Problems solved by technology

On the one hand, the cost of the touch module and the display screen of such a handwriting screen is very high, and it is necessary to integrate software and hardware between the touch screen and the display screen system, so the manufacturing cost is relatively high.
And because the display screen and circuit system need continuous power, the battery life is low

Abstract

The embodiments of present invention disclose an electronic handwriting screen and relate to the field of electrophoretic display techniques. In the embodiment of present invention, because insulation spacing elements are provided between the electrophonic display functional film and the bottom electrode, when an appropriate voltage is applied between the top electrode and the bottom electrode, the top electrode is pressed so as to make the electrophonic display functional film contact with the bottom electrode, which shortens the distance between the top electrode and the bottom electrode and further increases the electric field force acting on the charged colorant particles; as a result, electrophoresis effect occurs in the electrophoresis liquid so that patterns are displayed or erased at the pressing location, and handwriting function is thereby realized without a touch screen, reducing the manufacturing costs for an electronic handwriting screen.

Description

technical field [0001] The invention relates to the technical field of electrophoretic display, in particular to an electronic handwriting screen. Background technique [0002] Electronic paper technology is a new type of display technology, which is currently widely used in electronic readers. Electronic technology is currently dominated by electrophoretic display technologies in the form of microcapsules and microcups, both of which realize at least two-color display through electrophoretic fluid. [0003] The structure of the existing micro-cup electronic display is as follows: Figure 7 As shown, the display screen includes a top electrode 61, a bottom electrode 62, and an electrophoretic display function film 63 arranged between the top electrode 61 and the bottom electrode 62. The electrophoretic fluid 632 in each microcup of the array 631 , the charged pigment particles 633 dispersed in the electrophoretic fluid 632 , and the sealing layer 634 used to seal the openin...
