DOGS104-A Series Compact Low-Power Flexible (4×10) Character LCD


DISPLAY VISIONS’ DOGS104-A series compact low-power pin connected chip-on-glass character LCD

DISPLAY VISIONS EA’s DOGS104-A series character LCDs are available in an FSTN pos. transflective, STN neg. blue transmissive, and FSTN pos. white reflective version. These displays have a 2.54 mm pitch and can be soldered directly or plugged into socket strips. Therefore, cumbersome gluing procedures, the need for designing a special mounting device, and error-prone cable connections that may lose contact are no longer a concern.

This LCD family was designed for use in the German industry and will have an availability of 15+ years. The extremely efficient ratio of external dimensions [36 mm x 27.5 mm x 2.6 mm (or 4.6 mm including LED backlight)] to the active display area helps in designing very compact devices. Furthermore, its low-power use [single supply 3.3 V to 5.5 V (typically 250 µA)] makes it ideal for handheld applications.

The EA 9780-4USB development board and free Windows simulator are all users require to evaluate pin-connected chip-on-glass LCDs with and without backlight. Simply plug the 2.54 mm connector pins of the display into the socket strips of the development board. Proprietary hardware or software development is not required. Decisions can be made quickly at a minimum expense.
