弱锚定条件下超扭曲向列相液晶显示的特征电压

互联网摘选

All Twisted nematic ( TN) and supertwisted nematic ( STN) LCD, including both active and passive matrix, suffer from poor performance at wide viewing angles due to the electro optical properties of the liquid crystal materials.

扭曲向列型（TN）和超扭曲向列型（STN）LCD，包括有源和无源矩阵，都有一个共同的缺点，即视角狭窄；这是液晶材料的电光特性所造成的。
