A strip of 5050 RGB LEDs that sticks to the back of the TV, sips power from its USB port and throws a coloured halo on the wall that breathes with the soundtrack.
The MATICOD backlight is a length of 5050 RGB LEDs on sticky tape, sized to run around the back edge of a TV. The short version covers 32–43in sets with 9.84ft of strip and 54 LEDs, while the long one stretches to 16.4ft with 90 LEDs for screens from 55 to 70 inches. Both paint the wall behind the picture instead of shining into your eyes, so the room feels lit while the screen stays the star.
That soft wall wash does more than look pretty. Light on the wall behind a screen softens the jump from a glowing picture to a pitch-black room, which is why MATICOD pitches it against tired eyes in the dark. Set a low warm white for film night, or let it drift through colours when friends come over for a game.
Each 5050 package holds a red, a green and a blue chip under one lens, and mixing the three gives the 16 million shades the duoCo Strip app offers. The strip is plain RGB rather than RGBIC, so the whole run glows one colour at a time and shifts together. That calmer look suits a TV: no rainbow racing around the frame during a quiet scene.
The short set's draw sits well inside what the USB port on the back of most televisions supplies. A basic USB 2.0 port gives about 2.5W, so the 5W long set can outrun it; if that one flickers or dims, a 5V phone charger rated 1A or more is the steadier feed.

Tap mic mode in duoCo Strip and the controller listens to the room through its own microphone. Colours jump and brightness swells with whatever the speakers play, from a film score to a match crowd to a party playlist. No cable runs to the soundbar or the TV, which means a record player across the room drives it just as well.
A separate music mode takes its cue from the phone's own songs instead. The two feel different on a party night:
More than 21 dynamic patterns run from slow breathing fades to sharp colour jumps, and a speed slider sets how frantic they feel. Timing mode switches the strip on at dusk and off after the late show, so it doubles as a gentle night-light.
Three ways to drive it keep the whole sofa happy. The phone handles colour picking and scenes, the remote lives on the armrest, and the 3-key inline controller still works when both have vanished under a cushion.
Installation takes one clean surface and a few minutes. Wipe the back panel so it is dry and free of dust, peel the protective paper, then press the strip along the rear edge a little way in from the frame. The light should land on the wall, not leak past the bezel toward the sofa.
Screens hung on a bracket glow best, since the wall sits close behind the panel and catches the light evenly. A TV on a stand in front of a wall still glows, just in a wider, softer patch. Corner units and screens far from any wall show less, since the light has nothing close by to bounce from.
Many televisions cut power to their USB ports when they switch off, so the strip goes dark with the picture. That is perfect for a pure backlight. If the glow should linger as room ambience after the credits, plug the USB lead into a wall charger and let the timer end the evening.
Picking between the two MATICOD sets comes down to screen size. The 9.84ft kit suits 32–43in TVs in bedrooms, dorms and gaming corners; the 16.4ft kit adds 36 more LEDs and a 24-key remote for 55–70in living-room screens. A short set on a big TV lights only part of the back, and a long set on a small TV leaves spare strip with nowhere to hide.
Three other backlights suit the same spot with a different mood:
Before ordering, run a tape around the rear panel instead of trusting the diagonal alone, because bezels, stands and soundbars change how much strip fits. Check where the USB port sits and whether it stays powered in standby. Decide, too, whether a calm single-colour glow or a rainbow chase suits the room, since that choice points to RGB or RGBIC.
Gift shoppers can go by room: the short set for a teenager's bedroom TV or a dorm screen, the long one for the family set in the lounge. Both arrive ready to plug in, with nothing to solder and no mains adapter to hide, because a USB port does the powering.
No. Any 5V USB source works, including a phone charger or power bank. The TV port is simply the tidiest option and, on many sets, switches the lights off with the screen.
A 50in screen measures roughly 11ft around its back edge. The 16.4ft set covers that with slack to loop away, while the 9.84ft set leaves a gap along one side.
No. Sound drives it, through the controller's microphone or the phone's music, while the image plays no part. Screen-matching kits need a camera or an HDMI sync box.
The LED controller broadcasts that name. Connect from inside duoCo Strip, not from the phone's Bluetooth settings, and the strip shows up in the app's device list.
