What is the purpose of the polarizing filter in an LCD?
What is the purpose of the polarizing filter in an LCD?
- To provide a reflective surface for the display
- To align the layers in contact with the liquid crystal
- To create the transparent electrode pattern
- To control the amount of light passing through the liquid crystal (correct)
What happens if there is no liquid crystal between the polarizers in an LCD?
What happens if there is no liquid crystal between the polarizers in an LCD?
- The liquid crystal would not be able to align properly
- The crossed polarizers would block out the light, making the screen appear dark (correct)
- The polarizers would allow all light to pass through
- The screen would appear brighter than usual
What effect do adjusting the voltages on the electrodes have on the LCD?
What effect do adjusting the voltages on the electrodes have on the LCD?
- It alters the transparent electrode pattern
- It changes the color temperature of the display
- It changes the amount of twist in the liquid crystal and varies the amount of light passing through (correct)
- It modifies the alignment layers in contact with the liquid crystal
