Unlike our competitors, the Noritake GT-1P module (GT800X480A-1303P) has a metallized projective capacitive touch (MPCT) panel that produces an extremely high signal-to-noise ratio, allowing it to perform exceptionally well in a variety of different environments with gloves, glass, acrylic cover plates, or when wet.
Below, we will compare the touchscreen capabilities of the Noritake GT-1P module and a competitor module.
Both the Noritake GT-1P module and competitor module accept digital video interface (DVI) through an HDMI (High-Definition Multimedia Interface) cable and touch via USB.
Below, we will examine the touchscreen performance of the Noritake GT-1P module and a competitor module under differing conditions. First, we will test them with no covering element. After that, we will test the modules using a glass plate overlay, then under a 2-millimeter thick acrylic plate overlay and finally under a 5-millimeter thick acrylic plate overlay.
The touch sensitivity (threshold) level for the Noritake GT-1P module can be adjusted between a range of 0 and 255 while the competitor module cannot be adjusted at all. For these tests, the Noritake GT-1P module was set with a touch threshold of 48.
For this test, we drew a single “S” on each module’s touch screen and observed how they performed. To start, we conducted a default test without any cover overlay.
The first test was performed without any cover overlay and the test consisted of drawing a single “S” on each of the module’s touchscreen.
When using the competitor module, we need to have a finger on one of the mounting screws to ground the device so it works correctly.
Next, we overlaid a 1.6-millimeter thick glass plate onto each module’s touchscreen. Thin rubber mounting tape was attached to the glass to prevent slipping. This mounting tape created an approximate 1-millimeter gap between the touch screen and the glass.
We could clearly draw an “S” on the Noritake GT-1P module’s touchscreen. On the competitor model, however, press was unreliable and drawing was unresponsive.
Next, we overlaid a 2-millimeter thick acrylic plate onto each module’s touchscreen.
We could clearly draw an “S” on the Noritake GT-1P module’s touchscreen. On the competitor model, however, press and drawing were unreliable.
Next, we overlaid a 5-millimeter thick acrylic plate onto each module’s touchscreen.
We could clearly draw an “S” on the Noritake GT-1P module’s touchscreen. On the competitor model, however, press and drawing were unresponsive.
The Noritake GT-1P module with its MPCT touchscreen clearly outperformed the competitor’s ITO touchscreen in a variety of conditions.
Here are the results:
