Question 12

The refresh rate is the number of times a display’s image is repainted or refreshed per second.

Answer 12

True

Question 13

OLED

Answer 13

Uses an organic substance as the semiconductor material and uses a series of thin, light-emitting films on which when an electrical current is applied, photons move through the organic substance and emit a bright light

Question 14

What are the primary layers of an OLED display.

Answer 14

• The substrate which acts as the structural framework.
• The anode which draws electrons
• The organic layer, which contains two sublayers.
