If your television is showing dark patches, flickering, or has lost brightness, the issue may lie in the LED backlight strips. Replacing them is often more cost-effective than buying a new TV, but the most common question people ask is: what size backlight strips do I need for my TV? Choosing the correct size ensures compatibility, proper brightness, and safe operation.
Backlight strips are designed to match the dimensions and optical layout of a specific TV model. Using the wrong size can cause:
Misalignment of light across the panel
Inadequate or uneven brightness
Poor fit with connectors or mounting holes
Risk of overheating or early failure
Correct sizing is essential to restore your TV to its original picture quality.
TV Screen Size Strips are manufactured to fit specific TV diagonals such as 32-inch, 43-inch, 55-inch, or 65-inch models. A 55-inch strip set will not fit a 43-inch TV even from the same brand.
Number of Strips per TV Some TVs use as few as 2–4 long strips (edge-lit designs), while others use 10–16 shorter strips (direct/full array). Always check how many strips your TV requires.
Length and Layout Strip length must align with mounting points. Edge-lit TVs use longer strips at the edges, while direct LED TVs use shorter strips spread evenly behind the panel.
LED Count and Pitch Strips vary in the number of LEDs (for example, 6–12 per strip) and spacing between them. This ensures even distribution of light across the screen.
Connector Type Different TVs use different connectors for power and control. Even if the length fits, mismatched connectors will prevent installation.
Check the Model Number: Look at the label on the back of your TV. Most suppliers list compatible strip sizes based on model numbers.
Measure Old Strips: If you disassemble the panel, you can directly measure the length and LED count of existing strips.
Cross-Reference with Manufacturer Data: Many professional suppliers provide compatibility charts that match strip models with TV brands and screen sizes.
Ask a Specialist: If uncertain, consult a repair technician or supplier to avoid buying the wrong part.
While every TV model is different, some common sizes include:
32-inch TVs: Typically 2–4 long strips or 6–8 shorter ones
43-inch TVs: 6–10 strips, medium length
55-inch TVs: 10–12 strips in direct LED designs
65-inch TVs: 12–16 strips for full coverage
75-inch TVs: Large arrays of strips, requiring careful matching
Size is only one factor. Quality matters equally. Look for:
High brightness LEDs with consistent color temperature
Proper heat dissipation to extend lifespan
ISO and RoHS compliance
Tested reliability for long-term stability
