The OK202-25-OR is an LCD display module used to display numeric and character data. It is best suited for applications that require clear and accurate information to be displayed. The module has good electrical features and optical parameters, excellent color performance and wide viewing angle.

The OK202-25-OR module is made up of a FSTN LCD panel, a controller board, a backlight, and a connector. It has a viewing area size of 128 x 64 pixels, a display type of FSTN, a viewing angle of 6:00 and a viewing distance of 6.0m. The LCD module has a contrast ratio of 8:1, a brightness of 80nits, a response time of 10ms, an input voltage of 5V and a working environment temperature of -20°C to 70°C. Its power consumption is 8.0W. The module is RoHS compliant and uses an industry standard HD44780 compatible controller.

The working principle of the OK202-25-OR module is based on the classical Refresh Cyclic Method. The FSTN LCD panel is made up of a matrix of pixels organized in rows and columns. When VRAM is changed and "refreshed" during the Refresh Cyclic Method, a common data row is selected. Data bits of the selected row are written into the LCD panel through the data drive circuit, and then the common row is changed. Then the next row is selected and data is written into it in the same manner. This process is repeated until all the rows of the selected area have been refreshed.

The OK202-25-OR module is widely used in various applications such as medical instruments, industrial panels, audio-visual systems, POS terminals, and portable electronic devices. It is an ideal solution for displaying numeric and character data in any application. With its wide viewing angle, excellent color performance and high contrast ratio, this LCD module is the perfect choice for accurate and reliable data display.
