Tech Global's Dynamic-Touch Surface Capacitive Touch Screens: Tech Global's Dynamic-touch Surface Capacitive Touch Screens are an all-glass construction with greater than 9H Surface hardness able to withstand over 300 million touches. A transparent conductive ITO coating is evenly distributed over both sides of a glass substrate. An electrode pattern is precisely printed around the perimeter of the glass to accurately generate an alternating current over the top conductive layer. The touch of a conductive probe draws the current to the specific point of contact. The controller then calculates the location of the touch by evaluating the flow of current from each corner. This flow of current is proportional to the distance to the touch. The ITO coating on the back of the glass functions as a shield to protect against ESD and outside interference. With no mechanical movement and a 9H surface hard coat, a capacitive touch screen can withstand 300 million touches. Differentiation: Optical Performance is 93% - Industry Best Accuracy is 99% in Viewing Area Long Life - 300+ Million Touch Activations Compatible - Drivers to support all Windows Operating Systems including CE, Xpe and Linux Also works with Medical Gloves Tech Globals' surface capacitive touch screens provide a transparent protective coating makes the sensor resistant to scratches and abrasions. Touch performance is unaffected by everyday abuse and mishaps such as dirt, dust, condensation, liquid spills, contaminants or cleaning solutions. And this is the only surface capacitive touch screen that is medical glove touch capable and is the most durable touch screen on the planet.

Responsible Partners: Tech Global, Inc. partners with NEC. In the U.S. and on a global scale, Tech Global, Inc. and NEC play a pivotal role in the spearheading, development and education of environmental initiatives in the display industry. For over 30 years NEC Display Solutions has been at the forefront of modern display technology. For the last 15 years, NEC Display Solutions has worked with the Environmental Protection Agency on the development and implementation of the ENERGY STAR standard.Since the early 90s, we have been a leader in designing desktop monitors that meet or exceed ENERGY STAR standards. By following these standards and educating our customers about the benefits of using energy-efficient equipment, NEC Display Solutions helps to lower the monitor’s overall operating cost while increasing the lifespan of the product. In addition to offering cost-saving alternatives, NEC is leading the way by providing our customers with the most environmentally friendly display products available today.For more information, visit:http://www.energystar.govNEC Display Solutions and ENERGY STAR®Tech Global and NEC have accomplished its environmental initiatives in three ways: Reduction: . We have proactively reduced the number of contaminants in our products. Materials such as mercury have been reduced significantly. . We have developed leading-edge lighting technology that permits up to a 50% reduction in display power consumption. Re-Usage: . Use of recycled paper for product manual printing . Resale of refurbished component parts . Since the Total Trade™ program began, we estimate that NEC has recycled more than 5 million pounds of materials. Recycling: . Use of more expensive, more easily disposed of plastics. . Contributed to the EPA’s ENERGY STAR recycling guidelines for displays. . Recycling events ...read more

Presented by Tech Global, Inc. The primary difference from a 5-wire touch screen is that each edge of an 8-wire Resistive Touch Screen provides a sensing line as a stable voltage gradient for the touch screen controller. The additional 3 lines enable the controller to automatically correct for drift resulting from degraded ITO conductive coating or additional electrical resistance due to harsh environments and extended use. The extra sensing lines constantly report back to the controller the actual "baseline" voltage levels that exist in the touch area. If the baseline voltage changes over time, the controller is able to interpret the voltage change sensed during a touch event as a percentage of the baseline, thus eliminating drift and the need for field calibration. The 8-wire Resistive Touch Screen consists of a conductive bottom layer of either glass or film and a conductive top film layer, separated by extremely small, transparent spacer dots. A voltage is applied across the conductive surface. Any type of probe, including fingers, gloved fingers, credit cards, pens, etc., that can be used to apply pressure against the top film will activate the screen. When ample touch pressure is applied to the top layer, the film flexes inward and makes contact with the bottom layer resulting in a voltage drop. This change in voltage is detected by the controller. As defined above, the voltage change is interpreted in relation to the baseline voltage as sensed by the additional 3 wires. By alternating the voltage signal between the top layer and the bottom layer, the X and Y coordinates of the user's touch are computed. ...read more
