In addition to the manufacture of more than 100 standard product types, DMC strives for close communication with customers from the design stage to develop touch screens suitable for individual environments and conditions. DMC also offers a wide variety of optional products that reinforce touch screen functions and improve usability to offer even greater product value.


Resistive single-touch type detects points touched with fingers or a pen by measuring changes in voltage. It is easy to use, and it features reliable operability. Operation with gloves or pen is possible. In addition to a single-touch type, we offer a multi-touch type that expands the range of operability.

Resistive touch screens have a two-layer structure. Materials such as film and glass with ITO are attached with a gap in between so that the ITO layers face each other. Touch input is accomplished as the top layer is pressed down to bring the two ITO layers into contact. There are insulators called spacing dots between the top and bottom ITO layers. These spacing dots prevent unintended contact (inputs) of the ITO layers when not pressed. One of the two ITO layers creates the X-coordinate circuit while the other layer creates the Y-coordinate circuit. As indicated below, the X-electrodes form the top layer while the Y-electrodes form the bottom layer.

X(+) is Vcc (5V) while X(-) is Ground (0V). Voltage is applied between the X(+) and X(-) electrodes. When the screen is touched (pressed), the voltage of the X-coordinate on the top layer is detected at the Y-electrode (A_in) on the bottom layer. For example, if Point A is pressed, an X-coordinate voltage of 2.5V is detected at A_in on the bottom layer. The detected voltage is converted into digital data (A/D conversion), and the coordinate position of the X-direction is recognized. When voltage is applied between the electrodes Y(+) and Y(-), the touched point of the Y-direction is recognized in the same manner as the X-direction; and the voltage of Y-coordinate is detected on the top layer. The detection processes of the X and Y-coordinates is repeated alternately in order to detect the input point.

The resistive single-touch type requires physical pressure for data input to prevent input errors caused by operational mistakes and malfunctions caused by environmental factors. This stability has resulted in the highest share for industrial and business use. In addition, the high durability of DMC resistive touch screens (10 million touches guaranteed) has garnered strong customer loyalty.


The resistive multi-touch type realizes multi-touch gesture operations while maintaining the stability of resistive touch screens. Recently, smart phones and tablets with capacitive touch systems are commonly used and the demand for modern operability such as multi-touch and gesture operations has been increasing in the industrial- and business-use touch screen markets. Unlike resistive touch systems, however, capacitive touch screens are influenced by noise from the surrounding environment, a problem that makes some users hesitate to replace their terminals with capacitive touch system due to concerns about stability. To respond to such concerns, DMC combined the stability of the resistive- and multi-touch systems to produce a resistive multi-touch type. This enables a multi-touch system by dividing the touch screen into vertical and horizontal cells.

One cell functions the same as a part of the resistive touch screen. In the example shown above, 180 small screens are combined to form one large touch screen. DMC customized solutions for resistive touch systems respond to a wide range of market needs. One increasingly popular solution is a touch screen with overlay film.

Laminating the resistive touch screen without leaving any air between the ITO film on the top layer and design-printed overlay film allows the easy creation of stylish bezel-less flat interface designs like those seen on smart phones while maintaining transparency and sensitivity.


Capacitive multi-touch type detects points touched by finger utilizing capacitive couplings generated by touch. It provides excellent operational smoothness, visual clarity, toughness and weatherability. We offer multi-touch type screens.

Projected capacitive touch screens are employed in smart phones and tablets. When a finger contacts the touch screen, the projected capacitive type detects the touched point by measuring the changes in capacitive coupling. The light-touch operability and flicking, and gesture operations such as zooming, and rotating by multiple touch are available. Adding a cover glass realizes a flat and modern interface to increase the appeal of this popular type. A standard product lineup from 5.7 to 32 in. capacitive touch screens means the best sizes are available for a wide range of purposes to reduce time and cost. DMC also produces large-size touch screens measuring more than 32 in. for the digital signage and public display markets.

People and Language Lead to the Creation of New Values

Contributing to smooth communication with multi-language touch screens

Action by the Japanese government designed to increase Japan's appeal as a tourism advanced country has been accelerated to establish an environment that enhances visitor convenience and satisfaction. According to the results of a 2016 Japan Tourism Agency questionnaire targeting tourists from abroad, the most frequently mentioned difficulty during stays in Japan was communication with facility staff, and the third most frequent concern was having only a few signs in different languages and signs that are hard to understand. Touchscreen devices can be operated intuitively, and switched into different languages at a moment to solve the above-mentioned problems. DMC cooperates with touchscreen manufacturers to develop and produce touchscreens suitable for the multi-language devices.

DMC places a priority on detailed responses to customer requests.

DMC works in close cooperation with engineers and other staff at our factories to keep abreast of touchscreen market needs. Equipment with multi-language touch screens is suitable for outdoor use by the general public. Therefore, these adopt electrostatic capacity touch screens that feature high durability and weather resistance. DMC exerts its strength in in-house development including sensor controllers to ensure a detailed response to customer requests that mass-produced all-purpose products cannot accommodate. We continue developing products that meet ever-changing needs.


DMC Proposals for Solutions

There is a wide range of touch screen systems, and each system has both advantages and disadvantages. DMC manufactures the most frequently used resistive and capacitive touch screens. As the requirements for touch screens have become increasingly diverse and application has expanded to a wide range of fields, resistive and capacitive touch screens are responding to industrial use requirements such as environmental tolerance, durability, gloved-hand operations, multi-touch, outdoor use with direct exposure to sunlight and water. We focus on the manufacture of both resistive and capacitive touch screens to satisfy wide ranging customer needs in a well-balanced manner.

DMC also handles overlay film and cover glass customization, support for controller adjustment, and unique solutions for the original DMC touch driver that is capable of controlling and managing both resistive and capacitive touch screens at the same time. This allows DMC to provide products for use in many industrial and business settings.

Sample Solution 1

Collective control for KIOSK terminals operated by customers and staff with one driver

When controlling multiple touch screens such as KIOSK terminals operated by customers and staff, the DMC touch driver DMT-DD allows the establishment of a stable multi-monitor environment as well as the set-up and management of a wide range of functions that are usually not included in the regular Windows driver, functions such as "touch mode/ mouse mode," "reversal/ rotation of coordinates," and "touch sound" for individual touch monitors. This is the ideal solution for controlling multiple touch monitors such as KIOSK terminals at stores, ticket machines at stations, and reception terminals at hotels.

Sample Solution 2

Resistive multi-touch type with full-flat overlay

The highly-stable resistive touch screen is employed extensively in industrial settings. Due to the popularization of smart phones and tablets, the demand for multi-touch and bezel-less designs has increased. While such functions and designs are also possible with capacitive systems, they have been avoided for industrial use because of their susceptibility to environmental noise. To address this disadvantage, DMC added overlay film to resistive multi-touch type screens to realize multi-touch function and bezel-less design.

Sample Solution 3

DMC standard glass-structure capacitive touch screens offer high durability and weather resistance

DMC standard capacitive touch screens have a double-layer glass structure. Because of their high durability and weather resistance, they are ideal for terminals used by general public and those installed outdoors; and adding thick tempered glass to the top of the screen significantly increases strength.
