What is an OLED Display
OLED panels are made of organic materials. This is a demonstration technique that when applied through electricity emit their own light.
How does OLED display work
Organic Light-Emitting Diodes is a flat light emitting technique and is made up of individual image elements. Which is made by placing a series of organic thin films between anode and cathode. When an electric current is applied between the Cathode (which injects electrons) and Anode (which removes electrons) of each pixel.
OLEDs are displays that do not require a backlight and are therefore thinner and more efficient than LCDs.
1. White Light is a combination of multiple wavelength.
2. Traditional LEDs can't emitted true white Light. Other means are used to produce or simulate white.
3. For White OLEDs multiple emissive layers combine to emit the wavelength needed for White light.
4. The Wavelength emitted by each layer is determined by material used and is controlled on the molecular level.
5. OLEDs are a uniform planar. Colour rendering is excellent, capturing colours not measured by the traditional colour rendering index. Naturally diffuse light no hotspots or high glare typically caused by optics or waveguides with traditional LEDs.
Is OLED display good for eyes
Technology has become quite advanced since earlier times, one of them is OLED technology. Now the question is whether the OLED display is good for our eye or not.
See, there are advantages and disadvantages to every display, whether it is an OLED display or an AMOLED display and an IPS LCD. The biggest reason is the blue light emanating from the phone and the flicker on the phone, which damages our eyes, causing headaches and troubles.

Protect your eyes while using a mobile phone. Blink frequently/splash your eyes with water. For this, you should use the 20-20-20 rule. Every 20 minutes, take a 20-second break and focus your eyes at least 20 feet away.
Advantages or Pros OLED display
1. They are lighter, cheaper, thinner, and more flexible.
2. Produces its own light.
3. Nicer colors and better image quality.
4. Higher brightness.
5. Do not suffer screen lag or blur.
Disadvantages or Cons OLED display
1. High cost of production.
2. Burning screen problem.
3. Limited lifetime of organic materials.
4. The OLED screen consumes a lot of power.
5. OLED displays are very sensitive to water.
What is the difference between OLED and AMOLED display?
The biggest difference between the OLED display and AMOLED display is color. In Amoled, you will get to see colors much better than the OLED display and the OLED display gives you to see the pure black color compared to the AMOLED display.

Today's most demanding Active Matrix Organic Light Emitting Diode (AMOLED) display is that. Amoled has an additional layer of TFT to control the flow of current in each pixel.
At the same time, we see the OLED display, it is flexible, thinner, and lightweight. These displays consume less power.
