It should be noted that the features of the embodiments of the present invention may be combined with each other without conflict.
Referring to FIG. 4, in one embodiment, the present invention discloses a hard screen comprising:
the LED lamp comprises a rigid material, a circuit arranged on the rigid material and a plurality of LED luminous bodies arranged on the rigid material;
wherein the content of the first and second substances,
each LED luminous body comprises coded information of the LED luminous body;
the line is a three-wire system and comprises the following three types of lines:
the first-type connecting wire is used for electrically connecting the power supply anode/VCC end of each LED luminous body;
the second type of connecting wire is used for electrically connecting the power supply cathode/GND end of each LED luminous body;
the third type of connecting wire is used for electrically connecting the DIN end of the data signal input pin of each LED luminous body so as to provide a data signal;
and each LED luminous body acquires a corresponding data signal aiming at the LED luminous body from the data signal according to the coding information of the LED luminous body.
For the above embodiment, only the three wire system is used, and the data signal output pin DOUT is also eliminated compared to the prior art hard screen. For fig. 4, the wiring and the plurality of LED luminaries are more illustrated, without the stiff material.
Comparing fig. 4 with fig. 2, fig. 2 illustrates a structure of a hard screen in the prior art:
although the controller of fig. 2 also utilizes only one DATA signal, i.e., DATA1, this is seemingly the same as the DIN-only one DATA signal shown in fig. 4 of the present invention, but:
in the order from right to left in fig. 2, it can be found that: in fig. 2, in order to implement the breakpoint resume function, the DATA1 is directly connected to the DIN1 pin of the first LED luminary and also connected to the DIN2 pin of the second LED luminary, so as to ensure that the second LED luminary can still obtain the DATA signal from the DATA1 through the DIN2 pin even if the first LED luminary is not working normally and its DOUT cannot send a valid signal. If the first LED luminary is operating properly, DOUT will forward a DATA1 signal processed by the first LED luminary and pass to DIN1 pin of the second LED luminary. And a third LED illuminator, and the like.
It is apparent that for the prior art illustrated in fig. 2: the primary pin for transmitting data signals is DIN1, and DIN2 provides redundancy only when DIN1 fails to receive signals or operates abnormally. Also, the signal of DIN1 is by default from DOUT of the preceding stage, and the signal of DIN2 is by default from DIN1 of the preceding stage. For the subsequent stage, the signal itself input in DIN1 of the subsequent stage is processed by the previous stage, so that the subsequent stage can directly acquire the data signal corresponding to the subsequent stage; alternatively, the signal input in DIN2 by the subsequent stage is processed by the subsequent stage according to a fixed processing algorithm, and the subsequent stage can still obtain the data signal corresponding to the subsequent stage. In other words, even if the first LED luminary near the controller is not operating properly on the right side of fig. 2, the second LED luminary in the subsequent stage will also operate properly. When only the first LED luminous body and the second LED luminous body are failed, the condition of large-area failure can be generated in the rest rear stages. That is, for the hard screen of the breakpoint transmission scheme shown in fig. 2, if 2 consecutive lights fail, the corresponding subsequent stage will fail as a whole.
Compared with the prior art shown in fig. 2, the invention can completely avoid DIN2 pins/terminals and corresponding wiring, because each LED luminous body has self corresponding coding information, the invention only needs to obtain corresponding data signals aiming at the LED luminous body from the data signals according to the coding information of the LED luminous body, thereby ensuring the normal work of each LED luminous body. The prior art shown in fig. 2 does not rely at all on the coding of the LED luminary, but: the data signal is processed by the previous stage and then transmitted to the next stage through the DOUT, or the signal of the next stage according to DIN2 is processed according to a fixed processing algorithm, and then the data signal required by the stage is acquired and transmitted back through the DOUT. The coded information in the invention refers to address coded information or ID coded information of each LED luminous body so as to distinguish each LED luminous body, the information can be rigidly stored in the LED luminous bodies in an OTP mode or other burning technology, and the state of the related storage element is changed so as to be solidified and rigidly stored.
The invention can obviously reduce the wiring complexity and the wiring cost thereof, can also obviously reduce the failure rate and improve the yield rate because the invention can avoid removing redundant pins of DIN2 and the wiring connected with the former stage DIN1, and can avoid removing the wiring connected with the former stage DOUT by the latter stage DIN1, and only adopts a three-wire system to connect all LED luminous bodies. Typically, the third-type connecting line is used as a data signal line and is directly connected with DIN of each LED luminary, each LED luminary has its own coding information and correctly acquires a data signal corresponding to the LED luminary from the data signal line, and each LED luminary is connected with VCC and GND corresponding to the LED luminary, so that when any one LED luminary fails, even two or more LED luminaries fail, the hard screen of the present invention can still ensure the operation of the other luminaries.
In addition, comparing the present invention with the prior art shown in fig. 3:
the controller of fig. 3 adds a DATA signal, i.e., DATA2, compared to fig. 2, unlike the DIN DATA signal alone shown in fig. 4 of the present invention. It is apparent that fig. 3 is more complex in wiring than the prior art of fig. 2, and is more susceptible to increased faults than the prior art shown in fig. 2.
In conclusion, the invention can effectively reduce the total cost of the hard screen and improve the yield.
In a further embodiment of the method according to the invention,
the hard material is a material with certain light transmittance.
Some light transmission, for example near complete transparency, or translucency, depends on what visual effect the hard-screen is intended to achieve. In addition, it should be noted that, because the number of the wiring lines of the present invention is reduced, the corresponding solder points are also reduced, and the transparency of the hard screen of the present invention is further improved for the same transmittance of the hard material. Compared with the prior art, the invention can improve the wire width of the wiring in the hard screen to improve the current bearing capacity on the premise of meeting the transparency because the number of the wiring is reduced.
In another embodiment of the present invention, the substrate is,
the hard screen is a glass screen.
In another embodiment of the present invention, the substrate is,
the line is arranged on one side of the hard material.
In another embodiment of the present invention, the substrate is,
the hard screen has any one of the following characteristics:
(1) every 2 hard screens can be spliced into 1 screen;
(2) the LED luminous bodies are connected in parallel.
For the 2 embodiments described above, it can be found that:
according to the technical scheme, the through hole is not needed, so that the three-wire line can be arranged on one surface of the hard material. The adhesive is arranged on one surface, and the other surface can be used for application and installation.
In addition, every 2 hard screens can splice into 1 screen, only need two hard screen between the first type connecting wire, second type connecting wire, third type connecting wire electric connection each other can.
In addition, for each hard screen, the plurality of LED light emitters are preferably arranged in parallel, which is more beneficial for splicing. The parallel connection is preferred, which means that other connection modes are not completely excluded, and the basic voltage and current resistance requirements are met whether the connection modes are in series connection or in parallel connection or in series-parallel connection. Although this embodiment emphasizes the splicing, it is not excluded to cut the hard screen, as long as the function of the various connecting lines is still made generally normal, and the function of the corresponding LED luminary is generally normal.
In another embodiment of the present invention, the substrate is,
the first connecting lines, the second connecting lines and the third connecting lines are parallel to each other.
In another embodiment of the present invention, the substrate is,
the first type connecting line, the second type connecting line and the third type connecting line are provided with one line at least.
In another embodiment of the present invention, the substrate is,
the LED luminous bodies are arranged in a plurality of parallel rows/columns.
To above-mentioned 2 embodiments, can understand, parallel between each connecting wire, a plurality of LED luminous bodies set up to a plurality of parallel row/row, all are favorable to visual effect and concatenation.
In another embodiment of the present invention, the substrate is,
the first-type connecting lines, the second-type connecting lines and the third-type connecting lines are all arranged into one-layer lines or two-layer lines.

