LCD Voltage Generation
Among the many ways to generate LCD voltage, two methods stand out above the crowd:
• resistor ladder
• charge pump.
The resistor ladder method, shown in
ages. This method uses inexpensive resistors to create the multi-level LCD voltages. Regardless
of the number of pixels that are energized the current remains constant. The voltage at point V3
is typically tied to V
The resistance values are determined by two factors: display quality and power consumption.
Display quality is a function of the LCD drive waveforms. Since the LCD panel is a capacitive
load, the waveform is distorted due to the charging and discharging currents. This distortion can
be reduced by decreasing the value of resistance. However, this change increases the power
consumption due to the increased current now flowing through the resistors. As the LCD panel
increases in size, the resistance value must be decreased to maintain the image quality of the
display.
Sometimes the addition of parallel capacitors to the resistance can reduce the distortion caused
by charging/discharging currents. The capacitors act as charge storage to provide current as the
display waveform transitions. In general, R is 1 k
200 k .
