液晶电光效应实验报告(6)

2、由表2和所作的开关时间响应特性曲线可以得到液晶上升时间和下降时间。

3、由表3和表4的对比可以观察到液晶的视角特性可以得出：水平方向上全测量范围内都有良好的视觉效果既可以获得不错的图像，而在垂直方向上仅在-8.0度—6.0度之间有较好的视觉效果，其余角度都很难获得清晰的图像。

Abstract: Liquid crystal is a kind of polymer material, because of its special physical and chemical

properties, special optical properties, as well as be sensitive to electromagnetic, now has been widely applied in thin type display technology

Key words: liquid crystal, electro-optical properties, response time, viewing angle characteristics

Liquid crystal is between liquid crystals and between states of matter. The liquid crystal not only has the fluidity of the liquid, but also its molecular is orderly arranged according to a certain rule, making it the crystal anisotropy. When light passes through the liquid crystal, it will produce a polarization rotation, double refraction and so on. The liquid crystal molecules containing polar groups of polar molecules, under the action of the electric field, dipole will be directed by electric field, causing the molecules to the original arrangement changes, and optical properties of liquid crystals have been changed. The external electric field induced liquid crystal optical properties change known as the electro-optic effect of liquid crystal. The measurement of liquid crystal optical switch optical characteristic curve, get the liquid crystal threshold voltage and the turn-off voltage; The measurement of periodic changes when the driving voltage of liquid crystal optical switch time response curve, get the liquid crystal the rise time and the fall time; The measurement by liquid crystal optical switch matrix composed of the liquid crystal display characteristics in different perspective and from the perspective of in contrast, understand the liquid crystal optical switch working conditions. Understand the liquid crystal optical switch consists of image matrix method, study and master the matrix formed by a liquid crystal display forms of text and graphics display mode, thus the general understanding of the principle of liquid crystal display device. 学号 1143041073 电话 18215600560 email 541075655@ 学期 2012年 春
