COB contrast SMD led display screen:
1: Production Effeciency
COB :Efficiency and traditional SMD quite solid crystal, wire,
suffix point glue, separation, spectral, packing efficiency higher
than traditional SMD.
SMD :The production efficiency is lower than COB encapsulation
2: Application
COB: No need for SMT and reflow soldering process, COB light source
directly applied on the lamps and lanterns.
SMD :LED devices need to patch, and then fixed by means of reflow
soldering on the PCB board.
3: The quality of light
COB:Perspective and easy to adjust, in order to reduce the loss of
the refraction of light.
SMD:Discrete device combination point of light and glare.
Supermarket goods shelf led display.First LED all digital shelf
edge technology capable of delivering dynamic pricing
,promotion,product and brand related information at the shelf
edge.High resolution and standard module size.COB Screen Can
Shockproof&Waterproof&Dustproof and can wiped with rag when
it is splashed,hammer to knock and watering cabinet surface.It is
very easy to installtion and connection.Revolutionary design with
magnet&shackle.No tool,quickly install and remove.
COB LED shelf display screen advantage :
1: the thickness from 2.0 ~ 2.0 mm thickness of PCB, the least
weight reduced to 1/3 of the original traditional products, can
significantly reduce the structure for the customer,
transportation, and engineering cost.
2: Anti-collision compressive: COB products are directly to the LED
chips encapsulation inside the concave lamp of PCB, and then
encapsulated with epoxy resin adhesive curing, lamp bump into
spherical surface, smooth and solid, resistance to wear.
3: Great perspective: COB encapsulation using spherical shallow
Wells, Angle is greater than 175 degrees, close to 180 degrees, and
has more excellent optical diffuse color into light effect.
4: Heat dissipation ability: COB products is to encapsulate the
lamp on the PCB board, through the copper foil on the PCB board
will wick fast heat, and the copper foil thickness of the PCB board
has strict technical requirements, almost will not result in a
serious light attenuation.So few dead lamp, prolong the life span
of the LED display.
5: Easy to clean, no mask, dust or cloth to clean with water.
6: All-weather fine features: using triple inoculation, waterproof,
moisture, corrosion, dust, static, oxidation, uv effect is
outstanding;Meet the all-weather conditions, when it's minus thirty
degrees to 80 degrees centigrade temperature environment can be
normal use.
