Abstract: A touch display panel and a display apparatus are provided. The touch display panel includes: a first substrate, a second substrate, a common electrode layer, a touch electrode layer and a touch electrode wire layer. The common electrode layer is an entire piece of electrode; thus, respective display units may be ensured to have the same common voltage during a display driving, thereby solving the conventional problem of image flicker and non-uniform display of the display panel due to different common voltages in the respective display units caused by different resistances of the block-shaped electrodes in the common electrode layer. Moreover, the touch electrodes in the touch electrode layer are metal grid electrodes. Hence, the resistances of the touch electrodes are reduced and a touch sensitivity of the touch display panel is improved, while a high light transmittance of the touch display panel is ensured.

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.
