OK204-25-422-OR-VPT-E

The OK204-25-422-OR-VPT-E is a type of display modules that are used for LCD, OLED characters and numerics. This type of display module has a wide range of applications. It is commonly used for industrial systems, medical equipment, portable instruments, control and measurement equipment, household appliances, and automobile navigation systems. It is also used for video, telecommunication and broadcasting systems.

Features

• It has a 5x7 dot matrix LCD display.
• It has two RGB LED drivers with a power supply of DC 5V.
• It has an excellent wide viewing angle of up to 90°.
• It is equipped with a 4-wire serial interface.
• It has good background lighting and uniform lighting effect.
• It has wide temperature range of -20℃~70℃.
• It is RoHS compliant.

Working Principle

The OK204-25-422-OR-VPT-E display module works by driving an LCD panel with the appropriate voltage. This voltage will cause the LCD to turn on and off, depending on the voltage level. When the voltage is high, the LCD will be on and when the voltage is low, it will be off. The LCD will also be able to display characters and numerals. The LCD panel consists of two transparent electrodes, which are made of two parallel glass plates. When voltage is applied to these plates, it causes the molecules of the liquid crystal material to align in a particular pattern. This pattern is used to generate characters and numerals. Depending on the voltage applied to the liquid crystal, the light transmission can be changed by the LCD panel.

Conclusion

The OK204-25-422-OR-VPT-E display module is a LCD, OLED character and numeric display module that has a wide range of applications. It has excellent viewing angles, good background lighting and uniform lighting effect. It is also equipped with a 4-wire serial interface. The working principle of the module is based on driving an LCD panel with the appropriate voltage, which causes the LCD to turn on and off, and also to display characters and numerals.
