Description

Izgudrojuma aprakstsDescription of the Invention

Izgudrojums attiecas uz gaismu izstarojošiem un gaismas diožu informācijas atveides moduļiem.The present invention relates to light emitting and LED information display modules.

Zināmā tehnikas līmeņa analīzeAnalysis of prior art

Ir izstrādāts liels skaits konstruktīvu informācijas atveides risinājumu, kas balstās uz elektriskiem gaismas avotiem. Šie izstrādājumi ir dažādi demonstrācijas paneļi, displeji, informācijas izkārtnes, panno, tablo un dažādu izmēru un izšķirtspējas gaismas diožu ekrāni.A large number of constructive information display solutions based on electrical light sources have been developed. These products include a variety of display panels, displays, information signs, panes, boards and LED screens of various sizes and resolutions.

Līdz šim ierobežojumi radīt principiāli jaunas informācijas atveides sistēmas, kas balstās uz jebkuru zināmo veidu gaismas ierīcēm, elektriskiem gaismas avotiem, tai skaitā uz gaismas diodēm, bija saistīti, pirmkārt, ar pašiem informācijas signālu vadības sistēmu uzbūves principiem un elektriskās strāvas padevi gaismas avotiem, tai skaitā gaismas diožu kājiņām.Until now, the restrictions on the creation of fundamentally new information systems based on any known type of light source, electrical light sources, including light emitting diodes, were primarily related to the design principles of the information signal control systems themselves and the power supply to the light sources. including LED stands.

Tehniski nav sarežģīti izveidot statisku vai samērā vienkāršu dinamisku attēlu, kurā kādam gaismas avotam vai avotu grupai vienlaikus ar kādu citu avotu vai grupu ir jāiedegas ar vienādu gaismu vai intensitāti, turklāt nomainot kādu citu grupu. Tomēr, ja uzdevums ir atveidot pilnvērtīgu, pilnkrāsainu videoattēlu, proti, katram pikselim likt sākt spīdēt pa visu atveides virsmu neatkarīgi no citiem ar atsevišķu gaismu un intensitāti vēlamajā laika vienībā, bez mikrokontrollera (draivera), kas novietots tiešā gaismas avota tuvumā, iztikt nav iespējams.It is technically not difficult to create a static or relatively simple dynamic image in which a light source or group of light sources must light up with the same light or intensity at the same time as another source group. However, if the task is to render a full-color, full-color video image, that is, to cause each pixel to begin to shine throughout the rendering surface independently of the others with individual light and intensity at the desired time unit, without a microcontroller (driver) .

Gadījumos, kad par gaismas avotiem attēlam kalpo kādas lielākas vai mazākas gaismas ierices, draiveri ievietot pašā iericē nesagādā grūtības. Tāpat nav problēmu ar mikrokontrolleru (draiveru) izvietošanu, veidojot standartveida vienlaidus videoekrānus un tamlīdzīgus veidojumus, kam nav nepieciešamas caurspīdīgas gaismcaurlaidīgas konstrukcijas. Tomēr, ja ir nepieciešams izveidot caurspīdīgus lielizmēra ekrānus, izstrādātājiem nākas izmantot miniatūras gaismas diodes, kurām pie zema enerģijas patēriņa ir ne tikai augsta gaismas intensitāte, bet, salīdzinājumā ar citiem gaismas avotiem, ari virkne citu priekšrocību.In cases where larger or smaller light devices serve as the light sources for the image, it is easy to insert the driver into the device itself. Likewise, there are no problems with the placement of microcontrollers (drivers) for the production of standard continuous video screens and the like, which do not require transparent light-transmitting structures. However, when it comes to creating transparent large screens, developers have to use miniature LEDs, which not only have a high light intensity at low power consumption, but also have a number of other advantages over other light sources.

