White Background Liquid Crystal Inside The TN/HTN LCD Screen

Most of the liquid crystal display components used for pen segment digital display are TN or HTN type LCD LCD screens.

The basic structural principle of the TN/HTN liquid crystal exposure component is: The glass coated with ITO transparent conductive layer is photolithographed with a certain transparent electric plate pattern, and the front and back two glass substrates with transparent conductive electrode pattern are sandwiched with a layer of liquid crystal material with positive dielectric anisotropy of nematic LCD LCD screen, and the surrounding area is tightly sealed to form a flat liquid crystal box with a thickness of only a few microns.

The exposed component of an LCD LCD screen is commonly a liquid crystal that is not displayed on an LCD. Common wrist watches, digital instruments, electronic clocks and most calculators use liquid crystal display components are TN/HTN type LCD components. Because of this, this component should be a liquid crystal display device clearly known to many people.

Twisted nematic phase (TN) is exposed because a directional film is coated in the glass of the LCD LCD screen, and directional treatment is performed, and the liquid crystal molecules of the LCD are arranged parallel to the glass surface in the box. However, because the directional direction of the outer directional layer in the two glasses is straight to each other, the liquid crystal molecules of the LCD are distorted 90 degrees between the two glasses, which is the origin of the name of the twisted nematic liquid crystal exposure component.
