LCDs
Character LCD displays are available in dot matrix format 5x7 and 5x8 per character. Mechanical construction includes Chip on Board (COB) and Chip on Glass (COG). Positive and negative modes are available to create alternative appearances. Character LCD modules are available in reflective (no backlight), and transmissive or transflective types (with LED backlight). Interfaces are standard 8 bit/4 bit but we can offer some displays with 4 bit only, SPI, or I2C interface. The majority of character LCD controllers are HD44780 equivalent and include on board character sets, the standard being English/Japanese. Other character sets available on demand are western European, eastern European, Scandinavian European, Cyrillic (Russian), and Hebrew/Arabic. We offer 5V operating voltage as standard but for low power options, we can offer 3V and 3.6V types. There are also a variety of pin out connections to suit your requirements, in both SIL (single in line) and DIL (dual in line) format.
Graphic LCD displays also have mechanical construction formats of Chip on Board (COB), Chip on Glass (COG), and TAB (Tape Automated Bonded) types. Positive and negative modes are available to create alternative appearances. Graphic LCD modules are available in reflective (no backlight), and transmissive or transflective types (with LED backlight). The LED backlights are available in various colours including yellow/green, white, and RGB. Interfaces include parallel, I2C, and serial. The majority of graphic LCD controllers do not include on board character sets, however we can offer a range of products which include T6963C (or equivalent) and ST7920 controllers which provide English and/or Chinese characters. Some ST7920 based modules are formatted to have the same footprint as industry standard 16x2 and 20x2 character LCDs. We can offer 3V, 3.3V, 3.6V, and 5V operating voltage options.
E-paper displays offer an ultra low power graphic option, with high contrast and very wide viewing angles. These bi-stable LCDs require ultra low current for "deep sleep" mode, with on chip display RAM, serial peripheral interface and I2C signal master interface.
