There are three new Winstar LCD-TFTs on Unisystem offer – WF39ESWASDNN0#, WF39ESWASDNG0#, and WF39ESWASDNT0#. Due to excellent parameters, these bar type displays can be applied in outdoor applications.
WF39ESWASDNN0#, WF39ESWASDNG0#, and WF39ESWASDNT0# are 3.9-inch LCD-TFTs of 480×128 px. The simplest version is WF39ESWASDNN0# which is just a display. The other models are beefed up with touch panels – capacitive in WF39ESWASDNG0# and resistive in WF39ESWASDNT0#. (You can notice these variations without even looking at the specification. Information on touch panel is represented in the part number – as the next-to-last sign (not including #): the letter N stands for a variant without touch panel, G is a model with capacitive touch panel, and T is equipped with resistive touch panel.)
The described models are high brightness solutions. The manufacturer declares the brightness of 1000 cd/m2 for WF39ESWASDNN0#, 800 cd/m2 for WF39ESWASDNG0#, and 700 cd/m2 for WF39ESWASDNT0#. (The lesser brightness values for WF39ESWASDNG0# and WF39ESWASDNT0# are because of the touch panel – it is an additional layer that blocks some part of the matrix backlight.) Due to high brightness, 800:1 contrast, and 80°/80°/80°/80° viewing angles, the content presented on these LCD-TFTs will be perfectly readable both in sunlight and darker spaces.
In the table, you can find the main parameters of WF39ESWASDNN0#, WF39ESWASDNG0#, and WF39ESWASDNT0#:
| model | WF39ESWASDNN0# | WF39ESWASDNG0# | WF39ESWASDNT0# |
| size | 3.9” | 3.9” | 3.9” |
| resolution | 480×128 px | 480×128 px | 480×128 px |
| brightness | 1000 cd/m2 | 800 cd/m2 | 700 cd/m2 |
| contrast | 800:1 | 800:1 | 800:1 |
| viewing angles | 80°/80°/80°/80° | 80°/80°/80°/80° | 80°/80°/80°/80° |
| interface | RGB | RGB | RGB |
| outline dimensions | 105.5 x 37.0 x 3.05 mm | 105.5 × 37.0 × 5.2 mm | 105.5 x 37.0 x 4.58 mm |
| touch panel | no | yes, capacitive | yes, resistive |
| operating temperature | -30~85 °C | -30~85 °C | -30~85 °C |
WF39ESWASDNN0#, WF39ESWASDNG0#, and WF39ESWASDNT0# operate in a wide temperature range. The manufacturer guarantees their failure-free operation between -30 and 85°C. Thanks to this feature, these products are perfect solution for outdoor applications such as vending machines, parking meters, ticket machines, charging stations, self-checkouts, etc.
