What's the difference between LCD and LED panel?

With the popularization and application of LCD video wall, we can often see advertisements saying led video wall and LCD video wall. In fact, led video wall is not a new product.

The full name of the so-called LED LCD video wall should be led backlit LCD, while the LCD control panel is still LCD screen, not led screen. Generally speaking, for LCD, The most important thing is the LCD panel and backlight type. Most of our LCD panels on the market are TFT panels, and the ultra narrow edge video wall is the same. Today, HDFocus will tell you the main differences between LED and LCD.

The main difference between LED and LCD is the choice of backlight system type, while LED backlight and CCFL backlight are two diodes and cold cathode lamp respectively.

LCD is the acronym of liquid crystal display, which means liquid crystal display. Now we often say liquid crystal display. LED display is only one kind of liquid crystal display, that is, LCD with LED as the backlight. LCD video wall includes LED, and LED display actually refers to the display with CCFL as the backlight. The so-called led splicing screen refers to the LCD video wall whose backlight type is led. In fact, the panel is still LCD video wall.

CCFL refers to the LCD TV display with CCFL (cold cathode fluorescent lamp) as the control backlight, while LED refers to the LCD display with (light emitting detection diode) as the backlight. What is the difference between CCFL and led? 

First of all, in the LCD splicing screen market, CCFL is used as the domestic backlight material splicing screen. However, due to its high power consumption analysis, in recent years, LED has become the mainstream of splicing screen market, and the basic technology has replaced CCFL, because LED has the characteristics of small size, low power consumption, energy saving and green environmental protection, In the light of both products at the same time to achieve a higher brightness, so we choose LED as backlight production is also a kind of excusable thing.
