Abstract: A pixel structure, a display substrate and a display device are disclosed. The pixel structure comprises a plurality of first pixels, second pixels and third pixels. The first pixel comprises a first sub-pixel arranged at upper-right part and a second sub-pixel arranged at lower-left part. The second pixel comprises the second sub-pixel arranged at upper-right part and a third sub-pixel arranged at lower-left part. The third pixel comprises the third sub-pixel arranged at upper-right part and the first sub-pixel arranged at lower-left part. The second pixels are arranged at the right and upper sides of the first pixels. The third pixels are arranged at the right and upper sides of the second pixels. The first pixels are arranged at the right and upper sides of the third pixels.

Abstract: A method and device for detecting a defect of a display panel, the method comprises steps of: connecting at least one electrical test pad on the display panel to a first detecting terminal, and connecting another at least one electrical test pad on the display panel to a second detecting terminal; providing a preset voltage between the first detecting terminal and the second detecting terminal; and, detecting whether magnitudes of currents passing through the first detecting terminal and the second detecting terminal within a predetermined time are less than a preset current threshold, and if not, then determining there is a defect on the display panel. The present disclosure can implement effective detection and interception of a progressive defect or badness in the display panel.

Abstract: The present invention provides a DRM method and system for supporting offline sharing of digital resources. When a client applies for joining in a domain, the client sends its own device information to a server, and obtains feature data of the domain by receiving a sharing certificate sent by the server. Wherein, the sharing certificate is created by encrypting the feature data of the domain by using the equipment information of the client as a cipher. The client decrypts the sharing certificate by using its own equipment information to obtain the feature data. Since the feature data has already been obtained in the procedure of applying for joining the domain, a client is able to use the digital resources by using the feature data even if the client cannot connect to network, thus, an advantage of supporting offline sharing of digital resources is achieved.

Abstract: The present invention provides a server comprising: a selection unit configured to select a target content from each digital file among a plurality of digital files according to a selection instruction received from a terminal; an extraction unit configured to extract privilege information corresponding to the target content from file key information corresponding to each digital file among the plurality of digital files, so as to obtain a plurality of privilege information; an authorization information generation unit configured to generate authorization information according to the plurality of the privilege information; and a processing unit configured to, when an authorization request is received from the terminal, transmit the authorization information to the terminal so that the terminal performs predetermined operations on the target content according to the authorization information. The present invention further provides a terminal and a digital copyright management method.
