Hitachi Europe Ltd, Display Products Group (DPG) has announced the introduction of a new 19inch 1.7MegaPixel WSXGA+ TFT display module. The new TX48D21VM0CAA display implements the latest evolution of Hitachi's In-Plane-Switching technology, IPS-Pro, which provides a stable colour image from any viewing angle, excellent colour saturation and a very high contrast ratio.

Demand for wide viewing angle and wide field of vision displays has increased in high performance monitoring equipment. Medical imaging applications such as ultrasonic based diagnostic and computed tomography (CT) scanning systems require highly consistent optical performance and accurate image reproduction. Contrast and colour characteristics must be maintained over a wide range of viewing angles/positions. When viewed from an acute angle, a conventional TFT display will exhibit a loss of brightness and display image colours become inverted. In certain applications this performance limitation is not critical; a laptop pc where the user is situated perpendicular to the TFT display. In medical diagnostic imaging systems however the image viewed by one doctor or consultant could be different to the representation seen by a second viewing consultant in an alternative viewing position. Hitachi's IPS-Pro TFT technology overcomes the limitations of conventional TFT display technology.

The new TX48D21VM0CAA display modules joins Hitachi's existing 17inch SXGA and 21.3inch UXGA IPS-Pro TFT displays that are targeted at high performance medical applications. "Customers in professional markets can benefit from the high contrast and wide viewing angles achieved by IPS-Pro technology. For applications where absolute image quality is paramount these displays deliver unparalleled performance," says Steve Donohoe, Technical Manager for Hitachi Display Products Group "The new TX48D21 display offers excellent colour saturation with a very high contrast ratio. The black level of the new display combined with improved transmittance helps to provide a contrast ratio of 900:1."

The superior performance of IPS-Pro technology also enables the 17inch, 19inch and 21.3inch displays to be used in a wide range of high-end, multi-viewer applications which demand high optical performance. All models are ideally suited for use in public information displays, security surveillance, video monitoring and many other high end industrial applications.

The 19inch WSXGA+ TX48D21VM0CAA features a resolution of 1680 x 1050 pixels, a contrast ratio of 900:1 and brightness of 300cd/m². The LVDS input signal interface enables up to 16.7M colours to be displayed. The new display module has outline dimensions of 444mm (w) x 300mm (h) x 24.0mm (d) and weighs in at 2900g.

The IPS-Pro technology used in the TX48D21 display ensures viewing angles of 170 degrees in both horizontal and vertical planes, without significant reduction in contrast. The TX48D21 features a long-lifetime CCFL backlighting unit.

The new TX48D21VM0CAA display is sampling now and scheduled for mass production in Q1/2009. For more information, please visit http://www.hitachi-displays-eu.com or call +44(0)1628 585 000.
