Now when installing LED displays, many friends will adopt the form of outdoor surface stickers. Today let us take a look at the advantages of outdoor surface brackets for LED displays.
1. Wide viewing angle: The full-color screen mounted on an outdoor surface not only has a wide viewing angle of 110 degrees or greater in the horizontal direction, but also a wide viewing angle of 110 degrees or greater in the vertical direction, which is particularly advantageous in some applications. , Such as building screens hung at high altitudes. Outdoor LED displays need wider viewing angles to display better advertising effects.
2. Good light distribution: red, green, and blue oval LEDs are matched consistently. The three brightnesses are a very difficult indicator at different angles. The full-color SMD is a three-in-one structure, red and green. The three blue chips are all in a holder cup, so the matching consistency of red, green and blue brightness at different angles is consistent, which makes the outdoor full-color surface LED display consistent at any angle. Very good, can achieve better color fidelity effect.
3. Good mixing: Because the design structure is three-in-one, the three chips are very close, mixed in the same bracket cup, instead of three discrete oval LEDs, so the mixed light effect of red, green and blue Compared with the linear oval LED screen, it is especially suitable for close viewing.
4. High contrast: Due to the three-in-one design structure, the full-color SMD is small in size, so the light-emitting area is small and the black area is large, which improves the contrast of the LED display.
5. Automated production: Surface mount LEDs can be automatically patched using an automatic placement machine, which has high production efficiency. The circuit design of the LED outdoor surface mount display module can realize the combination of the lamp board and the driver board, reduce costs, improve reliability, and improve production efficiency. In addition, automatic SMD production can improve the vertical accuracy of the SMD on the circuit board and overcome the vertical accuracy of the embedded elliptical LED on the circuit board, thereby ensuring a better optical effect.
6. Light weight of the cabinet: the aluminum alloy material cabinet structure design is light and handy; the appearance is not easy to be deformed, and the assembly is convenient and even. Suitable for rental companies, car screens, mobile media; column installation or wall installation to reduce the pressure on the steel structure of the screen.
7. No filling glue: The glue filled in the traditional outdoor screen module will gradually age under the sun, rain and ultraviolet rays. When the characteristics of the colloid change, it will crack and fall off, which makes the circuit board and the LED lose its protective effect. This layer cannot achieve waterproof effect even after a long time of heat rise and shrinkage, and the glue will enter the screen through the gap, which will corrode the PCB board and affect the service life and stability of the entire screen; if it is an outdoor three-in-one surface If the glue filling process is used for placement, the result will be more serious because the lamp feet are too short and the glue is too thin.
The advantage that outdoor surface stickers bring to full-color LED displays is that it is for these reasons that so many people like this method.
