Display Devices

Characteristics of LCD

1. Most common

2. Uses a backlight

3. Older models require an inverter to convert DC to AC power and use CCFL backlights

4. Single fixed native resolution

Common LCD Technologies

1. IPS (In-Plane Switching)

   1. Wide viewing angles

   2. Best color accuracy

   3. more expensive

2. TN (Twisted Nematic)

   1. Fastest response times

   2. Limited viewing anggles

   3. washed out colors

3. VA (Vertical Alignment)

   1. middle ground with good color and contrast

   2. Slower than TN

Characteristics of OLED

1. No backlight

2. Thinner, lighter, flexible designs

3. Generates own light when charged

4. enables true black

5. Higher contrast ratios

6. less power consumption

7. Susceptible to burn in

8. Shorter lifespan

Characteristics of Mini-LED backlights

1. Smaller, more densely packed LEDs

2. Offers excellent contrast

3. Achieve high peak brightness

What is the use of a touchscreen

To perform both input and output functions

What is the use of a digitizer

1. allows the control of a mobile device screen with a finger or a stylus

2. Responsible for input

3. Translates analog data into a format suitable for computer processing

What is the use of an inverter

1. Converts DC to AC power

2. Used for supplying voltage to backlights in older LCD panels

3. Essential for operating AC-powered devices from DC sources
