IPS is the abbreviation of In-Plane Switching in English. The English meaning is in-plane switching hard screen technology, commonly known as "hard screen". It is the most advanced LCD panel technology in the world. Like wearing glasses. Generally, more mainstream mobile phones will use IPS screens, which have excellent display effects, so it has become one of the major selling points of many mobile phones.

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.

In today's consumer electronics industry, both technologies are widely used, often appearing in the same device. For example, in an ultra-thin laptop, the main connection between the motherboard and screen might use direct gold-finger connectors for the sake of thinness, while the connections between the motherboard and components like the touchpad and keyboard might use traditional connectors. If reliability and maintainability are more important than saving a fraction of a millimeter in thickness, then connectors are a more reliable and mature choice. If you are building an ultra-thin, cost-sensitive new product with a high-precision automated production line, you should carefully consider the direct gold-finger connector solution.

In order to meet the increasing number of new orders, Shenzhen Hongjia Technology added a fully automatic TFT screen production equipment to the factory on November 25, 2024, including one-stop feeding such as glass cleaning, COG bonding, FOG bonding, backlight assembly, etc. before production.
