When comparing LCD and OLED technology, it is important to review and become familiar with the differences and similarities between them, specifically when looking at Character and Graphic displays. A few key points that are unique to LCD Character and Graphic displays are: they are highly customizable, one can pick between different bezel sizes, there is a variety of backlight color options, and there are three different polarize choices- transmissive, reflective or transflective. LCD displays also come in a positive or a negative mode, allowing the user to create a look that is most ideal for their end application.
OLED Character and Graphic displays have no backlight, thus giving them a high contrast ratio. OLEDs also have a higher refresh rate, wider viewing angles and increased temperature ranges, making these displays great for colder weather. Lastly, OLEDs have a smaller footprint than LCDs. A few similarities between LCD and OLED Character and Graphic displays are the size ranges, that both technologies have similar power consumption, and the Character displays come with built-in font tables. Both Character and Graphic LCD and OLEDs are offered as modules, meaning there is no need for extra boards or logic.
