6 results about "Subpixel rendering" patented technology

The display method and display device for improving line sharpness are provided, the line is a red line in a red and black interval line or a blue line in a blue and black interval line, the display method comprises the following steps: obtaining a to-be-displayed original image of a display screen, the display screen is an active matrix organic light emitting diode display screen in which sub-pixels are arranged in a diamond arrangement manner; when performing sub-pixel rendering processing on the to-be-displayed original image, mapping a pixel in the line in the to-be-displayed original image to a sub-pixel with the same color as the pixel in a corresponding range of the pixel on the display screen, and configuring a non-zero pixel value for other sub-pixels in the corresponding range; and displaying sub-pixel data obtained after the to-be-displayed original image is subjected to the sub-pixel rendering processing through the display screen. The display method and display device can solve the problem that a red and black interval line or a blue and black interval line is not sharp enough when displayed on an AMOLED display screen arranged in a diamond arrangement manner.

This application discloses an image data processing method, apparatus, and electronic device, belonging to the field of image data processing technology. The method is applicable to an electronic device, which includes a first processing unit, a second processing unit, a display driving unit, and a display screen. The second processing unit is connected to the display screen sequentially via the first processing unit and the display driving unit. The first processing unit includes a sub-pixel rendering module. The method includes: when the image enhancement function of the first processing unit is enabled, determining the image enhancement processing method for the first image data based on the format of the first image data output by the second processing unit; performing image enhancement processing on the first image data according to the image enhancement processing method; performing sub-pixel rendering processing through the sub-pixel rendering module; and outputting second image data on the display screen that matches the sub-pixel arrangement of the display screen through the display driving unit.

This disclosure provides a pixel display method and related apparatus. The pixel display method includes: acquiring an original image to be displayed on a display screen, wherein the display screen is an active matrix organic light-emitting diode display screen with subpixels arranged in a diamond pattern and green subpixels on the display screen correspond one-to-one with pixels in the original image; during subpixel rendering processing of the original image to be displayed, mapping the green components of white pixels in the original image to the corresponding green subpixels and surrounding green subpixels on the display screen according to the green tint characteristic of the display screen; and displaying the subpixel data obtained after subpixel rendering processing of the original image to be displayed through the display screen. This disclosure can solve the green tint problem when alternating black and white lines are displayed on an AMOLED display screen with subpixels arranged in a diamond pattern.

The application discloses an image processing method and device. In an edge image of an original image, an original image edge pixel position coordinate of a first pixel block occupied by an image edge is determined; in an enlarged image of the edge image, a new image edge pixel position coordinate of a second pixel block occupied by an enlarged image edge corresponding to the first pixel block is calculated; a new edge slope of the enlarged image edge in the enlarged image is calculated; a gray value of the second pixel block corresponding to the new image edge pixel position coordinate is calculated according to the new edge slope and the new image edge pixel position coordinate; and a sub-pixel rendering is performed on surrounding pixel blocks along the enlarged image edge. The technical scheme of the application can be used in image enlargement and character display enlargement processes, and can effectively reduce the sawtooth problem of a result image and smooth the image region edge.
