Increasingly, engineers are designing touch screens into their portable devices, Figure 1. Although battery technologies are becoming more efficient, it is critical to keep the power dissipation of ...

RIM have applied for a patent which details a hybrid touchscreen, combining both resistive and capacitive elements to improve accuracy as well as support multitouch, gestures and other functionality.

Resistive touch technology works by sensing direct pressure. Commonly used in touch-screen displays, a resistive touch-screen is typically activated by pressing with a finger or stylus. A resistive ...

The capacitive vs. resistive touchscreen dispute has been more or less settled with the popularity of the iPhone and other lozenge-shaped touchscreen devices, but that doesn’t mean the loser has to ...

Anyone who has tried to use a multi-touch touchscreen with anything other than their bare skin will know that it’s just not possible, no matter how hard you press. That’s because the capacitance ...

Touch-sensor specialists Peratech have announced their QTC Clear, a transparent version of their force-sensing touch panel which promises to bring 3D input and more to tablets, smartphones and other ...

Fig 1. Rohm’s BU21023/BU21024 series allows multi-touch detection in resistive touchscreens. Fig 2. David Lussey, Peratech’s CTO, demonstrates the transparency of the company’s QTC Clear material.

Remember when everything had a capacitive touchscreen, and we decided we really hated those and we wanted resistive ones that required styluses? Me neither. That’s why I’m a little puzzled as to why ...

Adjusting the volume dial on a sound system, sensing your finger position on a touch screen, and knowing when someone’s in the car are just a few examples of where you encounter variable resistors in ...

The AR1000 is a series of resistive touch screen controller which supports Universal Asynchronous Receiver/Transmitter (UART) communication. This series features power-saving sleep mode, built-in ...
