How is a pixel array read, such as in a LED TV, digital camera, microbolometer, etc. All of these things have an array of pixels that either transmit or receive. Each pixel must be read somehow, is this done with a multiplexer and do you need more and more multiplexers the more pixels you have. How many analog outputs does a multiplexer have? If you have a lot of pixels would you have to have multiplexers that are reading other multiplexers or just one big mulitiplexer would make more sense since your scanning an array. So then the analog outputs of the multiplexer would then connect to a micro controller and presumably the controller could tell an LED screen which scan goes in which LED pixel. So say the multiplexer scans sensor 11 and sends it back in a micro second or less the micro controller then displays that signal in the LED screen 11. So the controller would have to know the scan order to know where to display. Is this correct thinking? Are there solid state lab companies that can take a design and make a chip for you as a proto type?
