passive matrix LCD
A type of LCD display technology where pixels are controlled by a grid of row and column electrodes without active switching elements at each pixel. Used in older or simpler LCD panels.
Early laptop computers used passive matrix LCDs.
Passive matrix LCDs have slower response times compared to active matrix LCDs.
Active matrix LCD technology, which uses thin-film transistors at each pixel for faster response and better image quality, in contrast to the simpler passive matrix approach.
Compound of 単純 (simple) + マトリックス (matrix) + 方式 (method/system), a direct calque of the English term 'passive matrix'.
