Customer Need: Replacement for existing panel
Background:
This customer is the design house for a global leader in self-service banking solutions and was looking to replace the existing CCFL display in an existing drive-through system. The new display had to include not only the panel and associated electronics but also enable a two-way video feed of the customer to the teller assisting with the transaction.
Challenges:
The teller camera needed to be embedded into the display and mounted onto an articulated arm. This was being viewed at a 45-degree angle, so IEE had to change the interface board to reverse the image. Additional support for various video delivery methods was also required.
The banking customers uses a pneumatic tube to complete their transactions, which causes additional vibration to the display and surrounding enclosure.
The drive-thru display required enhanced graphics and sunlight readability, and because it was outside, needed additional protection from temperature variations. The display also needed to fit within the existing housing.
Solutions:
Drive Thru Customer Display:
IEE sourced an open frame 6.4" LCD and replaced the CCFL backlighting system with one that delivered full-sunlight readability and added a heater to extend the operating temperature range. IEE added the camera interface electronics and packaged it all up with a custom back panel case that allowed for drop-in replacement into the existing drive-through equipment.
Indoor Teller Display:
IEE adjusted the interface of the inside display to flip, using a mirror to reflect the proper image back to the teller. Additional video support was added for NTSC and PAL/SECAM.
IEE continues to work with this client on their next generation design using a larger screen with touch capabilities.
