Characteristics of Several Different LED Display Modules
2019 / 02 / 28
According to the different surface treatment technology of LED display screen, we can divide it into plug-in module, table-mounting module, sub-table-mounting module, three-in-one table-mounting module and three-in-one table-mounting module. Plug-in module It refers to the DIP encapsulated lamp which passes the lamp foot through the PCB board and fills the tin in the lamp hole by welding. The module made by this process is the plug module. The advantages are large angle of view, high brightness and good heat dissipation. The disadvantages are low pixel density. Surface mount module SMT, also known as SMT, solders the SMT encapsulated lamp on the surface of PCB board by welding process, the lamp foot does not need to pass through the PCB board, and the module made by this process is called SMT module. The advantages are: large perspective, soft display image, high pixel density, suitable for indoor viewing; the disadvantages are that the brightness is not high enough, and the lamp tube itself does not heat well. Subsurface Mounting Module It is a product between DIP and SMT. The packaging surface of LED lamp is the same as SMT, but its positive and negative pins are welded through PCB in production as DIP. Its advantages are high brightness, good display effect, and its disadvantages are complex process and difficult maintenance. Three-in-one table sticker It refers to encapsulating three different colours of LED wafers, R, G and B, in the same colloid. The advantages are: simple production, good display effect, and disadvantage: difficult spectrophotometry and high cost. Three-in-one sticker It refers to the vertical juxtaposition of three independent packaged SMT lamps, R, G and B, according to a certain distance, which not only has all the advantages of the three-in-one, but also solves all the disadvantages of the three-in-one. From the above classification, we can see that diffe

IP Protection Level of LED Display Screen
2019 / 01 / 08
The IP (International Protection) protection level system for LED display screen was drafted by IEC (International Electro Technical Commission). The lamps and lanterns are classified according to their characteristics of dust-proof, foreign invasion-proof, waterproof and moisture-proof. The objects referred to here include tools, human fingers and so on. They can not touch the charged part of the lamp, so as to avoid electric shock. IP protection level is composed of two numbers. The first number represents the level of dust-proof and foreign invasion prevention of lamps and lanterns, and the second number represents the degree of sealing of moisture-proof and water-proof invasion of lamps and lanterns. The bigger the number, the higher the level of protection. The two numbers indicate the level of protection as follows: IP protection level: The first indication of the degree of protection indicated by the characteristic number (number) The first number is: 0 unprotected IP0- 1. Prevent solid objects larger than 50mm from intruding and human body (such as palm) from accidentally touching parts inside lamps. Prevent large size (diameter greater than 50mm) objects from intruding into IP1- 2. Prevent solid objects larger than 12 mm from intruding into the lamp and prevent human fingers from touching the parts inside the lamp. Prevent medium-sized (diameter greater than 12 mm, length greater than 80 mm) objects from intruding into IP2- 3. Prevent the intrusion of solid objects larger than 2.5mm, tools, wires or similar small objects larger than 2.5mm in diameter or thickness from touching the interior parts of lamps IP3- 4. Prevent the intrusion of solid objects larger than 1.0 mm, tools, wires or similar small objects larger than 1.0 mm in diameter or thickness from touching the interior parts of lamps and lanterns IP4- 5 Dust-proof, completely prevent foreign invasion.