Daudzi izstrādātāji vienlaikus strādā pie tā, kā izvietot vadības draiverus gadījumā, ja gaismas diožu gabarīti ir pārāk mazi, un kā izveidot tik mazu izmēru draiverus, ja ir nepieciešams caur tiem laist pārāk lielu elektrisko strāvu. Šobrīd pastāv vairāki veidi caurspīdīgu gaismas diožu ekrānu, kas nosacīti izpilda šo uzdevumu (US2005233125, EP2025509, EA004517). To skaitā ietilpst ari dažādas tīklveida konstrukcijas, gaismas diožu lineāli, caurulītes, klasteri u.tml., kas izvietoti ar noteiktu soli cits no cita un kas sastāv no tekstolīta, alumīnija u.c. veidu iespiestu plašu ar elektrību vadošiem celiņiem, uz kuriem izvietoti gaismu izstarojoši elementi (gaismas diodes) un citi elektroniski komponenti, tai skaitā mikrokontrolleri (draiveri). Modulis, kas izgatavots saskaņā ar šādu tehnisko risinājumu, nav maksimāli caurspīdīgs, jo pašām platēm un uz tām izvietotajiem elektroniskajiem komponentiem ir gabarīti, kuri būtiski pārsniedz pašu gaismas diožu gabarītus, kas ir par šķērsli izstrādājumu maksimālai gaismas caurlaidībai, kuros apvienoti iepriekš minētie elementi.At the same time, many developers are working on how to deploy control drivers in the case of light-emitting diode LEDs and how to create drivers of such a small size that require too much electrical power. Currently, there are several types of transparent LED screens that conditionally perform this task (US2005233125, EP2025509, EA004517). These include various grid structures, LED rulers, tubes, clusters, etc., arranged at a fixed step from one another and consisting of textolite, aluminum, etc. a type of printed circuit board with electrically conductive paths on which light-emitting elements (light-emitting diodes) and other electronic components, including microcontrollers (drivers), are located. A module made according to such a technical solution is not as transparent as the boards themselves and the electronic components placed on them have dimensions that significantly exceed the LED dimensions themselves, which is an obstacle to the maximum light transmission of the products combining the above elements.

Daži konstruktori ir nonākuši pie secinājuma, ka, draiverus ievietojot tieši zem pašas gaismas diodes vai klastera, kas sastāv no gaismas diožu grupas, kopumā var panākt izstrādājuma lielāku caurspīdīgumu (WO 2008/074800). Šī izgatavošanas tehnoloģija, kas dod iespēju iegūt lielāku konstrukcijas caurspīdīgumu salīdzinājumā ar iepriekš aprakstītajiem variantiem, ir pārāk dārga, jo katram attēlojošajam pikselim attēlā ir nepieciešams mikrokontrolleris (draiveris). Turklāt visiem aprakstītajiem variantiem ir augstas uzturēšanas izmaksas.Some designers have come to the conclusion that placing drivers directly below the LED itself or a cluster of LEDs can generally result in greater transparency of the product (WO 2008/074800). This fabrication technology, which allows for greater design transparency than the variants described above, is too expensive because each pixel in the image requires a microcontroller (driver). In addition, all of the options described have high maintenance costs.

Izgudrojuma mērķis un būtībaPurpose and substance of the invention

Šā izgudrojuma mērķis ir izveidot maksimāli caurspīdīgu, gaismu izstarojošu moduli, kas var kalpot par videoekrānu, ar salīdzinoši nelielām ražošanas izmaksām un lielākām ērtībām to ekspluatācijā salīdzinājumā ar esošajiem analogiem.The object of the present invention is to provide a maximally transparent, light emitting module that can serve as a video screen, with relatively low production costs and greater convenience in operation compared to existing analogs.

