Detailed Description
The technical solutions in the embodiments of the present invention will be described clearly and completely with reference to the accompanying drawings in the embodiments of the present invention, and it is obvious that the described embodiments are only some embodiments of the present invention, not all embodiments. Based on the embodiments in the present invention, all other embodiments obtained by a person skilled in the art without creative work belong to the protection scope of the present invention.
Referring to fig. 1, the present invention provides a technical solution:
a light energy writing device is shown in figure 1 of the specification, and comprises a flexible substrate 1, a transparent conducting layer 2, a composite layer 3 formed by alternately arranging bistable cholesteric liquid crystals 31 and cured polymers 32, a conducting layer 4 and a flexible substrate conducting layer 5 which are sequentially arranged.
The flexible substrate 1 is made of a PET (polyethylene terephthalate) material, is positioned on the uppermost layer and is jointed and connected with the transparent conducting layer 2 positioned on the next upper layer, and the transparent conducting layer 2 is made of an indium tin oxide material; the composite layer 3 is positioned in the middle layer, is upwards attached and connected with the bottom surface of the transparent conducting layer 2 and downwards attached and connected with the upper surface of the conducting layer 4, and the conducting layer 4 is also made of an indium tin oxide material; the lower surface of the conducting layer 4 is attached to and connected with the flexible substrate conducting layer 5, and the flexible substrate conducting layer 5 is also made of polyethylene terephthalate.
The flexible substrate 1, the transparent conductive layer 2, the composite layer 3, the conductive layer 4 and the flexible substrate conductive layer 5 are bonded together through the optical adhesive 7.
The laminating department between flexible substrate conducting layer 5 and the hard thing support 6 also is connected through the laminating of optical cement 7, and hard thing support 6 chooses for use the aluminum alloy honeycomb panel material to make for use, is used for providing the holding power of whole blackboard, and above-mentioned optical cement 7 all adopts OCA (organic silicon rubber optics transparent double faced adhesive tape), completion laminating bonding connection that can be fine.
The working principle is as follows: the optical energy blackboard takes the display of bistable cholesteric liquid crystal 31 as a technical basis, the bistable liquid crystal is mainly characterized in that two stable states exist without an external electric field, and the two stable states can be kept stable without the external electric field, so that a bright state and a dark state are presented, through the matched use of the flexible substrate 1, the transparent conducting layer 2, the conducting layer 4 and the flexible substrate conducting layer 5, when a writing film is subjected to certain pressure, stressed liquid crystal molecules can record pressure tracks according to the force size and the application direction, and under the drive of certain voltage waveform, the bistable liquid crystal screen can be restored to an initial state, the liquid crystal molecules can be rapidly switched between the bright state and the dark state, the purpose of clearing writing marks is achieved, and the whole writing and erasing process can be efficiently completed by the system.
Although embodiments of the present invention have been shown and described, it will be appreciated by those skilled in the art that changes, modifications, substitutions and alterations can be made in these embodiments without departing from the principles and spirit of the invention, the scope of which is defined in the appended claims and their equivalents.
