Abstract

The embodiment of the invention discloses an ink screen graffiti refreshing method and device. According to the technical scheme, in the graffiti mode, picture refreshing is forbidden, the graffiti area is obtained, and the graffiti area comprises the graffiti track; detecting whether a first type of pixel points exist in the graffiti area or not, wherein the first type of pixel points comprise pixel points except pure black pixel points and pure white pixel points; and if the graffiti track exists in the page before the graffiti track is scrawled, continuing to keep forbidding picture refreshing, and when a refreshing instruction is received, releasing forbidding picture refreshing and refreshing the whole page of picture at the same time so as to superpose the graffiti track to the page before the graffiti track According to the embodiment of the invention, the problem of flicker in graffiti refreshing can be solved, and the user experience is improved.

Description

technical field [0001] The embodiments of the present application relate to the technical field of electronic ink screens, and in particular, to a method and device for refreshing graffiti on an ink screen. Background technique [0002] In recent years, as display devices have gradually begun to develop in the direction of lightness and thinness, the ink screen display device has become a display device that meets the needs of the public. Ink screen display devices have been widely used in e-readers (eg, e-books or e-newspapers) or other electronic components (eg, e-tags) due to their advantages of being light, thin, durable, and energy-saving, environmentally friendly, and low in power consumption. [0003] When the existing electronic ink screen is in graffiti mode, it performs partial refresh when the graffiti is completed and the pen is lifted. When there are neither pure black pixels nor pure white pixels, there will be flickering in the partial refresh, and the user ex...
