passive matrix display
Noun: A type of liquid-crystal display (LCD) technology where pixels are controlled by a simple grid of conductive wires. A pixel is activated only when the two wires (one horizontal and one vertical) that intersect at its location are both energized. This method is less efficient and slower than active matrix technology, often resulting in poorer image quality, such as slower response times and less vibrant colors.
This term is a technical noun used to describe a specific display hardware technology, primarily in the context of electronics and computing. * Early laptop computers often used a passive matrix display to save cost and power. * The main drawback of a passive matrix display is its slow refresh rate, which can cause a visible trailing effect when the cursor moves.
- The term is often used in a comparative context with its successor technology, the active matrix display.
- For tasks requiring fast-moving graphics, an active matrix display is vastly superior to a passive matrix display.
- Passive matrix: A common shortened form of the term.
- The device features a color passive matrix screen.
- Active matrix display (noun): The contrasting, more advanced display technology where each pixel is controlled by its own dedicated transistor, resulting in better performance.
- Dual-scan display: A specific, improved type of passive matrix technology.
- CSTN (Color Super-Twist Nematic) display: A common color implementation of passive matrix technology.
- Response time: A key performance metric where passive matrix displays typically perform poorly.
- Refresh rate: The speed at which the image is redrawn on the screen; often lower in passive matrix designs.
- Pixel ghosting: A visual artifact commonly associated with the slower switching of pixels in this display type.
-
a type of LCD display used for some portable computers; parallel wires run both vertically and horizontally and pixels are turned on when the wires intersecting at that pixel are both energized
-
passive matrix displays are generally inferior to active matrix displays
