Liquid Crystal Inside TN/HTN LCD Screen With White Background And Black Characters

Most of the liquid crystal exposure components used in pen segment digital displays are TN or HTN LCD screens.

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

The exposure component of the LCD screen is a common liquid crystal LCD display. The common wrist watches, digital instruments, electronic clocks and most of the liquid crystal exposure components used in calculators are TN/HTN type LCD screen components. Because of this, this component should be the LCD LCD liquid crystal exposure device that many people know well

Twisted nematic phase (TN) is exposed because a layer of directional layer film is coated on the inside and outside of the glass of the LCD LCD screen, and directional treatment is carried out. In the box, LCD liquid crystal molecules are arranged in parallel along the outside of the glass. However, because the orientation of the directional layers on the inner and outer surfaces of the two glasses is vertical to each other, LCD liquid crystal molecules twist 90 ° between the two glasses, which is the origin of the name of the exposed parts of twisted nematic liquid crystals.
