Drone Monitor – 21.5″ TFT Display Case Study
"We need a high brightness display for daylight viewing"
We received a requirement for a 17″ to 21.5″ TFT display which could be used as a monitor for drone surveillance. The monitor had to be mounted in a Peli-Case that would be used outdoors, therefore the display needed to be high brightness, daylight readable, with a composite video connection. A forthcoming exhibition created a 5 week deadline for the customer and requirement for Relec to deliver the first 2 prototypes on time!
19.0 PCAP Touch Panel
Construction: Glass/Film/Film (GFF)
Number of fingers: 10
Cover lens: up to 10mm
Signal to Noise ratio: 32V
Working with one of our specialist suppliers, FutureLabs, we designed a semi-custom 21.5″ display that would be fit for purpose based on an already existing standard product in the following areas
- Increased brightness from 300 cd/m2 to 1000 cd/m2
- Applied optical bonding into the air gap to make it daylight readable
- Fitted a 3mm cover glass with anti-reflective polariser to improve ruggedness and reduce reflection
- Supplied an AD interface card with composite video input and a set of custom cables
Relec delivered the 2 prototypes within 4 weeks as promised This was achieved with all of the above modifications as well as custom tuning the firmware for the AD interface card.
