Abstract

The embodiment of the invention discloses a bistable-state display screen refreshing method and device and relates to the field of electronic display, and the method device disclosed by the embodiment of the invention can be used for simultaneously providing a better display effect and a higher refreshing speed. The method comprises the following steps: dividing a display window into a plurality of display areas; defining each display area as one of an Xth picture area, a Yth character area and a Zth undetermined area, wherein X, Y and Z are non-zero natural numbers; when the Zth undetermined area is in the presence and the Zth undetermined area has new content to display, judging whether the content to be displayed in the Zth undetermined area contains pictures; if the content contains pictures, refreshing the Zth undetermined area which contains the new content to be displayed by virtue of the first gray level; and if the content does not contain the pictures, refreshing the Zth undetermined area which contains the new content to be displayed by virtue of the second gray level. The bistable-state display screen refreshing method and device are mainly used for refreshing the bistable-state display screen and are especially used for refreshing an electronic reader.

Description

technical field [0001] The invention relates to the field of electronic display, in particular to a bistable display screen refreshing method and device. Background technique [0002] Eink (Electronic Ink, electronic ink) technology has been increasingly applied to electronic display devices. Compared with LCD (Liquid Crystal Display, liquid crystal display), CRT (Cathode Ray Tube, cathode ray tube) and other display technologies, it has the characteristics of easy readability, flexibility, low cost and low power consumption. Eink has good reflectivity and contrast, it looks like ink on paper, and it can still maintain good contrast under strong light. People feel comfortable reading on a display made of Eink. [0003] At present, Eink has been used to make the display screen of the e-reader, that is, the bistable display screen. The bistable display screen adopts different gray scales for display, such as 16 gray scales or 2 gray scales. [0004] The bistable display ad...
