Display modules are an integral part of electronic systems and present system data to the user in an intuitively readable format. The LK204-25-R-V series is one of a number of display modules which provide a range of features to meet the needs of any engineering project. This article outlines the application fields and working principles of the LK204-25-R-V display module.

Features

The LK204-25-R-V display module offers an excellent balance between form, function, and cost. It is a small, lightweight LCD display module with a viewing angle of 160 degrees. It boasts a 8x2 character display, with each character being 12 x 8 pixels, resulting in an overall resolution of 96 x 16 pixels. The device is also capable of displaying eight special characters and can be used with 12V (DC) or 24V (DC) power. It is an ideal module for use in a number of different applications.

Applications

For applications that require a small display with a wide view angle, the LK204-25-R-V display module is an ideal choice. It is typically used in the following applications: automotive, medical, industrial control, instrumentation, and consumer electronics. Its low power consumption and robust construction make it suitable for any application that requires a display.

The LK204-25-R-V display module is particularly well suited to medical and industrial control applications. In medical applications, the device can be used to display vital signs, such as heartbeat and respiration, while in industrial control applications, it can be used to provide the user with vital system information. In addition, the module can be used in instrumentation applications, such as temperature and humidity monitoring, as well as in consumer electronics, for display of text and other data.

Working Principle

The LK204-25-R-V display module uses a Liquid Crystal Display (LCD). This type of technology works by blocking light from passing through a layer of liquid crystal molecules when an electrical field is applied. When the electrical field is applied, the molecules align in a specific pattern, which affects the light\'s ability to pass through them and thus produces the desired image.

The LK204-25-R-V display module contains two layers of liquid crystals. The front layer has a black mask applied to it, which blocks light from passing. This layer is known as the front polarizer. The rear layer is the liquid crystal layer, which consists of a number of crystal molecules which can be aligned through the application of an electrical field. This layer is known as the rear polarizer. Between the two polarizers is a transparent layer, which also contains the liquid crystal molecules.

To generate the image, the module applies an electrical field across the two polarizers. This causes the liquid crystal molecules in the rear polarizer to align in a specific pattern, which affects the amount of light that is able to pass through the module. This process is known as electro-optic switching. Depending on the application, the module can be used to display text, pictures, or other data.

Conclusion

The LK204-25-R-V display module is a versatile, cost-effective LCD display module. It is suitable for a range of applications, including medical, industrial control, instrumentation, and consumer electronics. Its working principle is based on electro-optic switching, which allows it to display text, images, and other data. If you are looking for a reliable, small display module with a wide viewing angle, the LK204-25-R-V could be an excellent choice.
