Comparative analysis of LED display and LCD display

The LED display is a display screen for displaying various information such as text, graphics, images, animations, quotes, videos, and video signals by controlling the display mode of the semiconductor light-emitting diodes.

A liquid crystal display, or LCD, is a flat, ultra-thin display device that consists of a number of colored or black-and-white pixels placed in front of a light source or reflective surface. LCD monitors are low power consumption and are therefore favored by engineers for use in battery-operated electronic devices. Its main principle is to stimulate the liquid crystal molecules to generate dots, lines and faces to match the back lamp.

Compared with LCD displays, LED displays have advantages in terms of brightness, power consumption, viewing angle and refresh rate. The navigation of the web page has been canceled. LED technology can be used to make displays that are thinner, brighter, and sharper than LCDs.

So, what is the difference between LED display and LCD display? KONWHAI LCD advertising machine manufacturers Xiaobian for your analysis and answer.

KONWHAI-Wall advertising machine

Comparative analysis of LED display and LCD display:

1. The power consumption ratio of LED to LCD is about 1:10, and LED is more energy efficient.

2. LED has a higher refresh rate and better performance in video.

3. LED provides a viewing angle of up to 160 °, can display a variety of text, digital, color images and animation information, can play TV, video, VCD, DVD and other color video signals.

4. The single element of the LED display has a reaction speed of 1000 times that of the LCD screen. It can also be taken under strong light and is suitable for low temperatures of minus 40 degrees.

LED display integrates microelectronic technology, computer technology and information processing, with its bright color, wide dynamic range, high brightness, high definition, low working voltage, low power consumption, long life, impact resistance, colorful and stable operation. Reliable and other advantages, become the most advantageous next-generation display media, LED display has been widely used in large squares, commercials, stadiums, information dissemination, news release, securities trading, etc., to meet the needs of different environments.

Simply put, LCDs and LEDs are two different display technologies. LCDs are displays made up of liquid crystals, while LEDs are displays made up of light-emitting diodes.

The difference between LED display and LCD display:

1. LED backlight: power saving (30%~50% compared with CCFL), high price, high brightness and high saturation.

2. CCFL backlight: Compared with LED backlight power consumption (still much more than CRT power saving), cheap.

3. Screen difference: LED backlight color is more vivid, and the saturation is high (CCFL and LED natural light source are not the same).

4. How to distinguish: LED backlight will be especially emphasized as LED TV, CCFL LCD TV is not emphasized.