Ar gaismu izstarojošā moduļa vai videoekrāna maksimālu caurspīdīgumu piedāvātajā izgudrojumā tiek saprasta gaismu izstarojošā moduļa īpašība pēc iespējas mazāk ierobežot moduļa gaismas caurlaides spēju tādā veidā, lai moduļa uzstādīšana, piemēram, uz ēkas fasādes, minimāli ierobežotu pārskatāmību un gaismas nokļūšanu telpās caur fasādes stiklojumam.By the maximum transparency of the light emitting module or video screen, the present invention is understood to mean the ability of the light emitting module to limit the light transmission of the module as much as possible so that installation of the module, e.g., on a building facade, minimizes transparency and penetration.

Piedāvātais gaismu izstarojošais modulis satur lielu skaitu elektriski savienotu gaismu izstarojošu elementu, kas ir atveides pikseļi. Modulis satur vismaz vienu galveno kontrolieri, kas nodrošina iespēju no videosignāla avota uz gaismu izstarojošo moduli novadīt dinamisku vai statisku attēlu, un vismaz vienu informācijas signāla un elektropadeves sadales plati, kura ir savienota ar galveno kontrolieri un gaismu izstarojošajiem elementiem ar elektropadeves un informācijas signāla padeves iespēju. Informācijas signāla un elektropadeves sadales plates ir paredzētas un pielāgotas informācijas signāla secīgai padevei ar līmeņa pastiprināšanu un impulsa kāpuma korekciju; tās ir aprīkotas ar draiveriem un programmējamiem reģistriem informācijas īslaicīgai uzglabāšanai un ir izgatavotas ar iespēju augstfrekvences informācijas signālu sadalīt starp vairākiem gaismu izstarojošiem elementiem un mainīt signāla pārraides ātrumu, samazinot nosūtāmās informācijas frekvenci atkaribā no vadītāja garuma, kas savieno gaismu izstarojošos elementus, un laika diapazonā veicot infonnācijas pakešu vispārējo sinhronizāciju (videokadru taktēšanu), tādā veidā nodrošinot tikai nepieciešamā gaismu izstarojošā elementa secīgu gaismas izstarojumu, kas ir nepieciešamajā intensitātē un nepieciešamajā laika vienībā un pēc izvēles ir ari nepieciešamajā krāsā.The proposed light emitting module contains a large number of electrically connected light emitting elements which are rendering pixels. The module comprises at least one master controller providing a dynamic or static image output from the video source to the light emitting module, and at least one information signal and power distribution board connected to the master controller and light emitting elements with power and information feed capability . The information signal and power distribution boards are designed and adapted for sequentially supplying the information signal with level amplification and pulse gain correction; they are equipped with drivers and programmable registers for temporary storage of information and are made with the ability to divide the high frequency information signal between several light emitting elements and change the transmission speed of the signal by decreasing the frequency of the transmitted information depending on the driver length connecting the light emitting elements general synchronization of the information packets (clocking of the video frames), thus providing only the successive light emitting of the required light emitting element, which is at the required intensity and in the required time unit and optionally also in the required color.

Impulsu kāpuma korekcija tiek veikta ar histerēzi. Pie barošanas sprieguma, piemēram, 5 V, ieejas signāla zems līmenis tiek uztverts 0 līdz 0,8 V diapazonā, bet augsts līmenis - 2 līdz 5 V diapazonā. Pie izejas zems signāla līmenis ir 0 V, bet augsts signāla līmenis ir 5 V.Pulse gain correction is performed by hysteresis. At a supply voltage such as 5 V, a low level of the input signal is received in the range of 0 to 0.8 V and a high level in the range of 2 to 5 V. At the output, a low signal level is 0 V and a high signal level is 5 V.

