Compact colour Module replaces monochrome Modules

The chromatic IPS-TFT panel EA TFT020-23 with a screen diagonal of 2 inches provides an extremely fine resolution, wide viewing angles and excellent sunlight readability. Its versatile, standardized interfaces facilitate the further development of products using monochrome displays.
Electronic Assembly designed the 2-inch TFT020-23 as a full-color alternative to monochrome graphic displays, which are widely used in handheld devices. Despite its compact size of only 36 x 52 mm, it features a very fine resolution of 240 x 320 pixels. With a brightness of 1,000 cd/m² it delivers brilliant images in the office, production or operating room, even in bright sunlight. Thanks to the IPS technology, the crisp, sharp contrast is preserved over a wide viewing angle of 160° and the colours remain unchanged, even at the most oblique viewing angle.
One connector combines all control lines of the display, the backlight and even the optional touch panel with 39 pins at 0.5 mm pitch. The version with capacitive touch surface including I²C controller is called EA TFT020-23AITC. This version measures 43 x 65 mm, the touch panel (PCAP) is optically bonded for a clear and low-reflection display.
The TFT display runs directly at 3.3 V and requires no additional auxiliary voltage. The SPI interface guarantees simple control with all common microcontrollers due to integrated display RAM. The same display can also be addressed via a classic RGB interface. Last but not least, connection to an 8- or 16-bit data bus is also possible.
Since both models were designed as handheld displays for heavy-duty outdoor use, they are able to cope with ambient temperatures of -20° C to +70° C. Their service life amounts to 50,000 hours.
Electronic Assembly does not stipulate a minimum order quantity for this product either and already delivers one piece of the TFT020-23 ex stock. With the excellent quality of its products, comprehensive support and an extreme long stock availability, the manufacturer supports the implementation of long-term product lines.

Round OLED displays, fast and temperature-stable

Circular, high contrast, ultra-thin, power-saving and stable over a very wide temperature range: The OLED displays of the EA W128128-XR series provide the ideal solution for compact handheld devices.
The new OLED displays from ELECTRONIC ASSEMBLY are just 2.05 mm thick. Its display area has a diameter of 30 mm (1.2") and consists of a passive matrix of 128 x 128 pixels. This format qualifies perfectly for the display of analogue measurement scales. The external dimensions of the entire module, including the connection cable, amount to almost 37x41mm.
As a self-luminous display technology, OLEDs offer numerous advantages compared to LCDs. In addition to the extremely flat design, the advantages include very wide viewing angles all around up to almost 180°. Thanks to the deep black level, this display technology impresses with a contrast ratio of >2000:1. The brightness of the controlled areas in the 50% checkerboard pattern is 80cd/m2. At first glance, this may not sound much, but it is brilliant even in bright daylight. With 10 µs, the display reacts extremely fast, even at ice-cold -40°C as well as scorching +80°C.
The integrated controller SSD1327ZB requires a supply voltage of 3.3V, the display 14.5V. The current consumption for displaying a checkerboard pattern typically amounts to 24 mA which is a very economical consumption. The display is controlled via SPI protocol via a 24-pole ZIFF connection. Thanks to numerous initialization examples, measured values, graphics and icons can be displayed quickly and with high contrast.
The EA W128128-XR displays are offered in three colours: EA W128128-XRLG with yellow, EA W128128-XRLW with white and EA W128128-XRLB with blue pixels on a black background. The typical lifetime of the yellow display amounts to 50,000 hours. As a rule, it takes 20,000 hours for white and blue to lose half their brightness.
Owing to its compact design, the energy-saving display and the extreme temperature stability, the EA W128128-XR series is excellently suited for use in mobile handheld devices. A USB test board and OLED simulation software for Windows are also available for quick testing of individual applications.

High-contrast OLED with USB interface

Especially for small monitoring and control tasks, the display specialist ELECTRONIC ASSEMBLY has developed a graphic OLED display with touch-sensitive front made of real glass.
The brand new EA PLUGS102-6 is not only a display, but also a full control unit featuring a wide range of interfaces. Its 36 x 25 mm display area offers a resolution of 102 x 64 pixels. Since every pixel in OLEDs represents a light source, this panel boasts unbeatably brilliant color, low black levels and strong contrasts compared to any LCD displays.
All these features are provided from any viewing angle at almost 180°, because OLEDs do not exhibit the LCD-typical weak contrast at oblique viewing angles. A separate backlight is not necessary. The display brightness can be adjusted by software. Automatic screen saver modes prevent the possible burn-in of static image content.
Thanks to the integrated USB interface, the OLED module can be quickly and easily put into operation. Just plug it in and the display will be automatically powered. The data transfer takes place serially, either via USB, SPI, RS232 or I2C connection.
For measurement and control tasks, the EA PLUGS102-6 is equipped with eight freely configurable digital I/O interfaces, two analog inputs and one PWM and one analog output. A small loudspeaker is also integrated.
The EA PLUGS102-6 recognizes high-level language-like graphics commands, which can be mastered even without any previous knowledge. In addition to eight integrated fonts, the display also features a number of sophisticated graphic functions. The time-consuming development of character sets and graphic routines is not necessary. Text and graphic elements can be mixed with each other at will, they can be positioned pixel-precisely and provided with blink attributes (on/off, inverse). Up to 256 images and the same number of macros can be stored in the internal memory.
The complete OLED module measures 55 x 54 x 15 mm. Its supply voltage, if not supplied via USB, may range from 3.3 to 5 V. If all pixels are enabled, it typically requires 137 mA or 97 mA. Its operating temperature ranges from -20 to 70 °C. For quick mounting, it is simply glued upright or crosswise into the front panel.

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.
