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

How Does An LCD Screen Work? Answering A Liquid Crystal Display Tech Question #LCD #Tech   You can find Liquid Crystal Display (LCD) technology everywhere: in TVs, computers, tablets, laptops, smartphones, watches, monitors, displays, calculators, cellphones, smartwatches, and many more… but do you know how this awesome tech works? Do you also know that the working principle of LCD is pretty similar to the newer LED backlit based screens (edge LED or direct LED)? So today, we explain how an LCD screen work by looking inside an LCD screen and detailing all of its layers. We will talk about the reflector sheet, the Light Guide Plate (LGP), the Dual Brightness Enhancement Film (DBEF), the diffuser sheet, the prism sheet, the bottom polarizer, the bottom glass substrate (backplane), the Thin Film Transistor (TFT), the Liquid Crystal, the Common electrode, the color filter (RGB), the top glass substrate, the top polarizer, and the top chassis and frame. Understanding how a screen works can be especially handy to know if you like clever technology or to understand if your screen breaks down, and you need to figure out what is going on to repair it… knowledge is power!

This video showcases two different types of glass used in outdoor machines: tempered glass and AR laminated glass. Both types were subjected to impact testing and smashed to demonstrate their differences.Firstly, let’s take a look at tempered glass. While it’s stronger than regular glass, it can still shatter under strong impact. When tempered glass breaks, it splits into small pieces that may cause harm to people nearby. By contrast, AR laminated glass offers superior safety performance. It uses a polymer interlayer to bond two sheets of glass together, which ensures that even if it breaks, the glass fragments adhere tightly to the polymer. This means shattered glass won’t fly around and is easier to clean up. As a result, AR laminated glass is widely used in situations where high safety is required, such as car windows and building exteriors. Through this test, we demonstrated how the two types of glass break differently. We hope this video provides useful information to help you better understand different types of glass. https://youtu.be/60wnYg0ubzs
