What are the advantages of the outdoor LED display over the in-line type?

In the past few years, outdoor LED displays almost all use inline oval red, green, and blue LED devices, and in recent years, outdoor full-color LED displays with pixel spacing of 2.5mm to 10mm are gradually emerging and widely used.

First, a wide perspective. The household surface pasted full color screen not only has a wide Angle of view of more than 110 degrees in the horizontal direction, but also has a wide Angle of view of more than 110 degrees in the vertical direction, which is particularly advantageous in some applications, such as building screens, outdoor LED displays hanging at high altitude need a wider Angle of view to show better advertising effects.

Two, good distribution of light. Red, green, blue oval LED in different angles of three brightness matching consistency is a very difficult indicator, and full-color SMD because the design structure is a three-in-one structure, red, green, blue three chips are all in a bracket bowl, so in different angles of red, green, blue three brightness matching consistency is highly consistent, Thus, the brightness consistency of the outdoor full-color table sticker LED display at any Angle is very good, to achieve better color fidelity.

Three, good mixing light. Because the design structure is three-in-one, the three chips are very close, and the light is mixed in the same bracket bowl, rather than the three discrete oval LED, the red, green and blue light mixing effect is better than the straight insert oval LED screen, especially suitable for close viewing.

Four, high contrast. Due to the three-in-one design structure, the size of the full-color SMD is small, so the luminous area is small, the black area is large, and the contrast of the LED display is improved.

five, Automated production. Surface mount LED can use automatic mount machine for automatic mounting, high production efficiency. The circuit design of the outdoor LED display module can realize the light board and the driver board in one, which reduces the cost, improves the reliability and improves the production efficiency. In addition, the automated patch production can also improve the vertical accuracy of SMD on the circuit board, overcoming the vertical accuracy problem of the in-line elliptical LED on the circuit board, thus ensuring better optical effects.

Six, the box weight is light. Aluminum alloy box structure design is very lightweight; And beautiful, not easy to deform, easy to assemble and smooth. Suitable for rental companies, car screen, mobile media use; Column installation or wall installation also reduces the pressure of the screen on the steel structure.

Seven, no glue. The colloid filled by the module in the traditional outdoor screen will gradually age under the sun and rain and ultraviolet irradiation, and the characteristics of the colloid will split off after changing, making the circuit board and LED lose the protective layer, and even after a long time of thermal expansion and cold contraction, the waterproof effect can not be achieved, and the glue will enter the screen through the gap, which has a corrosive effect on the PCB board. Affect the life and stability of the whole screen; If it is a table paste outdoor three-in-one gluing process, because its lamp foot is too short, gluing is too thin, the consequences are more serious.

In the past, because the brightness of the table sticker LED is low, and the functions of waterproof, moisture-proof, and ultraviolet protection can not meet the requirements of the outdoor harsh environment, the outdoor full-color display is generally the world of direct-plug LED. Table sticker full color LED display can only be used in a large number of indoor applications. Recently, with the advancement of LED chip technology and LED packaging technology, the brightness and protection level of SMD have been able to meet the needs of outdoor applications, and have obtained a faster application.
