What does LCD stand for?

• Low Contrast Definition

• Liquid Crystal Display

• Light Control Device

• Luminous Colorful Display

What is the function of the backlight in an LCD display?

• Provides light to individual pixels

• Enhances the contrast ratio

• Controls the color temperature

• Regulates the screen resolution

How do LCD displays differ from CRT monitors?

• Use a twisted liquid crystal layer

• Operate by backlight technology

• Have a rectangular grid of pixels

• Do not fire electrons at a glass screen

What happens when all sub-pixels of a pixel in an LCD display are turned off?

• It appears black

• It appears white

• It displays a rainbow effect

• It shows a grid pattern

What technology is commonly used in modern LCD screens for better performance?

• Passive-matrix

• Thin-film transistors

• LED backlight

• CRT technology

What is the main advantage of active-matrix LCD displays over passive-matrix screens?

• Higher energy consumption

• Individual pixels retain their charge

• Slower response time

• Blurry image quality

What is the difference between an LED display and an OLED display?

• LED displays use individual LEDs for each pixel

• OLED displays have a traditional bulb backlight

• OLED displays are known for blurry images

• LED displays have a passive-matrix screen

What is the purpose of liquid crystals in an LCD display?

• Reflect red, green, or blue light

• Block the polarized light when off

• Provide an even light source

• Control the color temperature

What is the function of thin-film transistors in active-matrix LCDs?

• Twist the liquid crystal layer

• Enable individual pixels to retain their charge

• Control the backlight intensity

• Enhance the contrast ratio

Why do OLED displays typically have darker black levels than LCDs?

• Liquid crystals block most of the backlight

• Due to the use of a traditional bulb backlight

• OLEDs light up individual LEDs for each pixel

• Because OLEDs have a slower response time
