EM73A88 serial (A83,983) used for large panel LCD need to adjust the connecting circuit to improve the performance. Fig-1 is the standard connecting method. Fig-1 Fig-2 104 VA VB 104 104 104 104 104 VA 104 VB 200K V1 474 V2 474 V3 474 V4 474 V5 474 V1 V2 V3 V4 V5 If the LCD panel is larger than 1.5 x 1.5 cm^2 , change the connecting circuit as fig-2. This way will make the V1~V5 more stable but the LCD will be darker than normal. By the way, this will increase the power consumption about 4uA. 1
