LCD polarizer for LCD module

The full name of a polarizer should be a polarizer. Those who have studied physics should know what polarized light is. The imaging of a LCD screenmust rely on polarized light. All liquid crystals have two front and rear polarizers attached to the liquid crystal glass to form a total honesty. Liquid crystal film of about 1mm. If any polarizer is missing, the liquid crystal film will not be able to display images. The reason why the polarizer is replaced by the polarizer is that the polarizer facing the eyes of the ordinary LCD screenis frosted to dissipate the surface reflection and diffuse the light to increase the viewing angle of the liquid crystal display. For the projector, any scattering will cause the loss of light. The ideal state of the liquid crystal film used in the projector should be a 0 degree viewing angle, that is, when the liquid crystal film is viewed from the vertical direction, there is no light. Of course, this is impossible to achieve, but the closer the viewing angle is to 0 degrees, the higher the light utilization rate, so after replacing the frosted polarizer with a flat polarizer, the brightness of the projector to the wall will be greatly improved. My personal estimate is that it can increase by 50-80%, which is why the polarizer should be changed. Polarized lenses Standard polarized lenses are globally recognized as the most suitable lenses for driving. When the light is reflected from the surface of the object, it has been partially polarized to produce glare. The opposite effect of glare--enhance brightness and weaken color saturation; make the contours of objects blurred and make the glasses tired and uncomfortable. The polarizer is made according to the polarization principle of light, and has the special function of effectively eliminating glare, so that the driver can improve the vision and increase the driving pleasure.
