Abstract
The utility model discloses a dual-screen electronic table board comprising a main control IC, a main display screen, a main memorizer, an outer screen control IC and an outer display screen, wherein the main display screen is controlled by the main control IC; the outer display screen is controlled by the outer screen control IC which is controlled by the main control IC; and the main control IC is connected with a key and a USB interface. The dual-screen electronic table board solves the electronization problems of a common table board, and can conveniently type in the conferee information and meeting content through the USB interface to display same by the display screen.
Description
Technical field
The utility model relates to video conference field of display devices, electronic display technology field, relates in particular to a kind of double-screen electronic table board.
Background technology
At present, in social activitieies such as commercial affairs, office, service, need use multiple office equipment, and, along with society improves further to the requirement of office efficiency, service quality, information transparency, press for office equipment and office process are carried out digital improvement.When holding a meeting, need be participant's indicate identification usually, realize that by common table board function is very limited at present, can not satisfy the needs of digital improvement.
The utility model content
The purpose of this utility model is to provide a kind of double-screen electronic table board that can show participant's information and conference content automatically, and the utility model provides the very low double-screen electronic table board of a kind of power consumption.
To achieve these goals, the technical solution adopted in the utility model is as follows:
Double-screen electronic table board of the present utility model, comprise: master control IC, main display, primary memory, outer screen control IC, outer display screen, outer screen storer, power supervisor (PMU), button, described main display links to each other with described primary memory, and be connected to described master control IC, described outer display screen links to each other with described external storage, and be connected to described outer screen control IC, described outer screen control IC is connected to described master control IC, also be connected with button and USB interface on the described master control IC, described power supervisor is connected respectively to button and master control IC, also is connected with power supply adaptor on the described power supervisor.
Described power supervisor adopts the 5V power voltage supply.
Described 5V voltage is provided by the step-down of 7.4V lithium battery.
The beneficial effects of the utility model are as follows:
Double-screen electronic table board of the present utility model shows synchronously by the programmed control double screen, also can be controlled at outer display screen and show participant's name, display conference content on main display, very convenient, and the employing low-voltage power supply, and provide by the lithium battery step-down, can reduce electric energy loss.
Description of drawings
Fig. 1 is the structured flowchart of the utility model double-screen electronic table board.
Embodiment
Referring to accompanying drawing 1, double-screen electronic table board of the present utility model comprises: master control IC, and it is the centralized control IC of all instructions, controls all peripheral circuits, and carries out signal communication with outer screen control IC, but does not carry out data communication; Two display screens, two storeies, wherein main display and primary memory are directly controlled by master control IC, outer display screen links to each other with external storage, and by outer screen control IC control, the demonstration of the outer screen of outer screen control IC control and the execution of instruction, output feedback signal is given master control IC simultaneously, master control IC is by finishing the judgement to button with line scanning and field scan, realize keypress function, power supply adaptor can provide the direct supply of 5V for double-screen electronic table board of the present utility model, and power supervisor can be realized the power supply of equipment to different DC voltage-stabilizing.
Double-screen electronic table board of the present utility model comprises USB interface, can import the Logo of enterprise, name information, conference content by USB interface, and table board ROMPaq, has overturned the traditional approach that carries out data transmission in wired mode.Based on lithium battery power supply and usb data transmission, double-screen electronic table board of the present utility model is under the prerequisite that reaches general table board function, realized portable and wireless mode work truly, at the meeting scene, need not provides power supply and network layout outward for electronics table horizontal inscribed board again.
When using, double-screen electronic table board of the present utility model can master routine and participant information stores be arrived primary memory by programmed control, and show by main display, when needs display screen demonstration outside, then will need content displayed to store external storage into, thereby be shown to outer display screen.
