The development of technology so that the table stickers are no longer confined to the interior, began to rise outdoors and get a faster development. Table stickers are gradually improving in brightness, cost, gas tightness and other issues. With the rapid increase of chip height and the expansion of production volume, the problem will be solved gradually. Household appearance will gradually occupy the direct-insert lamp market share.
Compared to the direct-insert, the table-mounted LED display has more advantages:
First, a broad perspective
The exterior pastes the full color display not only in the horizontal direction has 140 degrees above wide angle of view, in the vertical direction also has more than 140 degrees wide angle of view, this in some application places especially has the superiority, for example the building screen, hangs in the high altitude outdoor LED display to need the broader angle of view to display the better advertisement effect.
Second, the light is good
Red, green, blue Oval led at different angles three kinds of brightness matching consistency is a very difficult indicator, and full-color SMD because the design structure for the triple structure, red, green, blue three chip all in a Bracket bowl cup, therefore in different angles red, green, blue three brightness match consistency height consistent, thus makes the outdoor Full-color table pastes LED display in any angle brightness horse consistent very good, achieves the better color realistic effect.
Third, mix up.
Because of the design structure of the triple, three chip distance is very near, in the same bracket bowl of mixed light, rather than three discrete elliptical led, so red, green, blue light effect is better than the straight insert oval LED screen, especially suitable for close viewing.
Forth,High Contrast
Because of the three-in-three design structure, full-color SMD size, so light area small, black area large, improve the contrast of LED display.
Fifth,Automatic production
SMD LED can use automatic SMT machine for automatic SMT, high production efficiency. LED household external display module of the line design can achieve the lamp plate and drive plate two, reducing costs, improve reliability, improve production efficiency. In addition, the automatic SMT production can improve the vertical precision of SMD on the PCB, overcome the vertical precision of the direct-insert elliptical led on the circuit board, so as to ensure better optical effect.
Previously, because of the low brightness of the SMD led, and waterproof, moisture-proof, anti-ultraviolet function does not reach the requirements of outdoor harsh environment, so outdoor full-color display is the world of direct-insert led devices. Full-color SMD LED display can only be used in a large number of households. With the LED chip technology and led packaging technology progress, SMD brightness and protection level has been able to meet the needs of outdoor applications, access to a more rapid application, I believe that the appearance of the household stickers will lead the future LED outdoor advertising screen market.
