Method and device for blur elimination

Abstract

The invention relates to the technical field of electronic communication, in particular to a method and a device for blur elimination. The method and the device are used for eliminating a blur in a display screen. The method comprises the following steps: determining peripheral pixels capable of generating the blur; and applying voltage to the peripheral pixels, wherein the voltage enables the peripheral pixels to be white or bottom-colored during displaying. When the method is used, voltage applied to charged particles corresponding to the peripheral pixels enables the peripheral pixels to be white, so that when voltage is applied to charged particles corresponding to data to be displayed, although a generated electric field can influence the charged particles corresponding to the peripheral pixels, generation of the blur caused by free movement of the charged particles corresponding to the peripheral pixels, which are influenced by the electric field, can be prevented as corresponding voltage is applied to the charged particles corresponding to the peripheral pixels.

Description

technical field [0001] The present invention relates to the technical field of communication electronics, and in particular, to a method and device for eliminating image sticking. Background technique [0002] With the development of science and technology, electronic paper books have penetrated into people's daily life. Electrophoretic display technology (EPD) is commonly used in electronic paper books to display the corresponding content of the text. The EPD screen consists of many tiny capsules, each of which contains positively charged white charged particles and negatively charged black charged particles, both of which are suspended in a clear liquid. When the negative electric field is set, the white particles move towards the top of the microcapsules and are visible to the reader, where the surface area appears white. At the same time, when a positive electric field is set, the black particles move towards the top of the microcapsules, and the black particles are vi...

And this afterimage will become deeper and deeper as the number of page turning increases. It can be seen that if there is such an afterimage on each page, it will greatly affect the user experience.

[0004] In order to eliminate the above afterimages, it is necessary to use GC16 mode to refresh the screen, but the disadvantage of GC16 mode is that it takes a long time, and the screen will appear black once during the refresh process, which is not very good for user experience, so e-book products usually turn pages Perform a refresh operation in GC16 mode after 10 times to achieve the effect of eliminating afterimages and reducing the number of flickering
