How to Choose Monochrome LCD Screen?
1. Understand the customer's product use environment
For example, whether it is outdoor or indoor. Usually outdoor products usually have to choose high contrast, LCD display mode is best positive display, negative display in the outdoor will not see too clearly. In addition, outdoor to consider the anti-UV and anti-glare, usually indoor LCD screen selection will be wider.
2. Consider the sales area and use
To choose the working temperature of the LCD screen according to the end sales area and use of the customer's products. For example, the products exported to Russia, basically will be made into wide temperature, super wide temperature.
3. Consider the customer's external power supply
Generally if the battery power supply, then the LCD should consider the power consumption, voltage selection of low voltage, preferably without backlight, join must be used, then the best LCD can be made semi-transparent, backlight use can be controlled, in the case of dark light backlight open, external light brighter can be closed backlight.
4. Look at the customer's desired product effect to choose the material and mode of the LCD screen
For example, if the customer wants white characters on a black background, then we can only do VA with white backlight, if it is white characters on a blue background, then we will do HTN or STN negative display, black characters on a white background, usually we will use TN, HTN or FSTN.
5. Look at the final customer wants to display the content
If you must display Chinese characters and need to change the screen work, then you can only choose the dot matrix screen, if only display characters and numbers also need to change the screen, then we will choose the character dot matrix screen, if the customer's display content is basically fixed, do not need to change the screen, then we recommend the pen type LCD screen.
Monochrome LCD Screen How to Classify
1. The content of its display up to classification
Segment LCDs, graphic dot matrix LCDs (with and without Chinese font, respectively), COB/zifu/' target='_blank'>character LCDs
2. From the process above to classification
Segment code LCD, COB LCD, COG LCD, TAB LCD
3. From the background of its display to classification
Yellow-green LCD, blue film LCD, gray film LCD
4. From the use of materials to classify the above
VA (BTN), TN, HTN, STN, FSTN. segment code LCDs are possible to use all materials, dot matrix LCDs use STN a little more, the other are relatively less.
5. Use dot matrix to distinguish
For example: 12232, 12832, 12864, 19264, 160128, 160160, 24064, 240120, 320240 and so on, our most commonly used is 12232, 12864, 24064, 320240.
6. From the working temperature to distinguish
Divided into room temperature (-20 ~ 70 degrees), wide temperature (lower than -20 or higher than 70 degrees), from the perspective of classification, 6-point view, 12-point view, that is to say, the clock's 6 o'clock direction or 12 o'clock direction to see the display.
The above is to teach you how to choose monochrome LCD, as well as monochrome LCD his a classification situation, can be said to be after all detailed should be able to help you, really do not understand the staff can also consult SONYTEK, we will teach you how to choose the right monochrome LCD, choose a more suitable for their own products LCD.
