An OGS display is a display assembly that uses a One Glass Solution (OGS) touch panel.<\/strong> In this design, the capacitive touch sensor is formed on the protective cover glass, so the touch panel does not need a separate glass sensor substrate. The display underneath still creates the image; OGS describes how touch is integrated, not the display’s pixel technology.<\/p>\n\n

For an equipment designer, the practical question is whether an OGS touch assembly fits the product’s space, optical, touch, and service requirements. Its potential to reduce the touch stack can be useful, but the finished module still needs to be checked as a complete system.<\/p>\n\n

How does an OGS touch display work?<\/h2>\n

A capacitive touch controller measures changes in capacitance associated with a finger near the sensor electrodes. It processes the signals and reports touch positions to the host. In an OGS design, the electrodes are formed on the cover glass, often with a transparent conductive material such as indium tin oxide (ITO). A flex cable carries the sensor signals to a touch controller, which communicates with the host.<\/p>\n

The cover glass and its electrodes form the touch assembly. An LCD or another display panel beneath it produces the image. Synaptics describes this cover-glass approach as OGS or sensor on lens.[1]<\/a><\/sup> Actual electrode patterns, controller placement, and construction vary by supplier. Terminology such as touch on lens can also vary with the manufacturing process.<\/p>\n

\u201cOne glass\u201d does not mean that the complete display module contains only one piece of glass. An LCD panel can have its own glass substrates in addition to the OGS cover.<\/p>\n\n

What are the potential advantages of OGS?<\/h2>\n
