Most people buy TV’s and mobile phones that have LED or LCD screens, but more often than not, they don’t know what the difference is. When deciding which one to buy for yourself, make sure you know the difference between the two.
LCD stands for liquid crystal display. This is the fundamental display technology that is used to make most of the tablets, smartphones, and televisions today. To work, it requires a liquid crystal molecule that is usually induced by electrical fields.
The fields allow it to take certain patterns by blocking light or allowing some light to pass through it. In each pixel displayed, LCD lights have blue, green and red colors.
The color intensities are controlled carefully. This is how you get clearly defined images that have millions of colors.
Types of LCD TVs
- Flat-screen LCDs
These are usually about an inch or two thick. They have a very sleek look and have various standing or being mounted on the wall options on the surface. They are also more expensive.
- Rear projection LCDs
These support situations where the images produced are sent to the front from the rear of the TV. They are usually 60 inches thick and heavy.
- Front projection LCDs
These are normal projectors that share the image to the front of a screen. The TV is usually a box fitted anywhere in a room. The flat-screen where the image is displayed may be as big as 300 inches.
LED Light Panels
Flexible LED Displays, on the other hand, are Light Emitting Diodes. In the past, LCD lights were mostly used. However, manufacturers found out that energy could be saved by using LEDs. They also allow users to turn off individual diodes when the light is not being used.
LED TVs are classified depending on their backlighting methods. The LED TVs are usually sold at a higher price than LCD TVs because most LCDs use CCFLs as their lighting mechanisms. They are also energy efficient and consume less power. They save up to 30% of the total energy used with LCD TVs.
Types of LED TVs
- Edge LEDs
These are the most common LED types on the market. They are usually around the rim of the screen and have a special diffusion panel. The panel is used to spread light behind the screen evenly. This backlighting technology has allowed TVs to be very thin; some are as thin as one inch. This makes them lightweight and portable.
- Full array LEDs
This is where the Flexible LED Displays are arranged behind the screen as a set. These are however, not capable of dimming or lighting independently.
- Dynamic RGB LEDs
While the lights are put in as a set, they allow certain areas to be dimmed without affecting other areas. This one also offers its user more color options.
In conclusion, one of the small hiccups with this LCD displays is that they have no light of their own. However, they can be lit using reflected ambient light.
Nevertheless, all LCD lights must have a backlight that is used to shine the light through the displays.
