8.5 Partial Display
Using PTLIN (partial in) command allows you to turn on the partial display (division by line) of the screen. This mode
requires less current consumption than the whole screen display, making it suitable for the mobile equipment in the
standby state.
8.6 Gray-Scale Display
This function represents gray-scale by frame modulating the gray-scale date written on the display data RAM. In the
256-out-of-4096 colors (8 gray-scale) display, you can specify display colors using the command.
Respective data on red, green and blue are converted to the display data to be specified by the parameters of RGBSET8
command, and then written to the DDRAM. Blue is displayed in 4 gray-scale.
8.7 Oscillation Circuit
S1G15G10 contains the oscillation circuit whose operation does not require any external part. The oscillation circuit
is enabled only when M/S = HIGH and CLS = HIGH. When the external clock signal is (CLS = LOW or M/S = LOW),
the clock is entered from CL pin.
8.8 Display Timing Generation Circuit
This circuit generates the timing signal for display (CL, FR, SYNC, CA, F1, F2, DOFF) using the clock from the built-
in oscillation circuit or the external clock.
It is also used to generate the clock to turn on the liquid crystal-drive power circuit.
When using S1D15G10 in multi-chip array, the display timing signal (CL, FR, SYNC, CA, F1, F2, DOFF) must be sent
from the master to the slave.
8.9 SEG Decoder Circuit
This circuit outputs the segment driver control signal based on display data for 4-page and the timing signal.
8.10 Liquid Crystal Drive Circuit
It outputs liquid crystal drive voltage. Responding to the decoder output signal and the display-timing signal, the
segment output pin outputs one of potentials V
