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#:
|resolution||480×128 px||480×128 px||480×128 px|
|brightness||1000 cd/m2||800 cd/m2||700 cd/m2|
|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.
