TOSHIBA AMERICA ELECTRONIC COMPONENTS TO SHOWCASE ADVANCED LCD AND OLED PRODUCTS AND TECHNOLOGIES AT SID 2007
Innovative Display Products and Prototypes for Mobile Phones and Portable Electronics, Automotive, Mobile Computing, and Industrial Markets to be Featured
IRVINE, Calif., May 22, 2007 — Toshiba America Electronic Components, Inc. (TAEC)* will demonstrate an extensive array of next-generation displays and display technologies developed by Toshiba Matsushita Display Technology Co., Ltd. (TMD)** for mobile phone and portable electronics, automotive, mobile computing, and industrial markets in booth #1149 at the 2007 Society for Information Display (SID) International Symposium, Seminar & Exhibition in Long Beach, CA, May 22 to 24, 2007.

Featured technologies in TAEC’s booth this year include optically compensated bend (OCB), low temperature poly-silicon (LTPS), System-on-Glass (SOG), and Organic Light-Emitting Diode (OLED) displays.
OCB Technology
  • TMD’s latest 32-inch OCB LTPS thin-film transistor (TFT) active-matrix LCD features 1,000,000:1 contrast ratio, an ultra-fast 2.0ms Motion Picture Response Time (MPRT) and ultra-wide viewing angles (to 176 degrees) in all directions, surpassing cathode ray tube (CRT) front-of-screen performance1. For comparison, the 32-inch OCB panel will be shown adjacent to a 32-inch CRT TV.
  • A 12.1-inch SVGA (800 x 600) OCB LCD that also features 1,000,000:1 contrast ratio, ultra-fast 2.0ms response time, and ultra-wide 176-degree viewing angles in all directions will be displayed side-by-side with a conventional twisted nematic (TN) mode LCD to show the improvement in motion picture legibility that is possible with OCB technology, as well as the ultra-wide viewing angles and fast response time that enable OCB displays to provide image quality superior to conventional TN mode LCDs2.
  • Two 9.0-inch WVGA (800 x 480) LCD displays, one in OCB mode and the other in conventional TN mode, will be shown operating at -20oC to demonstrate the benefits of OCB’s fast response time, even at the extreme temperatures that can be encountered in automotive video and navigation applications.
  • A 4.3-inch prototype WQVGA (480 x 272) display combines OCB liquid crystal technology, which offers both a wide viewing angle and a fast response time, and transflective technology, which assures high viewability both indoors and outdoors. The development of this combination is a first in the LCD industry. The module features very high brightness for a transflective module of 400 candelas per sq. meter (cd/m2), with 2.4ms response time in reflective mode and 5.3ms response time in transmissive mode. The innovative panel is targeted for use in portable media players and will be displayed in the Mobile section of the booth.
  • A 4.13-inch prototype high-resolution transmissive WVGA (800 x 480) OCB module will also be shown in the Mobile section. Like the ultra-high contrast 32- and 12.1-inch modules noted above, this LTPS module features 1,000,000:1 contrast ratio, 2.0ms ultra-fast MPRT response time and 176-degree ultra-wide viewing angles in all directions. The improvement in contrast ratio was achieved by optimizing the backlight performance relative to the display image, to obtain deeper blacks, thus increasing contrast and visual depth perception.
System-on-Glass Technology
To demonstrate the potential that TMD’s LTPS SOG technology offers for integration of additional functions and circuitry, two prototypes will be shown that integrate input functionality into the substrate glass. This enables brighter, more vivid images by eliminating an external touch panel, which typically degrades optical performance. In addition, the reduction in number of components and connections enhances reliability and contributes to a thinner, lighter weight design.
  • A switchable-mode, finger-shadow-sensing or light-pen-sensing input 2.8-inch WQVGA (240 X 400) LCD panel will be featured in the booth. It operates across a significantly increased range of ambient light intensities compared to previous generation SOG input displays. Booth visitors will be encouraged to test the display, which supports input to the LCD screen by directly touching an icon or button on the LCD screen with a finger, or by directly writing onto the LCD screen with a light pen. The finger-shadow-sensing technology could be used in a touch panel application, while the light-pen-sensing technology could provide functionality similar to today’s digitizer applications.
  • A second 2.8-inch WQVGA (240 x 400) finger-sensing input display, which can sense input without external devices, will be the subject of a conference presentation and will be shown in the booth. This input display operates in any ambient lighting condition by recognizing a finger’s reflection from an internal backlight when in dark lighting conditions, and recognizes a finger’s shadow from ambient lighting when in outdoor lighting conditions. Advanced performance compared to earlier input display prototypes was achieved through improved high-speed driving circuitry, increased sensitivity of the photo sensors embedded in the glass substrate, and more sophisticated signal processing.
  • In addition, three highly integrated mobile phone displays, including 2.2- and 2.4-inch QVGA (240 x 320) modules and a 2.6-inch WQVGA (240 x 400) prototype module will be exhibited. They each achieve improved durability and reliability through integration of analog circuits (D-A converter and amplifier), driving and power supply circuits, and an integrated control circuit, thus reducing external components, simplifying the assembly process, and contributing to reduced weight.
