In the field of LED display industry, the rapid development and wide application of LED has gradually replaced the development trend of LCD, and LED display has become the dominant in the field of display industry. What are the differences between LCD splicing screen and LED display? Which is better? Mini photoelectric editor here to do a more comprehensive explanation of the difference between LCD splicing screen and led in the end? What are the characteristics and main applications of LCD splicing screen and LED display? Is there such a big difference between LCD and led?
LCD
1、 What is LCD? What is LCD splicing screen?
Liquid crystal display is short for LCD, which mainly includes TFT, ufb, TFD, STN and other types of LCD. It is unable to locate the program input point on the dynamic link library.
LCD splicing screen is the way of LCD display unit splicing, but now the LCD splicing screen light source uses LED backlight, through the splicing control software system, to realize the large screen splicing display effect of a LCD splicing screen body, so there are now LCD splicing screen and led splicing screen. At present, the common LCD splicing screen is LED backlight, such as: 3.5mm55 inch ultra narrow edge LCD splicing screen, 3.5mm46 inch ultra narrow edge LCD splicing screen, 4.9mm47 inch LCD splicing screen, 3.8mm49 inch LCD splicing screen and 42 inch narrow edge LCD splicing screen large screen display system.
2、 What is led? What is led display?
LED is the abbreviation of light emitting diode. LED applications can be divided into two categories: one is led display; Second, LED single tube applications, including backlight LED, infrared LED and so on. Now, as far as LED display is concerned, China’s design and production technology level basically keeps pace with the international level. LED display screen is a display device composed of LED array, 5000 yuan computer configuration list. It adopts low voltage scanning drive, and has the following characteristics: low power consumption, long service life, low cost, high brightness, few faults, large viewing angle, long visual distance and so on.
3、 LCD splicing screen features:
1. High brightness
Compared with TV and PC LCD, LCD splicing screen has higher brightness. The brightness of TV or PC LCD screen is generally only 250 ~ 300 CD / m2, while the brightness of LCD splicing screen can reach more than 500 ~ 700 CD / m2.
2. High contrast
LCD splicing screen has 4500:1, even up to 10000:1 contrast, more than twice as high as the traditional PC or TV LCD screen, and three times as high as the general rear projection.
