All about mono displays
Mono displays are a type of display, just like TFT displays and OLED displays. Mono displays can be recognized by their mainly black and white image. They are often smaller in size and used in for example electronic shelf labeling in supermarkets or desk phones.
Mono display technologies
A segment display can display both numbers and letters which are made up of segments, not pixels. A segment can also make symbols like plus and minus signs, units of measurement and custom icons. Each symbol is counted as one segment.
A segment mono display is restricted to displaying numbers, Roman letters and a set number of symbols. When the display needs to show something other than this, a character of graphic display might be a better choice. When the symbols need to be on a different location on the display, a new display will need to be made.
Segment displays are often used in devices like alarm clocks. They are easy to maintain and cost effective to develop.
Character mono displays are also known as dot matrix displays. These displays display a number of rows with characters. They usually have 1 to 4 rows with 16 to 40 characters on each row. When a character display consists of 2 x 24 characters, a row cannot be longer than 24 characters. The characters to be displayed can be placed on any of the 24 character spots.
Each character consists of 5 x 8 dots and are individually controlled. A character can be a number, Roman letter, foreign letter or limited number of symbols.
Character mono displays are often used when more characters than those of the Roman alphabet need to be displayed. They are relatively easy to use and less costly than graphic displays.
Graphic mono displays offer users a great amount of flexibility. They consist of pixels aligned in rows and columns. Each pixel can be individually controlled to display text, graphic images or a combination of both.
These graphic mono displays are ofted used in applications that require full control of the entire display. They are often a little bigger than other mono displays, more expensive and more complex to use. But on the other hand can display much more complicated and detailed images.
