8 Inches and larger Tablets released in 2010: Comparison Chart

As of 2011, the usual tablet computer display size is 10" (for iPad and Android Honeycomb tablets) or 7" (for many Android 2.x tablets). Many tablet PC makers have standardized on a 12" widescreen format, with a resolution of 1280×800 pixels. The Fujitsu T5010 has a larger 13.3" display, but still runs at the 1280×800 pixel resolution. The Acer TravelMate C300 has a 14.1" screen at 1024×768. In April 201, Sony has announced Honeycomb Android Tablet S2 with dual 5.5-inch screens

Display Touchscreen hardware

Touchscreens are usually one of two forms;

  • Resistive: Resistive touchscreens are passive and can respond to any kind of pressure on the screen. They allow a high level of precision (which may be needed, when the touch screen tries to emulate a mouse for precision pointing, which in Tablet personal computers is common) but may require calibration to be accurate. Because of the high resolution of detection, a stylus is often used for resistive screens. Although some possibility exist for implementing multi-touch on a resistive touch-screen, the possibilities are quite limited. As modern tablet computers tend to heavily lean on the use of multi-touch, this technology has faded out on high-end devices where it has been replaced by capacitive touchscreens.

  • Capacitive: Capacitive touchscreens tend to be more accurate and responsive than resistive screens. Because they require a conductive material, such as a finger tip, for input, they are not common among (stylus using) Tablet PCs but are more prominent on the smaller scale "tablet computer" devices for ease of use, which generally do not use a stylus, and need multi-touch capabilities.

Other touch technology used in tablets include:

  • Palm recognition. It prevents inadvertent palms or other contacts from disrupting the pen's input.

  • Multi-touch capabilities, which can recognize multiple simultaneous finger touches, allowing for enhanced manipulation of on-screen objects.
Some professional-grade Tablet PCs use pressure sensitive films that additionally allows pressure sensitivity such as those on graphics tablets
