Display Technology adds proximity sensor which detects a frozen screen

Distributor Display Technology has added the IF444 sensor manufactured by Distec. The IF444 sensor can detect a frozen screen and alert users to avoid downtime.

The motion sensor checks a few pixels of the active screen area for a blinking pattern. If the image signal is missing or the background lighting is defective, a warning signal is passed on to a PC or single board computer by Distec’s Prisma card, Distec’s Artista TFT controller or the connectivity board, the IF445.

The IF444 sensor can be integrated with a PC, single board computer or used in conjunction with a TFT controller such as Distec’s Prisma cards. In the event of a fault, an alert is sent. This can be a digital and visual signal and there is also an audible option available.

The IF444 frozen screen sensor operates with Windows or Linux operating systems. It is mounted by adhering to a corner of the active display surface. In existing systems, it can be attached mechanically by the equipment user or the IF444 sensor option can be specified on a TFT module at the time of purchase.

The new sensor is a cost-effective solution to ensure continuity operation.
