及其製造方法，尤指一種適用於液晶面板背光用之複合式導光板、及其背光模組。The invention relates to a composite light guide plate suitable for providing backlight of a light source and a manufacturing method thereof, in particular to a composite light guide plate suitable for liquid crystal panel backlight and a backlight module thereof.
隨著光源科技的進步，許多相關的光源產品逐漸的由研發階段進入市場，發光面板即為其中之一例，係為一種應用面廣的光源模組。With the advancement of light source technology, many related light source products have gradually entered the market from the research and development stage, and the light-emitting panel is one of them, which is a light source module with a wide application range.
一般而言，發光面板包括有：導光板、稜鏡片、反射板、及擴散板。其中，導光板是發光零件模組中的光導引媒介。若應用於側光型的背光模組，它可導引光線方向，提高面板光亮度及控制亮度均勻。在外型上又區分為：楔型板與平板，一般筆記型電腦因空間關係均採用楔型板，而發光二極體電視則以平板為主。稜鏡片主要是用於提高面板的亮度，以此來集中光源，反射板則將未被散射的光線反射至導光板中，擴散板主要是在使光線均一化。Generally, the light emitting panel includes: a light guide plate, a breeze plate, a reflective plate, and a diffusion plate. Wherein, the light guide plate is a light guiding medium in the light emitting part module. If applied to a side-light type backlight module, it can guide the light direction, improve the brightness of the panel and control the brightness uniformity. In terms of appearance, it is divided into: wedge plate and flat plate. Generally, the notebook computer adopts a wedge plate due to the spatial relationship, and the light-emitting diode TV is mainly a flat plate. The cymbal is mainly used to increase the brightness of the panel to concentrate the light source, and the reflector reflects the unscattered light into the light guide plate. The diffuser is mainly to homogenize the light.
發光面板的工作原理乃利用全反射將光源傳至導光板，再利用導光板的底面的反射板擴散光源，反射光會往各個角度擴散，而後，將光源導引至導光板正面，折射率越大，其導光能力越好。The working principle of the light-emitting panel is to transmit the light source to the light guide plate by using total reflection, and then diffuse the light source by using the reflector on the bottom surface of the light guide plate, the reflected light will diffuse to various angles, and then the light source is guided to the front surface of the light guide plate, and the refractive index is higher. Large, its better light guiding ability.
由於一般的發光面板均需裝設導光板、稜鏡片、反射板、及擴散板等元件，因此其製程往往需要採用多層並排的方式，才能具備有發光的功效。若能將稜鏡片、反射板、及擴散板等元件組設於導光板上，將可大幅減少所需的層數，也能提高發光效率。Since the general light-emitting panel needs to be equipped with components such as a light guide plate, a breeze plate, a reflector plate, and a diffuser plate, the process of the light-emitting panel often needs to be multi-layered side by side in order to have the effect of emitting light. If a component such as a ruthenium, a reflector, and a diffusion plate can be disposed on the light guide plate, the number of layers required can be greatly reduced, and the luminous efficiency can be improved.
