Since line by line scanning allows me to control the 5ms text of each line display, it can display the blinking character of the queue. Should each line display less control?
According to the rule, the visual stay frequency is calculated, the line scanning frequency is 50HZ, the naked eye looks flashing, takes the 50HZ threshold, the dot matrix display between 1S/50=20mS, namely needs 20mS to carry on the scanning;Each line 5mS, a total of 8 rows, repeated scanning room 5mS*8=40mS>>20mS, looked flashingThe 2.52mS jump between the scans is too short to show the brightness
Think over the details:Show that the contents of the first row have no effect, the level is canceled, the row of selected lines, the second line of instant display of the contents of the line
Short relation between effect and extension ~!Can not be hidden processing ~!
