Irvine, Calif. — Toshiba America Electronic Components, Inc. (TAEC) has released five color active-matrix thin-film transistor (TFT) liquid crystal display (LCD) modules for industrial applications that incorporate long-life LED backlighting systems. Developed by Toshiba Matsushita Display Technology Co., Ltd. (TMD) the modules are designed to satisfy the requirements of a broad range of industrial applications such as test and measuring equipment, medical equipment, and portable handheld computing devices.
The series includes five new LCD products: 5.7-inch QVGA 320 x 240, 6.5-inch VGA 640 x 480, 8.4-inch SVGA 800 x 600, 8.4-inch 1024 x 768, and 10.4-inch XGA 1024 x 768. All five products feature replaceable LED-based backlighting systems. They also offer the capability to add a resistive touch panel as an option.
The LED-based backlighting systems provide an average backlight lifetime of 70,000 hours, or approximately 8 years continuous operation (to half-brightness of the initial luminance specification), which exceeds that of today's common TFT-LCDs for industrial applications using long-life cold cathode fluorescent lamp (CCFL) backlighting systems, according to TMD.
The modules have been designed with a replaceable backlight structure to accommodate the product longevity requirements and harsh-usage environments of industrial applications. In addition, the LED driver circuitry has been incorporated into the electrical interface for the displays to ease design.
Compared to CCFL backlit displays, LED-backlit displays are said to offer lighter weight, lower electrical noise, lower power consumption, and a wider adjustable luminance range. They also reduce the environmental impact in terms of material and energy consumption, since they are mercury-free and lower in power consumption. In addition, the LED-backlit displays do not require the high-voltage and high-frequency circuits required to control luminance in CCFL-backlit displays, thus enabling a higher level of flexibility in system design in terms of safety, electromagnetic interference (EMI) compensation, and system architecture.
These products will be exhibited by TMD at the 11th Embedded Systems Technology Expo & Conference (ESEC), booth #EAST35-15, Tokyo Big Sight, Tokyo, Japan, May 14-16, 2008, and by Toshiba America Electronic Components at the 2008 Society for Information Display (SID) International Symposium, booth #135, Los Angeles Convention Center, Los Angeles, Calif., May 20-22, 2008.
