These bright white LED panels are the same sort used in backlights for LCD displays, usually tucked just behind the display. The LEDs are encased in acrylic to produce a beautifully even light, and there's a foil reflector behind to maximise the light bounced forward.
Use gels or even marker pens on the acrylic to change the colour of light produced. Get creative and use these panels in your wearables project; they're much less power-hungry than EL wire or panels and don't need an inverter (although they aren't flexible like EL lights).

Plain-language definitions for the technical terms used above.
- 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.
