First embodiment
Fig. 1 and Fig. 2 is please referred to, the present embodiment provides a kind of pixel walls 100, including skeleton 110, are successively set on institute
State the installing plate 120 on skeleton 110 and multiple latticed mechanisms 130.
The skeleton 110 plays the role of supporting overall structure and installation, as a kind of embodiment, the skeleton
110 can be zinc-plated square tube.
In order to play a protective role to pixel wall 100, zinc-plated plate surface baking vanish can be set outside the skeleton 110,
Thickness can be 2mm.
Installing plate 120 can be circuit board, play the role of turning circuit.
Wherein, the figure that the multiple fenestral fabric 130 is formed can be as shown in Figure 1 rectangle, it is, of course, also possible to
It is other regular figures, such as circle, triangle etc..As a kind of embodiment, the multiple fenestral fabric 130 is formed
Figure can also be the irregular figures such as cartoon character, love, expression.
Wherein, corresponding light source 131 and sensing unit 132, Mei Gesuo are provided in each latticed mechanism 130
It states sensing unit 132 included in latticed mechanism 130 to be electrically connected to each other with light source 131, and electric with the installing plate 120
Connection, such as can be electrically connected by conducting wire.
Light source 131 in each latticed mechanism 130 can be LED light, wherein, the color of LED light can be the same,
Different colors can also be used;Light source 131, which may be used, is lit the bright LED light of duration, can also use and be dodged when being lit
Bright LED light.Light source 131 can also be other light sources.
The sensing unit 132 is used to play control action to the light source 131.
Further, the sensing unit 132 can include conducting state and closed state.When the sensing list of certain
When member 132 is in the conduction state, the light source 131 being connect with the sensing unit 132 is lit, when the sensing unit 132 of certain
In the closure state, the light source 131 being connect with the sensing unit 132 extinguishes.
Further, the sensing unit 132 can be tongue tube.
At the two panels endpoint of tongue tube be overlapped magnetizable reed, be sealed in a glass tube, two reeds separate away from
From only about several microns, be filled in glass tube the inert gas of high-purity, when not yet operating, two panels reed and not in contact with,
Additional magnetic field makes two panels reed endpoint location nearby generate different polarity so that the reed of two panels opposed polarity will be mutually attracting
Draw and be closed.Technology can make the changeover module of very reduced size volume according to this, and switch speed is quick and has very excellent
Different reliability.
Therefore, when made of magnetic material pixel stick 210 be inserted into the latticed mechanism 130 of certain, close to the net
During tongue tube in trellis mechanism 130, the magnetic field that magnetic material is formed so that tongue tube is in the conduction state, with the tongue tube
It is connected and is lit between the light source 131 of connection and installing plate 120;When pixel stick 210 detaches latticed mechanism 130, at tongue tube
When closed state, the light source 131 that is connect with the tongue tube and the separated of installing plate 120 and extinguish.
It is more in pixel wall 100 if being inserted into multiple pixel sticks 210 respectively in different latticed mechanisms 130 simultaneously
A light source 131 will can be lit, so as to show different images.Since each latticed mechanism 130 is fitted with light source 131
And sensing unit 132, pixel stick 210 can then plug in each latticed mechanism 130, sensing unit 132 be triggered, so as to control lamp
Light effect.User can risk preset pattern, and " lighting " pattern with memory.Due to the light of each latticed mechanism 130
Can individually control, the pattern risked can realize flash, illusion-colour discoloration, even dynamic animation effect greatly enriched playing method
Content enhances interactivity.Certainly, the playing method of pixel wall 100 is not limited to the object for appreciation of above-mentioned " risking predetermined pattern with memory "
Method can also chase flashing light, arbitrarily splice figure, searching special pixel point and other innovative playing methods.
Further, it can also set and control some sensing unit 132, light so as to triggering whole face pixel wall 100
Special graph.
Certainly, it is worth noting that, tongue tube is merely illustrative, the sensing unit mentioned by the embodiment of the present invention
132 are not merely confined to tongue tube, other can be used as sensing unit 132, example as the device of control switch
Such as it is that microswitch is either infrared switch or is laser sensor.
No matter for the figure that latticed mechanism 130 is formed for rule or irregularly, the multiple latticed mechanism 130 is equal
Arrangement form multiple lines and multiple rows.
Due to latticed mechanism 130 have it is multiple, each need lighting effects and sensing control.By common practices, each
Normal wiring (4 lamp lines, 2 sensing control lines, totally 6 lines), it will cause wiring it is various (be, for example, 20 × 20=400,
There will be 2400 lines), it is whole too fat to move, lead to that line fault increases and cabling space is insufficient.
In order to solve this problem, conducting wire is accessed circuit board by lamp line by the present embodiment using socket form, and senses control
System then introduces matrix form wiring.The lamp line of light source 131 in i.e. each latticed mechanism 130 is electric with the installing plate 120 respectively
It connects, each sensing unit 132 in the latticed mechanism 130 of same a line in the matrix passes through a sensing and controls
Line is connected, and each sensing unit 132 in the latticed mechanism 130 of the same row in the matrix is controlled by a sensing
Line series connection processed.Specially:2 lines of sensing unit 132 by horizontal, longitudinal direction are connected with each other, conspire to create 400 sensing units 132
20 rows, 20 arrange, often 1 piece-root grafting line of capable/each column, therefore only need 40 piece-root grafting lines.Sensing identification method is changed to progressively scan, principle
It is similar with computor-keyboard principle.It is the level state for detecting each row successively by setting low level line by line, to determine which is latticed
Mechanism 130, which is triggered, to be lighted.And then greatly reduce the wiring quantity of pixel wall 100.
Again since this programme needs real-time and precise to detect multiple latticed mechanisms 130 while situation about being triggered, and not only
Only it is to pull away the single-point inductive mode of pixel wall after triggering some latticed mechanism 130.If with common matrix solution, it will
There is the chaotic situation of triggering.
Fig. 3 is please referred to, when A1, A2, A3, A4, B1 are triggered, B2, B3, B4 will be unable to be sensed or by system
Think to be triggered.In fact, as long as 2 buttons of colleague are triggered, for example A1, A2 are triggered, then on 1,2 liang of all row of row
High level can be set to, low level scanning line by line just loses meaning, therefore can not realize that multiple spot triggers.
In order to solve this problem, Fig. 4 is please referred to, the embodiment of the present invention is on a sensing control line is connected on and adjacent
Two sensing units 132 between be provided with diode.
Further, complicated triggering confusion can be solved the problems, such as by the one-way conduction characteristic of diode.Utilize
The reversed release property of diode, when A1, A2 are triggered at the same time, it is high level that will not arrange the conducting of other rows by 1,2 liang.
Certainly, it is also provided with leading in each latticed mechanism 130 for the pixel wall 100 that the embodiment of the present invention is provided
To plate, for extraneous pixel stick 210 to be guided to be inserted into the latticed mechanism 130.
