STN Dot Matrix Negative Display Blue Background and White Letters LCD Screen
Dr Pan: Welcome to DISPLAY Museum. I am Dr Pan, the curator of Museum.
Greg: Hello, Dr Pan. I am Greg. I came here to learn about dot matrix LCD Screen.
Dr Pan: Hello, Greg. Dot matrix LCD screen consists of many arrays of dots.
Dr Pan: Take 128 * 64 dot matrix LCD for example, there are 128 points horizontally and 64 points vertically.
Dr Pan: And 8192 points in total.
Dr Pan: Dot matrix LCD usually resorts to COG technology to realize it, especially when the dot size is small.
Dr Pan: Each dot is independently controlled and it can display complex variable character or pattern.
Dr Pan: On some level, it is an advanced version of segment LCD. Each dot is a segment.
Dr Pan: Number “8” is composed of only 7 segments for segment LCD
Dr Pan: and it is composed of many segments for dot matrix LCD.
Dr Pan: If we compare it with segment LCD, the display content is complex and variable, but much more expensive.
Dr Pan: Under normal conditions, people still want monochrome dot matrix LCD screen because the size can be customized and the price is much cheaper.
Greg: Thank you, Dr Pan. Now I got it.
Dr Pan: Welcome to contact us if you have any questions.
