摘要: | 液晶顯示器在我們生活中非常的常見,像是手機、電腦、電視、平板等的螢幕都是液晶顯示器,而近年來由於藍相液晶擁有許多傳統液晶所沒有的優點像是超高速響應、更簡單的製程等造成了藍相液晶的崛起。
目前的主流面板- TN (Twisted Nematic)液晶、VA (Vertical Alignment)模式液晶以及IPS (In-plane Switching)模式液晶都需要配向膜,並且需要多個製程來實施機械性配向處理。而藍相液晶結構則很簡單,不需要配向膜,因此無需機械處理,對液晶及其界面的損傷小,面板表面亮度均勻;而且只需要偏光板的光學膜片,相較之下體積與重量又可進一步減少。 然而藍相液晶面板顯示器仍有高驅動電壓、顯示對比較低等缺點。因此,工程師們目前的重要課題便是透過面板結構改良來達到高亮度與低操作電壓。而本篇論文就會提出新的結構設計來達到高亮度與低操作電壓的藍相液晶顯示器。 在本篇論文中,首先會有2D平面型的IPS、FFS、FIS與突起式FIS的研究比較,再來則是3D的研究比較,最後會把2D與3D一起總結出3D的優點及缺點以及2D FIS與3D FIS的比較。 LCD monitors are very common in our lives, such as mobile phones, computers, televisions, flat screens, etc. are LCD displays. In recent years, due to the advantages such as ultra-high-speed response and more simple process of blue phase LCD than traditional LCD, blue phase LCD rises. The current mainstream panel - TN (Twisted-Nematic) liquid crystal, VA (Vertical Alignment) mode liquid crystal and IPS (In-Plane-Switching) mode liquid crystal need alignment film, and requires many processes to implement mechanical alignment processing. The blue phase liquid crystal doesn’t need mechanical treatment, due to its simple structure and needless of alignment film. So it has less interface damage and uniform panel surface brightness. Moreover, it only need polarizing plate optical film so the volume and weight can be further reduced. However, the blue-phase LCD display still has shortcomings such as high drive voltage and low display contrast, etc. Therefore, the current important topic for engineers is to design the panel structure to achieve high transmittance and low operating voltage. Consequently, this paper will propose a new structure to achieve high transmittance and low operating voltage of the blue phase LCD display. In this paper, first there are comparisons of 2D flat type IPS, FFS, FIS and FIS with protrusion structure. Second, it is 3D type research comparison. Finally, it sums up 2D type and 3D type to compare the advantages and disadvantages. |
