Abstract: A processing circuit includes a load unit and a detection circuit, and a proportional relationship exists between a load value of the load unit and a load value of a first pixel line. The load value of the load unit is obtained through the detection circuit, to obtain the load value of the first pixel line. Then, based on the load value of the first pixel line, a drive current circuit is controlled to provide a corresponding drive current to the first pixel line. When the drive current enables a light-emitting diode (LED) on the first pixel line to emit light within drive time, a current value is as small as possible.

Abstract: A display screen adjustment method and apparatus, and a device are provided. A display screen includes a first display area and a second display area, a camera component is disposed under the first display area, and light transmittance of the first display area is higher than light transmittance of the second display area. The adjustment method includes: collecting present ambient illuminance on a terminal; and when the ambient illuminance is lower than an ambient illuminance threshold, adjusting, based on a first ambient light adaptation adjustment curve, luminance corresponding to grayscale 255 of the first display area to first luminance, and adjusting, based on a second ambient light adaptation adjustment curve, luminance corresponding to grayscale 255 of the second display area to second luminance, where the first luminance is approximately equal to the second luminance.

Abstract: A source drive include a power supply circuit that includes a charge pump, a reference source generation circuit, and a low-dropout (LDO) regulator. The charge pump includes at least two on-chip capacitors, is coupled to the reference source generation circuit, and is configured to provide a negative voltage level for the reference source generation circuit based on an external positive voltage power supply. The reference source generation circuit is coupled to the LDO regulator. The reference source generation circuit is configured to provide a reference voltage for the LDO regulator based on the negative voltage level. The LDO regulator is coupled to a load circuit, and the LDO regulator is configured to output a power supply voltage to the load circuit based on the reference voltage and an external negative voltage power supply.

Abstract: This application provides a display panel and an electronic device. A display region of the display panel is divided into at least two pixel regions. The pixel region includes at least two subpixels. The display region includes a first display region and a second display region. Subpixel density of the first display region is less than that of the second display region. In the first display region, at least some adjacent pixel regions have different structures. By changing structures of at least some pixel regions in the first display region, an arrangement rule of structures in pixel regions in the first display region is changed to some extent, and form a long-period diffraction grating or an aperiodic diffraction grating, so that a diffraction phenomenon caused by light passing through the display panel can be mitigated.
