Edge-lit liquid-crystal displays (LCDs) are one of the most common types of displays on the market. Like all LCDs, they feature liquid pixels. Edge-lit LCDs, however, feature a specific type of backlighting that’s not found elsewhere. They leverage a series of light-emitting diodes (LEDs) to illuminate their pixels. The LEDs are placed along the perimeter of the display, which is why they are known as “edge-lit LCDs.”
Energy Efficient
You can rest assured knowing that edge-lit LCDs are energy efficient. All LCDs are energy efficient, but edge-lit LCDs are particularly energy efficient thanks to their backlighting technology. They only feature LEDs along the perimeter. In comparison, other LCDs , such as those that use full-array backlighting technology, feature rows and columns of LEDs directly behind the pixel layer. With fewer LEDs, edge-lit LCDs are typically more energy efficient.
Available With Local Dimming
There are edge-lit LCDs available with local dimming. Local dimming is a feature that uses dimming zones to improve contrast. With local dimming, the screen is divided into multiple zones. Edge-lit LCDs can automatically adjust the brightness of these dimming zones independently of each other.
Low Profile
Edge-lit LCDs offer a low-profile design. They are thinner, in fact, than most other types of LCDs. This is because edge-lit LCDs only require LEDs along the perimeter. Other types of LCDs require LEDs directly behind the pixel layer. By placing the LEDs along the edges, edge-lit LCDs are thinner than their counterparts.
Costs Less
Another benefit of edge-lit LCDs is the cost. While prices vary, most edge-lit LCDs cost less than other types of LCDs, specifically full-array LCDs. Backlighting technologies affect production costs. Edge-lit is a relatively simple backlighting technology that’s easy to implement. And because manufacturers can implement it at a low cost, edge-lit backlighting offers cost-savings benefits to customers who purchase these LCDs.
Uniform Brightness
Edge-lit LCDs offer uniform brightness. With full-array backlighting, there’s a chance that some of the LEDs may produce significantly more light than others, which can lead to light pooling. Edge-lit LCDs don’t suffer from light pooling. They only have LEDs along the perimeter, so they produce uniform brightness.
In Conclusion
There are benefits associated with all types of LCDs — and edge-lit LCDs are no exception. They are energy efficient, available with local dimming, offer al ow-profile design, cost less than many other types of LCDs, and they produce uniform brightness.
