Sound on Paper Olympus Optical Co. has announced in the Japanese press that it has co-developed a system to print voices and sounds on paper, and then to reproduce them. Important classes of organic EL devices with excellent transport properties and luminescence have been found. Organic materials can now be synthesized for specific purposes, and substantial improvements in colour and stability have been achieved. Today, the most efficient EL devices are of low molecular weight. Red, green and blue can be obtained at high brightness.
Emission is possible in sharp or broad bands, and devices are at the commercial stage.
If similar red devices may be made, the three films could be stacked to provide a small RBG pixel size, and maximum fill factor. Both IMS and SIMS are active in organic films. CTI will permit the integration of telephony, E-mail, and fax, and, within some companies, integrate telemarketing and telephone ordertaking with inventory, sales and accounting. Furthermore, open telephone systems such as PBXs will drive the market by supporting voice, fax, data, and, eventually, video, and by their seamless integration with company computing environments.
