    Abstract: This application provides a display panel, a preparation method therefor, and a display apparatus. A first display region of the display panel has an OLED pixel, a second display region has a Micro LED pixel, the Micro LED pixel has a light emitting region and a light transmission region, and a camera is disposed below the second display region. After the Micro LED pixel is used in the second display region, display pixels having a same area in the first display region and the second display region can be designed, to implement display effect consistency between the first display region and the second display region. Because a size of the Micro LED pixel for light emitting is small, it can be ensured that the Micro LED pixel has a large light transmission region, so that light transmittance of the second display region can be improved.

    Abstract: Embodiments of this application disclose an intelligent electric appliance and a control method. The intelligent electric appliance includes: a first controller, where the first controller is configured to: receive a first instruction of a user, and convert the first instruction into a second instruction; and a second controller, where the second controller is connected to the first controller by using a communication interface. The first controller is further configured to send the second instruction to the second controller by using the communication interface, where the second controller is configured to control, based on the second instruction, the intelligent electric appliance to run. The first controller is configured to be independently upgraded when the intelligent electric appliance is connected to a network.

    Abstract: The present disclosure relates to display devices and imaging control methods of a display device. One example display device includes a display, a lens assembly, a driver, and a controller. The controller is configured to convert a first image into n consecutive second images, and generate a drive signal used to control the driver to move, where an image resolution of the second image is less than an image resolution of the first image, a refresh rate of the second image is greater than a refresh rate of the first image, and n≥2. The driver is configured to drive, under control of the drive signal, at least one optical element or the display connected to the driver to move to adjust a display location of the second image displayed by the display, so that the n consecutive second images are displayed at n different locations.

    Abstract: The present disclosure relates to displays and imaging methods. One example display includes a self-luminous array, a pixel expansion apparatus, and a lens of an optical engine. The self-luminous array includes a plurality of self-luminous pixels that autonomously emit light. The pixel expansion apparatus includes a driver and a transparent flat plate. A light beam emitted by the self-luminous array is imaged on an imaging plane of the lens of the optical engine through the transparent flat plate. The transparent flat plate is driven by the driver. In some instances, for the display module, in a time dimension, a same unit imaging area can display different colors in a time-division manner, and in a space dimension, a shift of a light beam can be controlled.

    Abstract: A driving method and driving apparatus for a light-emitting diode LED display, and an LED display are provided, to decrease power consumption of the LED display. The driving apparatus includes temperature sensors (201, . . . , 20m), a control unit (301), and a power supply unit (401). The power supply unit (401) is configured to provide driving voltages (VDD, VSS) for light-emitting diodes (1011, 1021) in all pixel circuits (101, . . . , 10n) in the LED display. The temperature sensors (201, . . . , 20m) are configured to collect a first temperature value of the LED display. The control unit (301) is coupled to the power supply unit (401), and is configured to control, based on the first temperature value, the power supply unit (401) to dynamically adjust the driving voltages (VDD, VSS) that are applied to the light-emitting diodes (1011, 1021) in all pixel circuits (101, . . . , 10n).