Saskaņā ar vēlamo izgudrojuma iemiesojuma variantu modulis papildus satur vismaz vienu komutācijas bloku, kas ir savienots ar galveno kontrolieri un ar informācijas signāla un elektropadeves sadales platēm ar elektropadeves un informācijas signāla padeves iespēju no galvenā kontroliera uz informācijas signāla un elektropadeves sadales platēm vai šādu plašu grupām. Informācijas signāla un elektropadeves sadales plates ir aprīkotas ar diferenciālu uztvērēju (ar informācijas signāla atkapsulēšanas moduli), bet komutācijas bloks vai bloki ir aprīkoti ar vismaz vienu diferenciālu raidītāju-pastiprinātāju.According to a preferred embodiment of the invention, the module further comprises at least one switching unit which is connected to the master controller and to the information signal and power distribution boards with power and power supply from the master controller to the information signal and power distribution boards or groups of such boards. The information signal and power distribution boards are equipped with a differential receiver (with information signal decoupling module) and the switching unit or units are equipped with at least one differential transmitter-amplifier.

Izgudrojuma būtība sīkāk ir parādīta Fig.l, kurā ir attēlota piedāvātā gaismu izstarojošo moduļu sistēmas principiālā shēma, kura satur lielu skaitu gaismu izstarojošo moduļu un ir izveidota ar iespēju uz gaismu izstarojošajiem moduļiem novadīt pilnkrāsainu dinamisku vai statisku attēlu no dažādiem videosignāla avotiem.The invention is illustrated in more detail in Fig. 1, which shows a schematic diagram of a proposed light emitting module system which contains a plurality of light emitting modules and is designed to provide a full color dynamic or static image from a variety of video signal sources to the light emitting modules.

Piedāvātais modulis nodrošina iespēju visus aktīvos elektroniskos komponentus, tai skaitā mikrokontrollerus (draiverus), izvietot ārpus attēlojošās virsmas, tos izvietot uz informācijas signāla un elektropadeves sadales platēm, lai radītu maksimāli caurspīdīgu gaismas diožu moduli, kura attēlojošās virsmas robežās ir izvietoti tikai gaismu izstarojošie elementi (atveides pikseļi) un vissmalkākie elektriskie vadītāji. Elektrisko vadītāju biezums var būt 0,2 mm vai mazāks. Katrs atveides pikselis var sastāvēt no vienas vienkrāsainas gaismas diodes, vienas daudzkrāsainas gaismas diodes, kas parasti, bet ne vienmēr, satur sarkanu, zaļu un zilu krāsu (RGB 3 vienā), no gaismas diožu grupas vai citiem zināmiem gaismas avotiem. Gaismu izstarojošie elementi ir izvietoti ar noteiktu soli cits no cita un lineāri vienā virzienā (vai jebkādā citā veidā koordinātu plaknē) ar tieviem elektriskiem vadītājiem ir saistīti ar sadales platēm.The proposed module enables all active electronic components, including microcontrollers (drivers), to be located outside the display surface, placed on the information signal and power distribution boards to produce a maximum transparent LED module with only light emitting elements within the display surface ( rendering pixels) and the finest electric conductors. The electrical conductors may have a thickness of 0.2 mm or less. Each rendering pixel can consist of one solid color LED, one multicolour LED that usually, but not always, contains red, green and blue (RGB 3 in one), a group of LEDs, or other known light sources. The light-emitting elements are arranged at a fixed step from one another and linearly in one direction (or in any other way in the coordinate plane) with thin electrical conductors connected to the distribution boards.

