Innovative touch LCD panel embeds touch key inside LCD cell
andersDX has launched new LCD with in cell touch technology, where each LCD cell is embedded with in cell touch key. This is different from present touch sensors where touch sensor is bonded onto the LCD display. andersDX says this feature differentiates the end product user interface with technical and commercial benefits.
andersDX offers LCD ITO pattern to match individual touch key symbols. An Atmel Q touch sensor IC integrated into the display electronics controls up to 4 touch keys per application. andersDX claims the detection is extremely accurate and the accuracy is maintained through self calibration and auto drift compensation. The simple self-capacitance sensor design can sense through glass up to 10 mm thick, or plastic of up to 5 mm. It operates from 1.8 to 5.5 Vdc, as per andersDX.
Since there is no external layer on the LCD panel, the display can be brighter and also thinner . The display can also be fitted with hardened glass.
The key advantage of this product as per andersDX is, it has a technology in offering not-so-expensive LCD panels of this type for small volume use. It can be offered at extremely aggressive pricing compared to traditional capacitive sensing touch key solutions, with very low MOQs, says andersDX.
andersDX gives an industrial system example where a heating controller with temperature-up and temperature-down arrows, achieved without external buttons or a full bonded sensor. Other applications suggested include White Goods, Consumer, Instrumentation and Control Panels.
“We have been providing custom LCD solutions for over 40 years” commented Paul Mullen, Sales Director at andersDX, “and with In-Cell Touch we continue to differentiate our customers’ products through innovative and novel technologies”
