Technology trends
A leading picture-tube supplier, Samsung Display Devices Co. (Seoul, S. Korea), claims to have developed the first completely flat screen for its Dynaflat 17- and 19-in. color display tubes using proprietary glass-design, shadow-mask, and electron-gun technologies. The TCO-95-certified tubes provide an unprecedented 1600 ¥ 1200-pixel resolution, a 75-kHz horizontal frequency, a multilayer-film coating, and super pigment phosphors to achieve a 15% improvement in color reproduction. . . . Hewlett-Packard Co. (Palo Alto, CA), in conjunction with the Microsoft Corp. (Redmond, WA) upcoming Windows 98 operating system, has developed a prototype flatbed ScanJet scanner technology that uses the IEEE 1394 input/output standard for the seamless connectivity of imaging devices. . . . Epson America Inc. (Torrance, CA) is claiming that its PowerLite 7300 polysilicon LCD color portable projector is the industry`s first to deliver 1024 ¥ 768-pixel (XGA) resolution at 1200 ANSI lumens using a 120-W UHE lamp. . . . Motorola Inc. (Phoenix, AZ) has released its CMOS-based 300-dpi trilinear image-sensor/capture engine. It integrates a photosensor, timing control, analog-processing chain, 10-bit analog-to-digital conversion, and 12C serial-port programming control onto one chip. Claimed as the first CMOS image sensor with an on-chip digital signal-processing engine, the chip replaces as many as four parts typically required in CCD sensor systems and targets such applications as finger scanners, faxes, 2-D barcode readers, and multifunction peripherals.
