Abstract: A display panel and a manufacturing method thereof are provided. The display panel includes: an array substrate with a first protrusion defined thereon; a color filter substrate disposed opposite to the array substrate; a supporting structure, wherein an end of the supporting structure is connected to a lateral side of the color filter substrate, another end of the supporting structure is connected to a lateral side of the array substrate, and the first protrusion is embedded into the supporting structure. The first protrusion is formed on a side of the array substrate near the color filter substrate. Therefore, when the supporting structure of the color filter substrate is aligned and attached to the array substrate, the first protrusion can be embedded into the supporting structure, thereby preventing the supporting structure from being moved. Thus, risk of alignment error is reduced, and abnormality of the display panel is prevented.

Abstract: A fingerprint collection device and a display panel are provided. The fingerprint collection device includes: a base substrate, a driving circuit layer, a first passivation layer, a photodiode, a second passivation layer, and an electrode layer. A first electrode portion is electrically connected to the photodiode through a second via. A second electrode portion is electrically connected to a first signal trace and a second signal trace through a third via and a fourth via to form a bridge structure. Since the third via, the fourth via, and the second via are formed in same process, one process can be saved.

Abstract: The present application provides a display panel and an electronic device. The electronic device comprises the display panel. The display panel comprises a gate driving unit, a first auxiliary driving unit and scan lines. The first auxiliary driving unit rapidly pulls down the falling edge of the scan signal transmitted in the scan line to reduce the delay of the falling edge of the scan line. Thus, the number of gate driving units in the display panel can be reduced, thereby reducing the width of the frame of the display panel and the electronic device.
