Flat screen gives wide angle view

The industrial siemens flatpanel display technology (i-sft) range has been extended with the addition of a 15in version which, in common with other models in the range, is well suited for use in harsh industrial environments.

The new 15in version is housed in a rugged all-metal casing measuring 331x258x18mm. It is supplied with an integral inverter as a co-ordinated system which does away with he normally complex fine tuning between inverter and backlight. Maximum luminance is 500 candela/m2, a contrast ratio of 200:1 and the guarantee of the optical properties across an operating temperature range of -10 to +70oC. Screen life is quoted as 35,000 operating hours, mean time to half brightness.

To achieve the required level of luminance, Siemens uses two longlife cold cathode fluorescent lamps coupled to a complex optical system to achieve an even distribution of light and a wide viewing angle. The company claims that viewing is possible as much as 70o right or left of the perpendicular axis.
