The invention provides a pixel circuit, a manufacturing method thereof and a display device. The pixel circuit comprises a plurality of VDD signal lines and at least one bridging structure, the bridging structure is used for electrically connecting two adjacent VDD signal lines. The two adjacent VDD signal lines are respectively a first VDD signal line and a second VDD signal line; the bridging structure comprises four conductive parts which are arranged at intervals and two connecting conductors; the four conductive parts comprise two first conductive parts and two second conductive parts; the two connecting conductors comprise a first connecting conductor and a second connecting conductor which are arranged in an insulating manner, wherein the two first conductive parts are electricallyconnected with the first VDD signal line respectively, the two second conductive parts are electrically connected with the second VDD signal line respectively, the first connecting conductors are connected with one first conductive part and one second conductive part respectively, and the second connecting conductors are connected with the other first conductive part and the other second conductive part respectively. The pixel circuit is provided with a bridging structure, and the problem that a chip cannot correctly control the pixel circuit due to different pixel arrangement modes in the prior art can be solved.
Description
technical field [0001] The present application relates to the display field, in particular, to a pixel circuit, a manufacturing method thereof, and a display device. Background technique [0002] OLED and QLED displays are more and more used in the display field due to their advantages of fast response, wide viewing angle and easy realization of large size. [0003] The 2T1C pixel circuit in the prior art includes two drive transistors, a capacitor, and a light-emitting diode (the light-emitting diode can be a QLED). The pixel circuit also includes two control units, one is a data writing unit, including a scanning Line and data line control, the other is a light-emitting unit, including ELVDD light-emitting control line and ELVSS control. The above two control units are controlled by IC circuit. [0004] For different display devices, the arrangement of pixels is different, and the corresponding pixel circuit can be adjusted in the production process according to the arra...
