Display Screen LCD with TFT, INCELL, OLED, Hard OLED, Soft OLED, AMOLED, technology, what is the difference?

It often happens that you need to buy a screen and find yourself facing a variety of qualities and different technologies. For greater clarity, below is a brief description of the differences:

1) TFT "Thin Film Transistor Liquid Crystal Display",
These displays are made with thin layers of active semiconductors and are backlit by an LED panel. They have a refresh rate of up to 240Hz, resulting in fast response times. However, their contrast is lower than others, but they are continually improving.

2) INCELL "In-Cell Display",
These displays are similar to TFT displays, structured with the placement of the touch screen directly on the LCD panel, making the touch screen channel grid invisible.

3) IPS "In-Plane Switching Display",
This is an LCD display developed by Hitachi to improve viewing angles and color reproduction compared to TN panels. They are slower than TN displays but compatible with more recent color standards like DCI-P3 and Rec. 2020.

4) Hard OLED "Organic Light Emitting Diode",
These are rigid displays composed of very thin panels. The illumination and colors are emitted directly by LEDs, and the quantity of LEDs determines pixel density.

5) Soft OLED "Organic Light Emitting Diode",
These are flexible displays and, in some cases, foldable, composed of very thin panels. The illumination and colors are emitted directly by LEDs, and the quantity of LEDs determines pixel density.

6) Amoled "Active Matrix Organic Light Emitting Diode",
These are active matrix OLED displays made by Samsung to improve the quality of OLED displays. They offer greater energy efficiency and image quality.
