/> TFT LCD display modules have become widely and extensively used in many electronics products and systems that require a high quality graphical user interface. Certain environmental conditions such as bright ambient light and outdoor conditions can present challenges for conventional TFT displays. When a display is used in a high ambient light environment, if the amount of ambient light reflected by the display is close to or exceeds the amount of light emitted by the display, the display image can become unreadable and ‘washed out’. In this situation contrast loss can be close to 100% as the luminance of the display is exceeded. A TFT display featuring an optically bonded glass substrate and surface treatment techniques can reduce reflections to less than 0.2% by scattering and absorbing ambient light. These additional features will ensure that display readability can be notably improved.

Mark Stephenson, Product Marketing Manager, commented, “Many TFT displays are used in bright ambient light or outdoor conditions which present difficulties when trying to ensure that the display provides optimum readability. The use of glass optical bonding technology coupled with an enhanced anti-reflection or anti-glare surface finishes can significantly improve the optical performance of the display. Further benefits include making the display module more rugged and able to provide enhanced shock and vibration performance. Display durability is also improved with increased impact and scratch resistance and reduced fluid and foreign particle ingress.”

Developments in optical glass bonding techniques has now enabled Hitachi TFT LCD display modules to offer excellent readability in demanding ambient light conditions. This enhances the provision of TFT display solutions across a wider range of environments and applications. Optical bonding technology has been successfully implemented on TFT displays used in challenging environments such as aerospace, marine, automotive, medical and industrial. It is also being viewed as a key display enhancement technology for facilitating the development of emerging products and designs.
