LCD brightness and LCD backlight requirements

LCD brightness Brightness represents the amount of brightness of a picture per unit area. Specifically, the density of the amount of light passing through the normal direction of the screen. The unit is [CD / m2] or nit(1 nit = CD / m2).Brightness depends on the amount of light passing through the LCD and color film, and the brightness of the backlight.   LCD backlight requirements: The liquid crystal should have good transmittance; light weight; It should be thin and not easy to damage; The area light source with uniform brightness is the best; Low cost; The light color is pleasing to the eye, the primary color is rich, and the brightness can be adjusted; Low power consumption and easy power supply

What are the basic components of LCD?

We will use some electronic devices in our life, LCD module is one of the electronic components. Everyone’s understanding of it must be relatively strange, and then we will talk about the knowledge in this respect.   The following is an introduction to the three basic components and features of LCD. Let’s take a look with the editor: Liquid Crystal Materials Liquid crystal material is the main body of liquid crystal display. Different devices use different liquid crystal materials. Most liquid crystal materials are composed of several or even more than ten kinds of single liquid crystal materials.   Polarizer The light sheet, also known as polarized light, is made of plastic film material, coated with a layer of optical pressure sensitive adhesive, which can be pasted on the surface of the liquid crystal cell. There is a protective film on the surface of the front polarizer, which should be removed when using. The polarizer is afraid of high temperature and high humidity, which will depolarize or blister under high temperature or high humidity conditions.   Glass Substrate A kind of float production thin glass sheet with extremely flat surface, the surface of which is evaporated with a layer of zn203 or sn02 transparent conductive layer, i.e. ITO film, is processed into transparent conductive pattern. If scratched, cut or corroded, the vacuum device will be scrapped.
