In common driver application mode, this block generates the shift clock (LK) for the common data Bi-directional shift register. Determines the direction of segment data shift, and input data of each Bi-directional shift register. In 4-bit segment data parallel transfer mode, data is shifted by a 4-bit unit. In common driver application mode, data is transferred to the common data shift register directly, which disables this block. ontrols the clock enable state of the current driver according to the input value of enable pin ( or ). If enable input value is Low, every clock of the current driver is enabled and the clock control block works. But if enable input is High, current driver is disabled and the input data value has no effect on the output level. o power consumption can be lowered. ontrols the output voltage level according to the input control pin (M and DIPOFFB) (refer to PIN DERIPTION). tores output data value by shifting the input values. In 1-bit serial interface mode application, all 80 shift clocks (K) are needed to store all the display data. But in 4-bit parallel transfer mode application, only 20 clocks are needed. In common driver application mode, this block does not work. In segment driver application mode, the data from the 20x4-bit segment data shift register are latched for segment driver output. In single-type common driver application,1-bit input data (from DL or DR pin) is shifted and latched by the direction according to the signal input. In dual-type common application mode, 80-bit registers are divided by two blocks and controlled independently (refer to NOTE 3). Voltage level shifter block for high voltage part. The inputs of this block are of logical voltage level and the outputs of this block are at high voltage level value. These values are input in to the driver. elects the output voltage level according to M and latched data value. If the data value is High the driver output is at selected voltage level (V0 or V5), and in the reverse case the driver output value is at the non-selected level (V12 or V43). In segment driver application mode, non-selected output value is V2 or V3. and when in common driver application, this value becomes V1 or V4. OM/EG EG EG OM/EG EG OM/EG EG EG 13
