Abstract: The present disclosure provides a quantum dot light-emitting diode (QLED) and a preparation method thereof. The QLED includes an anode and a cathode that are oppositely arranged, a quantum dot luminescent layer arranged between the anode and the cathode, and an electron transport layer (ETL) arranged between the quantum dot luminescent layer and the cathode. The ETL includes a first ETL, and the first ETL is a zinc oxide film with a surface hydroxyl content of less than or equal to 0.4. Alternatively, the ETL includes zinc oxide, and at least a part of a surface of the zinc oxide includes an amino ligand and/or a carboxyl ligand with 3 to 7 carbon atoms. In the present application, the QLED improves a service life of a QLED-based device effectively.

Abstract: The present application discloses a QLED and a preparation method thereof. The QLED comprises an anode and a cathode being oppositely arranged, a quantum dot luminescent layer arranged between the anode and cathode, and an ETL arranged between the quantum dot luminescent layer and the cathode. Where the ETL includes a first ETL, and the first ETL is a zinc oxide film with a surface hydroxyl content being greater than or equal to 0.6. Or alternatively, the ETL contains zinc oxide, and the surface of at least some of the zinc oxide contains amino ligands and/or carboxyl ligands with 8-18 carbon atoms. The QLED provided in the present application improves an external quantum efficiency of the QLED device effectively.

Abstract: An image obtaining method includes outputting an image in at least one of multiple image output modes. The multiple image output modes include a full-size mode, a first binning mode, and a second binning mode. In the full-size mode, a first image is obtained according to a first pixel value. In the first binning mode, a second image is obtained according to a second pixel value and a third pixel value. In the second binning mode, a third image is obtained according to a fourth pixel value and a fifth pixel value.

Abstract: Embodiments of the present disclosure provide a method and a device for controlling an electronic device, and a computer-readable storage medium. The method includes: receiving a preset instruction; activating a second camera when controlling a first camera to capture a first image of a first field of view; controlling the second camera to capture a second image of a second field of view, in which the second field of view is different from or not exactly the same with the first field of view; and storing the first image and the second image, and establishing a correspondence between the first image and the second image.

Abstract: The present disclosure provides a control method, a control device and an electronic device. The wide-angle camera is started first. Then, the displayer is controlled to display a cached wide-angle image as a preview image. Next, a designated area is identified and the telephoto camera is started during zooming the preview image. Further, the actuator is controlled such that a cached telephoto image is located in the designated area, and the wide-angle camera and telephoto camera are controlled to image respectively. Finally, the wide-angle image and telephoto image are combined. With the control method and device and the electronic device in the present disclosure, the telephoto camera may image the designated area when the user zooms the designated area of the cached wide-angle image, thereby enhancing sharpness of the designated area and improving the user experience.

Abstract: An image sensor includes a light sensing array, a light filtering array, and a plurality of conversion units. The light sensing array includes a plurality of light sensing units. Each of the light sensing units includes a plurality of light sensing pixels. The light filtering array is disposed on the light sensing array. The light filtering array further includes a plurality of light filtering units. Each of the light filtering units correspondingly covers one of the light sensing units. Each of the conversion units includes at least two source followers. At least one of the at least two source followers is connected to a plurality of the light sensing pixels. A control method configured to control the image sensor and an electronic device including the image sensor are also provided.

Abstract: The present disclosure provides a control method, a control apparatus and an electronic device. The method includes: controlling the displayer to display a cached wide-angle image output by the wide-angle camera as a preview image; processing a user input of the input device to determine whether to zoom the preview image; determining whether a predetermined condition is satisfied during zooming the preview image; starting the telephoto camera and controlling the displayer to display a cached telephoto image output by the telephoto camera as the preview image when the predetermined condition is satisfied. The control method, the control device and the electronic device according to embodiments of the present disclosure may switch between different cameras timely to simulate optical zoom by determining the zoom ratio and the predetermined zooming-in threshold, thereby ensuring the image quality and enhancing the user experience.
