Optir Touch - Resizable Infrared Optical Touch Screen
.
An Innovative DIY Design - Making your own touch screen size is as easy as playing kid’s building blocks.
.
You can connect IR transmitter and receiver segments to build touch screen from 5.15” x 5.15” to 70.4” x 70.4” with any aspect ratio. No more will you need to buy a new larger touch screen when upgrading your display to a larger size, just add new segments. As long as you can build your own IR screen from segments by mounting them onto a custom frame, you will no longer need to pay high freight charge for shipping an over-sized package, because you only need to purchase a small box of components. Current model is for USB interface and compatible with Windows 2000 & XP, Vista, and Intel Mac.

OPTIR Touch's Advantages:	Maximum clarity - no added overlay except protection glass if needed.
	Light touch - no pressure is needed, can be activated by finger, gloved hand or stylus.
	High durability - no moving parts involved.
	Do-it-yourself kit can be shipped at minimal cost comparing to shipping the finished large touch screen.
	Ability to resize the screen or increase the size by adding more components.

The IR touch screen is truly made of 100% solid state electronics. There is no moving part, and no mechanical function involved. It is assembled by one horizontal transmitter bar, one vertical transmitter bar, one horizontal receiver bar, and one vertical receiver bar. Each sensor bar is assembled by a number of segments of standard length to form the required active area. Each horizontal bar and vertical bar are connected by a corner PCB. A special corner PCB is used at right-lower corner for connecting to the controller board. The controller is USB interfaced to the computer, and the current driver supports Windows 2000 & XP.

Once the active area is determined, it will be very easy to calculate how many pieces of sensor component segments are needed. All the segments are very easy to connect and disconnect without needing any special tools.

The components need to be assembled onto a frame to complete the IR touch screen. This frame can be made by yourself, or KEYTEC can custom design it for you.

Currently available components are:

IRT-A	Transmitter 130.8 mm	IRCC	Connection corner	Example: 42” IR screen assembly needs:
IRR-A	Receiver 130.8 mm	IRSC	Corner to controller	Horizontal	2 IRT-A, 2 IRR-A, 2 IRT-B, 2 IRR-B.
IRT-B	Transmitter 348.8 mm	IR-CA	USB controller for size < 42”	Vertical	4 IRT-A, 4 IRR-A.
IRR-B	Receiver 348.8 mm	IR-CB	USB controller for 42” and larger	Plus 3 IRCC, 1 IRSC and 1 IR-CA

The assembled 42” touch screen of the above example has 1055.2 x 619.2 mm outside dimensions & 959.2 x 523.2 mm active area with 1050 x 760 touch resolution. Please email us for a quotation with your specified dimensions of active area, or you may download the following worksheet to make your own quotation. The example in this worksheet is for a 42" assembly, you can change the dimensions and recalculate for a new size.
