Abstract: The present invention provides a display panel and a mobile terminal. The display panel comprises a substrate and multiple barrier units spaced apart from each other in a peripheral area, an opening defined between each two adjacent barrier units, and a first array encapsulation unit and a second array encapsulation unit separate from each other. End surfaces of each barrier unit have different areas. By using the barrier units with upper and lower end surfaces of different areas, encapsulation films are broken in the openings when the encapsulation films are formed. Therefore, the present invention prevents cracks extension.

Abstract: The present application provides a display panel and a display device. An N-th auxiliary unit is arranged in a display area of the display panel. An output end of the N-th auxiliary unit is connected to an N-th scan line. By connecting the auxiliary unit arranged in the display area to the corresponding scan line, a falling edge of a scan signal transmitted in the scan line can have sharp falling or a rising edge of the scan signal can have sharp rising, which can alleviate a signal distortion problem caused by transmission delay in the display area.

Abstract: An array substrate and a liquid crystal display panel are provided. By arranging scan lines on a second metal layer in the array substrate, a width of a channel of a thin-film transistor is not related to a width of a scan line, so that the width of the scan line can be increased to reduce resistance of the scan line. In addition, the impedance of the second metal layer is relatively small, so that the impedance of the scan line can be reduced. Furthermore, a channel width of the thin-film transistor is relatively small, which improves charging efficiency of the array substrate and reduces the distortion difference of scan signals.
