Embodiment Construction

[0038] It should be understood that the specific embodiments described here are only used to explain the present invention, not to limit the present invention.

[0039] In the prior art, in the GC16 mode, due to the slow refresh rate, the displayed images, videos, etc. will not be displayed smoothly, and the animation effect will be very poor.

[0040] In order to solve the above problems, the present invention proposes a display control method and device based on an electronic ink screen. When the content to be displayed includes pictures and / or videos, and the electronic ink screen is not in the 2-level grayscale refresh mode, control the The electronic ink screen switches to the 2-level grayscale refresh mode, and performs Dither processing on each frame of the picture and / or video to obtain a 2-level grayscale image of each frame of the picture and / or video and refresh the display.

[0041] Further, in the present invention, the pictures and / or videos are displayed by auto...

Abstract

The invention discloses a display control method based on an electronic ink screen. The method comprises the following steps: if detecting that content to be displayed comprises a picture and / or a video, judging whether the electronic ink screen is in a 2-level gray scale refreshing mode; if not, controlling the electronic ink screen to be switched in the 2-level gray scale refreshing mode; and carrying out Dither processing on each frame of the picture and / or the video to obtain a 2-level gray scale image of each frame of the picture and / or the video and carrying out refresh display. The invention also discloses a display control device based on the electronic ink screen. Since the refreshing speed of the 2-level gray scale refreshing mode is fast, each frame of the picture and / or the video obtained after Dither processing can be refreshed and displayed quickly, a smooth display effect can be achieved, and the animation effect is good; and through the Dither processing mode, a certain multi-level gray scale image visual effect can be kept under the A2 refreshing mode.

Description

technical field [0001] The present invention relates to the technical field of electronic paper display, in particular to a display control method and device based on an electronic ink screen. Background technique [0002] At present, the display screens applied to terminals mainly include LCD, LED, and electronic ink (Electronic Ink, EInk) screens. Compared with other display technologies, it is easy to read, flexible, cheap and low power consumption. EInk has good reflectivity and contrast, it looks like ink on paper, and under strong light, it can still maintain good contrast, and people feel comfortable when using Eink screen for reading. [0003] The commonly used refresh mode of EInk screen is GC16 (4bit, Gray Scale) refresh mode. In GC16 refresh mode, 16 gray levels are used for display. [0004] Among them, in the GC16 refresh mode, the refresh speed is slow, and each frame takes about 600ms. In this way, when displaying some pictures such as pictures or videos, du...
