What is the difference between LED digital tube and LCD display?
Obviously, the digital tube is an element, and the display is a device. One is the part, the other is the equipment
Digital tube in the MCU, generally only digital display, of course there is a special part of digital tube display, can display date; LCD can realize digital tube can not be achieved, the Chinese characters, special symbols, as long as we write LCD to the corresponding ASC2 code, you can let LCD display the corresponding information.
The difference between LED display and LCD display: LED backlight: save electricity (relative to CCFL, save 30%~50%), high cost, high brightness and saturation. CCFL backlight: power consumption relative to LED backlight (still much cheaper than CRT), cheaper.
Compared with the LCD display, LED display has more advantages in brightness, power consumption, visual angle and refresh rate, etc., and the navigation of the LED page has been cancelled. By using LED technology, a thinner, brighter and clearer display than LCD can be produced.
