초록

We propose a new 5T2C pixel circuit for micro light-emitting diode (μLED) mobile displays. The 5T2C circuit is based on low-temperature polycrystalline silicon and metal-oxide (LTPO) thin-film transistor (TFT) technology. The proposed circuit is conducted by two methods; one is simultaneous threshold voltage compensation and data programming using double-gate oxide TFT and the other is digital driving using a stepwise signal. The simulation results show achieving full gray level and a current error rate below 2% under ±0.5 V threshold voltage variations of driving transistor and emission transistor.
