Information display method, reader and computer storage medium

Abstract

The invention discloses an information display method, a reader and a computer storage medium, and the method comprises the steps: detecting handwriting report point data generated by handwriting operation; modifying the interface image stored in the display cache according to the handwritten report point data, so that the display cache synchronizes the modified interface image to an ink screen for display; updating handwriting content drawn on the handwriting layer in a system cache according to the handwriting report point data, and performing layer synthesis processing on the updated handwriting layer and a plurality of to-be-displayed interface layers after each time of updating to obtain a projection screen image through synthesis; and sending the screen projection image to the screenprojection equipment, so that the screen projection equipment displays the screen projection image. According to the scheme of the invention, the interface image and the screen projection image are obtained by modifying the image and synthesizing the image layer, so that the handwriting response speed can be ensured, and the real-time screen projection of the handwriting content can be realized.

Description

technical field [0001] The present invention relates to the field of computer technology, in particular to an information display method, a reader and a computer storage medium. Background technique [0002] An ink screen reading device refers to an electronic reading device using an electronic ink screen (E-ink or Electronic Paper Display / EPD). Among them, the electronic ink screen is a screen that does not emit light itself but relies on external reflection to achieve a display effect. Its display effect is very similar to that of paper materials, so it can be compared to the experience of reading paper materials. The electronic ink screen is composed of many microcapsules, and each microcapsule contains a plurality of black particles and a plurality of white particles, both of which are oppositely charged. When black content needs to be displayed on the screen, the black particles are driven by voltage to move up to the top of the screen (that is, to move from the bottom...

Problems solved by technology

[0004] However, in the existing handwriting sharing solutions, usually only after the writing of the handwriting is completed, the content of the written handwriting can be transmitted to other devices for viewing in other devices. The real-time performance of this sharing solution is poor
