New Industrial LCD Panels Incorporate LED Backlight Systems with 100,000 Hour MTBF3
from Toshiba Mobile Display Co., Ltd.
Eight Panels in Sizes from 5.7-inch to 12.1-inch Increase Backlight Longevity
Toshiba Mobile Display Co., Ltd. (TMD) has announced the development of a new color active-matrix thin-film transistor (TFT) liquid crystal display (LCD) module lineup for industrial applications. The new display modules incorporate light-emitting diode (LED) backlighting systems offering an MTBF3 of 100,000 hours. The modules are designed to satisfy the requirements of a broad range of industrial applications, such as test and measurement equipment, medical equipment, mobile computing devices and more, utilizing the latest LED backlight technology. The series includes eight new LCD products, available in four screen sizes (5.7-inch, 8.4-inch, 10.4-inch, and 12.1-inch).
Compared to CCFL (cold-cathode fluorescent lamp) backlit displays, LED-backlit displays feature superior characteristics such as lower electromagnetic noise and lower power consumption, and offer a wider adjustable luminance range. The mercury-free1 LED-backlit displays also reduce environmental impact, in terms of both material content and energy consumption. Also, the new LED-backlit displays do not require the high-voltage and high-frequency circuits needed 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.
In 2008, ahead of all other competitors, TMD started volume production of a new series of industrial TFT LCD panels that incorporated an LED backlight system with 70,000 hours MTBF at ordinary room temperatures (25°C). This year, in a new development, TMD has succeeded in implementing LED backlight systems with an MTBF of 100,000 hours at ordinary room temperatures (25°C). The innovative backlight system achieves increased longevity through design optimization for heat dissipation and luminous efficiency. TMD expects to start volume production of the new LCD display lineup in the next half.
The successful development of a backlight system with an MTBF of 100,000 hours (approximately 11.4 years) fulfills typical product longevity requirements for industrial applications with frequent or continuous operation, thereby making the backlighting system essentially maintenance-free. The modules have been designed with a replaceable backlight structure to accommodate product longevity requirements encountered in some harsh industrial environments. Furthermore, TMD has added LED driver circuitry into the electrical interface for the displays, to simplify design-in time and cost.

1Mercury-Free: TMD defines “Mercury-Free” products as those containing no more than a maximum concentration value of 0.1 percent mercury (Hg) by weight in Homogeneous Materials2. This does not mean that Mercury-Free products are entirely free of mercury (Hg).
2Homogeneous Materials: TMD defines “Homogeneous Materials” to mean a material that cannot be mechanically disjointed into different materials. The term “homogeneous” is understood as “of uniform composition throughout,” so examples of “Homogeneous Materials” would be individual types of plastics, ceramics, glass, metals, alloys, paper, board, resins and coatings. TMD defines the term “mechanically disjointed” to mean that the materials can, in principle, be separated by mechanical actions such as unscrewing, cutting, crushing, grinding or abrasive processes.
3The MTBF (Mean Time between Failures) is not a guarantee or estimate of product life; it is a statistical value related to mean failure rates for a large number of products which may not accurately reflect actual operation. Actual operating life of the product may not resemble the MTBF.
