dc.description.abstract本論文乃是根據超低耗能綠色顯示系統(Ultra-Low Power Eco LCD System)的概念,所提出一高效率低耗能的智慧型平面背光光源系統。其核心概念為利用發光二極體(Light Emitting Diode, LED)陣列與菲涅爾透鏡(Fresnel Lens),組成一以菲涅爾透鏡之光軸為對稱軸且可調整出射光場角度之發光源系統。在本論文中,首先提出該光源系統實際之設置,藉由切換陣列中位於光軸或偏離光軸之LED,提供正向模態(normal viewing mode)以及斜向模態(oblique viewing mode)等不同角度分佈的光場,並定義各模態之規範。除此之外,針對其角度分佈以及光場均勻性做進一步優化。利用此可調變光場角度的背光模組所組成之顯示器,可根據實際使用情況調變光源,在兼具經濟效益及節能考量之下,期望能達到一能依觀賞環境與觀賞者位置調整之智慧型多角度節能背光模組。zh_TW
dc.description.abstractAim at the concept of the Ultra-Low Power Eco LCD System, a smart planar backlighting system with high optical efficiency was proposed. The novel backlight system is composed of a light emitting diode (LED) array and cylindrical Fresnel lens. This lens can exhibit flexibility on angular distribution of the emitting optical field. In this thesis, the opto-mechanism setup and the niches of a backlight system would be introduced, discussed how to provide the normal and oblique viewing modes via controlling the LEDs individually. Furthermore, issues of the backlight system on angular distribution and uniformity would be optimized. In addition, the display subject to the above backlight module could reduce the power consumption and improve the economic efficiency by adjusting the LED power ratio. According to the observer’s direction, a viewing switchable backlight can be modulated with different angular distribution.en_US
