Abstract: The present application provides a method for detecting coagula on a coater head. The method includes: detecting a thickness value of a coating material (2) on a substrate along a coating direction thereof; acquiring a first thickness value and a second thickness value, and calculating a difference value; and comparing an absolute value of the difference value with a preset value, and outputting a feedback signal if the absolute value of the difference value exceeds the preset value.

Abstract: A touch panel manufacturing method, a touch panel and a display device are provided, and the method includes: forming a black frame on a substrate; forming a removable adhesive layer in a display region of the substrate having the black frame; forming a metal layer on the black frame and the removable adhesive layer; removing the removable adhesive layer in the display region and a first part of the metal layer located in the display region; performing photolithography on the substrate where the removable adhesive layer and first part of the metal layer have been removed, thus producing a touch panel.

Abstract: Embodiments of the present disclosure provide a device and a method for detecting breakage of a substrate and a substrate transfer system. The device includes a first electrode and a second electrode arranged oppositely, a power source, and a detector. The power source may provide an alternating current voltage to the first electrode and the second electrode. The detector is arranged between the power source and the first electrode or the second electrode and may detect, when the substrate is placed between the first electrode and the second electrode, a current value in the substrate, and determine whether the substrate is damaged based on the detected current value.
