Working Principle

The OK202-25-USB-OY-E display module relies on the OLED or LCD display for displaying different patterns, symbols and information. When the device is powered on, the LCD or OLED panel of the module will generate a certain amount of light, corresponding to the image sent by the microprocessor. The current in the panel of the LCD or OLED module is regulated and maintained within a certain range by the voltage regulator to adjust the brightness of the display. The display is also connected to a CMOS buffer, which drives the display.

The OK202-25-USB-OY-E display module is mainly composed of an OLED display module, an LCD display module, a voltage regulator, a CMOS buffer and a microprocessor. The LCD or OLED display panel is the major component of the module. It converts the microprocessor’s data and applies it to the corresponding liquid crystal surface to display or indicate information. The microprocessor of the module is mainly used to calculate and control the various parameters of the display module, receive the external signals and send the corresponding display command to the display.

In short, the OK202-25-USB-OY-E display module is used for digital and analog signal display. It utilizes an OLED or LCD display, a voltage regulator, a CMOS buffer, and a microprocessor in combination for displaying images and information. The microprocessor is mainly responsible for calculating, controlling and sending the display command to the display.
