Image displaying method of electronic paper screen

Abstract

An image display method of an electronic paper screen comprises the following steps that: image display resolution is set at first; a display image update event is added and image display update is driven by the event; a to-be-displayed image is cut down; compression storage of the image is carried out, and only the pixel average value of the featured rows and columns of the image is stored; similarity measurement of the to-be-displayed image and a current displayed image is carried out; according to the compared result of image similarity, the display mode of the electronic paper screen is set; human eye visual effect processing of the to-be-displayed image is carried out to display the image. The method extends the application of the electronic paper screen into the intelligent operating system field, and is easy to be transplanted to various advanced embedded type operating systems; meanwhile, the method effectively reduces the phenomena such as afterimage and screen blinking on the electronic paper screen, and saves the power consumption of an electronic paper system; moreover, the method increases the display response time of the electronic paper screen and provides a feasible method for the further application of the relevant fields of electronic paper.

Description

technical field [0001] The invention relates to an image display method on an electronic product device using an intelligent operating system and an electronic paper display screen as a display output. Background technique [0002] With the continuous surge of global paper consumption, the living environment of human beings is being destroyed unprecedentedly. People put forward the idea of ​​using new materials to replace traditional paper out of the protection of forests and the environment. In recent years, a paper-like flexible and thin rewritable display called electronic paper has attracted more and more attention. This kind of flexible and thin electronic paper screen can maintain the display of images in the state of no power supply. Electronic paper is an electronic device specially used for reading. It has high contrast, clear text, supports screen handwriting, consumes very little power, and can be gently bent. The electronic paper screen can erase or rewrite the ...

Problems solved by technology

[0003] It is precisely because of the above-mentioned advantages of electronic paper displays that a large number of electronic products using electronic paper as display screens have appeared on the market. However, existing electronic paper products have considerable limitations. Currently, electronic paper display systems mainly use Customized Linux and some self-developed operating systems. Such electronic products have simple screen menus, single functions, and little content, which is difficult to satisfy. E-paper product menu customization is characterized by personalization, intelligence, aesthetics, and rich functions.

The emergence of intelligent operating systems meets people's needs for electronic paper products, but at present, electronic paper products based on intelligent operating systems generally have defects in display methods, such as image afterimages, screen flickering, etc.
