Importance of VDU in modern technology

VDU is an important component of modern technology. They are used in everything from personal computers and smartphones to industrial machinery and medical equipment.

VDU types

CRT (Cathode Ray Tube) VDU
CRTs work by firing a beam of electrons at a phosphor-coated screen. This causes the phosphor to emit light and form the image. CRTs have excellent color accuracy and contrast, but they are heavy and consume a lot of power.

LCD (Liquid Crystal Display) VDU

LCDs work by using liquid crystals to block or allow the passage of light. They need a backlight to produce an image. LCD VDUs are lighter and consume less power than CRT VDUs, but they have limited viewing angles and color accuracy.

LED (Light Emitting Diode) VDU

LEDs work by using light emitting diodes to produce a VDU image. LEDs have excellent color accuracy and consume less energy than both CRTs and LCDs, but LEDs can be expensive.
