Recent developments in microLED display technology focus on a method that equips each pixel with a single microIC. Miniaturization of ICs is crucial for driving microLEDs. Instead of traditional two-dimensional transmission methods, we considered one-dimensional data transmission. To reduce the number of chip terminals, we adopted a data clock recovery approach that integrates data and clock lines, achieving miniaturization. This explanation details the circuitry that realizes this transmission method and the layout design of the circuit.
