With the rapid development of the display industry, mini LED 3mm has become a popular term in the market. This article aims to introduce the concept, technology, and application of mini LED 3mm, providing a comprehensive overview of this cutting-edge technology.

Introduction to Mini LED 3mm

Mini LED 3mm refers to a type of LED display with a pixel pitch of 3mm. It is a new generation of display technology, which is smaller and more compact than traditional LED displays. Mini LED 3mm has been widely used in various fields, such as TVs, monitors, smartphones, and automotive displays.

Technology Background

Mini LED technology is based on the principle of LED (Light Emitting Diode) display. It utilizes a large number of mini-sized LEDs to form a picture. The main advantages of mini LED technology include high resolution, high contrast, and low power consumption. Compared with traditional LED displays, mini LED 3mm has the following features: 1. High resolution: Mini LED 3mm has a high pixel density, which can provide high-definition and clear images. 2. High contrast: The mini LED 3mm has a high contrast ratio, which can make the picture more vivid and realistic. 3. Low power consumption: Mini LED 3mm has a lower power consumption than traditional LED displays, which is more energy-efficient. 4. Flexible design: Mini LED 3mm can be designed into various shapes and sizes, meeting different application needs.

Manufacturing Process

The manufacturing process of mini LED 3mm involves several steps, including wafer slicing, epitaxy, packaging, and assembly. The following is a brief introduction to each step: 1. Wafer slicing: The wafer slicing process involves cutting the silicon wafer into thin slices. The thickness of the slice is usually around 200-300 micrometers. 2. Epitaxy: The epitaxy process involves growing a thin layer of LED material on the silicon wafer slice. This layer is typically made of gallium nitride (GaN) or aluminum gallium nitride (AlGaN). 3. Packaging: The packaging process involves encapsulating the LED chip with a package material, such as phosphorus silicon glass (PSG) or silicon nitride (SiN). This process helps to protect the LED chip and improve its heat dissipation performance. 4. Assembly: The assembly process involves mounting the packaged LED chip on a substrate, such as a printed circuit board (PCB) or glass substrate. This process forms a complete mini LED 3mm display module.

Application Fields

Mini LED 3mm has been widely used in various fields, including: 1. TVs: Mini LED 3mm technology has been applied to the production of TVs, which can provide high-definition, high-contrast, and low-power consumption images. 2. Monitors: Mini LED 3mm can be used to produce high-performance monitors, which are suitable for professional use and gaming. 3. Smartphones: Mini LED 3mm technology can be used to produce high-definition, high-contrast, and low-power consumption smartphone displays. 4. Automotive displays: Mini LED 3mm can be used to produce high-definition, high-contrast, and low-power consumption automotive displays, which are more conducive to driver concentration and safety.
