passive matrix display การใช้

• The debut year for the duo only offered a passive matrix display on both the mid-level and high-end models.
• It was 8 MHz faster than its predecessor, the ADB port and used a lower quality passive matrix display than other current offerings, both to reduce the price.
• It was the first mobile phone to use a thin-film transistor active matrix LCD display; prior to the release of the SGH-T100 all phones had used passive matrix display technology.
• In contrast to the high end of the 100-series line with which the Duos shared the same processors, the PowerBook 170 and 180 with their crisp active matrix displays were both already in great demand over the lower powered models with passive matrix displays.
• Whereas a passive matrix display uses a simple conductive grid to apply a voltage 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.
