  • Publication number: 20240282261
    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.

    Abstract: Provided is a heating control method and image forming apparatus. The heating control method includes: when an image forming apparatus is in a printing state, determining a time duration t1 required for the fixing assembly to rise from a current temperature or a temperature at a set moment to a preset target temperature; and determining a time point of the fixing assembly to start heating based on a distance from a preset location to a central position of the fixing assembly, a travelling speed of a printing medium, and the time t1. Through determining the heating time point of the fixing assembly based on the distance from the preset location to the center of the fixing assembly, the traveling speed of the printing medium, and the time duration t1, heating timing of the fixing assembly can be accurately determined, the energy consumption of the fixing assembly can be reduced.
