dot lcd display quotation

Liquid crystal display (LCD) is a flat panel display that uses the light modulating properties of liquid crystals. Liquid crystals do not produce light directly, instead using a backlight or reflector to produce images in colour or monochrome.

Dr Pan: Hello, Greg. Dot matrix LCD screen consists of many arrays of dots. Take 128 * 64 dot matrix LCD for example, there are 128 points horizontally and 64 points vertically. And 8192 points in total. Dot-matrix LCD usually resorts to COG technology to realize it, especially when the dot size is small. Each dot is independently controlled and it can display complex variable character or pattern. On some level, it is an advanced version of segment LCD. Each dot is a segment. Number “8” is composed of only 7 segments for segment LCD and it is composed of many segments for dot matrix LCD. If we compare it with segment LCD, the display content is complex and variable, but much more expensive. TFT LCD and OLED are both dot matrix, more stylish and high class, perfect choice for high end devices. Under normal conditions, people still want monochrome dot matrix LCD screen because the size can be customized and the price is much cheaper.
