Description
Royal and started the product development, production, sales of LED
backlight since 2007.
Our backlight widely used in control panel,dashboard, and other indicators with MONO LCD display
Tooling SMD LED Backlight with a Custom Mold
LED backlight is used to light LCD,so that LCD graphics can be seen
clearly on the dark environment or at night.
Usually,The LED backlight that we said was side-LED backlight.
Side-LED backlight can be separated into two types: SMD LED
backlight and DIP LED backlight (direct insertion probe).
1.LED Backlight size: LED backlight size will be decided by LCD
size. Usually,LED backlight should be longer than LCD,because LED
backlight needs a 7-8mm covering area to covering LED.
2.LED backlight color:
LED backlight colors just have
white,blue,green,red,orange,amber,yellow and so on. All colors are
confirmed by LED colors. You can't specify a special color or send
us Pantone color, (Maybe there is no this kind of LED)
If LCD need kinds of colors,then you can use RGB LED backlight. But
RGB LED color is not very pure.
3.Connector: pins.
Pin pitch 2.54mm,;Pin diameter 0.4mm.
Pins should be inserted into PCB holes ans solder them.
SMD LED backlight specifications:
SMD LED backlight means LEDs are bonded on the PCB.So it is
necessary to make PCB mold
1) LED Backlight size: LED backlight size will be decided by LCD
size. Usually,LED backlight should be longer than LCD,because LED
backlight needs a 5-6mm covering area to covering LED.
2)LED backlight color:
LED backlight colors just have
white,blue,green,red,orange,amber,yellow and so on. All colors are
confirmed by LED colors. You can't specify a special color or send
us Pantone color,then ask us to follow it. (Maybe there is no this
kind of LED)
If you need kinds of colors,then you can use RGB LED backlight. But
RGB LED color is not very pure.
3)Connector:
Wires connection:solder wires on the PCB
PCB Pin connection:PCB pin should be inserted into PCB and solder
it.
4)LED numbers:
If LED backlight size is very big,maybe it is necessary to use 2
LED,3 LED,4,5.........
If LED backlight is too long,we should install LED at both side of
backlight.
5)LED voltage:
White LED,blue LED,green LED is 3.0-3.2V
Red LED,orange LED,yellow-green LED etc are 1.9-2.0V
