Note: 1.1. LD: latches the polarity of outputs and switches the new data to outputs. At the rising edge latches the POL signal to control the polarity of outputs. The pin also controls the switch of the line registers that switches the new data to output. The LD may switch at any time even if the line data are not completely full 1.2. OEV: Gate output enable-+ 1.3. CKV: Gate output clock 1.4. REV: Control signal are inverted or not When use this function, it’s need your system Tcon support. 1.5. EDGSL: Choose raising edge or falling edge to match the timing characteristic.

3. Power &Timing Characteristic Customer should follow our product power sequence , otherwise it would lead to display

abnormal. Please refer to the figures as below.

3.1. Power sequence



3.2. Timing characteristic (please take special effort on relationship of signal each other )
