Abstract: A display substrate includes an underlaying substrate, a display structure layer arranged on the underlaying substrate, and a light regulation layer arranged at a light exiting side of the display structure layer. The display structure layer includes multiple sub-pixels. An orthographic projection of the light regulation layer on the underlaying substrate does not overlap with opening regions of the multiple sub-pixels. The light regulation layer is configured to adjust an emergent direction of light of at least one color emitted from the display structure layer.

Abstract: The present disclosure discloses a method for vector reading-writing, a vector-register system, a device and a medium. When a vector-writing instruction is obtained, by using a vector-register controller, a to-be-written-vector address space is converted into a to-be-written-vector-register-file bit address, and, for a nonstandard vector, by using a nonstandard-vector converting unit, after the nonstandard vector is converted into a to-be-written nonstandard vector, and, subsequently, writing is performed, to realize the saving of vector data of any format. When a vector-reading instruction is obtained, by using the vector-register controller, according to the to-be-read width and the to-be-read length, after the to-be-read-vector address space is converted into a to-be-read-vector-register-file bit address, and, subsequently, reading is performed, to realize the reading of vector data of any format.

Abstract: Example methods and systems to implement an economic printing mode are described. In one example, a computer system may provide a user interface specifying multiple selectable levels associated with economic printing mode. The source printing content may be transformed to generate target printing content that is printable using a lower ink consumption compared to the source printing content. For example, in response to a selection of a first level, print quality may be reduced. In response to a selection of a second level, image information in the source printing content may be modified. In response to a selection of a third level, font information associated with textual information in the source printing content may be modified. The computer system may provide the target printing content that includes modified font information to the printer for printing and/or generate a preview of the target printing content prior to printing using the printer.

Abstract: Example methods and systems to implement an economic printing mode with font information modification are described. In one example, a computer system may obtain source printing content associated with a print job that is destined for a printer and the economic printing mode may be selected for the print job. The computer system may extract, from the source printing content, (a) textual information to be printed and (b) font information associated with the textual information. The source printing content may be transformed to generate target printing content that is printable using a lower ink consumption compared to the source printing content by modifying the font information associated with the textual information. The computer system may provide the target printing content that includes modified font information to the printer for printing and/or generate a preview of the target printing content prior to printing using the printer.

Abstract: Example methods and systems for printing ink consumption estimation are described. In one example, a computer system may obtain printing content associated with a document that is printable using a printer. Based on the printing content, the computer system may generate an image representation of the document, wherein the image representation includes an array of multiple pixels associated with first color information from a first color space. Color conversion may be performed by converting (a) the first color information from the first color space to (b) second color information from a second color space associated with the printer. The computer system may estimate an amount of printing ink required for printing the document based on the second color information and provide the estimated amount of printing ink to a user via a user interface.
