The seven segment display is a used in place of the more complex dot matrix displays. It is called so because it consists of seven segments of light emitting diodes (LEDs) that are assembled like decimal 8 as shown in the following figure. Seven segments LED display can be used in applications where an electronic display device is required for Responses Rates. A CRT monitor has a fast response rate whereas the response rate for LCDs is very slow. LEDs have the best response in comparison to the other two. Response rates are a big deal to gamers mostly. These are some of the key differences between LEDs, LCDs and CRTs monitors. Here’s how an LCD (liquid crystal display) TV works: Unlike OLED TVs, described down below, LCD TVs require a backlight, which shines through a filter to produce colors. But the best LCD/LED LED TVs and monitors use less power, can be lighter and thinner, and can have a better image quality than CCFL LCD TVs and monitors. However, while WLED backlights covering the standard 100% sRGB color space are most common, there are a few different LED backlights available targeting wider color gamut coverage, such as: Nowadays, almost all
Emissive displays, which don’t need a backlight at all, tend to be thinner. LCD Panasonic TC-65AX800U LCD TV Image used with permission by copyright holder. The plasma TV was the flat-panel
1. Due to the simplicity of production and the single light source used in LCDs, they are more affordable than AMOLED ones. Most low-cost cell phones also have LCD screens. 2. LCD screens offer vivid whites, and the backlight produces a lot of light through the pixels, making it simple to read outside.

Both LED and LCD panel technologies use Liquid Crystal Display (LCD). They also have lamps at the back of the display that helps produce the images you see on your screen. The main difference between LCD and LED technologies is in the lights you find at the back of the screen.
