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.

Abstract: Provided are a printing device and a method for an LED retaining wall of a display panel. The device includes a motion control system, an adsorption apparatus, a measuring system, a Z-axis controller, a target multi-needle module and a target station. The motion control system is configured to control printing of a target LED retaining wall on an upper surface of a target substrate on the target station. The adsorption apparatus is configured to make a lower surface of the target substrate adsorbed onto a sucker by a vacuum pump. The measuring system includes a sensor and a sensor controller, and the sensor is configured to measure flatness data of the target substrate. The Z-axis controller is configured to control a printing receiving distance between the target multi-needle module and the upper surface of the target substrate.
