How Do I Design a Circuit for a Bi-color Led to Display Power?

simulate this circuit - Schematic created using CircuitLabThis curcuit will do it for you, assuming D1 is red and D2 is green. R3 specifies current through LEDs. The trick is that when D2 lights up, R1 makes voltage on D1 less than its forward voltage drop need to light it

How Do I Design a Circuit for a Bi-color Led to Display Power? 1

1. How to make voltage out controllable DC power supply that displays the voltage supplied using a LED display?

This would be a difficult project. You can use a LM350, but that will get you only 1.2 volts to 10 volts, working from the 12 volt supply. And only a few amps. (You do not say how much current you want) You may be able to use the unregulated voltage inside which may be 15 volts or so. But the supply could use a switching regulator that gets very complicated and difficult to modify. First thing you need to do is to trace out the schematic of the supply. Then measure voltages at critical points. Then examine the schematic with a view towards modifying it. Now the meters. You can buy digital panel meters. If you want to do your own design, again, that gets very complicated. You have to futz with precision resistors, A-D converters, clocks, display drivers. You might want to consider something simpler. Perhaps just the supply without the meters. You can get digital multimeters for a few dollars. .

3. Is 15.6” High Definition (720p) LED Display with TrueLife a good amount of display for a laptop?

yeah its pretty decent but keep in mind that 720p (although still high definition) is not as good as 1080p and you can get ALOT of very good, reasonably prices laptops with 1080p display off the top of my head, i think the asus ul30 does, and the rest of its specs are even better considering buying one myself

4. What is the pin layout of the LTD5721WY-K2 LED Display?

My guess it that it would be wired the same as the old Hewlett-Packard HDSP-5721. See package type "E" on the attached data sheet. Pin-out on page 2, schematic on page 3.#

5. Am planning to connect led display to program chip and get the picture in chip on screen how to do dat pls hlp?

I will give that a big HUH? A display will only display something that it can "understand" If you have a display that can decode ASCII codes, then it will display the appropriate characters that are sent to it. A graphic display can only display images that are sent to it in a format that it is capable of displaying. If you want to display a representation of what the bits in the memory are holding, that is different. That would require some software to represent it on screen.

6. Can someone tell me how to wire up a 7 segment LED display?

Firstly it is necessary to see whether these displays are ''common catode'' or ''common anode''. Well I have checked: they are common anode. You will see that in te keft fgure there are marked pine 1, 16, etc. The others must be derived from the right hand figure... But you cannot connect the anode to 5 and one or more cathodes to ground. It is necessary a current limiting resistor. I too have begun: my advice is that you boy some simple kit, you assemble it and stuty the circuit. Good luck

7. Under the changing circumstances, how will the LED display industry break through in 2021?

In 2020, the global LED Display industry will be mixed by the dual influence of the new crown epidemic and the international environment. The good news is that the deep cultivation in the Micro/Mini LED and high-definition video industries is gratifying; the worry is that the epidemic has led to a "broken chain" crisis in the supply chain, fluctuating prices of raw materials and chips, and prolonged delivery. Looking forward to 2021, what challenges and opportunities will the industry usher in? How will the LED display terminal market and supply chain break through their limitations in the era of channel changes, shrinking profit margins, continuous product segmentation, and accelerated brand diversification? What are the growth drivers of the first-tier market in 2021, and what are the methods and means for manufacturers to seek growth? It is the top priority of all LED display manufacturers. The current development trend of the entire industry is the giant stock market competition. The only driving force for growth in the market actually comes from end users. Who can take the lead in connecting more end users, who can break through the predicament, and this requires LED display manufacturers to take the lead in completing the optimization and upgrading of channels. After the [tempering" of the 2020 epidemic, the channels of the LED display industry are no longer simply [offline channels to win". Many LED display companies have cultivated, developed and consolidated the channel moat and offline dealer system for many years. We are facing new adjustments-online and offline integration has become a reality. However, for many traditional LED display distributors, how to better integrate online channels while maintaining stable offline performance and sustainable operations, and achieve upgrades in store purchase experience and after-sales service. For upstream manufacturers, how to ensure the stability and sustainability of dealer groups in the context of channel fragmentation and multi-polarization is also a major challenge.

