Laptop Monitors: LCD, LED & OLED

Today’s lesson will compare and contrast the laptop monitors and examine their variations.  We begin with screen displays.

The most common top of screen display is LCD, liquid crystal display which is an active matrix and a thin filled transistor or TFT) which work I harmony.  The crystals arrange themselves in a specific way and the TFT helps to keep them displayed.

They also work in conjunction with a backlight so the crystals can actually be seen, and an inverter converts DC power to AC power, are measured in Aspect Ratios and resolutions.

You’ll learn what’s meant by aspect ratio, what a pixel is, how resolution works, and you’ll learn how to distinguish glossy finish versus a matte, which provides less glare.

LED monitors are light emitting diode monitor are brighter, clearer displays with much better contrast backlighting but also more costly.

OLED monitors are Organic LED’s is composed of organic materials that support a display not heavily reliant on electricity as with it the LCD or LED.

Plasma screens are actually plasma gas which is used to create images and display.  You’ll learn about the term “burn in” and what happens to cause this event and why it’s not as a laptop monitor but rather for TV viewing.
