Features and arrangement of monochrome LCD display modules

[Summary description] The usual natural light is scattered randomly in all directions. The monochrome LCD module relies on the polarization filter and itself. The lines of the polarization filter are actually many and thinner. A web of parallel lines blocks all rays that are not parallel to it, or it matches the second, so that light can penetrate.

Under normal conditions, light is twisted 90 degrees after passing through the first filter. If a voltage is applied to the liquid crystal, the molecules will be rearranged in parallel again, so that the light is no longer twisted.

In general, if the electric light is added, there will be no light, and if the electric light is not applied, the light will appear. How do we make the light block the light when the power is applied? First of all, we can change the liquid crystal arrangement in the monochrome LCD module, so that the light can be emitted when there is electricity, but because the brightness of the computer screen is long-term, only adding resistance to cut off the light is the most power-saving purpose.

Because the liquid crystal material itself does not emit light, there are lamps on both sides of the display screen as light sources, and there is a layer of backlight behind it, the main function is to provide a uniform background light source.

As the principle of monochrome LCD screen display module, today I will briefly introduce it here. If you need to know other knowledge about this kind of knowledge, please click and follow.
