If you want to drive LED strips, there is not much point in trying to reuse TM1637 which isn't designed for that. Without knowing how many LEDs, how are they going to be connected, what type of LED strip ("dumb" one, "neopixels", whatever), what current/voltage, etc. it is impossible to tell you whether uln2005a or whatever else will work. Draw some diagrams so that we know what you are trying to do, people don't read minds here.
