    Abstract: A TFT-driven display device includes an upper substrate and a lower substrate facing each other, multiple TFTs disposed on a side of the lower substrate facing the upper substrate, and a metal layer disposed on a side of the upper substrate facing to the lower substrate. The metal layer includes a portion that does not overlap with the active layer of the TFTs in a light transmission direction, or the metal layer includes portions overlapping with the active layer of the TFTs in the light transmission direction, the overlapping portions have a pattern width less than a pattern width of other portions that do not overlap with the active layer. In the TFT-driven display device, a photo leakage current caused by the light reflected by the metal may be reduced, because no portion of the metal layer is provided in the position opposed to the active layer of the TFTs located on a TFT array substrate.

    Abstract: A method for driving a display panel and a display apparatus are provided. The display panel includes a display region including a fingerprint recognition region and includes subpixels located in the display region, and the subpixels include first subpixels located in the fingerprint recognition region and used as a light source for fingerprint recognition. In a first mode, the subpixels are scanned at a first frequency, and in the second mode, the subpixels are scanned at a second frequency. The second frequency is greater than the first frequency. The method includes: when the display panel is in the first mode, monitoring whether the display panel receives a fingerprint recognition requirement, and if yes, controlling the display panel to enter a trigger state; and when the display panel is in the trigger state, scanning the first subpixels at a frequency greater than the first frequency.

    Abstract: The disclosure discloses a pixel circuit, a method for driving the same, a display panel and a display device, which utilize a first initialization module, a data writing module, a threshold compensation module. Besides, since the pixel circuit is further provided with a second initialization module and the second initialization module is configured to enable a signal of a first voltage terminal to flow through the driving transistor before a light emitting device emits light, after the pixel circuit displays a low-grayscale image and before the pixel circuit displays a high-grayscale image, a large current is enabled to flow through the driving transistor to compensate for a threshold voltage hysteresis effect of the driving transistor, thereby improving the problem that the brightness of a first frame is low after an existing pixel circuit has switched from displaying a low-grayscale image to displaying a high-grayscale image.
