At present, many manufacturers have changed a concept when promoting their products. It is clearly LED backlight display, but it is called LED display for short. In fact, LED display and current LED backlight display have essential differences. So what are the differences and connections between LED and LED backlight? In this paper, we will introduce the basic concepts of these two technologies.

What is the difference between LED display and LED backlight display?

so what are the differences and connections between LED.
LED backlight? Hefei LED display editor will introduce the basic concepts of these two technologies to you in this article.
in this article, we will introduce the basic concepts of these two technologies  What is led display?  LED display refers to the display that directly uses LED (light emitting diode) as the pixel light-emitting element.
the light-emitting diodes that constitute the array directly emit red, green and blue light, thus forming a color picture.
however, due to the large diameter of the light-emitting diodes themselves,
the distance between pixels of the same color is also large (that is, we often call the point distance), Therefore, LED display screen is usually only suitable for large screen display.
in general, LED display screen is suitable for large screen display  Full color LED display integrates microelectronic technology, computer technology and information processing.
with the advantages of bright color, wide dynamic range, high brightness, long life, stable and reliable operation, it has become the most advantageous public display media. At present, LED display has been widely used in large squares, commercial advertisements, stadiums, information dissemination, news release, securities trading, etc, It can meet the needs of different environments.
the  What is LED backlight display?  The LED backlight display is just the backlight source of the LCD, which transits from the traditional CCFL cold light tube (similar to fluorescent lamp) to the LED (light emitting diode).
let's review the basic principle of the LCD  The principle of liquid crystal imaging can be simply understood as.
the principle of liquid crystal imaging is as followsWhen the external voltage is applied to deflect the liquid crystal molecules, the light from the backlight is blocked like a gate, and then the light is projected into the color filters of different colors to form an image.
the results show that the liquid crystal molecules can be deflected by the external voltage, and the light from the backlight is blocked like a gate  The transition of backlight module from CCFL to LED can bring many benefits.
it can make the brightness of the display screen more uniform, the power consumption of the product is lower, and the appearance can be thinner and more fashionable.
however, w-led backlight is commonly used in the market at present.
in fact, this kind of backlight only replaces the luminous components, However, the improvement of the display effect is very weak or not.
rgb-led (three color LED), which can significantly improve the display effect of liquid crystal products, can obviously improve the display effect.
but at the same time, the production cost is high, so it is used in high-cost liquid crystal TVs.
however, rgb-led is widely used in high-cost liquid crystal TVs  At present, LED display refers to the display products with white LED backlight.
the difference between LED display and ordinary LCD display is the change of backlight.
LED display is the change of backlight  Generally speaking, led and LED backlight are totally different imaging technologies.
however, the LED backlight display or LCD TV commonly seen in the market is actually not a replacement of the display technology.
it can only be said that it is a replacement of the original.
at the same time, it is not correct to confuse LED backlight with LED.
