RMTS resistive multi-touch screens: new resistive multi-touch solution overcomes
PCAP limitations in the military market Midas Displays, a leading one stop supplier of industrial flat panel display, touch screen solutions interconnect and driver solutions, talk about some of the display products that can be used in, and why they can be good for, the military and defence industry

10-point multi-touch for industrial environments eliminates EMI limitations
idas Displays offer products from Mildex Optical Inc., a worldwide leader in resistive touch screen technology. They
offer a 10-point multi-touch solution based upon widely approved AMR resistive touch technology. The AMR Technology developed for dedicated applications where the Projective Capacitive Touch Screen fails on reliably managing gloved input,
and where “gloved hands” or stylus interface are essential.
surface contamination with conductive liquids and harsh EMI environments. Equipped with superior optical and functional characteristics their RMTS is the number one choice for demanding industrial, medical and military applications, where secure true multi-touch functionality is required in rugged and harsh environments,
The utilisation ranges from MIL-notebooks to industrial HMIs and all applications, where isotonic liquids on the surface do not allow any capacitive solutions. With EMI micro mesh integrated stack-up a complete Faraday Cage solution including touch signals can be achieved. Mildex Optical is also the number one developer and in house manufacturer for Sunlight Readable Touch Screens with integrated circular polariser. Mildex makes a clear difference in any kind of outdoor lighting conditions, with their patented state-of-the-art EclipsTouch/Sunlight
Readable Resistive Touch Screens. Mildex optimises and customises the optical characteristics of the touch screen by enhancing the polarised light transmission, colour, saturation and contrast, while reducing the natural reflection, resulting in extended battery power and the LCD display life. Available in their Glass Film Glass technology. EclipsTouch Touch Screens from Mildex are ideal for applications such as: avionics, marine, military, GPS, rugged notebooks and tablets. The RMTS resistive multi-touch screen comes as 7”-15” standard size range and full customisable option available of 7”-19”.

Further optical enhancement possibilities I
Optical bonding and increased ruggedness
n general, many users of display technologies need additional enhancements to ‘standard’ displays and in particular TFT LCD’s. Many applications today require enhanced performance, not just military and avionics, with sunlight readability and public usage applications continuing to grow in numbers and popularity. There are many challenges in achieving a working outdoor display solution including: • Sunlight readability• Impact protection • Scratch resistant • UV resistance and UV protection • Extended temperature range • Extreme weather resistant
Sunlight Readability has typically been
addressed with increasing backlight output but that is a losing battle, in truth, contrast enhancement is the only way to achieve sunlight readability in a sustainable and
efficient way, managing losses instead of creating them.
Midas Displays can provide optical bonding and cover glass, and polarisation enhancement which are the only true ways to overcome many of these issues. There are many benefits to having a display that provides sunlight readability without backlight modification. It can reduce reflectance and refraction, it increases contrast ratio in high ambient light environment and eliminates the “wash-out” effect. It also improves clarity and reduces “sparkles”, allows more backlight to go through and there is no increase on power consumption or generated heat. As an added benefit, optical bonding also
provides increased ruggedness and impact protection even vandal resistance and better durability. This absorbs impact (shock protection), it provides better adhesion, and prevents water condensation and other
contamination. It also eliminates “green house” effect, has UV protection, no pooling and allows “over-frame” bezel design. The displays also reduce parallax error which makes the product greener and requires only one AR on top for optimum optical performance.
