When more than one handwriting liquid crystal screens are installed on the desk with the liquid crystal handwriting board function, independent keys are arranged beside each screen, the keys of each screen are connected to a control board, and each screen is managed by one circuit control board; when a key beside the screen is pressed, the circuit control board judges which screen sends the request, and the power is independently switched on for the screen.
The handwriting liquid crystal screen, the keys and the circuit control panel arranged on the desk with the liquid crystal handwriting board function can be detached and replaced.
The desk is also provided with a clamping groove for placing a handwriting pen.
The table body with the liquid crystal handwriting board function is a table with a table top and table legs.
The table type with the liquid crystal handwriting board function comprises a dining table, a learning table, an outdoor table, an office table, a folding table and a conference table.
Description of the drawings:
FIG. 1 is a schematic structural diagram of an embodiment of the present invention;
in the figure, 10-a desk 11 with a liquid crystal handwriting board function-a flexible bistable liquid crystal screen 12-a handwriting pen groove 13-a key 14-an external power interface 15-a power switch 16-a circuit control board 17-a battery 18-a power pin.
The specific implementation mode is as follows:
the invention will be described in further detail below with reference to the drawings and specific embodiments, but the invention is not limited to the embodiments shown.
Referring to fig. 1, a structure of a table with a liquid crystal writing pad function according to an embodiment of the present invention is shown, and for convenience of description, only portions related to the embodiment of the present invention are shown.
A liquid crystal handwriting screen 11 using a flexible bistable cholesteric liquid crystal screen, a key 13 and a groove 12 for placing a handwriting pen are arranged on the desktop of the desk 10 with the liquid crystal handwriting board function, and an external power interface 14 and a power switch 15 are arranged on the side surface of the desk 10; the liquid crystal handwriting screen 11 and the keys 13 are connected with the circuit control board 16; the external power interface 14 and the power switch 15 are connected to the circuit control board 16 together with the power pin 18 on the circuit control board 16 to supply power to the circuit control board 16; a battery can be arranged on a battery position 17 on the circuit control board and is connected with a power pin 18 to supply power to the circuit control board; when the power switch 15 is turned off, the circuit control board is in a power-off state, and does not provide the converted voltage to the liquid crystal handwriting screen 11, and the pattern formed by pressing the liquid crystal handwriting screen 11 cannot be removed; when the power switch 15 is turned on, the battery arranged on the battery position 17 or the external power interface 14 supplies power to the circuit control board through the power pin 18, and when the key 13 is pressed, the circuit control board 16 releases the converted voltage to the liquid crystal handwriting screen 11, and the patterns on the liquid crystal handwriting screen 11 are erased; the writing pen can be placed in the groove 12 to prevent loss when not used; in this embodiment, two liquid crystal handwriting screens 11 are installed on the desk 10, and both are connected to the same circuit control board 16, and when the key 13 is pressed, the circuit control board 16 determines to which liquid crystal handwriting screen the switching voltage is released.
