Problems solved by technology

[0004] Including the two e-paper technologies listed above, as well as e-ink materials such as dichroic dipole twisting balls or dichroic dye liquid crystals, these electronic writing panels must rely on an external electric field in practical applications. In order to achieve writing and erasing technology, there is still room for improvement and improvement in terms of the required low power consumption

Abstract

A method for rewriting a display panel includes the following steps: providing a flexible electronic board with an electronic ink layer sandwiched therein; providing a writing unit that does not have electricity and ink pigments, and placing the writing unit on the electronic The action of writing can be performed by applying pressure on the board, and the electronic board will display the written information at the place where the pressure is applied; a control component is provided, which can output high and low potentials with mutual potential difference through two output terminal groups, so that the electric field It acts positively on the electronic ink layer, thus changing the optical display state of the electronic board; removing the electric field, completes the action of erasing the written information, and the erased part can be pressed again to complete the purpose of rewriting.

Description

technical field [0001] The present invention relates to electronic writing tools, in particular to a method for rewriting a display panel that is written in a pressure-applying manner. Background technique [0002] The current electronic writing tool that can rewrite text and images repeatedly is like the so-called electronic paper. Because it has good resolution, wide viewing angle and high contrast, and does not require additional voltage to maintain the image, it has the advantage of low power consumption. , so it has become a new generation of display technology, and the electronic ink material used in it is its main characteristic technology. [0003] Taking the microcapsule electrophoresis technology researched and developed by MIT and E-ink in the United States as an example, blue insulating liquid and white charged particles are put into transparent microcapsules, and the microcapsules are coated with silicone resin as a binder. Distributed on the transparent electr...
