Display

  • Touchscreen TFT-LCD
    • 4.3-inch (93.6 x 56.2 mm)
    • 800x480 widescreen (5:3)
    • Brightness: 300 cd/m2
    • Contrast ratio: 450:1
      • Viewable in direct sunlight, but it will wash out.
    • Response time: tr+tf=30ms
      • No ghosting.

The Pandora uses the same LED screen as the Archos 605.

What kind of touch screen does it have? Is it multi-touch?

The Pandora touchscreen is resistive. Resistive touchscreens cannot do multitouch like the iPhone or iPod Touch can, but they can do simplistic pressure sensing. Resistive touchscreens use a stylus for input, which is included. You can also use your finger for less accurate tasks, such as pressing buttons. It is very easy and natural to switch between gaming controls to touchscreen.

Can I draw using the touch screen?

Notaz, who was working with the touch screen driver, says it can do some pressure sensing and returns around 16 different values for pressure[1]. This is not sensitive the way Wacom tablets are, but should allow simple pressure sensitivity if applications are designed for it. For software development, it is accessible through standard Linux event interface (raw values), or tslib (calibrated).

Why doesn't the LCD touchscreen flip / rotate for a "tablet" mode?

This idea is patented.

Pandora could not have a hinge which either flipped all the way back or rotated without substantially increasing the cost through patent licensing fees.
