At present, many manufacturers have stolen a concept when promoting their products. It is clearly an LED- backlit display that is simply referred to as an LED display. In fact, LED displays are essentially different from current LED-backlit displays. Of course, it is easy for readers to confuse the very advanced technology of OLED, then what is the difference and connection between LED, LED backlight, OLED? In this article, I will introduce you to the basic concepts of these three technologies.

What is an LED display?

The LED display refers to a display in which LEDs (light-emitting diodes) are directly used as pixel light-emitting elements, and the light-emitting diodes constituting the array directly emit light of three colors of red, green and blue, thereby forming a color picture. However, since the diameter of the light-emitting diode itself is large, the distance between the pixels of the same color is also large (that is, the dot pitch as we often say), so the LED display is generally only suitable for large-screen display.
