Abstract
The present application discloses a display panel and an electronic device. The display panel includes a power access end configured to supply a first power voltage. A driving module is configured to input a second power voltage to a second end of a light-emitting element under a control of a data signal. An equivalent resistance of a driving module of a pixel adjacent to the power access end is greater than an equivalent resistance of a driving module of a pixel away from the power access end.
Claims18
A display panel, comprising:
- a power access end configured to supply a first power voltage;
- and
- a plurality of columns of pixels, wherein each of the columns of pixels comprises a plurality of pixels, and each of the pixels comprises:
- a pixel driving circuit, comprising:
- an input module configured to input a scan signal and a data signal, wherein the data signal is inputted to the first switching element under control of the scan signal;
- and
- a driving module connected to the input module, receiving a second power voltage, and comprising an equivalent resistance and a first switching element, wherein the input module is configured to input the data signal to the driving module under a control of the scan signal;
- and
- a light-emitting element, wherein a first end of the light-emitting element is connected to the first power voltage, a second end of the light-emitting element is connected to the driving module, and the driving module is configured to input the second power voltage to the second end of the light-emitting element under a control of the data signal;
