Abstract: A display panel and a display device are disclosed, relating to the display technical field. The display panel comprises a display layer and a light control layer which are laminated, the light control layer comprises a plurality of light control pixel areas, the light control pixel areas comprise a thin film transistor, the display layer comprises a plurality of display pixel areas, and the display pixel areas comprise a green sub-pixel; the orthographic projection of the green sub-pixel on the light control pixel area is close to the area where the thin film transistor is located.

Abstract: Items within an item universe or item repository can be associated with subscription options. A subscription visualization user interface can allow a user to visualize subscription costs over a particular time window and within certain display time periods so that better cost transparency can be achieved. Cost transparency and cost containment can be extremely important in an era of increasing subscription sales.

Abstract: A method for printing stock anti-counterfeiting by using a feature image and a corresponding system is disclosed. The method comprises obtaining a feature code for identifying a printing stock by recognizing a first feature of the feature image printed on the printing stock; searching for pre-recorded first anti-counterfeiting information of the printing stock; obtaining second anti-counterfeiting information of the printing stock by recognizing a second feature of the feature image printed on the printing stock; and comparing whether a similarity between the second anti-counterfeiting information and the first anti-counterfeiting information reaches a first match threshold value to determine whether the printing stock is true or false. The first anti-counterfeiting information is embodied as a distinguishable material feature of the printing stock in a feature image region or features of color, shape and position of the image printed in the feature image region.

Abstract: The present disclosure relates to a method for printing stock anti-counterfeiting by using a feature image and a corresponding system, wherein the above method comprises obtaining a feature code for identifying a printing stock by recognizing a first feature of the feature image printed on the printing stock; correspondingly searching for pre-recorded first anti-counterfeiting information of the printing stock in a database by using the feature code; obtaining second anti-counterfeiting information of the printing stock by recognizing a second feature of the feature image printed on the printing stock; and comparing whether a similarity between the second anti-counterfeiting information and the first anti-counterfeiting information reaches a first match threshold value through a manual comparing method or an intelligent device comparing method, wherein if the similarity is higher than the first match threshold value, the printing stock is true, else if the similarity is lower than the first match threshold va

Abstract: The invention relates to a method and apparatus for sending an information code via an audio signal and retrieving an information code. The method of sending an information code via an audio signal includes the steps of: modulating the information code and a sync header into the audio signal in a second band; and transmitting the modulated audio signal in the second band directly, or superimposing and then transmitting the modulated audio signal in the second band with an audio signal in a first band, wherein the first band is different from the second band.
