量子點背光模組的色域優化

隨著液晶平面顯示器產業的成熟，應用於各種產品的發展已經非常多元化，現今的顯示器產品已經與人們的生活有著密不可分的關係，近兩年來，顯示器產品除了追求高解析度的畫質呈現能力之外，對於色域表現的水準以及護眼的需求也開始被市場與消費者所重視。檢視液晶平面顯示器(Liquid Crystal Display, LCD)的技術架構，背光源的設計一直是LCD的關鍵設計，目前具有成本優勢的設計大多採用藍光的發光二極體(Light-emitting Diode, LED)晶片，搭配螢光粉材料來獲得接近白光的背光源效果，實際上這種作法雖具備低成本效益，但也因為缺乏真實紅光/綠光混合光源讓LCD的色域顯示能力因此受限。然而更加需要關注的問題是背光源上的藍光，LCD所採用的背光源通常是波長445nm的高能量短波藍光，它的穿透力較強，人眼一旦接受了過多的藍光照射，就會導致視網膜黃斑部發生病變，並造成視力的損傷。本文針對目前LCD普遍存在色域表現不佳的缺點，如何在背光設計中使用量子點膜片來提升色域表現已達到廣色域平面顯示器的要求，並藉由抗藍光的技術來降低藍光對人眼的傷害。

With the LCD flat panel display industry is mature, used in a variety of product development has been very diversified, today's display products and people's lives have a close relationship between the past two years, in addition to the pursuit of high-resolution display quality picture Capacity, the level of performance for the color gamut and eye protection needs began to be market and consumer attention. LCD technology, the design of the backlight has been the key to the design of the LCD, the current cost advantage of the design of most of the use of blue light-emitting diodes (Light-emitting Diode, LED) chip, With phosphor material to get close to the white backlight effect, in fact, although this approach has a cost-effective, but also because the lack of real red / green hybrid light source so that LCD's color gamut display capacity is limited. However, more attention needs to be concerned about the blue light on the backlight, LCD backlight is usually used in high-energy wavelength of 445nm short-wave blue light, its penetration is strong, once the human eye to accept too much blue light, it will lead to Macular degeneration occurs, and cause vision damage. In this paper, the LCD for the current widespread poor performance of the shortcomings of the color gamut, how to design the use of quantum dots to improve the color gamut has reached the performance requirements, and by anti-Blue-ray technology to reduce the blue light on the Eye damage.
