Embodiment Construction
[0024] For better understanding and implementation, the technical solutions in the embodiments of the present invention will be clearly and completely described below in conjunction with the drawings in the embodiments of the present invention.
[0025] In the description of the present invention, it should be noted that the terms "upper", "lower", "front", "rear", "left", "right", "vertical", "horizontal", "top", The orientation or positional relationship indicated by "bottom", "inner", "outer", etc. is based on the orientation or positional relationship shown in the drawings, and is only for the convenience of describing the present invention and simplifying the description, rather than indicating or implying the referred device or positional relationship. Elements must have certain orientations, be constructed and operate in certain orientations, and therefore should not be construed as limitations on the invention.
[0026] Unless otherwise defined, all technical and scien...

The invention relates to the technical field of display, and particularly discloses an electronic paper handwriting board. The electronic paper handwriting board comprises a handwriting board body and an electronic pen. The handwriting board body is provided with electronic paper, and the electronic paper comprises a conductive layer and a display layer which are electrically connected with each other and stacked; electrophoretic liquid and electrophoretic particles are arranged in the display layer; the electronic pen is provided with a power supply and a pen point electrically connected to the power supply; the power supply is used for providing voltage with the electrical property opposite to that of the electrophoretic particles for the pen point. The pen point is used for driving the electrophoretic particles when making contact with the display layer, so that the electrophoretic particles can move in the direction from the position close to the conductive layer to the position away from the conductive layer, therefore, the display side of the display layer displays characters or patterns, and the writing of the characters or patterns is completed. Compared with a liquid crystal handwriting board, characters or patterns of the electronic paper handwriting board can be continuously displayed without power supply after being written, so that the use power consumption is low, and the electric energy can be saved; moreover, the display effect is close to that of paper, eyes are not prone to fatigue, damage to the eyes is small, and therefore the effect of protecting the eyes can be achieved.
Description
technical field [0001] The invention relates to the technical field of handwriting boards, in particular to an electronic paper handwriting board. Background technique [0002] Handwriting boards are usually used for teaching, meeting discussions, personal use, etc., and are widely used because they are easy to move and carry, and have the characteristics of being rewritable and rewritable. With the development of science and technology, there are liquid crystal writing boards on the market. By setting the control module and the LCD touch screen, the writing and clearing of text and patterns can be realized. However, the liquid crystal writing board needs continuous power supply to continue displaying. Higher, and the brightness of the liquid crystal display is too high, it is easy to make our eyes tired, and it is more harmful to the eyes. Contents of the invention [0003] In order to overcome at least one defect of the above-mentioned prior art, the present invention p...
