We have studied solvent effect on the uniformity of the performance of the organic thin film transistors (OTFTs) by inkjet printing using TIPS pentacene as an active layer. A 1,2,4‐trichlorobenzene and cyclohexanol were used to control the viscosity for TIPS pentacene printing process. The uniformity of the performance of the TIPS pentacene TFT was greatly improved.
