Quality and support based on 30 years of experience

NISSHA's touch screen

NISSHA has been supporting customers for over 30 years as a manufacturer of touch screens.
We supply touch screens for mobile phones and game consoles, as well as industrial devices and automobiles.
NISSHA touch screens based on plastic film have not only the unique features of a film sensor, such as thin, light and unbreakable, but also high transparency comparable to glass sensors. We provide high-quality, high-value-added touch screens based on our many years of experience and experience cultivated as the frontier of touch screens.

NISSHA’s Capacitive touch screen

Thin and high-performance film-type touch screen

NISSHA’s touch screen is a film type capacitive touch screen.
When a finger touches the surface of the panel, the capacitance (charge) between the transparent electrodes changes and touch position is recognized
NISSHA’s unique photo etching technology realizes a thin, highly transparent, high-performance capacitive touch screen

Thinner touch screen module by double-sided etching

In a general capacitive touch screen, a sensor module is formed by bonding two transparent electrode substrates for X-axis electrodes and Y-axis electrodes with an adhesive.There were problems with this manufacturing method, in which two electrode substrates and an adhesive were laminated, such as “Thickness increases” “Optical characteristics deteriorate” ” Difficulty to improve pattern positional accuracy.”

NISSHA has introduced a process of photo-etching a metal thin film formed on both sides of a film substrate, and has developed a technology to consolidate sensor patterns on a very thin film with a thickness of 100 μm. The touch screen module has been made thinner.
Furthermore, the adoption of photo-etching processing makes it possible to configure minute sensor patterns with extremely high positional accuracy.

Comparison of layer structure between general touch screen module and NISSHA touch screen module

COP film substrate with excellent optical properties

COP (cycloolefin polymer) is used for the base film.
COP film has high transparency and excellent optical isotropy, so it is a substrate with few visibility problems such as Newton rings (rainbow view).
There is little reflection, and the image on the display can be displayed more vividly.

Fine wiring by simultaneous photo-etching of ITO / Cu

NISSHA’s photo etching process patterns the transparent electrode (ITO) and the lead wiring (Cu) in one process. As a result, it is possible to align the ITO electrode and the Cu wiring with high positional accuracy. Furthermore, by drawing a fine pattern of Line / Space = 10/10 μm, a narrower frame that minimizes the area of ​​the lead-out wiring is realized. The sensor area has been extended to the edge of the display.

Module integrated with cover panel and LCD

We have accumulated various process know-how for punching film touch screen patterned by the roll-to-roll method into individual pieces and processing them into the form of modules that can be mounted in the final product.
We deliver not only film sensors but also composite modules with cover glass and LCD attached in a form that meets the needs of our customers.

Innovation of NISSHA capacitive touch screen

NISSHA has been working on the development of touch screens to realize what customers want to make. We will contribute to customer product development through the development of capacitive touch screens with the following features that have been considered difficult to date.

  • Input with gloves on
  • Use in harsh environments such as humid or water around where equipment may get wet
  • Use in places where electromagnetic noise is severe

Support for various input methods

  • Pen input support
  • Prevention of malfunctions caused by fingers during pen input (Palm Rejection function)

Wider and larger sensing area

  • Increased effective sensing area by miniaturizing frame wiring
  • Compatible with large screens up to 32 inches

Shape freedom for curved surfaces

  • Can be attached to 2.5D shape cover panels

High Product and Service quality

NISSHA supports custom manufacturing of capacitive touch screens.
Requests from customers are consistently supported by the project team from design study to prototype production and mass production support.

Design review system to ensure quality

We organize a project team for each project and support from design study to prototype production to mass production.

Enhanced quality / delivery support after mass production

We provide fine-grained after-sales support based on our ability to cultivate business with demanding customers such as smartphones and in-vehicle devices.

Mass production technology that guarantees high quality

It adopts a roll-to-roll manufacturing process with excellent processing accuracy and supports mass production with little quality variation.
