Grey Background and Black Letters TN Positive Display Segment LCD Screen for Thermometer
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 segment LCD screen.
Dr Pan：Hello, Greg. Segment LCD screen can only be used for simple display content of numbers and characters at a specified position.
Dr Pan：For example, the display on clock, landline, calculator, etc.
Dr Pan：Number “8” is composed of 7 segments; number “0” is composed of 6 segments; number “1” is composed of 2 segments, etc.
Dr Pan：The character “electric fan” can be 1 segment, 2 segments and 4 segments as your requirements.
Dr Pan：Segment LCD usually adopts COB technology to realize it, especially when the segment size is big.
Dr Pan：It is supposed to be a replacement for LED segment display.
Dr Pan：If we compare it with LED segment display, it is more stylish and high class, but more expensive.
Dr Pan：If we compare it with dot-matrix LCD, the display content is very simple and absence of variation, but much cheaper.
Dr Pan：It is widely used in monochrome LCD screen: TN, HTN, STN, FSTN and VA because of relatively low cost.
Greg：Thank you, Dr Pan. Now I got it.
Dr Pan：Welcome to contact us if you have any questions.
