OLED-Display with USB and Touch

For the first time, ELECTRONIC ASSEMBLY presents the EA PLUGL128, a touch-sensitive OLED display that can be addressed directly via USB. It offers a resolution of 128 × 64 pixels with a 2.9″ screen diagonal. Since OLED technology enables each pixel to act as an independent light source, there is no angle-dependent contrast attenuation as is the case with LCD displays. The contrast of at least 2,000:1 remains constant over the entire viewing angle range of 170°. The display is extremely fast and still reacts smoothly and without delay even at temperatures as low as -40°C. The display is also extremely easy to read. It is protected by a robust, touch-sensitive glass pane. A gentle touch is all it takes to change displays or trigger actions.

Various graphic functions and character sets with German diacritics are already implemented. Thanks to various digital inputs and outputs, the display can take over small control tasks independently. Communication with microcontroller applications can take place via SPI, I2C or RS-232 interfaces. These are bidirectional and designed for 3.3V levels.

Version with screw terminals

In the Z version (EA PLUGL128-6GTCZ), the OLED display also features twelve screw terminals. External sensors or detectors can thus be connected easily and reliably. Two analog inputs enable voltage measurement up to 3.3V with direct display indication. In addition, this version is equipped with a 26-pin IDC tray connector, which provides additional I/Os and serial interfaces.

Possible applications include home automation and the upgrade of applications with text displays, as well as the control of smaller equipment.

EA PLUGL128 is the first member of the new display family EA PLUGxxx. Displays with 1.6″ and 2.2″ screen diagonals will soon also be available.
