25 ± 2˚C
Room temperature

This is the temperature where LCD luminance output is the same as specified in tech specs. In most systems this is impossible to reach, unless an active cooling system (HVAC) is used (e.g. imotion G7 technology).

10 – 40˚C
Normal operation temperature

Normal LCD operating temperature range presents minimal drop in brightness performance output. Within this temperature range heat or cold doesn’t affect health of the LCD screens.

0 – 50˚C
Warranted operation temperature

Warranted operation range is the maximal range of inner enclosure temperatures for decent brightness performance output. All imotion systems automatically shutdown before this range is exceeded.

Find out why is thermal management becoming increasingly important?

LCD luminance output

LCD panels uses LED backlights to operate. Luminance output of LED lights depends heavily on LCD operating temperature. Lower the temperature higher the brightness performance output.

Ambient temperature (˚C) effect on luminance output coefficient

Benefits

Utilizes fans for cooling airflow into the signage enclosure.

Efficient and cost-efficient cooling method.

Fans are speed-regulated and respond to enclosure temperature

Limitations

Enclosure temperature is always limited by the level of ambient temperature.

Benefits

Closed airflow loop.

Stable enclosure temp. = best visual performance.

Extended expected LCD lifetime (+30%).

Can work in most demanding outdoor environments.

Limitations

Higher initial cost

Conclusion

Cold and heat affects LCD screens. Propper thermal management lowers the impact of environment temperature to its minimum and ensures high image quality, low power consumption and slow component degradation.