7-segment LED Display with Multiple Digits
7-segment LED Display with Multiple Digits
Actually this is a very common arrangement. Each digit has its anodes connected together, and the segments for all digits have their cathodes connected. The controller enables one of the common anodes, drives the segments, and waits, then turns off the cathodes and moves on to the next common anode. This arrangement and control method is called multiplexing, and the linked article will give you a lot of information. The part in question is a common anode display, but common cathode displays are just as common.Multiplexing allows you to drive a large number of display elements with fewer wires than individual addressing, at the expense of a more complex control algorithm. You can go a step further by doing something called Charlieplexing which allows you to drive even more elements with less I/O if you can turn off the drivers (as opposed to just setting them high or low, which is the requirement for a multiplexed display controller).Now that you know it's called a multiplexed display, you should have no trouble finding all kinds of example circuits or microcontroller code fragments to implement it1.

How to convert a fluorescent fixture to led?There are loads of questions with answers on this site that address this question and loads of YouTube tutorials on how to do it. I prefer to remove the ballast, its wiring and the tombstones.Replace the tombstones with Non-shunted ones and wire directly to one tombstone. Use wire nuts to pigtail 18awg wire to your black and white ( line and neutral ) house wiring and wire them to the two wire inputs on the non shunted tombstone. ( ground to the metal fixtures body. )Use a direct wire or ballast bypass led tube. I do not see the point in powering a ballast if it is not needed other than for people who are not comfortable making the electrical changes. ( its a waste of power ).2. What led to feudalism and its development?Feudalism is a too-general term for political "systems" ranging from warlordism to manorialism. But I suppose every explanation must start somewhere.(1st-2nd c. AD) The Romans used an immense, standing (i. e. "permanently employed") army to fortify the perimeter of the Mediterranean basin. Their military expansion pushed the frontier to the most naturally defensible boundaries - the Rhine, the Alps, the Danube, the Euphrates - and held a permanent cordon there, while the interior of the empire collectively demilitarized and urbanized, all the while funding the hard "outer shell."(3rd-4th c. AD) This fell apart because the Romans failed to find a solid political foundation for their state. Real power rested with the army, and the army was controlled by its generals. With the political framework being a military dictatorship, a change in leadership meant that generals would start fighting each other. This meant withdrawing their troops from the frontier they were supposed to watch and moving against the empire's own heartland, creating repeated breaches in the military cordon keeping the empire's economy and population intact. Without a political will to serve the state - political power degenerating into the whims of these general-warlords - military service became increasingly outsourced to the infamous "barbarians" (Goths & other Germans), who became essentially mercenary troops for competing soldier-emperors, soon composing the effective bulk of the Roman army. As the watch on the frontier weakened, more barbarians entered the empire, becoming nuisances and military leaders in their own right. The need to efficiently draw resources from the populace, and the employment of mercenaries rather than conscripts, led to the legal binding of peasants to the land - the beginning of serfdom, which would in much of Europe remain until the 18th century. (5th-8th c. AD) The European political landscape assumed its final form as the barbarian warrior-bands proliferated within the empire. To gain their support, the emperors started handing out land as well as gold, bidding against both other emperors & the possible plunder of barbarian raids. This consolidated the classical medieval system: a number of barbarian dominions ruled by reges ("kings") acknowledging the nominal authority of a Roman emperor, their tribal military occupation superimposed over an older, urban network of cities and churches speaking Latin. The most important tribal leaders, i. e. those theoretically receiving their mandate to rule directly from the Roman emperor, were given the title rex by the Romans, after their old (and tyrannical) hereditary rulers of Rome. The Germans translated this to variants of the Germanic kuningaz/knig/king. These kings or chieftains were elected by their warriors, the free Germanic tribesmen who provided their military support. Whereas the Roman populace was still subject to their own law, and looked to the Emperor in Constantinople for political protection, the barbarian peoples lived under their separate Germanic law and generally had a separate religion from the Romans (paganism or the Arian Christian heresy).Lesser tribal leaders, i.e. those submitting to another barbarian king rather than the emperor, were called Dukes, an old Roman word for provincial commanders. Internally, their "duchies" operated as "kingdoms" on a smaller scale. Many kingdoms were composed of several duchies, i.e. a confederation of tribes, who periodically elected a king or "Grand Duke" from among their number.