CPC G06F 3/046 (2013.01) [G02F 1/13338 (2013.01); G06F 3/0412 (2013.01); G06F 3/0416 (2013.01)] | 15 Claims |
1. A pressure-sensitive writing board, comprising:
a pressure-sensitive writing panel configured to form a writing region; and
a writing monitoring unit configured to determine position information about a writing tool at the writing region, convert the position information into writing trajectory information, and store the writing trajectory information,
wherein the pressure-sensitive writing panel is further configured to present the writing trajectory information at the writing region;
wherein the pressure-sensitive writing panel comprises a pressure-sensitive display module configured to present a writing trajectory in a predetermined color in accordance with the writing trajectory information at a region where a pressure is applied;
wherein the pressure-sensitive display module is further configured to erase the writing trajectory under the effect of a predetermined pulse electric field;
wherein the pressure-sensitive writing panel further comprises a protection layer attached to a surface of the pressure-sensitive display module where a pressure is applied;
wherein the protection layer comprises a flexible soft film subjected to atomization and hardening treatment;
wherein the writing monitoring unit comprises an electromagnetic induction layer attached to a surface of the pressure-sensitive writing panel away from a writing surface of the pressure-sensitive writing panel, a maximum value of a total thickness of the pressure-sensitive writing panel is positively associated with a sum of densities of antenna arrays on the electromagnetic induction layer, and the total thickness of the pressure-sensitive writing panel is a distance between a surface of the protection layer away from the pressure-sensitive display module and a surface of the pressure-sensitive display module adjacent to the electromagnetic induction layer.
