摘要： This application discloses an image sensor, and relates to the field of electronic technology application. The image sensor includes a color film layer, the color film layer includes a plurality of color film units, the color film unit includes at least one color-determined subunit and at least three transparent subunits, and a color of the color-determined subunit is determined. The color-determined subunit is configured to filter out portion of the received light, and the transparent subunit is configured to allow light to pass through. A ratio of a quantity of the at least one color-determined subunit to a quantity of the plurality of subunits is less than 1/2. Because the transparent subunit can allow light to pass through, and most of light incident to the color film layer can be received by a photodiode, light sensitivity of the image sensor can be effectively increased without increasing an area of the color film layer or increasing a size of the photodiode, thereby implementing miniaturization of the image sensor. This application further discloses a method for obtaining image data from the image sensor and discloses a camera device including the image sensor.

摘要： This application provides an image sensor and an imaging apparatus. The image sensor includes a plurality of pixel units. The plurality of pixel units are divided into a first pixel group (23), a second pixel group (24), a third pixel group (25), and a fourth pixel group (26) that are arranged in an array. The second pixel group (24) and the third pixel group (25) are disposed diagonally. The first pixel group (23) includes first pixel units and a fourth pixel unit. The second pixel group (24) includes second pixel units and a fourth pixel unit. The third pixel group (25) includes second pixel units and a fourth pixel unit. The fourth pixel group (26) includes third pixel units and a fourth pixel unit. The first pixel unit, the second pixel unit, and the third pixel unit are monochrome pixel units that are respectively used to receive lights of different colors. The fourth pixel unit is a white pixel unit that receives a white light. In the foregoing technical solution, a white pixel unit is introduced into each pixel group, and sensitivity of the image sensor is improved by using the white pixel unit. This improves resolution and a signal-to-noise ratio of an image.

摘要： A detector (100) and a mobile terminal are provided. The detector (100) is configured to implement temperature detection. The detector (100) mainly includes a lens (10), a collimator hole (20), and an infrared sensor (30) that are arranged on an optical path. The lens (10) is configured to converge ambient light, and the ambient light includes target area light and another area light. The collimator hole (20) is used to obtain the target area light by screening, and block the another area light. To be specific, the collimator hole (20) is used to screen the incident ambient light, and only the target area light can be irradiated to the infrared sensor (30). The infrared sensor (30) is configured to receive the target area light and block the another area light. A convergence function of the lens (10) enables the detector (100) to detect a body temperature at a relatively long distance, and a target area is selected through the provided collimator hole (20). This improves detection accuracy. In addition, the collimator hole (20) is used as a structure for screening light. This can decrease a volume of the detector (100), facilitating miniaturization of the detector (100).

摘要： Embodiments of this application disclose a hybrid bonding structure and a hybrid bonding method. The hybrid bonding structure includes a first chip and a second chip. A surface of the first chip includes a first insulation dielectric and a first metal, and there is a first gap area between the first metal and the first insulation dielectric. A surface of the second chip includes a second insulation dielectric and a second metal. A surface of the first metal is higher than a surface of the first insulation dielectric. Metallic bonding is formed after the first metal is in contact with the second metal, and the first metal is longitudinally and transversely deformed in the first gap area. Insulation dielectric bonding is formed after the first insulation dielectric is in contact with the second insulation dielectric. In the embodiments of this application, the first gap area is disposed to ensure that the first metal may be longitudinally deformed and transversely deformed at the same time. This may avoid a metallic bonding defect and a dielectric bonding defect, and improve a yield rate of mass production and long-term reliability of a device.

摘要： This application provides a display panel, a display apparatus, and a preparation method for a display panel. The display panel includes a plurality of pixel units, and each pixel unit includes at least three color subpixels. All subpixels of the pixel unit are packaged into one pixel unit by a passivation layer. Packaging and a transfer at the passivation layer are performed per pixel unit. Compared with transferring a single subpixel, this greatly reduces a quantity of pixel transfers, and reduces a probability of product damage in a transfer process, thereby helping improve manufacturing efficiency and a product yield. In addition, all subpixels of each pixel unit may share one electrode, to be specific, one ends of the subpixels of the pixel unit each are connected to one first electrode, and the other ends of the subpixels of the pixel unit share one second electrode. This can reduce a total quantity of electrodes of the display panel, reduce a quantity of electrodes that need to be welded when the pixel unit is transferred to a substrate with a drive circuit, improve process efficiency, and also improve a yield of the display panel.

According to this solution, a target image with sharp colors may be obtained in a low-illumination scenario, and a source of the target image is determined based on a single original image of a single image sensor. This is easy for implementation.
