The difference between LCD segment code screen and LED display screen
1. What is LCD? LCD is the full name of Liquid Crystal Display. There are mainly TFT, UFB, TFD, STN and other types of Liquid Crystal displays that cannot locate the program input point on the dynamic link library. TFT is commonly used in notebook LCD screens. TFT ( Thin Film Transistor) It refers to the thin film transistor. Each liquid crystal pixel is driven by a thin film transistor integrated behind the pixel, so that the screen information can be displayed with high speed, high brightness and high contrast, it is one of the best LCD color display devices at present and is the mainstream display device on notebook computers and desktop computers. Compared with STN, TFT has excellent color saturation, restoring ability and higher contrast, and it is still very clear in the sun, but the disadvantage is that it consumes more power and has higher cost. Second, what is LED? LED is the abbreviation of Light Emitting Diode. LED applications can be divided into two categories: one is LED display screen; The second is the application of LED single tube, including backlight LED, infrared LED, etc. Now as far as LED display screen is concerned, China's design and production technology level is basically synchronized with the international level. LED display screen is a 5000 yuan computer configuration sheet composed of light emitting diodes. It adopts low voltage scanning drive and has the characteristics of low power consumption, long service life, low cost, high brightness, few faults, large viewing angle, long visual distance, etc. Third, the difference between LCD and LED compared with LCD display, LED has more advantages in brightness, power consumption, visual angle and refresh rate, etc. Navigation to the web page has been canceled. Using LED technology, thinner, brighter and clearer displays can be produced than LCD. In short, LCD and LED are two different display technologies. LCD is a display screen composed of liquid crystals, while LED is a display screen composed of light emitting diodes.
