LCD, OLED character and numeric displays are popular display modules commonly used in embedded system applications. The OK204-25-USB-OG is a type of character and numeric display module, which has been used in many applications. In this article, we will discuss the application field and working principle of the OK204-25-USB-OG.

Application Field of the OK204-25-USB-OG

The OK204-25-USB-OG is a highly reliable device which can be used in many applications. It is suitable for industrial, automobile, POS (Point Of Sale) systems, vending machines, and office equipment. It has a wide viewing angle of front-over-limit, and its high contrast, up to 1.5:1, and wide temperature range makes it particularly suitable for outdoor applications.

The OK204-25-USB-OG is also used in kiosks, medical devices, gaming machines, and other various applications. It is also suitable for applications where a large amount of information needs to be displayed, and where the display needs to be easy to read. The device has a wide range of backlight options, like 19 kinds of selectable blue and white LED backlight, which also makes it suitable for night operations.

OK204-25-USB-OG Working Principle

The OK204-25-USB-OG consists of a LCD panel, a controller, and an LED backlight. The LCD panel, also known as Active Matrix LCD, uses LCD pixels to display information. It is composed of a number of liquid crystal cells and a driver circuit. The driver circuit provides the power to the cells, which then interact with the light from the LED backlight, which passes through the cells and is then projected onto the display.

The controller of the OK204-25-USB-OG is a custom microcontroller, designed to interact with the module. It is responsible for controlling the communication interface, such as the USB and Serial interfaces, as well as for controlling the performance of the components such as the LCD panel, backlight, and its other parts. The controller also provides data flow between the computer and the display.

The LED backlight of the OK204-25-USB-OG is the main source of light for the LCD display. It is composed of a number of LEDs which provide light to the LCD pixels, and thus make the display visible in a range of lighting conditions. The LED backlight is also responsible for providing the module with its power.

Conclusion

Overall, the OK204-25-USB-OG is a versatile character and numeric display module which is suitable for a variety of applications. Its LCD panel, controller, and LED backlight combine to make it a reliable and high-performance device. The OK204-25-USB-OG is thus an ideal option for many applications, due to its numerous features and its cost-effectiveness.
