Abstract

The embodiment of the invention provides an image rolling display method and device, and relates to the technical field of image display. According to the method and the device, a third position coordinate of each to-be-displayed pixel is determined, then a color change parameter of each to-be-displayed pixel is inquired from a pre-established pixel change index table according to the third position coordinate, and finally color updating is carried out on each target pixel according to the pixel change index table. According to the index table of pixels, a judgment is made as to whether each to-be-displayed pixel has color change or not according to the third position coordinate of each to-be-displayed pixel; and if the color change exists, the color of each to-be-displayed pixel is updated according to the pixel change index table, that is, only the color of the pixel of which the color can be changed is updated, so that refreshing of all pixels in a display area is avoided, the occupancy rate of system resources is reduced, and the refreshing efficiency is improved.

Description

technical field [0001] The present invention relates to the technical field of image display, in particular to an image scrolling display method and device. Background technique [0002] In order to improve the dynamic display effect of character strings and improve the utilization rate of the display screen, it is often necessary to scroll and display the character strings on the display screen. A method for scrolling and displaying character strings in the prior art includes setting up a buffer, writing the scrolling displayed character strings into the buffer, reading the character strings from the buffer, and refreshing them to the scrolling display area for display. [0003] In the above method of scrolling and displaying character strings, all pixels in the display area are updated every refresh, and even pixels with no color change need to be refreshed again, which wastes system resources. Contents of the invention [0004] In view of this, the object of the presen...
