The invention relates to an auxiliary pixel circuit, a display panel and a display device, and belongs to the field of display. The auxiliary pixel circuit is applied to a display panel with two through holes and located between the two through holes, and the auxiliary pixel circuit comprises a pixel sub-circuit and an auxiliary sub-circuit. The pixel sub-circuit comprises a first transistor, and a control electrode of the first transistor is used for being electrically connected with the first grid line. The auxiliary sub-circuit comprises second transistors, the control electrodes of the second transistors are used for being electrically connected with the first grid lines, the first electrodes of the second transistors are electrically connected with the first electrodes of the corresponding first transistors, the second electrodes of the second transistors are electrically connected with the second electrodes of the corresponding first transistors, and one first transistor corresponds to at least one second transistor. The second transistor consumes the electric quantity transmitted by the first grid line, the total load of the pixel circuit electrically connected with the first grid line is increased, the luminance of the pixel to which the pixel circuit electrically connected with the first grid line belongs is increased, and the problem that the display panel is uneven in display is solved.
Description
technical field [0001] The present disclosure relates to the display field, in particular to an auxiliary pixel circuit, a display panel and a display device. Background technique [0002] Multiple gate (Gate) lines and multiple data (Data) lines are arranged in the display area of the display panel. The plurality of gate lines and the plurality of data lines intersect to define a plurality of pixel areas in the display area. The pixel area is provided with pixel circuits, and the pixel circuits are respectively electrically connected to corresponding gate lines and data lines. [0003] The brightness of the display panel is related to the gate voltage of the driving transistor of the pixel circuit. When the problem of display unevenness (Mura) occurs in the display panel, auxiliary pixel (Dummy Pixel) units will be arranged in the display panel to adjust the voltage of the driving transistor. grid voltage, thereby improving the display uniformity of the display panel. ...
