Ambient Light Control / ALC
The ALC function enables ambient light-dependent brightness adjustment of the display backlight. Thanks to this feature, optimal readability of the display can be achieved under all environmental brightness conditions. In addition, the power consumption of the units is reduced to a minimum, thus increasing the service life of the monitors. Our Ambient Light Control system reacts only to visible light and can therefore also correctly read daylight, which has an extremely high (invisible) IR component. The ALC function can be configured individually to suit the respective application.
Display Performance Monitoring / DPM
The Display Performance Monitoring (DPM) function continuously monitors the correct operation of the display via a panel sensor. Critical errors, such as a faulty backlight system, a defective power supply unit or a malfunctioning TCON board, can thus be detected quickly and precisely. For this purpose, together with a sensor, a small flashing square is displayed on the screen (size depends on the resolution and diagonal of the display, typically 4x4 pixels), which is positioned inconspicuously in a corner of the screen. The sensor checks the regular flashing of the white square and reacts in case of malfunctions or errors. The system is then either restarted directly and/or an error message is issued.
Automatic Backlight Stabilization / ABS
The brightness of a backlight system naturally decreases continuously over the operating time. To keep the brightness constant over a longer period of time, our Automatic Backlight Stabilization (ABS) function can be integrated.
To create a sufficient control range, the maximum backlight brightness is first reduced slightly (e.g. to 80%).
A brightness sensor continuously measures the backlight brightness and the backlight power is readjusted accordingly. Thus, the display keeps its brightness constant until the control limit is reached. Only after that period the backlight becomes darker. In addition, the automatic backlight stabilization enables the output of an error message as soon as the backlight has reached the end of its service life.
