LCD DISPLAY CIRCUITS
Oscillator
This is completely on-chip Oscillator and its frequency is nearly independent of V
DD
. This Oscillator signal is used in
the voltage converter and display timing generation circuit.
Display Timing Generator Circuit
This circuit generates some signals to be used for displaying LCD. The display clock, CL, generated by oscillation
clock, generates the clock for the line counter and the signal for the display data latch. The line address of on-chip
RAM is generated in synchronization with the display clock (CL) and the display data latch circuit latches the 104-
bit display data in synchronization with the display clock. The display data, which is read to the LCD driver, is
completely independent of the access to the display data RAM from the microprocessor. The display clock
generates an LCD AC signal (M) which enables the LCD driver to make a AC drive waveform, and also generates an
internal common timing signal and start signal to the common driver. The frame signal or the line signal changes the
M by setting internal instruction. Driving waveform and internal timing signal are shown in figure 10.
In a multiple chip configuration, the slave chip requires the CL, M and SYNC signals from the master. Table 11
shows the CL, SYNC, and M status.
