Novel multifunctional capacitive touch screen

Abstract

The invention discloses a novel multifunctional capacitive touch screen. The screen includes Cover Lens glass, a flexible printed circuit (FPC), Sensor glass and EMI glass which are arranged from topto bottom in sequence, wherein the Cover Lens glass is fixed with the flexible printed circuit (FPC) through OCA join adhesive, the Sensor glass is also fixed with the EMI glass through OCA join adhesive, and gold wires are pulled out from the Sensor glass to be connected with the FPC. The upper surface and lower surface of the EMI glass are plated with a layer of ITO membrane separately, the resistance value of the ITO membrane on the upper surface of the EMI glass is smaller than 15 ohms per square resistance, and the ITO membrane on the upper surface of the EMI glass serves as an electromagnetic shield; the ITO membrane on the lower surface of the EMI glass serves as a heating resistor. The novel multifunctional capacitive touch screen improves electromagnetic shielding, low-temperaturefast starting and other military environmental requirements for military on-board displayers, and meanwhile reduces the operation process difficulty of the on-board displayer products.

Description

technical field [0001] The invention relates to the field of touch screens, in particular to a novel multifunctional capacitive touch screen. Background technique [0002] With the development of science and information technology, touch screen, as the latest human-computer interaction technology, has penetrated into every aspect of people's life and has been applied to airborne display systems. Because the touch screen, as the latest input device, is currently the simplest, most convenient, natural and comfortable input device. It has many advantages such as fast response, space saving, durable, and easy communication. It is these many advantages that countries generally pay attention to, and invest a lot of manpower, material and financial resources in research and development, and new touch screens appear continuously. The touch screen presents the trend of specialization, three-dimensional, large screen, high integration and high reliability. It can be predicted that w...
