Screen Technologies and Panel Types

This set explores the differences between backlit LCD screens (IPS, VA, QLED, Mini LED) and self-lit displays (OLED, MicroLED, QDEL).

Backlit Screen

A display where light sits behind a panel and pixels act like blinds to control the amount of light passing through.

Edge-lit LED

A design where LEDs are placed around the frame of the TV, allowing for a thinner screen but often resulting in uneven light distribution.

IPS (In-Plane Switching)

A type of LCD panel known for wide viewing angles and stable colors, though it often suffers from more light leakage and gray-toned blacks.

VA (Vertical Alignment)

A type of LCD panel that provides deep blacks and high contrast by blocking more backlight, but loses image quality when viewed off-center.

QLED

An LCD screen that uses blue LEDs and a layer of quantum dots to produce more accurate and vivid red and green colors.

Quantum Dots

Tiny inorganic particles used as color converters to turn blue light into very pure red and green lights.

Mini LED

A backlight technology that uses thousands of small LEDs to create a dense grid of dimming zones for better contrast and reduced blooming.

Blooming

A visual artifact where light from a bright object spills over into surrounding dark areas, creating a halo effect.

OLED (Organic Light Emitting Diode)

A self-lit display technology where every individual pixel generates its own light and can turn off completely for perfect black levels.

W-OLED

A standard OLED panel type that uses a white OLED light layer combined with color filters to create images.

QD-OLED

A display tech that uses a blue OLED light source with quantum dots to produce color, resulting in higher brightness and better color saturation.

MicroLED

A self-lit technology using microscopic non-organic LEDs that combines the life-span and brightness of LCD with the black levels of OLED.

QDEL (Quantum Dot Electroluminescent)

An experimental display where quantum dots are the actual light source, designed to be brighter and more stable than organic OLED.
