This diffused RGB backlight is a rigid acrylic light panel like the kind normally found behind LCD displays, but with a full-colour LED instead of a plain white backlight. The acrylic spreads the light from a single LED to give a near-uniform glow across the lit area.
The flat rear side includes a reflector, so light is directed out of the top surface rather than being wasted out the back. You can mask it with vinyl or draw on it with a marker to create illuminated shapes, labels or display effects.
It can be driven like a common-anode RGB LED: connect the longest pin to 3~5VDC, then connect the red, green and blue pins through suitable series resistors to ground. Each colour channel should be limited to no more than 20mA.
These make a bright alternative to EL panels for wearable projects, signage and small illuminated interfaces, without needing an inverter. The trade-off is that the panel is not flexible.
Specifications:
- Lit area: 1.7" by 3.3" (45mm x 84mm)
- Acrylic strip thickness: 3.3mm
- LED type: RGB LED variant
- Anode pin: Longest pin
- Anode supply: 3~5VDC
- Red, green and blue pins: Connect through resistors to ground
- Maximum current per colour: No more than 20mA
- Flexibility: Not flexible
Jargon buster
Plain-language definitions for the technical terms used above.
- common-anode
- A wiring arrangement where several LEDs or LED segments share a common positive (anode) terminal and are switched individually on their negative (cathode) side. Common-anode and common-cathode parts, such as RGB LEDs, seven-segment displays, matrices and strips, are not interchangeable without a suitable driver.
- LCD
- LCD stands for liquid crystal display, a screen technology that uses a backlight and liquid crystals to show images or text. It matters because LCD modules usually need a display driver and enough controller pins or a bus interface to send image data.
- LED
- A light-emitting diode (LED) is a small electronic component that emits light when current flows through it in the correct direction. Because it only conducts one way, its polarity matters, and a through-hole LED must be soldered the correct way around to light up.
- RGB
- Short for red, green and blue, the three primary colours of light that are mixed in varying amounts to make a wide range of colours. In electronics RGB can refer to an LED or pixel that blends these three colours, or to a colour signal or interface that carries separate red, green and blue channels.
