Abstract
This disclosure pertains to the technical field of display, and particularly to a method and an apparatus for aligning a display substrate by rubbing as well as a method and a system for preparing a display substrate. This method for aligning a display substrate by rubbing comprises: aligning the surface of the display substrate using a rubbing cloth in a rubbing process; and treating impurity particles produced in the rubbing process after the rubbing process, wherein the charges of the impurity particles are converted or eliminated to eliminate the electrostatic adsorbing effect between the impurity particles and the display substrate so as to remove the impurity particles produced in the rubbing process. Accordingly, an apparatus for aligning a display substrate by rubbing is further provided. This method and apparatus for aligning a display substrate by rubbing are capable of removing the strong “electrostatic adsorbing effect” between a display substrate and impurity particles so as to completely remove foreign matters in cooperation with ultrasonic oscillation or the action of washing and beating by water outside.
