FM TC7260 – 8-Channel LED Display Line Scan Blanking Control Driver IC
The FM TC7260 is a high‑performance driver IC designed specifically for LED screen line‑scan displays. Manufactured by Shenzhen Fuman Electronics Co., Ltd. (FM), this chip integrates a line blanking circuit, a 74HC138 3‑8 decoder, and built‑in power tubes into a single SOP‑16 package, making it an ideal solution for high‑quality, high‑refresh‑rate LED display modules.
If your LED display panel is suffering from ghosting (smear), caterpillar artifacts caused by LED leakage, or uneven brightness due to scanning issues, replacing the row‑driver IC with an original FM TC7260 is the most effective fix. This chip is engineered to eliminate common scanning artifacts and improve overall display uniformity.

Why Your LED Display Needs the FM TC7260
The FM TC7260 is built to solve the most common image quality problems in line‑scan LED display systems:
- Eliminates Ghosting (Smear) – When the power tube is turned off, the internal pull‑down tube of the TC7260 opens and absorbs residual charge on the row line with a constant current, completely removing ghosting artifacts.
- Removes Caterpillar Artifacts – The unique patented technology of the TC7260 actively suppresses the caterpillar effect caused by LED leakage and short circuits, which is common in aging display panels.
- Integrated 3‑8 Decoder – The built‑in 74HC138 decoder reduces external component count and simplifies PCB layout.
- High Current Drive – With 8 integrated power tubes delivering up to 3.5A peak current and an ultra‑low 110mΩ on‑resistance, the TC7260 can drive large LED panels without external buffer transistors.
- Built‑in Protection – The anti‑burnout power tube design, along with over‑current and short‑circuit protection, ensures long‑term reliability in demanding 24/7 operation environments.
- Proven Performance – The TC7260 is widely adopted by LED display manufacturers and is considered one of the best chips on the market for achieving clean, high‑contrast scanning effects.
Typical Symptoms That Indicate a Faulty Row‑Driver IC
If you are experiencing any of the following issues with your LED display, the row‑driver IC (such as the TC7260) may be failing:
- Ghosting or smearing – A faint residual image or “shadow” trails behind moving content, most visible during high‑contrast transitions.
- Caterpillar artifacts – Bright or dark lines that appear along scan lines, typically caused by LED leakage or short circuits within the driver circuit.
- Uneven brightness across scan lines – Some rows appear dimmer or flicker compared to others, indicating inconsistent row drive current.
- Completely dead scan lines – One or more rows of the LED display fail to illuminate at all, often due to a failed driver IC channel.
- Visible scan lines at lower refresh rates – A line‑by‑line scanning effect becomes visible to the naked eye, usually caused by timing issues in the driver IC.
Replacing the old or failed driver IC with an original FM TC7260 restores proper scanning timing, eliminates artifacts, and extends the operational life of your LED display.
Typical Applications
The FM TC7260 is the ideal choice for any LED display system that requires high‑refresh scanning and artifact‑free image quality:
- Full‑color LED display modules – The chip is commonly used as a row‑driver in P2.5 to P10 full‑color LED panels.
- Indoor & outdoor LED video walls – Designed for 24/7 operation in advertising screens, stadium displays, and rental LED panels.
- Digital signage & public information displays – Ensures high visibility and consistent image quality in transportation hubs, retail spaces, and corporate lobbies.
- Transparent & flexible LED screens – The SOP‑16 package and integrated decoder simplify the design of space‑constrained creative LED installations.
Restore Your LED Display – Not the Whole System
When a line‑scan driver IC fails, the symptoms can mimic a full panel failure. However, replacing a single faulty TC7260 chip is often the only repair needed to restore complete functionality. If you have already ruled out power supply issues, loose cable connections, and data transmission problems, the row‑driver IC is a prime suspect. Replacing it with this genuine FM original part ensures compatibility, reliability, and long service life.
