近年來由於消費性電子產業的蓬勃發展,對於液晶顯示器的需求也日漸增加,使得對於液晶顯示器畫面的要求,動態影像的呈現,其標準也逐漸的提高。然而,液晶的反應時間在應用的溫度中對於畫面動態影像的流暢度有絕對的影響,故本文的研究著重於探討液晶溫度依賴性與反應時間。
首先分別討論液晶的預傾角和溫度效應對液晶反應時間的影響,並利用液晶各種物理特性與理論推導,以證明此兩種效應對於液晶反應時間有絕對影響力。最後藉由比較理論推導與實驗結果,驗證模型的正確性;根據此結論可有效地瞭解液晶反應時間,使液晶顯示器的動態影像切換更為流暢,藉此提高其產品價值。
There has been a rapid development of consumptive electronic industry recently, and LCD becomes more and more important. Now, people pay much more attention to the quality of LCD screen and the presence of the dynamic imaging. It is true that the response time of liquid crystal at applied temperature has a great influence on the fluency of dynamic imaging. Therefore, the thesis will focus on researching the temperature-dependent response time of liquid crystals.
First of all, the thesis introduces how pretilt angle and temperature effects influence on the response time of liquid crystal. Then, proving from the theoretical derivation, these two effects indeed have much influence on the response time of liquid crystal. At last, we verify the models by comparing with theoretical derivation and the experimental results. In addition, according to the results, the response time of liquid crystal can be effective in understanding and the dynamic image switching can become much smoother. In this way, the product value will increase.
