Abstract
A compact integrated gate driver using metal‐oxide TFTs is proposed for Micro‐LED display. The positive pulse generation module (i.e. Scan driver) and negative modules (i.e. Emit driver) are located at different side of the Micro‐LED display, respectively. While Emit signals are re‐used for low‐level‐maintaining of the Scan module, the gate driver design can be much simplified and area occupation of the single gate driver can be reduced to 90 μm(length)× 245 μm(height), while the length of conventional designs exceeds 1000 μm. The simulation results of cascaded gate driver show that the rising time and falling time of the circuit are reduced to 1.3 μs and 2.1 μs, respectively, with the gate loading of 1.5 kΩ and 150 pF.
