The objective of the invention is to be achieved through the following technical solutions:
A kind of LED display device comprises a circuit board, which is provided with the CPU (central processing unit) that a led array, motion detection mechanism and link to each other with this motion detection mechanism with this led array respectively.
Wherein, this led array comprises a plurality of LED, and this LED forms a line on this circuit board.
Wherein, this motion detection mechanism comprises first sheet metal and second sheet metal that is oppositely arranged, and also comprises a Metal Ball that is arranged between this first, second sheet metal, and this Metal Ball is fixed on the base by a spring.
Wherein, this CPU (central processing unit) comprises: time detection device is used to detect the signal that this motion detection mechanism produces, and generates a run duration; The time distributor, its described run duration of big young pathbreaker according to image to display is divided into a plurality of time quantums.
This device also comprises image display device, the respective column of its display image.
This time distributor is divided into 64 time quantums with described run duration, and this motion array comprises at least 32 LED.
Positive progressive effect of the present invention is: be adapted at the more weak occasion display image of light, and easy to use, hand swings and gets final product, and is not subjected to space constraint, and the image of demonstration can change at any time, can be used as signal lamp night and uses.

Embodiment
Provide preferred embodiment of the present invention below in conjunction with accompanying drawing, to describe technical scheme of the present invention in detail.
As shown in Figure 1, a kind of LED display device comprises a circuit board 1, which is provided with the CPU (central processing unit) 4 that a led array 2, motion detection mechanism 3 and link to each other with this motion detection mechanism 3 with this led array 1 respectively.
This led array 2 comprises a plurality of light emitting diodes 21, and this light emitting diode 21 forms a line on this circuit board 1, as shown in Figure 1.Comprise at least 32 light emitting diodes 21.
As shown in Figure 2, this motion detection mechanism 3 comprises first sheet metal 31 and second sheet metal 32 that is oppositely arranged, and also comprises a Metal Ball 33 that is arranged between this first, second sheet metal, and this Metal Ball 33 is fixed on the base 35 by a spring 34.
As shown in Figure 3, wherein, this CPU (central processing unit) comprises 4: time detection device 41 is used to detect the signal that this motion detection mechanism produces, and generates a run duration; Time distributor 42, its described run duration of big young pathbreaker according to image to display is divided into a plurality of time quantums; Image display device 44, the respective column of its display image.
This device also comprises a power supply unit 5 that links to each other with this CPU (central processing unit) 4.
In use, this device can be fixed on the matrix.The user brandishes matrix, thereby drives the to-and-fro movement of this device left and right sides.
Left and right sides to-and-fro movement arrives the edge, and when promptly reaching left and right border, because this brief acceleration can become big suddenly, the Metal Ball 33 in this motion detection mechanism 3 can be collided with this first sheet metal 31 or second sheet metal 32.When this Metal Ball 33 collides with this first, second sheet metal 31,32, can produce a look-at-me.
Described time detection device 41 is determined run duration according to the time between two look-at-mes.It starts an existing timer after obtaining first look-at-me, stop this timer when receiving second look-at-me, and writing time, be run duration (T), and then start this timer, write down next run duration, so periodic duty, as shown in Figure 5.Can adopt the prior art means to obtain described terminal signaling from this motion detection mechanism.
In the present embodiment, the size of image to display is 32 (height) * 64 (wide) pixels, and time distributor 42 is divided into 64 time quantums according to the wide of this image with described run duration T, that is to say 64 timeslices.
Reciprocally swinging about when as shown in Figure 6, this device uses.Below to show that picture shown in Figure 7 is an example, illustrates the course of work of this device.
As shown in Figure 7, the size that Shows Picture is high 32 pixels, wide 64 pixels, promptly this picture is 32 row, 64 row, then run duration T is divided into 64 time quantums, the respective column that in each time quantum, shows correspondence image, as first row of display image in first time quantum, by that analogy.
Come the row of display image by the light emitting diode of on this array of display, lighting the relevant position, during first row that Show Picture as needs, only need light the 6th and the 21st light emitting diode and get final product, as shown in Figure 7.The row image that each time quantum Shows Picture in finishing a moving process, just demonstrates whole row of image like this, because visual persistence effect, what people saw is a complete image.
This device also is provided with the memory storage that is used to store image to display, and it can be prior art.In addition, in this device, light the equipment of the light emitting diode of diverse location according to the different lines of picture, i.e. this image display device 44, it is a prior art, does not repeat them here.
