Frequently Asked Questions

Just a few of the Frequently Asked Questions about touch screens and displays.

Q

What operating systems do your touch screens work with?

A

Some touch screens are HID compliant and no drivers are needed – where drivers are needed they are commonly available for Windows XP, 7, and 8. Mac OSX and Linux drivers are also available. Most drivers are bundled free of charge but there are some exceptions with Mac OSX and UNIX drivers.

Q

What is the difference in LCD technology?

A

There are a few panel technologies to choose from. Black Cat likes to offer the best viewing experience by offering IPS, PVA or MVA but sometimes budget is a consideration and mass market TN is the panel of choice. Find out more by reading our white paper.

Q

Are all your screens LED?

A

This relates to the backlight of the panel it has many benefits over the older CCFL backlight which is gradually being phased out. However Black Cat would not dismiss it just yet.

Q

Can I use the mouse with a touch screen?

A

Yes the mouse works alongside the touch which is useful while developing but you consider losing the mouse when the application is ready. Turning off the mouse cursor prevents user intervention and hides what is behind.

Q

Is the touch screen plug and play?

A

With the introduction of Windows 7/8 and Mac OSX the integration of touch is becoming common place. The often works as an HID device and there is little to do. On occasions where this does not there is usually a touch screen driver.

Q

What can I use to clean the touch screen?

A

Touch screens generally have a very high chemical resistance. However we recommend Alcohol based screen wipes or if you must spray glass cleaner applied to a cloth but not directly on to the screen. Saturating the screen is not good for the electronics.

Q

Can you seal touch screens to IP65?

A

Resistive and Capacitive technologies can be sealed to IP65 usually specified as on the front only. Extreme care needs to taken when making the seal especially when they are used on food packing lines.

Q

What is true Multi-Touch?

A

True multi-touch seems to refer to anything over two points on the screen being touched at the same time.  Windows 7/8 supports common gestures where dual touch is enough. There is also support in Mac OSX via a separate application.  If you require more than dual touch a specific application can be developed using an API.

Q

What do I need to connect a touch screen to a computer?

A

Usually it is just a video cable and an interface lead for the touch screen. The display (unless it is USB) will need its own power. The video/display lead will be VGA, DVI, HDMI or Display Port. The touch interface lead will be USB or Serial.

Q

How far away can I locate the touch screen from the computer?

A

There are restrictions with video and touch. We recommend a maximum of 3 metres but this can further if use high spec cables or video/USB extenders.
