Capacitive Touch Screen

Capacitive touch screens are the core line of this site: the store category is listed as PCAP and TFT screens, and the website's navigation lists CTP capacitive touch screens as its first product group. This page describes the category in general terms — what capacitive touch covers, where it is used, and what a buyer should confirm before ordering.

What this category covers

Capacitive touch screens detect touch through changes in an electrostatic field at the cover surface, which is why they respond to a light touch and support multi-touch gestures. The category here covers projected capacitive (PCAP) screens and CTP capacitive touch screens, in the website's own grouping, together with the related capacitive touch display line.

This page also carries the concept of the capacitive touch panel line. Buyers searching for capacitive touch panels will find the same category scope here: a touch surface built around a capacitive sensor, a cover glass, and a controller board that reports touches to the host system.

Where capacitive touch fits

Capacitive touch is the usual choice where the interface must feel immediate and support gestures — control panels, information terminals and equipment interfaces where operators expect a smartphone-like response. It is less usual where the operator must wear very thick gloves or where the surface is constantly wet, and those cases are covered by the glove and waterproof pages, which describe the website's stated support for those conditions.

For industrial use, the deciding factors are usually the cover glass, the bonding method and the controller interface rather than the sensing principle alone. The industrial touch screen page sets out the industrial angle, and the projected capacitive page explains the technology in more depth.

What to confirm before ordering

Please confirm the cover glass shape and optical treatment, the bonding method, the controller interface, and the operating environment before ordering. Please also confirm the minimum order quantity and the delivery schedule before payment. Certificates available upon request. Please ask for the documents your project requires and confirm them before ordering.

• Confirm the cover glass shape and whether AG, AR or AF treatment is needed
• Confirm full lamination or frame lamination
• Confirm the controller board interface
• Confirm glove, water or oil exposure in the operating environment
