Embodiment 1
[0039] In order to solve the above technical problems, such as Figure 1-Figure 3 As shown, the first aspect of the present application provides an electronic writing system, including: a communication-connected external processing device and an electronic writing device. Exemplarily, the external processing device can be a display of a computer, a tablet computer, or a mobile phone, etc., to The handwriting written by the user in the electronic writing device is displayed synchronously on the display.
[0040] The electronic writing device in the present invention will be further described in detail in conjunction with the accompanying drawings and specific embodiments:
[0041] This embodiment provides an electronic writing device, including:
[0042] A cholesteric liquid crystal display component with multiple areas to be written;
[0043] Specifically, the cholesteric liquid crystal display assembly is divided into multiple sub-cholesteric liquid crystal display assembli...
Embodiment 2
[0069] Compared with the electronic writing equipment provided in Embodiment 1, the electronic writing equipment proposed in this embodiment has the following differences: Figure 4 As shown, the cholesteric liquid crystal layer 5 is divided into a plurality of sub-cholesteric liquid crystal layers, and the plurality of sub-cholesteric liquid crystal layers are arranged in an array, and are arranged in one-to-one correspondence with a plurality of areas to be written. The design of this embodiment is adopted , can better realize the separate erasing of each area to be written, so as to improve the local erasing efficiency of the electronic writing device.
Embodiment 3
[0071] Compared with the electronic writing equipment provided in Embodiment 2, the electronic writing equipment proposed in this embodiment has the following differences: Figure 5 As shown, an elastic pressure-sensitive conductive layer 13 is arranged between the cholesteric liquid crystal layer 5 and the second electrode layer 2, and the elastic pressure-sensitive conductive layer 13 is divided into a plurality of sub-elastic pressure-sensitive conductive layers, and a plurality of cholesteric Type liquid crystal layers 5 are set in one-to-one correspondence; in this embodiment, the first electrode layer 1, the cholesteric liquid crystal layer 5, the elastic pressure-sensitive conductive layer 13, the second electrode layer 2 and the Hall element 6 are connected in series; , the elastic pressure-sensitive conductive layer 13 can be a film with pressure-sensitive properties made of a single substance, or a film with pressure-sensitive properties formed by mixing two or more s...
