Description

A kind of graphics device

The utility model relates to a kind of graphics device.

At present, the common display device of seeing that is used for display graphics of people, the mainly LED display of forming by LED (light emitting diode) dot matrix and driving circuit, control circuit, memory circuit etc.By control circuit, the graph data to be shown that is stored in advance in the memory circuit, after driving, lights by driving circuit LED corresponding in the LED dot matrix circuit, show the figure that pre-sets.But because each point in the shown figure, it is corresponding one by one with it all to have required a LED to come, and so just causes present LED display volume excessive, and cost is too high.For example, show that the dot matrix that each Chinese character (GB5007) needs 15 * 16 LED to form at least shows, when showing a plurality of Chinese characters or more complicated figure, just need more LED to support.Therefore, the present display screen of forming by the LED dot matrix that is used for display graphics, inevitable volume is big, complicated, cost is high, and show that the picture and text style is stiff, effect is single, dumb, be difficult for satisfying the request for utilization of family, small-sized meal, trip restaurant, public place of entertainment etc.

In view of the above fact, the purpose of this utility model is, a kind of graphics device of novelty is provided, and this installation cost is low, it is many to be easy to the graphic style realizing, show.

For achieving the above object, solution of the present utility model is: a kind of graphics device, this device includes runing rest, base member case, motor, the rotation axis of motor, control circuit, memory circuit, driving circuit and form by the luminous bubble point battle array that luminous bubble constitutes, wherein, support is fixed on the rotation axis of motor, be furnished with luminous bubble along compartment of terrain on the outside surface of support, the memory circuit that is connected with control circuit is used to store the show state data and the watchdog routine of luminous bubble, when the motor that is arranged in base member case drives the support rotation by its rotation axis, control circuit will be placed on the data to be shown in the storage circuit in advance, control the light on and off of corresponding luminous bubble in the luminous bubble point battle array that constitutes by luminous bubble by driving circuit, finish the demonstration of figure.

By such scheme as can be seen, the compartment of terrain is furnished with the support of luminous bubble as display body on the outside surface because the utility model adopts, when motor drives the support rotation by its rotation axis, the control circuit utilization is stored in the light on and off of the corresponding luminous bubble on the show state Data Control support of the luminous bubble in the memory circuit, and then finish the demonstration of figure, display mode novelty not only, and the quantity of luminous bubble is less than the quantity of the luminous bubble of present LED dot matrix far away on the support, therefore graphics device cost of the present utility model low, be easy to realize.Simultaneously, when motor drives support rotation by its rotation axis, the graphic style of demonstration also depends on the show state data of the luminous bubble in the memory circuit, therefore, by the show state data of different luminous bubbles are set, can make display graphics varied.

Below in conjunction with accompanying drawing the utility model is done further detailed narration.

Fig. 1 is a physical construction synoptic diagram of the present utility model;

Fig. 2 is a control circuit schematic diagram of the present utility model;

Fig. 3 is the circuit theory diagrams of the utility model embodiment;

Fig. 4 is the physical construction synoptic diagram of the utility model embodiment.

Realize that principle of the present utility model is such: according to physics principle, the retentivity time of eye of human eye is about 0.1 second, that is to say, if the cycle of a bright spot of motion was less than 0.1 second, what human eye was seen will be a bright line, the bright spot of moving with certain frequency (this frequency is much smaller than 10Hz) flicker, what human eye was seen will be row's bright spot, if a plurality of bright spots of this flicker are formed a line mass motion (translation), human eye will be seen a rectangular bright spot dot matrix, if this moment by each luminous point in the external circuit control dot matrix in difference light on and off constantly, the picture that can form a width of cloth figure or literal, same reason, if the bright spot of these flickers is evenly arranged on the annulus, allow this annulus be that axle rotates with the diameter then, each luminous point in rotating by external circuit control again is in difference light on and off constantly, and we will see the figure or the literal that show with sphere.

Graphics device of the present utility model is made up of the luminous bubble point battle array 9 that rotation axis 4, control circuit 6, memory circuit 7, driving circuit 8 and the luminous bubble 5 of runing rest 1, base member case 2, motor 3, motor constitutes, with reference to figure 1,2, wherein:

Support 1 is fixed on the rotation axis 4 of motor 3, be furnished with luminous bubble 5 along compartment of terrain on the outside surface of support 1, the memory circuit 7 that is connected with control circuit 6 is used to store the show state data and the watchdog routine of luminous bubble 5, the complexity decision of the quantity of above-mentioned luminous bubble 5, distribution and the data based figure of show state; When the motor 3 that is arranged in base member case 2 after energising, when driving support 1 rotation by rotation axis 4, the driving circuit 8 that is connected with control circuit 6, watchdog routine utilization in being stored in memory circuit 7 is stored under the control of show state data of the luminous bubble 5 in this memory circuit 7, the demonstration of figure is finished in the light on and off of corresponding luminous bubble 5 in the luminous bubble point battle array of being made up of luminous bubble 5 by driving circuit 8 control 9.

The profile of above-mentioned support 1 can be made into different shape as required, for example annular, doleiform etc., and above-mentioned luminous bubble 5 can be selected light emitting diode, bulb etc. for use as required.

Below described be exemplary embodiments of the present utility model.The typical control circuit principle of present embodiment as shown in Figure 3.V1-V16 is a light emitting diode among the figure, R1-R16 is a current-limiting resistance, MCU is a single-chip microcomputer, XTAL and capacitor C 1, C2 provide work clock for single-chip microprocessor MCU, C3 and R17 constitute the reset circuit of single-chip microprocessor MCU, single-chip microprocessor MCU is controlled and is driven lighting of corresponding light emitting diode and extinguishes by the I/O interface, watchdog routine is stored in the storer of single-chip microprocessor MCU inside with relevant video data.

Fig. 4 is the utility model embodiment physical construction synoptic diagram.Wherein the axle 10 that links to each other with the rotation axis of motor in the base 11 is the rotation axis of ring-like support 12, motor in the base 11 provides power for the rotation of ring-like support 12, make ring-like support 12 around axle 10 rotations, be stored in the watchdog routine utilization that is stored in single-chip microprocessor MCU inside under the control of show state data of light emitting diode V1-V16 of this single-chip microprocessor MCU inside, then can show spherical graphical information.

In a word; above-mentioned explanation be a kind of graphics device; it by the driven by motor support rotation and come display graphics by the light on and off that control circuit is controlled corresponding luminous bubble in the luminous bubble point battle array; therefore; any variation and remodeling around technique scheme all belong to protection domain of the present utility model.
