HV Buffer Cell (Level Shifter)
HV Buffer Cell works as a level shifter which translates the low voltage output signal to the required
driving voltage. The output is shifted out with reference to the internal FRM clock which comes from the
Display Timing Generator. The voltage levels are given by the level selector which is synchronized with
the internal M signal.
Level Selector
Level Selector is a control of the display synchronization. Display voltage levels can be separated into two
sets and used with different cycles. Synchronization is important since it selects the required LCD voltage
level to the HV Buffer Cell, which in turn outputs the COM or SEG LCD waveform.
