Abstract

The invention discloses an ink screen quick refreshing method, and the method comprises the steps: obtaining a current frame of image corresponding to a screen refreshing instruction and a previous frame of image and a next frame of image corresponding to the current frame of image when the screen refreshing instruction is received; performing absolute difference calculation on the current frame of picture, the previous frame of picture and the next frame of picture to obtain a first difference picture and a second difference picture, and determining a first pixel point in the first differencepicture and a second pixel point in the second difference picture; and if the first pixel point does not coincide with the second pixel point, executing refreshing operation on the second pixel pointafter the first pixel point is refreshed. The invention further discloses an ink screen quick refreshing device and equipment and a computer readable storage medium. By simplifying the refreshing process of the electronic ink screen, the refreshing speed of the electronic ink screen is increased.

Description

technical field

[0001] The invention relates to the field of ink screen display, in particular to a fast refresh method, device, equipment and computer-readable storage medium for an ink screen. Background technique

[0002] Currently known devices with electronic ink screens, such as e-books, have relatively complex operating system application display processes, which makes it difficult to refresh the display screens desired by users at the highest possible frame rate at an accurate timing, and The quick refresh of the handwriting of external devices (such as electromagnetic stylus) and the automatic refresh of the electronic ink screen are mutually exclusive. At present, there is no way to optimize this mutually exclusive part, and the writing effect of the stylus that can currently be provided is consistent with the actual use of the application. The handwriting effects are not uniform. Contents of the invention

[0003] The main purpose of the present invention is to...
