Projected capacitive touch panel joins TFT options
PCTP touch interfaces operate through a glass or other overlay, allowing the sensitive touch surface to be well protected from the surrounding environment.
This is the first time Varitronix is offering a transflective mono TFT unit, delivering better sunlight readability, and maintaining a greater contrast ratio in sunlight than the transmissive unit - allowing the backlight to be turned off in more applications.
However, for indoor use or where power consumption is not an issue, the transmissive equivalent features a higher contrast ratio and is offered as an alternative.
The new additions complement the existing 2.8in mono TFT displays in the range.
Boasting an exceptional contrast ratio between 600:1 and 1000:1, depending on viewing position, Varitronix mono TFT panels offer the same performance characteristics as full colour TFT in terms of viewing angles and operating temperatures.
With a transmission ratio in excess of 20% there is possibility to reduce the brightness or switch off the backlight to save power.
Mono TFT is also potentially much simpler to drive, requiring only small changes to the drive electronics for an existing STN solution.
In addition QVGA graphics allow a rich variety of information to be conveyed and a user friendly interface.
