Problems solved by technology

However, since the cover plate is scanned during processing, the arc of the obtained cover plate is not a standard arc, which makes the light RGB ratio change after the light is refracted at the arc of the cover plate. A rainbow pattern is generated at the radian, which affects the user's experience

Embodiment Construction

[0023] The following will clearly and completely describe the technical solutions in the embodiments of the present invention with reference to the accompanying drawings in the embodiments of the present invention. Obviously, the described embodiments are some of the embodiments of the present invention, but not all of them. Based on the embodiments of the present invention, all other embodiments obtained by persons of ordinary skill in the art without making creative efforts belong to the protection scope of the present invention.

[0024] An embodiment of the present invention provides a pixel processing method. The method is applied to a terminal device. Specifically, it is applied to the gray scale brightness corresponding to each sub-pixel in the pixel arrangement on the display screen of the terminal device before the terminal device leaves the factory. Calibrate to eliminate the rainbow pattern that appears at the curved edge of the display screen of the terminal device,...

Abstract

The embodiment of the invention discloses a pixel processing method and device. The method includes: acquiring a mapping table between pixels at a defect positions in a display screen image captured when a display screen is in an operating state and preset standard pixels, wherein the rows of the mapping table represent the sub-pixels of respective pixels in the rows of pixels, the columns of themapping table represent the sub-pixels of respective pixels in the columns of the pixels, and each element in the mapping table represents a comparison result indicative of the size of the sub-pixel at the position corresponding to the row and column corresponding to the element and the size of the standard sub-pixel at the position; and according to the mapping table, calibrating the grayscale brightness corresponding to the sub-pixel of each pixel in the display screen. The pixel processing method and device eliminate rainbow stripes appearing at the arc edge of the cover plate of the display screen, and improve user experience when a user views the display screen.

Description

technical field [0001] The present invention relates to the field of display technology, in particular to a pixel processing method and device. Background technique [0002] With the development of electronic technology, terminals such as mobile phones and tablet computers have developed rapidly. In order to make terminal equipment more beautiful, the industry has begun to pursue thinner and lighter terminal equipment and high screen-to-body ratio of terminals. [0003] At present, the industry has used the refraction principle of the upper cover of the terminal to enlarge the display area seen by the user, so as to achieve a visually borderless effect. However, since the cover plate is scanned during processing, the arc of the obtained cover plate is not a standard arc, which makes the light RGB ratio change after the light is refracted at the arc of the cover plate. A rainbow pattern is generated at the radian of the arc, which affects the user's experience. [0004] The...
