Frequently Asked Questions

  • What is required for touch screen use?

    Touchscreen, controller, controller cable and driver software are required. In addition, a host computer in which the driver software can be installed and a monitor on which the touch screen can be mounted are necessary.

    e.g.) For a 15-in. touch screen via USB connection

    AST-150A080A (touch screen)+TSC-54/RU (touch controller)+TSC-10/SC (controller cable)+driver software (provided free)

  • What is the cost of implementing touch screens?

    Cost depends on size, quantity, and specifications. Please contact us for more details.

  • Is quick delivery possible with small quantity purchases?

    Standard touch screens are always in stock and prompt delivery is our policy. *Be advised, however, that in the unlikely event that stocks are low, delivery may be delayed.

  • How are touch screens mounted to LCD's?

    We can mount touch screens onto LCD's in our clean room. *This service is only available for DMC touch screens.

  • What is the operational life of a resistive touch screen?

    4-wire touch screens come with a ten-million-touch guarantee, and 5-wire touch screens come with a 35-million-touch guarantee.

  • Can I use gloves on a resistive touch screen?

    Yes, resistive touch screens respond to gloves.

  • Do resistive touch screens recognize multiple touched points simultaneously?

    Resistive multi-touch type can detect more than one touched point at the same time.

    4- and 5-wire resistive single-touch type can detect one touched point only. When two points are touched at the same time, the middle point is detected.

  • Please tell me how to mount a resistive touch screen.

    We provide mounting guidance.

  • What communication systems do DMC resistive touch controllers support?

    TSC-50/IC supports asynchronous serial (RS-232C) and USB communication (USB2.0 Full Speed). TSC-40/IC supports asynchronous serial (RS-232C) communication only.

  • Are there any resistive touch controllers that support PS/2?

    We're sorry, but DMC does not currently have controllers that support PS/2.

  • Can I use the resistive touch controller with a 3.3V power supply?

    Yes, please use TSC-50/IC. TSC-50/IC can be used in the power supply range of 3.00 - 5.25V.

  • Is there a circuit diagram for resistive touch controllers that I can refer to?

    Yes, please refer to the Touch Controller TSC-54 Series specification sheets.

  • Does DMC provide software specification sheets detailing commands?

    Software specifications are not available on the website; however, we are happy to provide them upon request. Please contact us.

  • How do resistive multi-touch type (MTR) touch screens differ from 4-wire and 5-wire resistive touch screens?

    When 2 points are touched at one time, 4- and 5-wire resistive touch screens detect the middle point between the two.

    MTR touch screens can detect two points when two different cells are touched.

    When two points are touched within a single cell, MTR touch screens detect the middle point between the two.

  • What is the MTR touch screen structure?

    DMC offers single-touch and multi-touch types. Please check "Search by Method & Type" in "PRODUCT" on the menu for details on the basic structure of each type.

  • What is the maximum size of the MTR series?

    Standard product lineup is up to 15 in. *Please consult with us if you need a MTR touch screen larger than 15 in.

  • What OS is supported by MTR series?

    Windows XP and 7 (operated with HID protocol). *For other OS, please consult with us.

  • Do you need driver software to operate the MTR series?

    The MTR series can be operated with Windows standard driver.

  • Is there a standard MTR series lineup?

    Yes, please see the MTR, MTR-G series product page.

    Analog Resistive Touchscreen
  • How long is the MTR series operational life?

    The MTR series applies the 4-wire system as the base and guarantees 10 million touches. They offer high durability and versatility.

  • Can I operate the MTR series with gloves?

    Yes, you can operate the MTR series with pens and gloves, which makes these suitable for FA and medical devices, and environments where it is hard to input data with bare hands.

  • Can I use the MTR series with a 3.3V power supply?

    No, the MTR series power supply needs to be between 4.75 and 5.25 V.

  • What communication systems do MTR series support?

    USB2.0. Please check the specifications for the standard product MTR, MTR-G series.

    Analog Resistive Touchscreen
  • What is the maximum size of the capacitive multi-touch type?

    Up to 32 in. wide.

  • How much of a gap distance is recommended between LCD and the capacitive touch screen?

    1mm or more. Keep the touch screen at least 1mm away from the LCD. See the recommended structure of touch screens mounted on LCD's.

  • What OS are supported?

    Windows XP, Vista, 7, CE*, Linux* *Please contact us for details.

  • Can the capacitive multi-touch type touch screen be used with gloves?

    Yes, DMC touch screens can be adjusted to the environment. We can make proposals for materials and glove thickness depending on customer needs and use environment.

  • Can you make the capacitive touch screen surface flat?

    Yes, we can make the surface flat by mounting a cover glass on the touch screen. Please check individual product pages for details.

  • Is there a limitation on the thickness of cover glass for capacitive touch screens?

    Yes. It depends on size of the touch screen. Please contact us for details.
