Section 1.2 Mobile Device Display Components

What is a key advantage of IPS panels in mobile devices?

Wider viewing angles and better color accuracy

Which LCD subtype offers fast response times but poor color reproduction?

Twisted Nematic (TN)

Which LCD subtype provides deeper blacks and higher contrast than TN but not as good as OLED?

Vertical Alignment (VA)

Which display technology uses backlighting to produce an image?

Liquid Crystal Display (LCD)

Which display type can suffer from image retention or burn-in?

OLED

What is a drawback of OLED displays over time?

Degradation of organic compounds leading to burn-in

What type of display does not require a backlight?

OLED

Which display type is known for true blacks and high contrast ratios?

OLED

What feature of IPS displays makes them ideal for color-sensitive applications?

Accurate color reproduction and consistent color at all angles

Which LCD technology is most energy-efficient?

Twisted Nematic (TN)

Which type of LCD panel is often found in gaming laptops for its fast refresh rate?

TN

What does OLED stand for?

Organic Light-Emitting Diode

How does an OLED screen emit light?

Each pixel emits its own light

What is a benefit of LCD over OLED?

Longer lifespan and no burn-in risk

Which display type generally consumes more power: OLED or LCD?

OLED (especially at high brightness)

Which display type provides the best outdoor visibility?

IPS LCD with high brightness

Which display technology is most prone to motion blur?

IPS LCD (depending on panel response time)

What is the primary difference between OLED and LCD technologies?

OLED emits light per pixel, LCD uses a backlight

Which LCD type is best for wide viewing angles?

In-Plane Switching (IPS)

What LCD subtype offers the deepest blacks among LCD types?

Vertical Alignment (VA)

What is one major disadvantage of TN panels?

Poor color accuracy and narrow viewing angles

Which display type is best for video and multimedia viewing?

OLED

What advantage does OLED have in terms of form factor?

Can be made thinner and flexible

What is ghosting and which panel type is most susceptible?

Image trailing; common in IPS panels with low response time

Which display type can support curved and foldable screens?

OLED

Which panel type offers the lowest manufacturing cost?

TN

What makes OLED ideal for battery-powered devices?

It uses less power when displaying dark content

Which panel type has the slowest pixel response time?

IPS

What is one way to identify an IPS panel?

Consistent brightness and color from side angles

Why might OLED displays not be ideal for static content?

Risk of burn-in with long static images

What is the contrast ratio advantage of OLED displays?

Infinite contrast ratio due to true black pixels

What does VA stand for in LCD technology?

Vertical Alignment

Which display type can achieve the fastest refresh rates?

TN

Why are OLED displays thinner than LCDs?

They don't require a backlight layer

What determines the energy consumption of an OLED display?

The brightness and content displayed (more white = more power)

Which display type shows the best performance under extreme viewing angles?

IPS

What kind of display panel is often used in high-end smartphones?

OLED

Which display type is typically found in budget laptops?

TN

Which display is more resistant to motion blur: OLED or VA?

OLED

What is one way OLED improves battery life in dark mode?

Black pixels are turned off, consuming no power

Which type of LCD panel is most balanced in terms of contrast and viewing angle?

VA

What causes color shifting in TN panels?

Viewing from angles other than directly in front

What is one common symptom of a failing OLED display?

Burn-in or ghost images

Which display type generally provides the fastest pixel response?

TN

What does the 'in-plane' in IPS refer to?

Orientation of the liquid crystals

Why are OLED screens better at displaying HDR content?

Higher contrast and brightness control per pixel

Which display type is typically used in tablets and premium monitors?

IPS

Which panel type combines good color and faster response than IPS?

VA

What makes OLED more vulnerable to screen aging?

Organic materials degrade over time
