New products unveiled at SID symposium
Display and touchscreen products and technologies took center stage at the 43rd Society for Information Display (SID) International Symposium, Seminar, and Exhibition held late in May in Boston.
TouchSense technology lets users perceive that on-screen buttons depress and release, just as physical buttons and switches do, according to manufacturer Immersion Corp.
Display and touchscreen products and technologies took center stage at the 43rd Society for Information Display (SID) International Symposium, Seminar, and Exhibition held late in May in Boston. Among the introductions were TouchSense technology for touchscreens from Immersion Corp., a high-definition compatible organic light-emitting diode (OLED) prototype from Samsung Electronics, and high-transparency touch panels for transmissive LCDs from Fujitsu Components America Inc. TouchSense technology for touchscreens reportedly supplies tactile cues not found in current touchscreens to provide a more intuitive, personal, and natural experience. According to manufacturer Immersion Corp ., instead of just feeling a hard, unresponsive touchscreen surface, users perceive that buttons depress and release, just as physical buttons and switches do. The realistic response is intended to restore the rich tactile information conveyed through physical controls. System designers can also synchronize the tactile sensations with sound and on-screen graphical images. Development kits for integrating the technology into are expected to be available by Q3 2005.
AM OLED prototype panel from Samsung Electronics offers a maximum screen brightness of 600 nits and an ultra-thin thickness of 3 cm.
Said to be the first single-sheet, 40-in. active matrix (AM) OLED for emissive flat panel applications, the high-definition-compatible OLED prototype from Samsung Electronics has a wide-screen pixel format of 1,280 x 800 (wide extended graphics array, WXGA) driven by an amorphous silicon (a-Si) active matrix backplane for faster video response times with low power consumption. The panel combines the traditional features of emissive OLED technology, including wide viewing angle, thin package size, no color filter, and no backlight, with the production infrastructure advantages of standard a-Si techniques. Until now, AM OLED prototypes have used more costly polysilicon approaches, which have limited production sizes.
High-transparency touch panels for transmissive LCDs from Fujitsu Components America Inc . enhance image contrast and clarity in high-ambient light applications. Additions to the company’s 4- and 7-wire resistive offerings, the panels feature 86% transmissivity and are intended for a variety of portable and stationary applications including tablet PCs and industrial instruments. A special index-matching coating on the panels’ glass and film layers lower reflectance losses. The panels feature consistently higher brightness with low-power LCDs and improved contrast.
The SID symposium gathered scientists, engineers, manufacturers, and users in the field of electronic information displays from around the world. SID is an international professional society devoted to advancing electronic-display technology, manufacturing, and applications.
