High Contrast Alphanumeric Display from EA
New high contrast displays.
Munich, Germany — New from Electronic Assembly is its EA DIP203-4 LCD module for applications that require exceptional readability. The module provides a high-contrast, alphanumeric LCD supertwist display for four rows of text at 20 characters per row. Standard LED background illumination makes the text even more legible.

The dot-matrix display comes in three variations. Users can choose from black text on a yellow/green background, white text on a blue background, and black text on a white background. An automatic temperature compensation facility eliminates the need to adjust the contrast.

The display is driven by a built-in type SSD1803 controller, which is 90 percent compatible with the popular HD44780 controller. The character set that ships with the display supports 240 letters, numbers, and symbols; users can also define eight characters of their own. The controller receives its control commands from a fast SPI interface. A 4 and 8-bit databus interface is also available for the display.

The EA DIP203-4 is particularly easy to install, since no mechanical assembly is required. Simply insert the module into the circuit board and solder. Power is supplied through a single 3.3V line. The LED illumination requires a constant 150mA for the green/yellow display and a constant 45mA for the blue/white and black/white displays.

The wide operating temperature range of -20 to +70°C) makes the display the right candidate for applications in many industrial environments.

Additional variations with the same casing and pinout are also available. Customers can choose from dot-matrix models that support 1 x 8 or 2 x 16 characters as well as a full-graphic version with 122 x 32 pixel resolution.
