Disclosed are a text boundary processing method, a display panel and a computer-readable storage medium. The method includes: acquiring a grayscale value of each sub-pixel in a display panel; determining a current sub-pixel is a text boundary according to a grayscale value of the current sub-pixel and grayscale values of sub-pixels adjacent to the current sub-pixel; and interchanging grayscale values of a red sub-pixel and a blue sub-pixel in a sub-pixel group where the current sub-pixel is located, where, the sub-pixel group consists of the current sub-pixel and two sub-pixels adjacent to the current sub-pixel in a same row where the current sub-pixel is located.

Described are various embodiments of a digital display device comprising a light filed display operatively coupled thereto, and vision correction system and method user same. In one embodiment, a system and method are provided for implementing a viewer-specific image perception adjustment within a defined view zone (e.g. field of view zone).

An e-paper display device including an e-paper display panel, a graphics library and a display controller is provided. The display controller is coupled to the e-paper display panel. The display controller is configured to receive a line segment input signal and call the graphics library, and then drive, using a set of signal waveforms, the e-paper display panel to display a line segment. The set of signal waveforms is generated according to the line segment input signal and the graphics library. The line segment includes at least one gray level. In addition, a method for driving an e-paper display device is also provided.

A computing device is provided, which includes an input device, a display device, and a processor configured to, at a rendering stage of a rendering pipeline, render visual scene data to a frame buffer, and generate a signed distance field of edges of vector graphic data, and, at a reprojection stage of the rendering pipeline prior to displaying the rendered visual scene, receive post rendering user input via the input device that updates the user perspective, reproject the rendered visual scene data in the frame buffer based on the updated user perspective, reproject data of the signed distance field based on an updated user perspective, evaluate the signed distance field to generate reprojected vector graphic data, and generate a composite image including the reprojected rendered visual scene data and the reprojected graphic data, and display the composite image on the display device.

A method of providing a graphical output may include scanning at least a portion of a user's face using a sensor; generating a depth map using the scan; and determining a similarity score between the depth map and a set of stored biometric identity maps that are associated with a registered user. In response to the similarity score exceeding a threshold, the user may be authenticated as the registered user. The method may further determine a corrective eyewear scenario, select a display profile that is associated with the corrective eyewear scenario, and generate a graphical output in accordance with the selected display profile.

A data processing device, which processes and provides data to a plurality of logical pixels of a display device, includes: a data analysis part which analyzes information of text, color, line or edge in each of the data; and a data compensation part which compensates text data corresponding to a logical pixel which does not express text color among the data having the information of text based on the information analyzed in the data analysis part, where each of the logical pixels of the display device comprises at least one of red, green, blue and optional color sub-pixels.

A system may render glyphs based on stored textures without loss of quality at subpixel scales. The system may determine a content of a pixel of a display corresponds to a glyph, determine a subpixel alignment offset of a specified screen coordinates for the glyph with respect to the pixels of the display, based on the subpixel alignment offset, select one or more versions of the glyph from a plurality of versions of the glyph, a first version of the glyph of the plurality of versions of the glyph having a corresponding first subpixel alignment offset and a second version of the glyph of the plurality of versions of the glyph having a corresponding second subpixel alignment offset, and generate a display version of the pixel based on the selected one or more versions of the glyph and the subpixel alignment offset of the specified screen coordinates.
