LED backlight strips are essential components inside modern LCD televisions. They provide the uniform brightness that makes colors vivid and images sharp. When it comes to repairs or replacements, one of the most common questions is: how many LED strips are in a tv backlight? The answer depends on the TV’s size, design, and backlight configuration.
In this setup, LED strips are placed across the entire back of the panel.
The number of strips is usually higher because they cover the whole screen area.
For example, a 55-inch TV may use 10–12 strips, while a 65-inch model might require 12–16 strips.
Here, LED strips are positioned only along the edges of the screen (top, bottom, or sides).
The light is spread across the panel by a light guide plate.
Edge-lit designs typically use 2–6 longer strips, depending on the screen size.
While every brand and model differs, these are common ranges:
32-inch TVs: 2–6 strips (edge-lit) or 6–8 strips (direct LED)
43-inch TVs: 6–10 strips
55-inch TVs: 10–12 strips
65-inch TVs: 12–16 strips
75-inch TVs and larger: 16 or more strips
Smaller models tend to use fewer strips, while larger TVs need more to maintain uniform brightness.
Backlight Technology – Direct LED requires more strips than edge-lit.
Panel Size – Larger screens need additional strips for even illumination.
Brightness Level – High-brightness TVs may use more strips or LEDs per strip.
Design & Cost – Some manufacturers optimize strip count to balance quality and production costs.
Repair and Replacement: Knowing how many strips your TV uses helps you order the correct quantity for a full replacement.
Brightness Uniformity: More strips usually mean smoother light distribution and fewer visible hotspots.
Energy Efficiency: Fewer, higher-power LEDs can consume more energy than more evenly distributed strips.
Check the Service Manual: Many TV brands list the backlight configuration in technical documentation.
Disassemble Carefully: If you remove the panel, you can count the strips directly.
Supplier Compatibility Lists: Professional suppliers match strip sets with specific TV models.
Model Number Lookup: Using your TV’s model number is the safest way to find the exact strip count.
For accurate strip replacement, sourcing from a reliable supplier is key. StarSharp offers more than 5,000 models of led backlight strips for TVs ranging from 24 inches to over 80 inches.

The number of LED strips in a TV backlight depends on the screen size, layout, and design type. Smaller edge-lit TVs may use as few as 2 strips, while large direct LED models can require 16 or more. To find the exact count, always check your TV’s model number or consult a trusted supplier like StarSharp. Choosing the right strip set ensures reliable repairs and restores the screen to its original performance.
