According to different Cell gap, the diameter of spacer varies from 2 to 6 um. There are various types of spacer, and it is differentiated into ball spacer and photo spacer.

Staggered structure TFT

TFT的构造依晶体管构成要素的配置方法大致区分为stagger型与coplanar型。前者指的是在gate电极╱gate绝缘膜与source╱drain电极之间配置半导体。后者指的是在gate电极╱gate绝缘膜与半导体之间配置source╱drain电极。另外还衍生出gate电极是在TFT上部（top gate）或下部（bottom gate）的类型。顺stagger构造是gate电极配置于上部之stagger构造，使用于部份的a-Si TFT LlCD上。 英：

TFT structure is divided into stagger type and coplanar type according to the ways the transistors are constructed. Stagger type means the semiconductor is fixed in between gate electrode / gate insulating film and source / drain electrode. Coplanar type means the source / drain electrode is fixed in between gate electrode / gate insulating film and transistor. There is also another TFT types which fits the gate electrode on either top gate or bottom gate of the TFT. When the gate electrode is fitted to the stagger on top gate, it is known as Staggered structure TFT, and it is applied partially to a-Si TFT LCD.

Step coverage

STN

Super Twisted Nematic

具有扭转约180度~270度构造的nematic液晶或采用namatic液晶的显示类型。以一定角度射入到液晶分子轴上的直线偏光由于双折射性的缘故而变调成椭圆偏光。利用电场的有无将液晶分子控制在STN构造与垂直配向之间，即可用双折射性的变调加以驱动。黄色或蓝色是较普遍的，采用特殊的位相膜或补偿液晶板作白色显示，也可以应用于彩色显示上。与TN相比其视角较广，但缺点是应答速度慢。 英：

STN has nematic LC which can twist from 180 degrees to 270 degrees or uses namatic LC displa

y type. With a fixed angle, the straight polarizer shoots on to the axis of the LC molecule and because of the birefringence property, the straight polarizer becomes ellipse polarizer. By utilizing the existence of electrical field to control the LC molecule to stay in between the STN structure and vertical orientation, STN can be drove from the property of birefringence. Generally, they are in either yellow or blue color, and it can display white color when special phase film or compensated LC board. This also applies to color display. Comparing with TN, it has a wider viewing angle, but the disadvantage is slow in response speed.
