Abstract

The embodiment of the present disclosure provides a method and device for printing a reflecting layer of a backlight panel. The method includes performing first correction processing on at least two piezoelectric injection valves firstly, then acquiring specification parameters of the backlight panel, generating moving paths of the at least two piezoelectric injection valves according to the specification parameters of the backlight panel, and controlling the corrected piezoelectric injection valves to print according to the moving paths. The reflecting layer is printed by controlling the piezoelectric injection valves to achieve stepless change in the film thickness of the reflecting layer, and the method can be implemented before or after the die bonding process. Compared with the conventional silk-screen printing method, the method is more flexible, which can not only avoid influence on the solder paste printing accuracy of the backlight panel, but also prevent the cured reflecting layer from warping, so as to ensure the preparation accuracy of the reflecting layer.
