tv backlight strip models are usually classified by screen size, lighting structure, LED quantity, voltage, strip length, and panel matching code. For repair companies, spare parts wholesalers, and service teams, understanding common models helps reduce wrong orders and improve stock planning. A tv backlight strip may look simple, but one small difference in connector direction, LED spacing, screw hole position, or voltage can affect installation and screen brightness.
StarSharp’s public product information shows more than 5,000 backlight strip specifications, 10 automated production lines, and daily output up to 100,000 strips. This model range is important because TV repair demand is fragmented across many screen sizes and panel structures.
Most backlight models can be grouped by TV size first, then confirmed by detailed part information. Common size categories include 26 inch, 32 inch, 39 inch, 43 inch, 50 inch, 55 inch, 65 inch, and 75 inch. However, size is only the first filter. The final match should also include strip code, LED count, voltage, connector layout, and physical length.
| Model Category | Common Screen Range | Key Matching Details |
|---|---|---|
| Small-size strips | 26 to 32 inch | Shorter length, lower LED count, simple frame layout |
| Mid-size strips | 39 to 43 inch | More model variations, connector direction matters |
| Popular repair strips | 50 to 55 inch | Multiple strips per set, strict lens spacing |
| Large-size strips | 65 inch | Higher brightness demand, stronger heat control |
| Oversized strips | 75 inch and above | Long strip protection, accurate packaging |
| Universal strips | Multiple sizes | Cutting position, polarity, and voltage must be checked |
The 32-inch category is common in repair stock because many compact TVs and small displays use this size. These models may use direct-lit structures with several strips installed behind the panel. StarSharp’s 32-inch product information includes examples using 7 plus 8 LED chip layouts, aluminum substrates, and 3V voltage design, which shows why LED arrangement and voltage must be confirmed before ordering.
For inventory planning, 32-inch strips are often suitable for regular stock, but buyers should still separate them by panel code and strip number. Two 32-inch TVs may use different LED quantities or connector positions.
The 43-inch category has strong repair demand because it is widely used in home TVs, hotel displays, and commercial screens. StarSharp’s 43-inch category lists 48 products, showing that one screen size can include many different strip structures.
When selecting 43-inch models, buyers should pay attention to strip length, LED spacing, voltage, and lens height. If the lens position does not match the diffuser distance, the repaired screen may show uneven brightness or white spots.
55-inch strips are among the most common tv backlight strip models list items for repair channels. This size often uses multiple strips in one complete set, so consistency across each strip is important. StarSharp’s 55-inch product information includes models with 4 LED beads per strip and 9 strips per set, using 6V voltage design in one listed example.
For batch purchasing, the full set should be checked rather than a single strip only. LED brightness, connector direction, strip code, and hole position should remain consistent across the set.
Large-size TVs usually require longer strips, more stable heat dissipation, and better packaging protection. StarSharp’s 65-inch category lists 52 products, which reflects the wide model coverage needed for large-screen repair.
For 65-inch and larger models, buyers should check whether the product is direct-lit or edge-lit. Direct-lit models usually depend on strip quantity and rear-frame layout. Edge-lit models depend more on side position, light guide matching, and strip straightness.
Universal strips are useful for repair teams that need flexible stock. StarSharp’s led tv backlight category includes universal models such as 7 LED 3V 700 x 18 mm and 6 LED 3V or 6V 1W 590 x 17 mm. These examples show that universal models still have clear technical limits, including length, width, voltage, and LED count.
Universal strips should be used carefully. Cutting position, polarity, adhesive method, and installation distance must be checked before repair. They can reduce emergency stock pressure, but exact-match models are still better for repeat repairs.
As a wholesale supplier, we recommend preparing a model file for every repeated order. The file should include original strip photos, TV size, panel code, strip code, LED quantity, voltage, connector style, length, and width. This makes reorder communication faster and reduces mismatch risk.
For customers managing many repair models, StarSharp can support direct-lit strips, side-entry strips, commercial display backlight products, and universal models. Clear labeling and separated packing also help warehouses identify models quickly after delivery.
Common TV backlight strip models are not defined by screen size alone. A reliable model list should combine size category, lighting structure, voltage, LED count, strip length, lens spacing, and connector layout.
For stable purchasing, the best method is to build a practical model database from real repair demand. Fast-moving sizes can be stocked regularly, rare versions can be ordered after confirmation, and universal strips can support urgent repairs when exact models are not immediately available.
