Linfinity Introduces Digital Dimming Inverters for Large LCD Displays.GARDEN GROVE Garden Grove, city (1990 pop. 143,050), Orange co., S Calif., a suburb of Long Beach and Los Angeles, on the Santa Ana River; founded 1877, inc. 1956. Many of its residents work in nearby aerospace and defense installations, and there is light manufacturing. , Calif.--(BUSINESS WIRE)--Oct. 7, 1998--Linfinity Microelectronics Inc., a subsidiary of Symmetricom, Inc. (Nasdaq:SYMM SYMM Synchronized Multimedia (W3C Working Group) ), has introduced a quad-lamp version of its RangeMAX(TM) digital dimming backlight back·light n.

If the input is true, the output is false, and vice versa. An inverter performs the Boolean logic NOT operation. (2) A circuit that converts DC current into AC current. Contrast with rectifier. modules targeted at larger 18" LCD displays. In contrast to 2:1, 3:1 and 5:1 dimming ranges typically provided by conventional analog inverters, Linfinity's new LXM1641-02 RangeMAX inverter modules achieve a usable dimming range in excess of 100:1 by using the company's innovative direct drive digital dimming circuitry. Smooth, flicker-free dimming through a full 0-100% brightness control is enhanced further by the module's ability to deliver readable displays at lowest light levels. Critical for many large-screen applications is the LXM1641's low power consumption and reduced heat generation, the company said. "Linfinity is currently positioning its market focus and new product development efforts on products that deliver light, sound, and power management to desktop and mobile computing Using a computing device while in transit. Mobile computing implies wireless transmission, but wireless transmission does not necessarily imply mobile computing. Fixed wireless applications use satellites, radio systems and lasers to transmit between permanent objects such as buildings platforms," commented James J. Peterson, President and Chief Operating Officer Chief Operating Officer (COO) The officer of a firm responsible for day-to-day management, usually the president or an executive vice-president. of Linfinity Microelectronics. "This new backlight product, the latest in the RangeMAX family of backlight inverter modules, is designed for high-end displays found in next-generation PC and desktop computing platforms." "Now large-panel LCD designers have quad-lamp RangeMAX inverters available with all the advantages direct drive digital dimming provides," said Roger Holliday, Vice President of Marketing at Linfinity. "Our patent-pending RangeMAX technology provides extended dimming that saves power at all brightness levels." "Our inverters also take advantage of Linfinity's capabilities in designing and manufacturing high volume proprietary integrated circuits Integrated circuits Miniature electronic circuits produced within and upon a single semiconductor crystal, usually silicon. Integrated circuits range in complexity from simple logic circuits and amplifiers, about 1/20 in. (1. as well as our long experience in high-rel products for aerospace applications. As a result, Linfinity can create commercial inverters that provide outstanding functionality, reliability and lamp life at low cost," continued Mr. Holliday. RangeMAX inverters for multiple lamp applications include a failsafe feature that maintains display operation in the event that a single lamp fails. It allows continued operation from the remaining lamps at a near-normal brightness level until it is convenient to replace the failed lamp. The new RangeMAX LXM1641-02 quad lamp modules for 18"cold cathode A cathode in a gas-filled electron tube that is not heated by a filament in order to excite the electrons and cause current flow. The voltage potential within the tube is sufficient to ionize the gas in the tube and cause current flow. fluorescent lamp (CCFL (Cold Cathode Fluorescent Lamp) Same as CCFT. ) display applications are available for immediate sampling and delivery. In quantities of 1,000, the modules are priced at $59.00. Symmetricom, Inc. (Nasdaq:SYMM) conducts its business through two separate operating units. Telecom Solutions provides advanced network synchronization products that play a critical role in the operation and quality of service of sophisticated telecommunications networks. Telecom Solutions' customers include network operators and network infrastructure providers.
