Fast Full-Graphic Module with Touch Screen

The EA DIP180B-5NLWTP display module from ELECTRONIC ASSEMBLY was designed for use in industrial controllers. When equipped with an analog-resistive touch panel, applications involving user guidance and the display of information can be combined in a single unit.

The EA DIP180B-5NLWTP (link to the data sheet) is a full-graphic display with a resolution of 180 x 32 pixels; alphanumeric characters are displayed as graphics. Three integrated controllers of type PT6520 (or compatible) are used to control the left, center, and right sections of the display. A white LED background ensures crystal-clear display of information and exceptional readability under all lighting conditions.

The touch panel is linked to an external touch pad controller, or a controller with analog inputs. The panel operates similarly to that of a potentiometer. When a specific voltage is applied to the "Top-Bottom" input of the controller, a voltage proportionate to the Y-position of the point of contact is set at the "Left-Right" signal pins. The position of the point of contact in the X-axis is determined in the same way and a voltage is applied to the "Left-Right" pins. The output voltage that is then set at the "Top-Bottom" pins indicates the horizontal position of the point of contact.

The module provides a high level of contrast and fast response times thanks to the use of an LCD supertwist display. Even at extremely low operating temperatures of
-20 degrees Celsius, the display has a sufficient response time of approximately 2.5 seconds.

The modules feature an automatic temperature compensation facility, which eliminates the need to adjust the contrast during operation. The display is certified for operation between -20 and +70 degrees Celsius, making it ideal for many industrial applications. The module can be soldered directly to the printed circuit board to avoid complex assembly with mechanical components.
