It is also equipped with an LED backlight to provide a better display visibility in any lighting conditions. It has a high contrast ratio of 1400:1, fast response time of 3ms, and a wide viewing angle of up to 160 degrees.

The OK204-25-422-OY display module comes with a wide range of power supply options, ranging from 5V to 12V. It is also capable of operating in temperatures ranging from -20 to 70 degrees Celsius. In addition, this module employs an IC design which helps to reduce power consumption, thus providing more efficient operation.

The working principle of the OK204-25-422-OY display module is quite simple. It consists of a liquid crystal display (LCD) panel, a backlight, a controller board and a power supply. The LCD panel is made up of two different substrates which are separated by a thin layer of liquid crystal material. When a voltage is applied to the module, the layers of the LCD panel move in a spiral pattern, hence allowing light to pass through and display characters or images.

The backlight is used to provide a brighter display, especially in dim environments. The backlight works by reflecting and distributing the light evenly across the entire LCD. It consists of several small LED lights connected to a circuit board. A controller board, in turn, serves as the communication interface between the LCD and the power supply. The power supply provides the voltage necessary for the LCD panel to operate.

The OK204-25-422-OY display module is a versatile and highly efficient solution for various applications such as time and temperature display, liquid crystal indicator, data display, message terminals and more. Thanks to its outstanding features and working principle, the module is capable of providing excellent display performance and quality.
