Figure 3. Uniformity test of 8 × 8 active matrix (AM) transistor array.

Figure 3

(a) AM transistor array on printer paper with pre-printed information. (b) 64 transfer curves of one AM array automatically acquired using LabVIEW™. (c–e) Mobility, threshold voltage (VTH), and on/off ratio (log value) colormaps of the 64 transistors in the AM. Mobility mean value is 0.45 cm2V−1s−1 with a standard deviation of 0.05 cm2V−1s−1; VTH mean value is −4.7 V with a standard deviation of 1.5 V; On/off ratio has a mean value of 1.5 × 108 and standard deviation of 3.7 × 108.
