"When were LED displays invented?" Let me start by recalling the previous conversation. They wanted to know what LED displays are, and I explained their structure, types, features, and applications. Now they're asking about the invention timeline.

First, I need to ensure accuracy. I remember that LEDs themselves were invented in the 60s, but LED displays came later. Let me verify the key milestones. Nick Holonyak is known for creating the first visible LED in 1962. That's a starting point.

Okay, so I need to explain what LED displays are. Let me start by recalling what I know. LED stands for Light Emitting Diode. I think LED displays are screens that use these diodes to produce images. But how exactly do they work?

First, I remember that LEDs are those small lights used in electronics. They are energy-efficient and have a long lifespan. So an LED display would be made up of many tiny LEDs. Maybe arranged in a grid? Each LED acts as a pixel? Or maybe clusters of LEDs make up a pixel.

We recalling what I know. LED stands for Light Emitting Diode, right? So, LED screens must use these diodes to produce light. But how exactly do they create the images we see?

LED screens are made up of pixels. Each pixel is a tiny dot that emits light. In LED screens, each pixel is made up of LEDs. Wait, but aren't there different colors? So maybe each pixel has red, green, and blue LEDs? Because combining those colors can make any color. Yeah, that makes sense. So by varying the brightness of each of these colored LEDs, you can create different colors.
