Mobile Display Types and Components Notes

These flashcards cover essential vocabulary and definitions related to mobile display types, components, and technology as outlined in the notes.

Liquid Crystal Display (LCD)

A flat panel display that is backlit, producing images by allowing or blocking light to pass through.

Twisted Nematic (TN)

A technology used in early LCDs, known for low operating voltages and used for monochrome displays.

Vertical Alignment (VA)

An LCD technology that produces a truer black and offers a wider viewing angle but may have color distortion.

In-plane Switching (IPS)

A technology used in LCD televisions with a high response rate, ideal for touchscreen displays.

Organic Light-Emitting Diode (OLED)

A display technology that emits light for deep blacks and high contrast, allowing for thinner and lighter screens.

WiFi Antenna Connector

Used in displays to connect wires for the WiFi antenna, facilitating signal strength.

Camera/Webcam

Integrated camera in displays for web chats and tele-meetings, often located at the top-center of the display bezel.

Touch Screen/Digitizer

Allows finger input on laptops; can be embedded or placed as a glass layer over the display.

LCD Inverter

Converts DC power to AC power for LCD backlighting, ensuring adequate illumination.

Power States in ACPI

Describes operational states of devices: Working (operational), Standby, Sleep, Hibernate, and Off.

Preferred Roaming List (PRL)

A database in CDMA devices that facilitates system selection and acquisition based on radio bands.

Global System for Mobiles (GSM)

A standard for mobile communications that operates using SIM cards for network identification.

5G Technology

The latest generation of mobile networks achieving peak speeds of 20 Gb per second.

Hotspot

A physical location providing wireless internet access via WLAN.

Tethering

Connecting one device to another to share internet connections.

Near-Field Communication (NFC)

A low-speed wireless communication method for transferring data over short distances.

Memory Types

Includes internal storage variations, memory access types, and considerations for SSDs and HDDs.

Network Types

Classifies networks by geography, management, and method of connection between devices.

RAID 0 (Striping)

A RAID level that strips data across disks for performance but lacks redundancy.

RAID 1 (Mirroring)

A RAID level that copies data onto two or more disks for fault tolerance.

RAID 5 (Striping with Parity)

A RAID level combining striping and parity distribution for additional data redundancy.
