撓曲液晶面板之雙層薄玻璃間的彎曲移位

Abstract

時代科技日新月異，液晶面板的製造技術變得更有創新變化，其中撓曲液晶面板是一個指標性產物，但製造過程中面臨許多挑戰，其中之一是製造撓曲面板的過程中，會造成上下薄玻璃間的彎曲移位，也是本文進一步欲了解的地方。這項因素會造成顯示器發光不均、顏色偏差等問題。本文即是要來探討撓曲液晶面板之雙層薄玻璃間彎曲移位的情形。微距鏡拍攝作為我們量測系統，再透過有限元素法軟體，考慮玻璃形狀及液晶特性，針對幾種不同的撓曲液晶面板，模擬移位距離的情形，最後研究並討論實際移位量與模擬移位量彼此間的差異。本文的目的即試著了解受影響的參數與建立一套物理模型，其結果更可作為未來研究的基礎並減少撓曲液晶面板缺陷發生的情形。

With the rapid development of technological science, the manufactured techniques of liquid crystal (LC) panel becomes more innovative and more creative. The curved liquid crystal display is one of the product during these innovations. However, it faces a lot of challenge in curved liquid crystal display. One of the major issue is the bending shift between the top and the bottom thin glass panels during manufacturing. This problem causes the light leakage and non-uniform color. In this thesis, we study the situation of the bending shift between two thin glass panels in curved liquid crystal display. A macro photography is set up for our measurement system. Through the finite element method software, we simulate the bending shift between two glass panels based on several models for curved display. The glass structure parameters and the optical properties of liquid crystal are considered in our simulation model. The difference error between the simulation result and the experiment result are investigated and discussed. The purpose in this study is trying to understand the affected parameters and to establish the physical model of the bending shift between two glass panels. Our results can be used as the basis for further study to eliminate the defect of the curved liquid crystal display.
