Abstract

The known CRT touch display technology is modified and made suitable for automatic teller machine (ATM) "through-the-wall" use by providing a laminated touch panel consisting of specular, privacy, and contrast filters. The technique for mounting the laminated touch panel provides environmental sealing, circuit connection, and transducer pre-biasing. Fig. 1 shows a cross-section of the present embodiment of a laminated touch panel assembly. It is seen that a laminated face plate consisting of specular filter 1, lattice filter 2, and contrast filter 3, together with transducer 4 and its flat foil conductive circuit 5, are clamped together by front frame 6 and back frame 7 under controlled pressure provided by gasket 8. The laminated face plate is rectangular and curved to match the face of the CRT.
