Notes
1. The minimum level of (VMH − VM) depends on (VM − VL); a lower level of (VM − VL) requires lower offset of VMH
referred to VM. A higher level of (VMH − VM) improves dynamic behaviour. A minimum level of
(VMH − VM) = 2.5 V + 0.2 × (VM − VL) should be maintained.
2. Row outputs tested one at a time.
3. (VH − VL) = 37 V; VMH = VH; (VDD − VSS) = 2.8 V; VM = -V----H----2-+----V-----L- ; (VM − VSS) = 1.47 V.
4. fRCLK = 19.2 kHz; SVM = 0; ROWRES1 = ROWRES2 = HIGH; single line mode; all row outputs open-circuit.
5. Frame inversion frequency fFI = 2---f--R×----C-1--L--6K---0-- .
