How to construct a liquid crystal display system Character LCD Module

The surface of the liquid crystal layer having the liquid crystal orientation structure. This orientation layer is obtained in a layer of an organic polymer film (polyimide), high-speed friction with a flannel material. You can think of it as some groove, some of these slots is very wide, and does not work, but some groove width and the width of the liquid crystal is similar, so that you can play the role of the fixed orientation of the liquid crystal molecules. After manufacturing a liquid crystal layer poured into a liquid crystal alignment layer surface, the major axis of the liquid crystal nature is aligned with the alignment layer on the friction direction. This fixed orientation of the liquid crystal molecules is the first step in the manufacture of liquid crystal displays. Now, this additional layer fixed to the surface after the nematic liquid crystal layer is built up. Under a layer of liquid crystal molecules will be spread above this layer of liquid crystal. Like this, the first layer of liquid crystal molecules in a fixed alignment shop on the alignment layer, laid on the first layer, the second layer of liquid crystal molecules gradually accumulate and form a perspective view of the liquid crystal layer, the formation of such rules nematic.OLED Display
Now let's look at the structure of twisted nematic liquid crystal display. The liquid crystal molecules are aligned in the bottom surface of the orientation layer, the molecular long axis direction is perpendicular to the paper surface. With a twist of 90 °, while at the top of the liquid crystal molecules in the major axis direction is parallel to the drawing. However much discussion of the 90 ° twist. This distortion is a mechanical distortions, not the rotation of the polarization plane.
A space can be divided into different regions, each region can control electric field, these different areas called pixels or called sub-pixels. Can be placed behind each of the sub-pixels, the color filters of different colors can be obtained when the light through. When put red, green, and blue color filters, can be composed of a full-color display.Lcd display module
