Advantages Comparison Between Surface Matching Full Color LED Display and Straight Line Full Color LED
1. wide viewing angle Outdoor surface paste full color screen not only in the horizontal direction with more than 110 degrees wide viewing angle, in the vertical direction also has a wide viewing angle of 110 degrees, which in some applications are particularly advantageous, such as building screen, hanging in the high-altitude outdoor LED display Need a wider perspective to show better advertising results.
2. with good light. Red, green and blue oval LED in different angles three kinds of brightness matching consistency is a very difficult index, and full color SMD because the design structure for the triple structure, red, green, blue three chips all in the A stall cups, so in different angles red, green and blue three kinds of brightness matching consistency is highly consistent, so that the outdoor full color surface mount LED display at any angle the brightness of the match is very good, to more Good color realistic effect.
3. mixed light good. As the design structure for the triple, three chips from the very close, in the same bracket cup mixed with light, rather than three separate oval LED, so red, green, blue blending better than straight oval LED Screen, especially suitable for close viewing.
4, high contrast. As a result of three-in-one design structure, full-color SMD size is small, so the luminous area is small, black area, improve the LED display contrast.
5. automated production. Surface mount LED can use automatic placement machine for automated patch, high production efficiency. LED outdoor surface mount display module line design to achieve light board and drive board combo, reducing costs, improve reliability and improve production efficiency. In addition, automated patch production can improve the vertical accuracy of SMD on the circuit board, to overcome the vertical oval LED on the circuit board vertical accuracy problems, so as to ensure better optical results.
6. the box light weight. The use of aluminum alloy box structure design is very light; and beautiful and easy to deformation easy and smooth assembly. Suitable for leasing companies, LED rental screen, mobile media use; column installation or wall installation to reduce the screen on the steel structure of the pressure.
7. no irrigation. The traditional outdoor screen module filled with colloids in the sun and rain and ultraviolet radiation will gradually aging, colloidal characteristics will change after the split off, making the circuit board and LED lost protective layer, or even after a long time The heat will not reach the waterproof effect after cooling, and the glue will go through the gap into the screen body, the corrosion of the PCB board, affecting the life and stability of the whole screen; if it is a three-in-one outdoor paste filling process, Because the lamp is too short, irrigation is too thin, the consequences are more serious. Previously, due to the low brightness of the surface of the LED, and waterproof, moisture, anti-ultraviolet function can not meet the requirements of outdoor harsh environment, so the outdoor full color display is the standard LED device in the world. Full color surface mount LED display can only be used in a large number of indoor. With the LED chip technology and LED packaging technology advances, SMD brightness and protection level has been able to meet the needs of outdoor applications, access to a more rapid application.
