TFT LCD modules
Toshiba Electronics Europe is offering a family of TFT LCD modules from Toshiba Matsushita Display Technology (TMD) for industrial applications.
The colour active-matrix industrial thin-film transistor (TFT) LCD product line-up incorporates 70,000-hour-life LED backlighting systems.
The modules are designed to satisfy the requirements of a range of industrial applications including test and measurement equipment, medical devices, portable handheld computing products and panel computers.
Toshiba's new series comprises five LCD products, available in screen sizes of 5.7in, 6.5in, 8.4in, and 10.4in and all featuring a luminance rating of 400cd/m2 with contrast ratios at 400:1.
TMD will add 12.1in versions with SVGA and XGA resolutions to the line-up in the first quarter of 2009.
The 5.7in LTA057A343F is supplied in a QVGA (320 x 240) format and the 6.5in LTA065B0D2F in a VGA (640 x 480) format.
The 8.4in LTA084C271F and LT084AC37000 are available in SVGA (800 x 600) and XGA (1024 x 768) formats respectively, while the 10.4in LT104AC36100 provides an XGA (1024 x 768) resolution.
All of the products have replaceable, long-life, LED-based backlighting systems, and are designed so that a resistive touch panel can be added as an option.
Providing an average backlight lifetime of 70,000 hours (to half-brightness of the initial luminance specification), the backlighting systems employed in the new displays exceed the lifetime ratings for industrial LCDs based on long-life cold cathode fluorescent lamp (CCFL) backlighting systems.
The modules have been designed with a replaceable backlight structure to accommodate product longevity requirements and the harsh environments of many industrial applications.
TMD has integrated the LED driver circuitry into the electrical interface for the displays, allowing customers to reduce design-in time and costs.
Compared to CCFL backlit displays, LED-backlit displays feature superior characteristics in terms of weight, electrical noise and power consumption.
They also offer a wider adjustable luminance range.
As well as the lower power consumption, LED-backlit displays also reduce environmental impact since they are mercury-free.
Finally, the new LED-backlit displays do not require the high-voltage and high-frequency circuits required to control luminance in CCFL-backlit displays.
This enables a higher level of flexibility in system design in terms of safety, electro-magnetic interference (EMI) compensation, and system architecture.
