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

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. .

2. Glass cover for LED display message board?

Plexiglass

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.
