Lianjian Optoelectronics applied for a patent for "a method to improve the moisture-proof performance and ink color consistency of LED displays"

The patent summary shows that the present invention discloses a method for improving the moisture-proof performance and ink color consistency of an LED display screen, which includes the following steps: S1, upper plate, and place the PCBA lamp board stably in the coating operation area of the precision coating equipment; S2, nano surface spraying, the precision coating equipment performs automatic coating operations on the PCBA lamp board, and the material sprayed by the precision coating equipment is a nano-slurry formed by mixing the ink color and polymeric nano-fluorocarbon optical materials; S3, high-temperature curing, after coating The PCBA lamp board automatically flows into the high-temperature curing furnace through the assembly line, and is heated at 70±5°C for 15±3 minutes before flowing out; S4, detection; S5, lowering the board, placing the qualified PCBA lamp board flat on the turnover vehicle for later use. The invention combines coating and inkjet technologies into one, realizing a single process that can simultaneously improve the L moisture-proof and ink color consistency effects of the LED display screen, and is not limited by hardware equipment and product gap size, thereby improving production efficiency and reducing production costs.
