Overview of 2009

Slimline with Touch

With its 39mm width and 40mm height the new EA DOGS102-6 is the most compact graphic display by ELECTRONIC ASSEMBLY. Even with this small size an analogue touch panel is available. All touch areas are defined by software. With a typical touch area of 10x10mm up to 8 touch keys have room. This is more than enough for the most applications. Thanks to the extreme compact outline, the newest member of the EA DOG family is perfect to become assembled into a 19" rack with 1 RU. It is also ideal for wall-mounted switches in premises; it could become a simple display, switch or control unit there. With 102x64 dots there is enough space for multi-line text and graphics. Congenial to the display ELECTRONIC ASSEMBLY provides backlight units in white and amber color, as well as a duo colored version in green and red. The white backlight does reach a brightness of incredible 2000cd/m². This leads together with the new super-white polarizor an extreme brillant display. Important for the quality is to know that 4(!) pcs. long-life NICHIA LED's are assembled. The connection to a microcontroller is done via serial interface SPI.. The power supply is single 2.7 ~ 3.3V. Current consumption stays below 150uA. The EA DOG series provides some more display sizes as character and graphic types.

Mounting for free

This is the new solution: put the graphic display and the backlight together and solder into the pc board. An extra mounting is no longer required. The new graphics displays from DOG-series do provide a resolution of 128x64 dots. The mechanical mounting as well as the electrical contact is done via the 26 pins, pitch 1/10 inch. Simple and reliable. Connection is done via serial interface SPI. Data transmission rate is up to 20MHz without any busyflag operation. The displays do have very compact outline dimension of 55x46mm and an extreme narrow edge. There's a low-power graphics controller built-in already. The modern chip design leads to a power consumption of 150uA only (single supply 3.3V). There is no additional voltage required and contrast is held stady over unsteady supply voltage and ambient temperature automatically. Contrast adjustment is done via software control. Operating temperature range is from -20 up to +70°C. ELECTRONIC ASSEMBLY do provide some fitting white, blue, yellow/green, amber and red modules for backlighting. Even a full color RGB is available. All those are LED design and easy stick together. They do provide highest intensity and even illumination. Switching on and off or dimming can be done all the time. The white backlight is perfect for all battery powered systems, because already with 3mA brigthness gives total satisfaction. Those combination of various display technologies (positive, negative, blue, green, black) and different backlight colors (white, blue, amber, yellow/green, red) enables widest flexibility in design.

Every color from 1 pc.

This is one of a lot features to the EA DOG-series. The super bright backlight is extreme even and available in various different colours. Also a RGB backlight is included. The contrast and viewing angle of the STN and FSTN displays is without any reproval. More than that: the unbelievable compact design and the integrated graphic controller with SPI interface makes it straightforward. The displays will be soldered direct onto a pcb, and for programming there are ready made character sets and some routines for initialisation available. Furthermore there is a testboard for easy USB connection and a gratis simulation software for Windows on hand. Outstanding is the low current consumption of 150~350uA only at single supply +3.3V (depends on display size). There is no additional voltage needed. Contrast is held steady over unsteady supply voltage and over the whole ambient temperature automatically. Contrast adjustment is done via software control. Because this display series was developed for industrial application, operating temperature range is wide with -20 up to +70°C. Optionally display can be equipped by a touch panel. ELECTRONIC ASSEMBLY does offer the EA DOG-series with 132x32 and 128x64 dots (2 different sizes). With 7 different backlights these display do match to every design. The white backlight e.g. is perfect for battery powered systems because it is bright enough even at low current of 5mA. Last but not least all displays are with all colours available ex stock !