OLED Technology
TMD is demonstrating the excellent color reproduction and true black performance of its new top-emission OLED technology with a 2.8-inch WQVGA (240 x 400) active matrix module with an ultra-fast response time of less than 1.0msec, high brightness of 400cd/m2 and color gamut greater than 90 percent. Top-emission OLEDs emit light away from the substrate to achieve higher brightness with lower power consumption, compared to bottom-emission OLEDs, thereby extending the life of the panel. An OLED panel reproduces images from light emitted by the fine organic electroluminescent film formed on the glass substrate, thus it can provide high-contrast, clear images with ultra-fast response time for remarkable moving picture performance. In addition, the OLED panel features an ultra-wide viewing angle, and is thinner and lighter than an LCD, since no backlighting system is required.
New Displays
In addition to the technology demonstrations noted above, a diverse line-up of commercially available displays and prototypes for mobile phones and portable electronics, mobile computing, industrial and automotive applications will also be featured.
Mobile Phones/Portable Electronics: TMD’s broad line of displays for mobile phones, handheld GPS, portable media players and more will be represented by 2.4- and 2.6-inch QVGA (240 x 320), 2.8-inch wide WQVGA (240 x 400), and 3.0-inch WVGA (800 x 480) LTPS TFT LCD modules. The 2.4-, 2.6- and 2.8-inch prototype modules incorporate thin glass and are only 0.99mm thick, including the backlight, to enable even thinner and lighter weight mobile phones. The high-resolution 3.0-inch WVGA display features five times the number of pixels as available in the QVGA format, and a pixel density of 313 pixels per inch to support greater information content and superior image quality for web and mapping applications.
Automotive: Displays for automotive entertainment and navigation applications will be featured, including a 15-inch class ultra-wide 1280 x 390 concept display for instrument clusters that can switch among multiple views as required, such as speedometer and tachometer, navigation guides, meters and gauges, and from rear-view camera systems. In addition, representative technology prototypes from TMD’s extensive product line-up of 5.8- to 9.0-inch modules for both automotive entertainment and navigation applications will be showcased. One noteworthy prototype is an 8.0-inch WVGA (800x480) color active-matrix automotive display for navigation applications that uses a new LED backlight, instead of the conventional cold cathode fluorescent lamp (CCFL) backlight system, to achieve color gamut performance of approximately 90 percent. The high-resolution WVGA format provides excellent image quality for video and/or mapping applications, while the LED backlight enables quick start-up at low temperatures typically required in automotive applications. In addition to the 8.0-inch WVGA display, a 7.0-inch WVGA (800 x 480) display featuring a wide viewing angle, "normally black" display mode and LED backlight system will also be shown.
Mobile Computing: TMD’s recently expanded (March 20, 2007) series of notebook PC LCD displays feature a thin, lightweight structure achieved through poly-silicon technology, glass thinning and LED backlighting. Combining 0.3mm or thinner glass and LED backlighting in LTPS-based TFT LCD modules enables and enhances even higher portability in the mobile PC segment of the marketplace. An 8.9-inch WXGA (1280 x 768) transflective mobile PC module with 0.3mm glass provides excellent image quality in a variety of ambient lighting conditions. In addition, a 12.1-inch module with 0.2mm glass, and a 13.3-inch module with 0.3mm glass, both in wide-format WXGA (1280 x 800) resolution, will represent TMD’s diverse line-up of ultra-lightweight transmissive TFT LCD panels. Mobile PCs from leading manufacturers demonstrate various TMD display modules in commercially available notebook applications, including a 14.1-inch SXGA+ (1400 x 1050) notebook, as well as wide-format models featuring the 8.9-inch, 12.1-inch and 13.3-inch WXGA displays described above.
Industrial: Featured LCD modules for the industrial market range from a 3.5-inch QVGA (320 x 240) display with replaceable LED backlight to a very high brightness, 1000cd/m2, 12.1-inch SVGA (800 x 600) module with improved viewability for vending machines, ticket dispensers, or other equipment installed outdoors. Additional new industrial-use modules at SID include a 5.7-inch QVGA (320 x 240) module with enhanced resolution and replaceable LED backlight for use in measuring instruments and handheld computing devices; high-brightness 10.4-inch and lightweight 8.4-inch modules to expand TMD’s popular SVGA line; and a new 7.0-inch module to expand TMD’s WVGA (800 x 480) wide-screen lineup. Each of the new LCD modules has been designed so that it could be equipped with an optional resistive touch panel. (See separate announcement dated May 9, 2007.) Additional modules on display from TMD’s broad industrial line include an 8.5-inch WVGA (800 x 400) module ideally suited for use in multi-function printers, and a 5.0-inch WQVGA (400 x 234) AV panel with analog video interface and LED backlighting.
