Abstract: The present disclosure provides a display panel and a mask. The display panel does not dispose a common electrode layer in a transparent area and an aisle area, and by this way, after the transparent area of the display panel is cut to form a through-hole, the common electrode layer can still be protected by other film layers and not be directly exposed to air, thereby preventing intrusion of water and oxygen.

Abstract: The present disclosure relates to a pixel driving circuit having a pixel structure of 7T1C to compensate a threshold voltage of a driving thin film transistor (TFT) in the organic light-emitting diode (OLED). As such, the current passing through the OLED may not be related to the threshold voltage of the driving TFT. Thus, the improper image-displaying of the OLED display caused by the drifting of the threshold voltage of the driving TFT may be reduced.

Abstract: The present disclosure provides a TFT array substrate and an OLED display panel. The TFT array substrate includes a display area, a non-display area around the display area, a COF bonding area and a test area. The COF bonding area and the test area are arranged in the non-display area. The test area includes several test pads spaced apart. According to the present disclosure, the test pads are arranged on the TFT array substrate. Thus, during testing, it is not necessary to cut off the connection wire between the test pads and the TFT array substrate. Therefore, the problem of uncovered metal residue after the cut-off of the connection wire may be avoided. Moreover, when the test of the TFT array substrate is finished, the test pads will be covered by insulating material such that the problem of uncovered metal residue of the test pads can be avoided.