(9th-10th c. AD) The landmark event of the middle ages was the rise of Charlemagne (r. 768-814), a king of the Franks who conquered Italy and was proclaimed Emperor himself. He was not remarkable because he was the first barbarian ruler to equal a Roman emperor in power - Theoderic the Great (r. 475-526) had ruled probably a larger and wealthier realm including Spain & Italy and spanning into Africa centuries previous (see first map). Charlemagne was remarkable for changing the rules of the political game, setting the stage for the feudal politics of later Europe.Imitating the Romans, Charlemagne ordered the destruction of all fortifications ("castles") in his lands. Instead of letting his subjects arm themselves to survive raids from surrounding pagan peoples, he led active forays of subjugation against all neighbours, forming a thick buffer of subject, converted peoples around his borders. He recreated an old Hellenistic bit of administration, giving his personal companions (comites, or counts), the mounted and armored men at arms, small parcels of land whose income they would use to support themselves and guard vulnerable frontier areas.His alliance with the Roman Papacy created a new role for himself as Emperor, or leader and ruler of the Christian world. His reforms began the (very) long process of decline of the old tribal institutions, the barbarian and religiously schismatic tribal duchies and kingdoms, and their replacement with a more centralized and autocratic model in which the king ruled directly via laws and counties, where a literate network of communication could make laws proclaimed in Rome or Aachen heard and felt from the Baltic to the Pyrenees. (11th-15th c. ) The transformation was by no means instantaneous. By the middle of the 10th century, the Viking and Arab incursions into Europe had seen to it that there were few coherent, stable kingdoms, only an immense feudal patchwork of competing dynasties. Charlemagne's empire had collapsed, and would be restored by Otto the Great (r. 936-73) as the so-called "Holy Roman Empire." The pattern would remain the same: a central Emperor - fulfilling the same universal role as the old Roman emperor to the barbarian tribes, i.e. the political head of Christendom.Surrounding "kingdoms" - with new ones formed, under German-Roman pressure and political patronage, in previously pagan Eastern Europe and Scandinavia - were at this point in time legal "tents" covering several local families and tribes, with the pre-eminent among them being elected and/or styling themselves king, a position placing them on the "diplomatic table" headed by the Emperor. The Holy Roman Empire itself was one such, uniting the old Roman lands of Italy with the tribal duchies of Germany, one of whose dukes/tribal leaders became Emperor by going into Italy to claim the Pope's blessing.The smaller "counties" once created as tools of administration became hereditary. Over centuries, politically savvy families grew their "hereditary lands", refining political administration all the while, and made their counties the nuclei of later political entities. In time, they grew strong enough to claim or solidify the nominal umbrellas of "kingdoms" into early modern states. In this fashion the counts of Paris came to rule France, the counts of Habsburg formed the Archduchy of Austria and then came to rule the Empire, while the counts of Anjou seized England, or the marcher-counts of Brandenburg became kings of Prussia and then Germany.As these new, more efficient polities gained critical mass, the large regions of Europe still divided among local princes - Germany, Italy, Ireland, the Balkans, etc. - were left behind, and became chessboards for the wars of the Great Powers. The various titles - count, duke, king, etc. - became increasingly less important. The king of France no longer saw himself as holding a fiefdom for the Emperor, and had the means to effectively eliminate semi-independent tribes in his borders. In this fashion, noble families were turned into the privileged servants of great states - holding onto titles as baroque memorabilia of their old independence3.