Informācijas signāla un elektropadeves sadales plates, pie kurām ir pieslēgti vadītāji uz gaismu izstarojošiem elementiem, sadala augstfrekvences (no 1 GHz vai vairāk) signālu, kas vienlaikus spēj apkalpot vairākus gaismu izstarojošos elementus, kaskādes veidā sadalot informācijas signālu un pazeminot padeves frekvenci. Tādējādi sadales plate ģenerē nesošo augsto frekvenci, kas satur vairākas paketes ar mazāku frekvenci, un tiek nodota vadītājam, uz kura ir izvietoti vairāki pikseļi. Iekārta un vadības sistēma ir izveidota tādā veidā, lai augstfrekvences signāls, kas no komutācijas blokiem nonāk uz sadales platēm, saturētu laika reģistrus, tiktu sadalīts pa vairākām paketēm ar zemāku frekvenci, kas laika diapazonā ir pārveidotas uz nepieciešamo lielumu (1 līdz 8 MHz). Ar to tiek panākts, ka iedegas tikai nepieciešamais pikselis nepieciešamajā krāsā, nepieciešamajā intensitātē un nepieciešamajā laika vienībā.The information signal and power distribution boards, to which the conductors on the light emitting elements are connected, distribute a high frequency (from 1 GHz or more) signal capable of simultaneously serving multiple light emitting elements, cascading the information signal and reducing the feed frequency. The distribution board thus generates a carrier high frequency which contains several packets with a lower frequency and is passed to a driver on which several pixels are located. The equipment and the control system are designed in such a way that the high frequency signal from the switching units to the distribution boards contains time registers, is divided into several packets of lower frequency, which are converted into the required size (1 to 8 MHz) in the time range. This ensures that only the right pixel in the right color, intensity, and time unit is lit.

Vienlaikus ar iepriekš aprakstīto rezultātu izgudrojums nodrošina iespēju līdz minimumam samazināt strāvas vadītāju šķērsgriezumu. Neskatoties uz to, ka ģenerētā augstā frekvence padod strāvu vairākiem pikseļiem savā līnijā, patiesībā tā pikseļus iededz secīgi, vienlaicīgi neradot lielu elektroenerģijas patēriņu. Faktiski vadītāja šķērsgriezums pie šādas vadības sistēmas tiek aprēķināts, par pamatu ņemot tikai viena pikseļa, nevis pikseļu grupas, kas tam pieslēgti, elektroenerģijas patēriņu. Pievadošo celiņu šķērsgriezums var būt 0,1 līdz 0,2 mm vai pat vēl mazāks, kas tos padara cilvēka acīm praktiski nepamanāmus. Secīga pikseļu iedegšana notiek tik ātri (100 līdz 300 Hz vai vairāk), ka cilvēka acis to nespēj uztvert, bet viņš redz nepārtrauktu pilnvērtīgu attēlu.In combination with the result described above, the invention provides the ability to minimize the cross-section of conductors. Although the generated high frequency supplies power to several pixels on its line, it actually illuminates the pixels sequentially without generating a high power consumption. In fact, the cross-section of a driver at such a control system is calculated on the basis of the power consumption of only one pixel, not the group of pixels connected to it. The lead paths may have a cross-section of 0.1 to 0.2 mm or even smaller, which makes them practically invisible to the human eye. Sequential pixel illumination occurs at such a fast rate (100 to 300 Hz or more) that the human eye cannot perceive it, but he / she sees a continuous, full image.

Ar šo izgudrojumu ir panākta ne tikai izstrādājuma maksimāla gaismas caurlaidība, bet ari maksimāla uzticamība un izturība ar ne pārāk lielām ražošanas izmaksām un ērtu ekspluatāciju. Kopējā moduļu vadība tiek īstenota ar galveno kontrolieri. Galvenajam kontrolierim ir ieeju kopums, vēlams visu populāro formātu, piemēram, Composite, Component, VGA, HDMI, DVI, SDI, HD SDI utt., nodrošinot iespēju uz gaismu izstarojošajiem moduļiem novadīt pilnkrāsainu dinamisku vai statisku attēlu no dažādiem videosignāla avotiem (datora, DVD, videokameras u.tml.). Signāls ar galvenā kontrolieri tiek nosūtīts uz komutācijas blokiem, kuriem ir virkne informācijas izvadu ar diferenciāliem pastiprinātājiem, kas dod iespēju palielināt informācijas līniju attālumu līdzThis invention not only achieves maximum light transmittance, but also maximum reliability and durability with not too low production costs and easy operation. The overall control of the modules is implemented by the master controller. The master controller has a set of inputs, preferably all popular formats such as Composite, Component, VGA, HDMI, DVI, SDI, HD SDI, etc., enabling the light emitting modules to output full color dynamic or static video from various video sources (PC, DVD) , camcorders, etc.). The signal with the master controller is sent to the switching units, which have a series of information outputs with differential amplifiers, which allow to increase the distance of the information lines to

