Liquid-crystal displays (LCDs) are often categorized according to their backlighting technology. You may come across cold cathode fluorescent lamps (CCFL), for instance. CCFL-backlit LCDs have become increasingly popular. They receive their namesake from their backlighting technology. All CCFL-backlit LCDs feature CCFL backlighting.
What Are CCFL-Backlit LCDs?
CCFL-backlit LCDs are LCD devices that feature CCFL backlighting. They still have a pixel layer. CCFL-backlit LCDs simply use CCFL technology to illuminate their pixel layer.
All LCDs have a pixel layer consisting of liquid, organic pixels. While other types of displays feature self-illuminating pixels, LCDs do not. Instead, they feature a separating backlighting layer. CCFL-backlit LCDs use CCFL technology for their backlighting. CCFL involves the use of fluorescent lamps that contain mercury vapor. When ionized, the fluorescent lamps will illuminate, thereby producing light that shines through the pixel layer.
Advantages of CCFL-Backlit LCDs
CCFL-backlit LCDs offer several advantages. They offer a high level of brightness, for instance. If you’re looking for a new display that’s capable of producing bright images, you may want to choose a CCFL-backlit LCD. They are often preferred over other types of displays because of their high level of brightness.
You can rest assured knowing that CCFL-backlit LCDs are long-lasting. CCFL backlighting has been around for decades. During this time, it’s been used in countless display devices. As a result, CCFL-backlit LCDs are reliable. You don’t have to worry about them failing prematurely. CCFL-backlit LCDs will weather the hands of time — all while producing bright, high-quality images.
CCFL-backlit LCDs often feature a diffuser. Diffusers are sheets of acrylic plastic that are designed to diffuse light. They diffuse the light of the CCFL bulbs so that it spreads evenly across the pixel layer.
Disadvantages of CCFL-Backlit LCDs
When compared to other backlighting technologies, specifically light-emitting diode (LED), CCFL consumes more energy. All backlighting technologies consume energy. LED, though, is more energy efficient than CCFL. LED-backlit LCDs will consume less energy than CCFL-backlit LCDs, resulting in a lower cost of operation.
You may notice that CCFL-backlit LCDs are thicker than LED-backlit LCDs. They typically require an inverter to convert the direct current (DC) voltage. Inverters are usually built into LCDs. Because they are part of LCDs, inverters make them thicker.
For a thin and low-profile design, you may want to stick with an LED-backlit LCD. LED-backlit LCDs don’t require an inverter, whereas CCFL-backlit LCDs do require an inverter.
