Problems solved by technology

The partial refresh of the electronic ink screen is also a partial refresh with a corresponding grayscale transition. When the electronic ink screen needs to display animations with a fast screen change frequency, it will not only process a large amount of data displayed on the screen, but also cause a problem of slow refresh speed. It further affects the display effect of the animation, making it difficult to display the animation normally

Embodiment Construction

[0015] A method for refreshing an electronic ink screen according to the present invention comprises the following steps:

[0016] Add a listener to the renderer of the electronic ink screen to monitor the frame rendering update frequency of all electronic ink; when the update frequency is higher than the threshold, the listener sends a global notification to make the refresh manager use the first partial refresh mode to update the electronic ink screen Refresh: when the update frequency is lower than the threshold, the listener sends a global notification to make the refresh manager use the second partial refresh mode to refresh the electronic ink screen. The threshold for judging whether to switch the refresh mode can be set to 10fps-20fps or even higher. In order to completely eliminate the afterimage effect, the electronic ink screen also sets a global refresh switch. When the global refresh switch is triggered, the refresh manager uses the global refresh mode to globally ...

Abstract

The invention discloses a refreshing method of an electronic ink screen. A monitor is added to a drawing device of the electronic ink screen for monitoring the frame drawing updating frequency of all the electronic ink screen; when the updating frequency is higher than a threshold, the monitor emits a global notification to enable a refreshing manger to refresh the electronic ink screen by use of a refresh mode; and when the updating frequency is lower than a threshold, the monitor emits the global notification to enable the refreshing manager to refresh the electronic ink screen by use of a second refresh mode. Whether two preset refresh modes need to be converted is flexibly determined according to the frame drawing updating frequency of the electronic ink screen in the application process of a user. When a static image is watched for long time, a system determines that replacement of a refreshing mode is unnecessary and an original refreshing mode is always maintained. In case of animations or other images with quite high local refreshing frequencies, the system automatically converts the original refreshing mode into the first refreshing mode, high-frequency refreshing is automatically started, and the influence exerted by a ghost image on reading of the user is reduced.

Description

technical field [0001] The invention relates to a method for refreshing a screen, in particular to a method for refreshing an electronic ink screen. Background technique [0002] The electronic ink screen is composed of many electronic inks, which can be regarded as capsules. Inside each capsule is a liquid charge, where positive charges are colored white and negative charges are colored black. When we give positive and negative voltages on one side, the charged liquid will be attracted and repelled respectively, so that each pixel can display white or black. [0003] Since the refresh of electronic ink is discontinuous, the current graphics can be kept after each refresh, even if the battery is unplugged. To change the displayed content, it is necessary to refresh the screen for a round to display new content. When the screen is not refreshed, the content can be displayed for a long time without additional power, so the battery life of the electronic paper book is based o...
