Abstract: A display apparatus and a driving method therefor. The driving method includes: determining a gaze area and a non-gaze area of a user on a display apparatus in real time (S10); and driving the gaze area for image displaying at a first resolution, and driving the non-gaze area for image displaying at a second resolution, wherein the first resolution is higher than the second resolution. By using of the display apparatus, image resolution can be adjusted according to different areas, so as to realize high-resolution image display in a display area at which a user gazes and realize low-resolution image display in other areas, thereby reducing power consumption and achieving reasonable allocation of resources on the premise of ensuring the user experience.

Abstract: A method and apparatus for constructing a virtual assembly, and a computer-readable storage medium are provided. The method includes: receiving a cutting operation instruction input on a substrate by a user, displaying, on the substrate, a cutting path indicated by the cutting operation instruction, and cutting the substrate into at least two parts, and by means of receiving an assembly instruction input by the user, assembling the at least two parts, and displaying a virtual assembly formed by means of assembly. Since the parts are determined by the cutting path indicated by the cutting operation instruction input by the user, the “parts” in the method are not limited by material or shape, and the virtual assembly formed by assembling the parts is not limited by materials, parts, space, etc. Therefore, the construction of a virtual assembly is highly flexible, thereby improving the user experience.

Abstract: This application discloses an LDPC code-based decoding method and apparatus, and pertains to the field of communications technologies. In this application, n×L LLR values may be decoded based on a target element in a target basis matrix, and a non-target element in the target basis matrix is forbidden to participate in decoding the n×L LLR values. The non-target element is a zero matrix, and the LLR value does not change after the LLR value is processed based on the non-target element. Therefore, the non-target element in the target basis matrix is forbidden to participate in decoding. In this way, decoding of the LLR value is not affected. In addition, a decoding time overhead and an occupied resource are reduced and decoding performance is improved because the LLR value is no longer processed based on a non-target element.
