Why LED Displays instead of project, LCD, OLED
- Brightness
 





LED DISPLAY

Shaders

Printed Circuit Board (PCB): LEDs and Driver Integrated Circuits

Power Supply: AC to DC (Typically 4.5 or 5 VDC)

Receiver Card: Converts pixel data cable to LED drivers

Frame: allows tiles to physically connect together 

Modules / Tiles: All the parts: PCBs, Receiver Card, Power Supply, Frame


Processor: Video Input, LED data outputs. Pixel mapping, Monitoring


Daisy Chain - connect in and out

Receiving cards, will have 2 ethernet port. In and Out.


Common LED Screen Processors/Receiving cards

Novastar** very reliable


All of the screen have a pixel limit

Pulse and Modulation

Receiving cards ( needs to know how many lights on the led)

Serial Drivers on LEDs

LED wall Processor. 8 bit (more contrast)


4:4:4
color depth : (HDR10) what is the color modulation

How do physical presence function in a networked world?  The physical presence is often overseen when thinking of the networked world we live in. Flavors, smells, physical touch are all part of our daily lives in a metropolitan city. Community engagement is what helps social networks thrive. During Covid some online communities flourished . Could this possibly be  a result of  a decade and a half of using social media platforms and smartphones? To me the networked world will relay on the human social experience of proximity. For example influencers rely on their following to consume things outside of the virtual interaction but in the networked world the followers get in close proximity through consumer products, or even places that they were referred to by influencers.  The symbiotic relationship between physical and online experience will continue to feed off each other in the near future.  Create something that addresses the materiality and/or Web3 reading (...

What is the role of bias in creating technological tools? I think using technological tools is one of the easiest ways to access a larger demographic therefore it should be created by All TYPES of people. For the past 20 years we have become more and more dependent on the information we consumed and exchange in a tech environment. Bias is real and it wasn't until less than a decade ago that the conversation about bias and the impact on people life's started to become more of a central topic. Now more than ever we need to give tools to people that otherwise don't have a voice in development of said technologies. Also understanding that Bias cannot disappear from one day to another, it a long process and we need to keep the conversation and education going.
