When Microsoft is expected to launch the Windows 8 operating system in the second half of 2012, we can expect more existing and future products such as Ultrabooks, tablet computers, notebook computers, and personal brains to join touch technology and thus influence our lifestyle. , including interaction, work, games and information acquisition, etc. The focus of these developments is on the same component: touch screens. The technology of touch screens continues to improve, such as ToL and on cell technologies.
Further enhancements to the Android and iOS systems, together with the upcoming Windows 8, are ready to further expand the capabilities of the multi-touch interface. At the same time, equipment manufacturers face the pressure to improve display quality - by removing reflective and absorbing layers from the top, and by converting to active matrix organic light emitting diode (AMOLED) technology - for sensors used to resolve many touch activities. Impact, and these touch activities require touch interface support.
Implementing a Multi-Touch Interface with a Capacitive Touch Screen Solution The result of all these trends is the emphasis on capacitive touch screen solutions. In the past, people like resistive touch screens because they are relatively inexpensive to manufacture and support stylus-based input, and handwriting input is very useful for applications based on Asian text. However, resistive technology does not easily support multi-touch interfaces.
The resistive touch screen consists of an elastic top contact matrix layer, separated by a spacer and the underlying conductive layer. When a finger or a stylus presses the two layers together, a contact is formed and recorded by the electrical sensor. Internal reflections between multiple layers result in poor display visibility under sunlight, as well as lower overall brightness and color saturation. Because touch screens rely on the electrical contacts generated by the connection matrix, they cannot reliably detect more than one single touch activity.
