dc.description.abstract導光板是液晶螢幕的重要零件之一,因為導光板的設計和製造對於液晶面板的亮度及均勻性有著重大影響,尤其是非印刷式的楔型導光板入光面的微結構,是背光模組的輝度分佈關鍵因素,本文藉著探討應用單晶鑽石刀作精密微結構切削,來提升導光板品質。 本研究應用精密端面切削加工機,採用不同角度的單晶鑽石刀具,分別以不同的切削速度針對液晶顯示器背光模組用之導光板入光面進行V溝微細切削,再以輝度儀具量測輝度分佈,在切削面檢測方面,採用光學顯微鏡、雷射共軛焦電子顯微鏡作導光板V溝表面粗糙度與V溝斷面形狀量測,了解因不同的切削速度所得到表面粗糙度的狀況,對於光學輝度分佈的影響,進而求得最佳參數組合,以達到增加導光板光學品質的目的。 藉由本研究的實驗可以發現,對於導光板壓克力材質的切削模式,切削速度的提高,能夠產生較佳的切削表面,對此,在導光板的光學設計會有很好的參考依據,可提高整個背光模組的品質,縮短開發時間,節省開發成本。zh_TW
dc.description.abstractLight guide plate is one of the important parts of liquid crystal display . Because the design and manufacture of light guide plates has significant impact on the brightness and uniformity of liquid crystal panel . In particular, the luminance distribution of backlight module is critically affected to incident plate’s micro-structure of non-printed wedge light guide plate . In this paper the single crystal diamond tools are applied to precision cutting for micro-structure to improve the quality of light guide plate . In this study, the precision end-cutting machine would be applied . It will be used at different angles of the single crystal diamond tool and at variable cutting speed . To take a micro V groove structure process on the light guide plate’s incident plane of liquid crystal display’s backlight module , and then the distribution of luminance is measured by optical instrument . In the statement of the cutting surface inspection, using optical microscope and laser con-focal microscope to inspect the surface roughness and the section profile of light guide plate’s V groove , It can be found that the condition of surface roughness at variable cutting speed affects the distribution of optical luminance , and then acquires the best combination of parameters to achieve the objective which the quality of light guide plate is improved . It would be found what is the cutting mode of acrylic light guide plate through the cutting speed increased can get better cutting surface in the study’s experiments . Therefore , that has a good reference for optical design of light guide plates, improving the quality of the backlight module , shortening the time of development and saving the costs of research .en_US
