Abstract

The invention provides a handwritten electronic paper display, relating to the technical field of electronic paper. The handwritten electronic paper display comprises a first electrode substrate (1) and a second electrode substrate (2) which have the same pixel electrode lattice structure, an electronic paper film (3), a flexible circuit board (4), a handwritten pen (5) and a power supply, wherein the electronic paper film (3) is adhered on the upper surface of the first electrode substrate (1), and a common electrode of the electronic paper film (3) is electrically connected with a negative pole of the power supply; a film forming layer of the second electrode substrate (2) is upward fixed on the electronic paper film (3); the flexible circuit board (4) is used for electrically connecting pixels of the first electrode substrate (1) with the pixels of the second electrode substrate (2); and the handwritten pen (5) is electrically connected with a positive pole of the power supply. According to the invention, handwriting function can be realized, structure is simple, cost is low, and energy is saved.

Description

technical field [0001] The invention relates to the technical field of electronic paper, in particular to a handwritten electronic paper display and a manufacturing method thereof. Background technique [0002] An electronic paper display is a display device driven by an electric field, and the materials used for display are mainly "electronic ink" and "microcapsules". Electronic ink itself is a liquid that can be printed or applied to any carrier surface. The original electronic ink is composed of very small black and white particles suspended in a transparent liquid. Microcapsule technology is to wrap electronic ink in microcapsules, thus solving the problem of aggregation of pigment particles. [0003] These capsule particles injected with electronic ink are electrically charged, the white particles are positively charged, and the black particles are negatively charged. When a negative electric field is applied above the transparent electrode plate, the positively charg...
