Versatile Full-Graphic Display for Quick and Easy Installation

The EA DOGXL160-7 graphic display from ELECTRONIC ASSEMBLY enhances the company's chip-on-glass product line by adding a further display unit with 160 x 104 pixel resolution. This makes it possible to accommodate up to 13 lines of 26 characters each in normal type and 6 lines of 20 characters each in large type. Each pixel is controlled separately. The EA DOGXL160-7 also provides developers with a large range of variants and combination options with respect to color and control.

Five combinations of display and background color are available as is STN and FSTN technology with high contrast. The display units can also be combined with seven different lighting schemes (white, yellow/green, blue, red, amber and green), with one model even supporting the entire color spectrum as a RGB backlight. This leads to a wide variety of variations that blend seamlessly with almost all conceivable designs.

The displays feature an integrated graphics controller of type UC1610 in addition to the accompanying graphics RAM. Developers can choose from four serial interfaces to connect to the outside world – a 4-wire, 8-bit SPI, a 3-wire, 8-bit SPI, a 3-wire, 9-bit SPI, and a 2-wire I2C. In 2-wire I2C mode, one of two base addresses can be set so that two displays can be operated using a single I2C bus.

The new displays are just as easy to handle from a wiring and installation perspective as other members of the EA DOG family and require a single power supply of 2.6 to 3.3 volts, whereby a load of only 700 microamperes is placed on the network. A separate power source is needed for LED background illumination and can supply anywhere from 10 to 150 milliamperes, depending on the variant. No mechanical assembly is required to connect to the circuit board. Simply insert, solder, and you're finished!

Despite all of this, EA DOGXL160-7 family displays are very compact (78 x 64 millimeters of space is sufficient) and are no taller than 6.5 millimeters, even with LED background illumination. An operating temperature range of -20 to +70 °C also makes the displays compatible with many applications in the industrial and medical sectors.

A complete line of accessories is available to developers and includes an USB test board for connecting to Windows PCs, a touch panel with analog 4-wire interface, and character sets with font editor. Additional fonts with Cyrillic, Greek, or Arabic character sets, for example, can be derived from Windows fonts.
