Programmable Full-Colour LED Sign 7x17cm USB Flexible Matrix for Car and Wall

This programmable LED matrix panel is a compact, full-colour display designed for showing custom text, patterns, and animations. It uses a 16x32 resolution LED matrix and a 7x17cm screen, with additional format options listed as 12x47cm, 12x59cm, 12x68cm, and 9.2x37.2cm. The panel connects through a USB plug and is controlled by a smartphone app, so you can change messages and adjust brightness and speed without extra equipment. The flexible circuit board can be bent and folded, which allows mounting on walls or other objects where a flat rigid screen may not sit easily. This makes it suitable for car windows, shop displays, and other indoor signage where a small, bright, full-colour screen is useful.

Features and Construction

The panel is built around an LED matrix and a flexible circuit board. It is described as thin and light, with a USB plug for power and app-based control. These construction details support its use as a portable, adaptable display rather than a fixed sign.

Material and Build

The LED matrix provides full-colour output and is stated to have high-intensity light with low power consumption. The flexible circuit board allows the panel to be bent and folded, which is useful when attaching it to curved or uneven surfaces. The USB plug design removes the need for a separate power adapter in the source description, though the exact power requirements are not given. The panel is described as ultra-thin, which helps when mounting it on walls, windows, or other objects where space is limited.

Size and Practical Fit

The screen size is 7x17cm, with a resolution of 16x32. The option list also includes 12x47cm, 12x59cm, 12x68cm, and 9.2x37.2cm formats. These sizes are suited to close-range viewing, such as in a car window or on a shop counter. The flexible build means the panel can be shaped around objects to some extent, but no minimum bend radius or maximum fold limit is provided. For larger displays, the bigger format options may be more suitable, though full specifications for each size are not listed.

Uses and Placement

The panel is intended for displaying custom text, patterns, and animations in a range of settings. Its USB power and app control make it practical for temporary or semi-permanent indoor signage where messages need to be changed regularly.

Event or Professional Use

For shop windows, market stalls, or event signage, the full-colour LED matrix can show scrolling text or simple animations to attract attention. The app control allows messages to be updated on site without reprogramming hardware. The 7x17cm size is best for close viewing, while the larger format options may suit bigger displays. No waterproof rating is given, so the panel should be kept dry unless additional protection is provided.

Everyday Home Use

At home, the panel can be used for room signs, party messages, or decorative animations. The USB plug allows it to be powered from a laptop, power bank, or USB wall adapter, though the source does not specify compatible power output. The flexible circuit board can be attached to walls or other objects, and the thin design helps it sit discreetly. Brightness and speed can be adjusted through the app to suit different rooms or times of day.

Benefits and Buying Value

The main practical benefits come from app-based control, full-colour output, and a flexible, lightweight build. These features support reuse and easy message changes without needing to replace the display.

Reuse and Low Maintenance

Because the text, patterns, and animations are designed through the app, the same panel can be reused for different messages or events. There is no need to print new signs each time. The LED matrix is stated to have low power consumption, which may help with running costs, though no exact wattage is provided. The flexible circuit board and USB plug design keep the unit portable and easy to reposition. No specific maintenance instructions are given in the source, so cleaning should be limited to a dry or slightly damp cloth, avoiding water ingress.

Why Choose This Product

This panel is a practical choice for anyone who needs a small, customisable, full-colour LED display with app control and flexible mounting. The 16x32 resolution and 7x17cm screen size are suited to close-range signage, and the option list includes larger formats for different needs. The USB plug and bendable circuit board add portability and placement flexibility. No claims are made about waterproofing, battery life, or outdoor durability because the source does not provide that data. Buyers should check the format option they need and ensure they have a suitable USB power source.
