We must know a lot about LED displays. LED displays are actually screens that display information by light-emitting diodes (commonly known as “LED lights”). The use of light-emitting diodes (LEDs) to emit light independently is relative to the use of LEDs as backlight sources.
The LED displays/displays that we usually see used in TVs, computers, and mobile phones can’t actually become LED displays. They can only be LCD displays/displays that use LEDs as the backlight. Only LED displays that can emit light independently are What we need to know about the LED display is also a very important difference between the two.
After knowing the LED display screen, you will actually have a good understanding of the special-shaped LED display screen. Conventional LED displays are generally square or rectangular, while special-shaped LED displays can be made into various shapes, such as logo LEDs, according to actual conditions and better adapt to the overall structure and use requirements of the environment. Display screen, triangle display screen, DJ horn screen, etc. Generally speaking, it is roughly divided into the following categories:
1. LED spherical screen
You may not have thought of it. In fact, the LED spherical screen is also a kind of special-shaped LED display. Compared with the round shaped LED display, the LED spherical screen will have a more three-dimensional effect. It has the following characteristics:
1. The spherical LED screen is designed with an all-aluminum structure. The structure is very strong and durable. At the same time, it can be designed in a movable form and easy to carry. It can be installed in hoisting or seat mounting.
2. 360° full viewing angle, you can feel good visual effects at any angle when playing videos in all directions, without the problem of flat viewing angle.
3. It can be designed and produced according to customer requirements. The minimum diameter is 1 meter and can be used indoors and outdoors. The spherical surface is completely completed by CNC. The precise module size ensures the uniformity of the overall curvature of the LED spherical screen and makes the spherical shape look regular and uniform. Perfect.
2. Arc-shaped LED display
The display surface of the LED display is a part of the cylindrical surface, which can show the arc shape. The expanded view is a rectangle. Because it is a bit like a pillar, such a display is often used in shopping malls and subway stations as a decorative application scene.
2. Curved LED display
The display surface of the LED display is a three-dimensional curved surface, such as a naked-eye 3D outdoor large screen, a sky screen, etc.
3. Irregular LED display
The display surface of the LED display is an irregular plane, such as a trapezoid, a diamond, a five-pointed star or a completely irregular plane. The DJ horn screen we mentioned earlier is actually an irregular-shaped LED display.
4, triangular LED spherical screen
The ball screen composed of triangular LED spherical screen and flat triangular PCB is commonly known as football screen. The utilization rate of the screen is greatly improved. The disadvantage is that the variety of PCBs is limited by the honeycomb arrangement of pixels and the dot pitch cannot be too small.
The above categories basically cover most of the special-shaped LED displays on the market. The special-shaped LED displays that are already available on the market are cheaper than those without. If there are none on the market, this means that the mold and prototype need to be re-made, and the corresponding cost will be higher.
