A computer-implemented method for updating pixel arrays may include (i) displaying an image on an array of pixels via a set of pixel control modules, where each pixel within the array of pixels is communicatively coupled to a different pixel control module within the set of pixel control modules, (ii) receiving an instruction to update the image displayed on the array of pixels to a new image, (iii) identifying a pixel within the array of pixels that is in a different state in the new image than in the image, and (iv) updating the pixel to the different state by transmitting a signal from the pixel control module directly to the pixel that updates the pixel independently of additional pixels. Various other methods, systems, and computer-readable media are also disclosed.
