Abstract
A display panel includes light-emitting devices and pixel circuits. The pixel circuit includes a driving module, a data writing module, and a light-emitting control module. In an embodiment, the pixel circuit comprises first working modes and second working modes. In an embodiment, the data writing module transmits different data voltages to the driving module in at least two of the first working modes. The data writing module transmits a same data voltage to the driving module in any one of the second working modes. Durations taken by the light-emitting control module to control the driving module to transmit a driving current to the light-emitting device in any one of the first working modes are the same. Durations taken by the light-emitting control module to control the driving module to transmit a driving current to the light-emitting device in at least two of the second working modes are different.
