近年來軟性顯示器(Flexible Display)相關產品越來越受注目如:電子紙(E-Paper),然而當欲想呈現出顯示器的畫面時必須要有光,因此本研究以背光模組(Backlight system)的發光原理,應用於電子紙上,將影像呈現出來。 現行導光板(Light guide plate)已經很廣泛的應用於光電顯示的相關產品,其材質為不具可撓性的PMMA,因此本研究提出一具有高可撓性、高透光性的熱塑性聚胺基甲酸酯(Thermoplastic Polyurethane; TPU)高分子材料,來做本次研究軟性導光板的材料,並以滾軋(Rolling)連續生產的方式來製作導光板,此方法可加速生產速度及大量生產,可以有效較低生產成本。 以滾壓製作所製作的導光板,轉移率達可87%,利用BM-7光學量測系統對軟性導光板量測,平放時均勻度可達80%以上;當彎曲15度時光衰退率只有20%。因此本研究成功製作出用於軟性顯示器之導光板。
In recent years, it makes emphasis on flexible displays, such as: electronic paper (E-Paper), but when you want to show the display screen must be light, so this study Backlight unit of the light principle, applied to electronic paper, the image presented. LGP (Light guide plate) has been very widely used in optical display related products, LGP made of non-Flexible in PMMA. Therefore, this study has put forward a highly flexible, high light transmittance of the thermoplastic polyurethane (Thermoplastic Polyurethane; TPU) polymer material to do the study of soft light guide material. And to rolling (Rolling) continuous production methods to produce LGP, this method can accelerate the speed of production and mass production, can effectively lower the cost of production. Produced by the LGP rolling production, the transfer rate can be 87%, the use of BM-7 optical measurement system for measuring the soft LGP, when the flat uniformity of up to 80%. LGP bending 15-degree the light decline rate was only 20%. Therefore, this study successfully used to produce flexible displays of the light guide.
