Laptops and Mobile Devices Lesson 002: Display Types Part 2

What does TN Panels stand for?

Twisted Nematic Panels.

What does IPS Panels stand for?

In-Plane Switching Panels.

What does VA Panels stand for?

Vertical Alignment Panels.

What are the three types of LCD and LED panels?

TN, IPS, and VA.

Twisted Nematic Panels

Work by twisting liquid crystals to control the passage of light through the display.

What is the oldest and most basic type of LCD or LED display?

TN displays.

What are TN displays notably good for?

High motion applications like gaming due to faster response times.

What are the caveat/s to using a TN display?

They suffer from poor color accuracy and limited viewing angles.

Where are TN displays most commonly found?

In budget laptops and entry-level devices.

In-Plane Switching Panels

Rotate liquid crystals horizontally to enhance color accuracy and improve LCD and LED display’s viewing angles.

What is the maximum clear viewing angle of a screen that has In-Plane Switching panels?

Any angle, even up to 178 degrees.

What is the preferred type of LCD or LED display panel?

IPS display.

What is the preferred type of display panel in smartphones, tablets, and modern laptops?

IPS display panels.

What do IPS LCD/LED display panels provide an excellent balance of?

Color reproduction, viewing angles, and response times.

Vertical Alignment Panels

Offer the best contrast ratios by tilting the liquid crystals to block or allow the light to go through.

What does the functionality of VA panels provide?

Deeper blacks and brighter whites compared to TN or IPS panels.

What is/are the caveat/s to using VA LCD/LED display panels?

Slower response times than TN panels and narrower viewing angles than IPS panels.

What use case/s is/are VA LCD/LED display panels good for?

In scenarios where higher levels of contrast is considered more critical than speed or viewing angle flexibility.

Organic Light Emitting Diode Display

Do not require a backlight becase each pixel within can emit its own light.

What does the functionality of OLED displays allow?

Superior contrast ratios.

What makes OLED displays better than LCD and LED displays?

They have higher contrast, are thinner, lighter, and more power efficient.

What is a benefit of the use of OLED displays that have nothing to do with display quality?

The ability to use flexible materials that enable more innovative designs.

What is/are the main drawback/s of using OLED displays?

They aren’t as bright as LCD displays and are susceptible to burn in.

What is burn in?

A phenomenon that can leave a permanent ghost-like image impression in an OLED display.

Mini-LED Displays

Combines the best of LCD and LED backlighting into a newer type of display panel.

What do Mini-LEDs use for displays?

Thousands of tiny LEDs to create highly localized backlighting zones.

What benefit/s does the functionality of Mini-LED displays provide?

Improved contrast and brightness when compared to traditional LCD and LED panels.

Why are Mini-LED displays considered the primary choice for modern premium level laptops and tablets?

They balance the affordability of LCD displays with the high quality visuals of OLED displays.
