IEI Industrial 15" USB Interface Touch Screen Monitor. Typical monitors can only be used in environments that have temperatures in the0C~50C range. Extended IEI environmental testing
is performed to ensure the TDM series
continues to function properly over its entire service life in a wide working temperature range of -30C to +70C. After being tested in the -30C to +70C temperature range, the TDM series was found to maintain its original luminance.
The TDM-121GMS supports higher resolutions and smaller pixel pitches (0.24mm versus 0.24mm) to deliver great computer displays
With a luminance of 450 cd/m^2, the TDM series offer an improvement over the 250 to 300cd/m^2 luminance typically available with other15-inch TFT LCD modules. The high-brightness feature ensures the screen content is highly visible in all lighting conditions.
Typical small size monitors only support 130/110 (H/V) viewing angle,but IEI TDM series can support maximum of viewing angle up to 160/160(H/V). Wide viewing angles let you not lose the screen brightness and possibly a change of displayed colors, when you view the monitor from the side.
