Touchscreen Technology

Which type of touchscreen technology resists your touch?

• Resistive
• Capacitive
• Infrared
• Optical

What are the two layers in a resistive touchscreen?

• Conductive and resistive
• Glass and plastic
• Copper and indium tin oxide
• Controller and electrodes

What happens when you touch a resistive touchscreen?

• The electric current changes at the point of contact
• The screen becomes more reflective
• The screen becomes harder to read
• The touchscreen stops working

Which type of touchscreen technology works with anything that holds an electric charge?

• Resistive
• Capacitive
• Infrared
• Optical

What materials are used in the construction of capacitive touchscreens?

• Copper and indium tin oxide
• Glass and plastic
• Conductive and resistive layers
• Controller and electrodes

How does a capacitive touchscreen work?

• By transferring a tiny electrical charge to the finger
• By reflecting ambient light to create a voltage drop
• By applying pressure to create a change in the flow of electricity
• By using infrared sensors to detect touch

Which type of touchscreen technology is more durable and consistent?

• Resistive
• Capacitive
• Infrared
• Optical

What is ambient light?

• The surrounding light reflected back from the screen
• The light emitted by the touchscreen
• The light absorbed by the touchscreen
• The light emitted by the user's finger

Which type of touchscreen technology is harder to read due to multiple layers?

• Resistive
• Capacitive
• Infrared
• Optical

What is the purpose of the electrodes in a capacitive touchscreen?

• To apply a low voltage to the conductive layer
• To create a uniform electrostatic field
• To protect the screen from scratches
• To record the location of voltage drops
