Passive-Matrix LCDs were standard in most early laptops (although a few used plasma displays) and the original Nintendo Game Boy
until the mid-1990s, when color active-matrix became standard on all laptops. Passive-matrix LCDs are still used today for applications less demanding
than laptops and TVs. In particular, these are used on portable devices
where less information content needs to be displayed, lowest power
consumption (no backlight) and low cost are desired, and/or readability in direct sunlight is needed.
Active-Matrix LCDs is a type of flat panel display, currently the overwhelming choice of notebook computer manufacturers, due to low weight, very good image quality, wide color and response time. Whereas a passive-matrix display uses a simple conductive grid to
deliver current to the liquid crystals in the target area, an
active-matrix display uses a grid of transistors and capacitors with the
ability to hold a charge for a limited period of time.
