P‐11: A Novel 5T2C LTPO Pixel Circuit for MicroLED Display with Simultaneous Compensation and Programming

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.