In another embodiment, the LED luminary comprises a patch LED.
In another embodiment, the LED luminary comprises: at least 1 LED lamp pearl chip and any IC or other components and parts of connecting LED lamp pearl chip.
It should be noted that, in terms of LED lighting, whether AC or DC driven, the minimum requirement of the LED itself is two wire power. Due to the development of LED chip technology, even without a driving IC, an LED light emitting body can be formed using a certain number of LED chips having a small occupied area and directly driven by AC or DC.
In addition, it should be noted that, in the field of driving of LEDs, a technique of transmitting a data signal while supplying power by using a power supply line such as a line zero line/a line positive negative line has appeared. This corresponds to a carrier technology. This means that even without a connection line of the third type, it is equally capable of transmitting data signals only via the connection lines of the first type and the connection lines of the second type. Whether the data signal is a specific code signal for different LED luminaries or different LED chips in a single LED luminary, whether the data signal is an address code signal for a specific LED luminary/LED chip or a color signal for the color of the lighting or display, the transmission of the corresponding data signal can be achieved by using such a carrier technology.

the LED luminous bodies are arranged at equal intervals.
In another embodiment of the present invention, the substrate is,
and the LED luminous bodies of each row/column on the hard screen are arranged in the row/column at equal intervals.

In another embodiment of the present invention, the substrate is,
at the positive both ends of support plate, still be provided with:
the data signal input pin DIN terminal is used for electrically connecting the LED luminous body.
In this way, the carrier board can be cascaded back and forth with a carrier board of the same structure, even if data signal input is involved.
In another embodiment of the present invention, the substrate is,
