Compact displays for quick assembly

Featuring external dimensions of just 40 x 20 mm, the EA DIPS082 precisely fits into 19" rack systems with one height unit (1 U). The saying "time is money" also applies to this industry, as it does everywhere - especially when it comes to assembling. For this reason, the compact EA DIPS082 dot matrix panel including pins with a grid of 2.54 mm (1/10”) is soldered directly into the circuit board or plugged into a socket. No additional fixing screws, spacer sleeves or connecting cables are required. This saves material and shortens production time per module by two to three minutes.
The high-contrast LCD Supertwist display can display two lines with 8 characters measuring 5.01 mm each in height or, as EA 8081-A3N, one line with eight characters almost twice as high (7.15 mm). His ROM already contains 192 ASCII characters. Eight freely defined characters can be added to this character set. All displays are supplied with standard controllers, ensuring that existing hardware and software can be used without modification.
The EA DIPS082 is compatible with HD44780 and is connected to a 4- or 8-bit data bus. The supply voltage of the unit may optionally be ±2.7 V, ±3.3 V or 5 V (at 2 mA). The operating temperature range is from -20 to 70 °C.
The display is also available as EA DIPS082-HNLED with integrated LED backlight. It requires 5 V as supply voltage, with a typical current consumption of 50 mA (max. 80 mA). By modifying certain resistors, the lighting can also be switched and regulated.
The EA DIPS082 is part of a family of quickly mountable dot matrix displays. Currently, the EA DIP series also includes the following models: There are text displays in the format 68 (75) mm x 27 mm with 1 x 8, 2 x 16 and 4 x 20 characters, as well as a graphic display with 122 x 32 pixels. The 75 mm x 46 mm format offers a text display with 4 x 20 characters and a graphic display with 128 x 64 pixels. The largest graphic display has a size of 113 x 70 mm and a resolution of 240 x 128 pixels.
A long availability of more than 10 years, an excellent support and highest quality guarantee you a safe future. Touch panels are optionally available for the graphic displays.

Displays for low-power devices

Lowpower Displays LCD für Handheld mobile Geräte

The display specialist ELECTRONIC ASSEMBLY has launched a multi-faceted EA DOG product family especially designed for low-power handheld applications. They are all operated at 3.3 V as a standard and require hardly more than 150 ~ 350 µA. The optional LED illumination is also designed for 3.3 V. The brightest white LED starts at 3 mA.
The panels, which are only 2 mm thick, are currently available as text and graphic displays in 10 different sizes and five different display technologies: as transmissive, reflective or blue STN as well as positive or negative FSTN. All technologies are standard and available starting from 1 unit. The displays can be combined with six separate backlights in white, amber, blue, red, yellow/green and full colour by simply plugging them together.
Owing to the compact design, an extremely flat display module with a maximum height of 5.8 mm is obtained when combined with lighting. Without any additional mounting effort, it can be soldered directly onto the circuit board with a 2.54 mm grid.
The text displays are supplied with 1*8, 2*16, 4*10 (switchable to double font height 2*10) as well as 4*16 and 4*20 characters. The graphic variants are available in the resolutions 122*32, 102*64, 160*104, 240*64 and 240*128 pixels. The outer dimensions vary between 39 x 41 and 94 x 67 mm. All displays are equipped with a SPI interface, the text displays additionally have a 4-/8-bit interface and some displays can also be addressed via I²C.
Thanks to integrated temperature compensation, the thermal application range of the displays covers temperatures from -20 to 70 °C.
As a further special feature, individual EA DOGs support English, European and Cyrillic character sets in a single display. The displays are available in large quantities as well as small quantities at short notice. ELECTRONIC ASSEMBLY guarantees a long-term availability of up to 10 years.
Developers have access to an USB test board with PC connection and suitable Windows software, including a free simulator and a great deal of C and microcontroller codes for an easy system start and prototyping.

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.
