Description

导光板、背光模块及显示设备Light guide plate, backlight module and display device 技术领域Technical field
本发明涉及一种导光组件及其应用，特别是涉及一种导光板与导光板在背光模块及显示设备的应用。The invention relates to a light guiding component and an application thereof, in particular to an application of a light guiding plate and a light guiding plate in a backlight module and a display device.
背景技术Background technique
为符合背光模块薄型化的设计趋势，导光板的设计也趋向薄型化。然而，当导光板的厚度缩小时，发光二极管的高度并无法减小至与导光板相同的厚度。而且，当发光二极管的高度大于导光板的厚度时，导光板并无法有效利用发光二极管所产生的光线，而会导致导光板漏光。In order to meet the design trend of thinning the backlight module, the design of the light guide plate tends to be thinner. However, when the thickness of the light guide plate is reduced, the height of the light emitting diode cannot be reduced to the same thickness as the light guide plate. Moreover, when the height of the light emitting diode is greater than the thickness of the light guide plate, the light guide plate cannot effectively utilize the light generated by the light emitting diode, and the light guide plate may leak light.
为解决上述问题，一般背光模块中会使用特殊造型导光板来取代平板形导光板。特殊造型导光板主要包括渐缩部以及连接渐缩部的平板部。渐缩部靠近光源的一端厚度大于渐缩部与平板部连接的另一端厚度。藉此，光源所产生的光线可从厚度较大的渐缩部进入导光板而传播至平板部中。因此，导光板除了可通过渐缩部来接收并有效利用光源所产生的光线外，其平板部的厚度亦可对应缩减。In order to solve the above problem, a special shape light guide plate is generally used in the backlight module instead of the flat light guide plate. The special shape light guide plate mainly includes a tapered portion and a flat plate portion that connects the tapered portion. The thickness of one end of the tapered portion near the light source is greater than the thickness of the other end of the tapered portion connected to the flat plate portion. Thereby, the light generated by the light source can enter the light guide plate from the tapered portion having a large thickness and propagate into the flat plate portion. Therefore, in addition to the light guide plate receiving and utilizing the light generated by the light source, the thickness of the flat portion can be correspondingly reduced.
然而，特殊造型导光板虽然可解决上述问题，但当光线在特殊造型导光板中传播时，经常会从渐缩部与平板部连接的位置漏出，而严重影响导光板的光学外观。另一方面，特殊造型导光板的设计并不易与胶框或背光模块中的其他组件互相结合固定。However, although the special shape light guide plate can solve the above problem, when the light propagates in the special shape light guide plate, it often leaks from the position where the tapered portion and the flat plate portion are connected, and the optical appearance of the light guide plate is seriously affected. On the other hand, the design of the special shape light guide plate is not easy to be combined with other components in the plastic frame or the backlight module.
