Abstract

The invention discloses an electronic blackboard and an imaging pen, belonging to the technical field of information display. The electronic blackboard includes: a lower electrode plate, an electrode capsule layer, an upper electrode plate, a frame and a power supply module. The upper electrode plate is provided with a plurality of dividing grooves, and the dividing grooves divide the upper electrode plate into a plurality of sub-units, and the sub-units are evenly distributed. Coated with a transparent conductive film, the electrode capsule layer includes microcapsules, and the microcapsules include white positively charged particles, black negatively charged particles, and colored liquid. The invention provides negative charge to the transparent conductive film of the subunit on the upper plate of the electronic blackboard through the imaging pen capable of tip discharge, so as to change the electric field between the upper and lower plates, so as to directly control the imaging of the electrode capsule layer, and the reaction speed is fast; The discharge of the tip of the imaging pen eliminates the electric field between the upper and lower plates, so that the electronic blackboard displays the color of the liquid in the microcapsules, adding a color display and making the electronic blackboard more functional.

Description

technical field [0001] The invention relates to the technical field of information display, in particular to an electronic blackboard and an imaging pen. Background technique [0002] Blackboards and chalks are the most common props in teaching. Traditional blackboards and chalks will generate a lot of dust during the teaching process, which will cause various respiratory diseases such as tuberculosis. At the same time, with the rapid development of multimedia technology, traditional blackboards and chalk can no longer meet the needs of multimedia teaching. In this case, electronic blackboards have emerged as the times require. [0003] The existing electronic blackboard generally adopts an electronic blackboard with an electrophoretic display panel, which is composed of a transparent panel, a precise positioning test layer, an electrophoretic display panel, a driving electrode layer and a backplane in sequence. When the operator writes on the transparent panel with a mouse...
