Liquid Crystal Display

A display technology where light shines through liquid crystals to produce images.

Advantages of LCD

Lightweight, relatively low power consumption, and relatively inexpensive.

Disadvantages of LCD

Challenges with black levels, requires a separate backlight, and difficult to replace lights.

TN (Twisted Nematic) LCD

The original LCD technology known for fast response times but poor viewing angles.

IPS (In Plane Switching) LCD

LCD technology with excellent color representation but more expensive than TN.

VA (Vertical Alignment) LCD

A compromise between TN and IPS with good color representation and slower response times.

OLED

Organic Light Emitting Diode technology that emits light from organic compounds upon electric current.

Advantages of OLED

Thinner and lighter than traditional displays, flexible, and no backlight is needed.

Wi-Fi antennas

Multiple antennas used for WiFi main and aux/Bluetooth connections, often wrapped around the laptop screen.

Near-field communication (NFC)
