Display Products Group (DPG) of Hitachi Europe is introducing a new 19-in 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.
According to Hitachi, 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, such as a laptop with the user situated perpendicular to the TFT display. However, in medical diagnostic imaging systems 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 therefore 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. Steve Donohoe, technical manager for Hitachi Display Products Group, comments: "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. 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."
This superior performance also enables the 17inch, 19inch and 21.3inch displays to be used in a wide range of high-end, multi-viewer applications that require high optical performance. All models are suitable for use in public information displays, security surveillance, video monitoring and many high-end industrial applications. The TX48D21 features a long-lifetime CCFL backlighting unit.
The 19-in 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 16.7million colours to be displayed. The new display module has outline dimensions of 444mm (w) x 300mm (h) x 24.0mm (d) and weighs 2.9kg.
IPS-Pro technology provides viewing angles of 170 degrees in both horizontal and vertical planes without any significant reduction in contrast.
