WHAT IS… A CAPACITIVE TOUCHSCREEN? A capacitive touchscreen panel is coated with a material that stores electrical charges. When the panel is touched, a small amount of charge is drawn to the point of contact. Circuits located at each corner of the panel measure the charge and send the information to the controller for processing. Image processing controller Capacitive touchscreen panels must be touched with a finger, unlike resistive and surface wave panels that can be operated by either fingers or stylus. Capacitive touchscreens aren’t affected by outside elements and have high clarity....

WHAT IS… A RESISTIVE TOUCHSCREEN? A resistive touchscreen panel is coated with a thin, metallic, electrically conductive and resistive layer. This causes a change in the electrical current which is registered as a touch event and sent to the controller for processing. Resistive touchscreen panels are generally more affordable and work well with almost every stylus-like object. They aren’t affected by outside elements such as dust or water, can even be controlled by gloved hands and are therefore the ideal companion for rugged PCs. Touchscreen controller Resistive coated glass substrate...

WHAT IS… A DIGITISER TOUCHSCREEN? Digitiser touchscreens make use of electromagnetic induction technology, where the horizontal and vertical wires of the screen operate as both transmitting and receiving coils. The tablet generates an electromagnetic signal, which is received by the stylus. The wires in the tablet then change to a receiving mode and read the signal generated by the stylus. Modern arrangements also provide pressure sensitivity and one or more switches (similar to the buttons on a mouse), with the electronics for this information present in the stylus itself, not the tablet....

WHAT IS… A ‘TRANSFLECTIVE PLUS’™ DISPLAY? A transflective display reflects and transmits light (transflective = transmissive + reflective). Under bright illumination, the display acts mainly as a reflective display with the contrast being constant with illuminance. Only in dim and dark ambient situations will an auxiliary transmissive backlight be provided. A transflective LCD can be read over a wide range of illuminance levels, when an illuminance sensor is added for control of the backlight. In portable electronic devices the transflective mode of operation helps to save battery life,...

WHAT IS… DUAL TOUCH? Dual touch is the combination of capacitive touchscreen and digitiser technology. It enables the operator to use the GUI with fingers, as well as with a digitiser pen. The key benefit of this combination is the intuitive handling via finger and the accuracy (signature capture, handwriting recognition) of the pen providing the flexibility to choose the right display input mode on demand.

WHAT IS… MULTI-TOUCH? Multi-touch is a method of input on a touchscreen that allows two or more fingers to be used on the screen at one time. Multi-touch allows pinching and stretching gestures on the screen to control zooming. A multi-touch display is pressure sensitive, as well as gesture sensitive, which are predefined motions that are commands to perform an action, such as rotate the object on the z-axis.

WHAT IS… IPS? In IPS (In-Plane Switching) technology the liquid crystal runs horizontally, giving it a wide viewing angle, fast response speed and a simple pixel structure. IPS panels employ pairs of electrodes at the sides of each cell, running the electric field horizontally through the material. This approach keeps the liquid crystals parallel to the front of the panel, increasing the viewing angle. IPS PANEL DESIGN Front glass CONVENTIONAL Loss of contrast and colours appear washed out. IPS Virtually no change in contrast and colour.

Circular polariser film passes only horizontally polarised light • Retardant film converts horizontal polarisation to right-handed circular polarisation • Upon reflection, right-handed polarisation changes into left-handed polarisation • Retardant film converts left-handed polarised light to vertically polarised light • Polariser film rejects vertically polarised light • Outbound light from the LCD is horizontally polarised, so it can pass all the way through (in fact, direction polariser film is chosen to match LCD polarisation) The main effect is that sunlight is adsorbed and the...
