Ordinary LCD screens use CCFL light sources, that is, cold-cathode fluorescent lamps (similar to the scanning lamps in the copy), with one on each side of the screen and a backlight on the back of the display, which is composed of fluorescent substances. The light sources on both sides can be evenly distributed on the back of the entire screen, so that the entire screen can be evenly illuminated. However, due to technical limitations, the brightness of such a display is not completely uniform, but it is difficult to find it. At the same time, the lamp also has a certain lifespan, and it will turn yellow after a long time.

TN LCD screen glass has high transmittance. Under the same backlight conditions, TN will have higher brightness. TN glass cost is relatively cheap, which is more cost-effective for customers with price requirements; IPS is better than TN in terms of viewing angle, display effect and other parameters, but the unit price is relatively higher. Customers need to choose according to the positioning of their products. Shenzhen Hongjia Technology specializes in the production of 1.14-inch to 10.1-inch LCD screens and matching touch screens. Both TN and IPS are available, with complete sizes and multiple interfaces. Customers are welcome to email for consultation.
