The old and bulky cathode ray tubes have had their day but display technology has moved on considerably. The replacement of old CRT technologies came in many forms but the one to catch on was liquid crystal display. By placing liquid crystals in between two thin transparent films and then passing electrical current through it, the crystals can be arranged in the shape and form of desired picture.

However, the limitation with these liquid crystals is that they are rather dark so in order to see the picture, they need to be lit from the back or from sides. Earlier LCD lighting was done by fluorescent or other technologies but these days, LED light circuit board has become the primary way to do LCD backlighting. There are many reasons why the LED tech has become dominant for displays in the market.

Better Picture Quality in Display Screens: 

The old CCFL fluorescent light backlit screens were energy hungry monsters and they were nowhere near as bright or as reliable as modern LEDs. LEDs are capable of producing brighter and more vibrant displays compared to CCFLs. LED backlit Liquid Crystal Display screens offer higher peak brightness levels, resulting in better visibility in well-lit environments and improved outdoor readability. Additionally, LEDs can provide a wider color gamut and more precise color reproduction, delivering sharper and more accurate images.

LED backlit LCDs excel in producing high contrast ratios, which is essential for displaying deep blacks and vivid whites. This enhances the viewing experience as it provides richer and more immersive visuals, making movies and gaming more enjoyable. Further to this, LED light circuit boards are solid-state components. They are more durable and shock-resistant than CCFLs, which contain fragile glass tubes. This durability leads to a longer lifespan for LED backlit LCDs, reducing the frequency of replacements and minimizing maintenance costs.

Making Displays Energy Efficient and More Eco-Friendly

Compared to the older CCFLs which were energy hogs, the degree of energy efficiency that can be obtained from LEDs is many magnitudes of order higher. LEDs consume up to 30-40% less power which means it can be run for longer hours at the same amount of electricity being used. This lower power consumption not only reduces electricity bills but also contributes to a smaller carbon footprint, making LED backlit LCDs a greener choice.

Unlike CCFLs, which contain small amounts of toxic mercury, LED Light Circuit Boards are mercury-free. Mercury is a exceptionally harmful for people and environment at the same time. This makes LED backlit LCDs more environmentally friendly and safer for disposal at the end of their life cycle. Compared to plasma displays, which can generate significant heat, LED backlit LCDs produce minimal heat during operation. This heat reduction contributes to a more comfortable operating environment and extends the lifespan of the display.

Variations in Display Size and Form Factors

 LEDs are compact and can be used to create thinner and lighter displays. LED backlit Liquid Crystal Display screens are slimmer and more lightweight than traditional CCFL-backlit LCDs, making them suitable for sleek and modern designs in devices like ultra books, tablets, and flat-panel TVs. Further there is also the fact that LED backlit LCDs can be easily dimmed and dynamically adjusted to match ambient lighting conditions. This not only saves energy but also enhances user comfort and visibility in changing lighting environments.

Another key factor is the movement to flexible displays. By their very nature, the old style CCFLs were inherently rigid. You cannot even curve them, forget about the kind of bending over itself that folding mobile phones have been able to achieve. LED backlit screens are here to stay for a long time since there is still a lot of scope of innovation with regard to the tech behind it.
