Abstract: A display substrate includes a pixel driving circuit, which includes a driving circuit, a storage circuit and a reset circuit. The reset circuit is electrically connected to a first terminal of the driving circuit. The driving circuit is used to conduct a path between the first terminal and a second terminal of the driving circuit under the control of a potential at its control terminal. The storage circuit is electrically connected to the control terminal of the driving circuit. The reset circuit includes a first capacitor. The storage circuit includes a second capacitor. An area of an overlap between orthographic projections of a first electrode plate and a second electrode plate of the first capacitor on the base substrate is smaller than that of the second capacitor on the base substrate.

Abstract: A display substrate and a display device are provided, the display substrate includes: a substrate, and a power source layer, a conductive layer, and a cathode layer sequentially stacked on the substrate in a direction away from the substrate; the conductive layer includes first conductive patterns and second conductive patterns insulated from each other, the first conductive patterns are coupled to the power source layer, and the second conductive patterns are coupled to the cathode layer.

Abstract: A shift register circuit includes a first control sub-circuit and a first output sub-circuit. The first control sub-circuit is configured to: adjust a voltage of a first node to a turn-on voltage due to an influence of a first direct current voltage signal from a first clock signal terminal, an initial voltage signal from an initial signal terminal and a second direct current voltage signal from a second clock signal terminal; and maintain the voltage of the first node at the turn-on voltage due to an influence of a first clock signal from the first clock signal terminal and a second clock signal from the second clock signal terminal. The first output sub-circuit is configured to be turned on under a control of the turn-on voltage of the first node to transmit a first voltage signal from a first voltage terminal to a signal output terminal.

Abstract: Disclosed are a method for querying information of a TV program broadcasted currently and a smart TV, to solve the problem that the descriptive information of a TV program broadcasted currently displayed by the smart TV doesn't match the actual video image broadcasted. The method comprises: obtaining a program information list corresponding to a channel identification from an EPG server according to the channel identification of a channel broadcasted currently, where the program information list includes correspondence between program identifications and program descriptive information; after obtaining a real time video stream from a program source server corresponding to the channel identification, parsing and obtaining a program identification in the real-time video stream; and obtaining program descriptive information corresponding to the program identification from the correspondence.

Abstract: The present disclosure provides a method for playing an audio/video and a display device. The method for playing the audio/video of the present disclosure includes: downloading an audio/video clip in an audio/video to be played when a preceding-playing-page corresponding to the audio/video to be played is opened; the preceding-playing-page is any one page located before a playing page corresponding to the audio/video to be played; and playing the audio/video clip when the playing page is opened. The present disclosure can obtain the audio/video clip in the audio/video to be played through the connection to the network without on the playing page, thereby saving the playing start time, possessing a fast playing start speed and a short playing start time, and enhancing the user's experience.
