Abstract: A display panel and manufacturing methods thereof are provided. In one example, the display panel includes a flexible substrate having a display area and a non-display area, a dam structure located in the non-display area and disposed around the display area, one or more grooves disposed on the non-display area between the display area and the dam structure, and an organic encapsulation layer. In some examples, the organic encapsulation layer covers each of the display area, at least a portion of the non-display area, and the one or more grooves. Accordingly, a display device comprising the display panel is also provided. Thus, a flatness of the organic encapsulation layer may be improved and peeling may be reduced between the organic encapsulation layer and a substrate on which the organic encapsulation layer is disposed, thereby improving an overall quality of the finished display panel.

Abstract: The present disclosure provides a circuit board, an electrical component and a display apparatus. The circuit board includes a wiring pad which is divided into a plurality of sub-pads by bubble discharge paths, the bubble discharge paths intersect at a first point which is a geometric center of the wiring pad. By configuring bubble discharge paths with a shape of a straight line and as being intersected at the geometric center point of the wiring pad, the circuit board can discharge gas bubbles, generated when the wiring pad is soldered to a wiring terminal of other circuit board, from the geometric center point of the wiring pad to the edge thereof via the bubble discharge paths. Thus gas bubbles can be eliminated or reduced between the wiring pad and the wiring terminal when soldering, connection between the wiring pad and the wiring terminal can be more secure.