100 vai vairāk metriem. Tas nodrošina iespēju komutācijas bloku izvietot nevis tiešā gaismu izstarojošo moduļu tuvumā, bet lietotājam ērtā vietā. Komutācijas bloks var vadīt moduļu grupu, kas izvietoti atsevišķi vai secīgi kā horizontāli, tā ari vertikāli savienoti kopā bez atstarpēm.100 meters or more. This enables the switching unit to be placed in a user-friendly location not in the immediate vicinity of the light emitting modules. The switching unit can control a group of modules arranged individually or sequentially both horizontally and vertically connected together without spaces.

Elektroniskā signāla un elektropadeves sadales platēm, kas izvietotas ārpus moduļiem, ir diferenciāls uztvērējs, kas informācijas signālu uztver lielā attālumā, informāciju un elektropadevi sadala uz gaismas diožu pikseļiem moduļos un nosūta secīgu informāciju nākošajām signāla un elektropadeves sadales platēm. Informācija un elektropadeve no sadales platēm var tik nodota uz moduļiem no divām, trim vai četrām pusēm un tikt secīgi nosūtīta nākošajiem moduļiem, kas būtiski samazina nepieciešamo vadu un kabeļu daudzumu.The electronic signal and power distribution boards located outside the modules have a differential receiver which receives the information signal over a long distance, distributes the information and power to the LED pixels in the modules and transmits sequential information to subsequent signal and power distribution boards. The information and power supply from the distribution boards can be transmitted to modules on two, three or four sides and can be transmitted sequentially to subsequent modules, which significantly reduces the amount of wires and cables required.

Piedāvātie gaismas diožu moduļi var tikt plaši izmantoti dažādās jomās; tie var būt patstāvīgi izstrādājumi, tikt piestiprināti pie jebkurām plakanām, izliektām, ieliektām u.tml. virsmām; var būt citu izstrādājumu sastāvdaļa, piemēram, tikt piestiprināti pie jebkurām ēku fasāžu stiklojuma virsmām, tai skaitā, tik iebūvēti esošajās standarta hermētiskajās stikla paketēs vai stiklojuma mezglos, kalpot dinamisku par ēku arhitektūras apgaismojumu, tikt izmantoti par milzu videoekrāniem, uz kuriem tiek atveidota jebkāda informācija u.tml. Gaismu izstarojošie elementi ari var tikt izvietoti ari hermētiskā vai nehermētiskā, caurspīdīgā vai daļēji caurspīdīgā, cietā, elastīgā vai lokanā korpusā vai apvalkā. Korpuss vai apvalks nepieciešamības gadījumā var būt aprīkots ar rāmi vai pamatni, turklāt galveno kontrolieri, informācijas signāla un elektropadeves sadales plates un komutācijas blokus var izvietot ārpus minētās stikla paketes, korpusa vai apvalka.The proposed LED modules can be widely used in a variety of applications; they can be stand-alone products, be attached to any flat, curved, concave, etc. surfaces; can be part of other products, for example, to be attached to any glazing surfaces of building facades, including those built into existing standard sealed glazing units or glazing units, to serve as dynamic architectural lighting for buildings, to serve as giant video screens on which any information is rendered etc. The light-emitting elements may also be housed in an airtight or non-airtight, translucent or semi-transparent, rigid, resilient or flexible body or sheath. The housing or housing may, if necessary, be provided with a frame or base, and the master controller, information signal and power distribution boards and switching units may be located outside said glass unit, housing or housing.
