Everyone understands the misunderstanding of LCD and LED splicing screen

With the popularization and application of LCD splicing display, many customers are misled by advertisements to some extent. They often see advertisements that say LED splicing screens and LCD splicing screens. In fact, LED splicing screens do not refer to new products, nor LCDs have changed. The so-called LED LCD splicing screen full name should be LED-backlit LCD display, while the LCD panel is still LCD display, not LED, for LCD, the most important is the LCD panel and backlight type, most of the LCD on the market The panels are all TFT panels, and the ultra-narrow splicing screens are the same. The difference between LEDs and LCDs is mainly due to their different backlight types, while LED backlights and CCFL backlights are diodes and cold cathode lamps.

LCD is the acronym for Liquid Crystal Display, which means liquid crystal display, which is the liquid crystal display that we often say now, and LED display is only one kind of liquid crystal display, that is, liquid crystal display with LED as backlight, LCD splicing screen That is, including the LED, and the LED display actually refers to the display whose backlight is CCFL. The so-called LED splicing screen refers to a liquid crystal splicing screen with a backlight type of LED, and the panel is actually an LCD splicing screen.

CCFL refers to a liquid crystal display using CCFL (Cold Cathode Fluorescent Lamp) as a backlight source, and LED refers to a liquid crystal display using (Light Emitting Diode) as a backlight source. What is the difference between CCFL and LED? Firstly, in the LCD splicing screen market, the LCD splicing screen with CCFL as the backlight is used, but due to its high power consumption and shortcomings, LED has become the mainstream of the splicing screen market in recent years, basically replacing the CCFL because LED has the characteristics of small size, low power consumption, energy saving and environmental protection. It achieves high brightness while taking care of both thin and light, so it is justifiable to choose LED as backlight.
