Note 1) Connect stabilizing capacitors to the TESTTA1, TEST 2, and TESTA4 panel as required for the display quality of
the panel and voltage consumption (0.1
μ
F, characteristic B). Otherwise, adopt 1
μ
F, characteristic B.
Note 2) Place a shot-key diode (VF = about 0.4V/20mA, VR >=30V).
Note 3) Wiring from GND or VGL to the shot-key dioode must be 10
or less.
Note 4) Capacitors are not required when VCOMG = 0 (VCOML = GND).
