Problems solved by technology
[0003] At present, the pixel units in the display panel are usually driven by the pixel circuit to emit light, and the pixel circuit often includes a large number of signal lines, and a large number of signal lines require a large wiring space, which reduces the area for arranging the pixel units on the array substrate. Small, which in turn leads to a limited number of pixel units on the array substrate, which is not conducive to the design and manufacture of ultra-high-resolution display panels

The invention relates to a pixel circuit, a driving method of the pixel circuit, a display panel and a driving method of the display panel. The pixel circuit comprises a driving sub-circuit, a signalinput end, a writing sub-circuit, a first light-emitting control sub-circuit and an energy storage sub-circuit. The signal input end is used for outputting a data signal and a first power supply signal; the write-in sub-circuit is respectively connected with a first scanning signal end, the signal input end and the driving sub-circuit, and is used for providing the data signal to the driving sub-circuit under the control of the first scanning signal; the first light-emitting control sub-circuit is respectively connected with a light-emitting control signal end, the signal input end and the driving sub-circuit, and is used for providing the first power supply signal to the driving sub-circuit under the driving of a light-emitting control signal; and the energy storage sub-circuit is connected to the driving sub-circuit, and the driving sub-circuit writes the data signal into the energy storage sub-circuit in a scanning stage and generates a driving current in a light emitting stage.
Description
technical field [0001] The present disclosure relates to the field of display technology, in particular, to a pixel circuit and a driving method thereof, a display panel and a driving method thereof. Background technique [0002] With the development of OLED (Organic Light Emitting Diode, Organic Light Emitting Diode) display technology, the resolution requirements of OLED display panels are getting higher and higher. Resolution refers to the number of pixel units per unit area, that is, the The number of pixel units is required to be larger and larger. [0003] At present, the pixel units in the display panel are usually driven by the pixel circuit to emit light, and the pixel circuit often includes a large number of signal lines, and a large number of signal lines require a large wiring space, which reduces the area for arranging the pixel units on the array substrate. Small size leads to a limited number of pixel units on the array substrate, which is not conducive to th...
