1. There are differences between row and column drivers.
2. Row drive means that the data is sent to the LED display by row, and the data of each row is displayed successively, and then the next row is refreshed.
Column drive means that the data is sent to the LED display in columns, and the data of each column is displayed in turn, and then the next column is refreshed.
3. The difference between row drive and column drive lies in the different ways of data transmission. The
row driver needs to send data by row, so it takes longer to refresh the entire screen, but multiple rows of data can be displayed at the same time.
Column drivers need to send data by column, so it takes less time to refresh the entire screen, but only one column of data can be displayed at the same time.
According to the specific application scenarios and needs, choosing the appropriate driving mode can improve the performance and effect of the LED display.
The row driver and column driver of the LED display are two different driving methods. Line drive is to control the switching state of the row to control the LED on and off, and the LED of each row will be turned on or off at the same time. The column drive is to control the LED by controlling the switching state of the column, and the LED of each column will be turned on or off at the same time.
The row driven mode is suitable for static display and can display multiple lines of information at the same time. The column driven mode is suitable for dynamic display, which can achieve high refresh rate and is suitable for displaying dynamic images. Each of the two driving modes has its advantages and disadvantages, and the appropriate driving mode is selected according to the specific application requirements.
