What is the difference between an LED Display Screen and an LCD Display Screen?
What is the LED? What is the difference between an LED Display Screen and an LCD Display Screen? Here we understand the next.
At present, China in the LED base material manufacturing and the international there is still a certain gap, but the LED Display Screen, the Chinese design and production technology level and international synchronization. The LED Display Screen is a Display Screen device consisting of light emitting diodes. It uses low-voltage scanning drive, with: less power consumption, long life, low cost, high brightness, less failure, large viewing angle, visual distance and so on.
What is LCD?
LCD Display Screen of the original is Liquid Crystal Display Screen, take the first letter of each word, the Chinese more known as "LCD flat panel Display Screen" or "liquid crystal Display Screen." Its working principle is the use of the physical characteristics of liquid crystal: when the arrangement becomes orderly, so that light easily through; no power when the arrangement of chaos, to prevent the passage of light, that simple point is to let the LCD as a gate-like barrier or let the light penetrate.
LCD benefits are: compared with the CRT Display Screen, LCD's main advantages include zero radiation, low power consumption, small heat dissipation, small size, accurate image reproduction, character Display Screen sharp and so on.
LED and LCD comparison
LED Display Screen and LCD Display Screen compared to LED in the brightness, power consumption, viewing angle and refresh rate, etc., are more advantages. LED and LCD power consumption ratio of about 10: 1, and a higher refresh rate makes the LED in the video has better performance, can provide a wide angle of 160 °, you can Display Screen a variety of text, digital, color images And animation information, you can also play TV, video, VCD, DVD and other color video signals, multiple Display Screens can also be broadcast network. Organic LED Display Screen a single element of the reaction speed is 1000 times the LCD screen, in the light can also take care of the wrong, and to adapt to minus 40 degrees low temperature. The use of LED technology, can produce thinner than LCD, brighter, more clear Display Screen, has a wide range of applications.
Simply put, LCD and LED are two different Display Screen technology, LCD is composed of liquid crystal Display Screen, and LED is composed of light-emitting diode Display Screen. LED Display Screen and LCD Display Screen compared to LED in the brightness, power consumption, viewing angle and refresh rate, etc., are more advantages.
