From the perspective of packaging, I divide LED display screens into three eras: small spacing, Mini, and Micro. Different packaging eras have different product forms for LED display devices.

When displaying at small intervals, there are several typical forms of packaged devices:

1. Single pixel 3-in-1 separation device SMD: 1010 is a typical representative;

2. Array packaging separation device AIP: Four in one is a typical representative;

3. Surface gluing GOB: SMD room temperature liquid gluing is a typical representative;

4. Integrated packaging COB: Typical representative is room temperature liquid adhesive.

In the era of MiniLED, there are two main types of product forms: multi in one separation devices and integrated packaging.

Taking SMT as a typical representative is a multi in one and separate device; The typical example of physical module splicing is integrated packaging. Integrated packaging technology currently faces issues such as ink and color consistency, yield, and cost, while the 0505 separation device is already at the limit of SMD. Currently, it mainly faces issues such as reliability, SMT efficiency, and thrust. In the era of MiniLED, it may have lost its mainstream technology. In the era of MicroLED, there is no doubt that it will be integrated packaging, but the focus of the problem will be on chip transfer.

As for predicting the future technological trends of LED displays, I believe there are mainly four points:

1. Packaging technology has evolved from point technology packaging to surface technology packaging. Faced with LED miniaturization, this will be a path to reduce manufacturing processes and system costs.

2. From One in one, Four in one to N in one, the packaging form is simplified and simplified.

From the perspective of chip size and point spacing, there is no doubt that it is transitioning from Mini LED to micro LED.

From the perspective of the terminal market, in the future, LED display screens will shift from the engineering and rental markets to the commercial display market, shifting from display "screens" to display "devices".
