Colour touch panel control on new digital cinema projectors

6 October 2004 Computer/Embedded Technology News & Events Security Services & Risk Management

Christie, a US supplier of digital cinema projectors, required a colour touch panel computer to help differentiate its cinema projectors from competitive products using traditional, monochromatic touch panels.

The company purchased a number of TPC-642 touch screen panels, locally available from ProMicro, for use in its new DCP-H and DCP-I lines of digital cinema projectors. The panel is used primarily in the set-up and operation of the projectors. The touch panel mounts to the mobile projector unit and connects to the projector head via Ethernet. An operator uses the touch panel to set parameters and operate the projector. The product is used in a variety of cinema applications, including theatres, post-production suites and multimedia theatrical productions.

This control application required that the controllers be rugged to withstand the environmental conditions for all cinema applications and run on a Windows CE platform. This project represents the first time that Christie has implemented colour touch screen panels in its digital cinema projectors, so simple control integration and product support were vital.

The compact TPC-642 allowed Christie to develop a solution quickly, speeding time to market, thanks to its standard Windows CE platform. This allowed the company to be the first projection manufacturer to implement a colour touch panel controller for digital cinema projection applications. Christie also capitalises on features such as Ethernet connectivity, secure login/password function and colour screen differentiation for ease-of-use and navigation. The control is robustly engineered to withstand temperatures from 0 to 45°C with a 142,5 mm touch screen rated to over 1 million activations.
