FUNCTIONS
[FUNCTION SELECT]
HOW TO USE THE FUNCTIONS
If CNTSEL is “L”, the above functions are valid. (CNTSEL is “H” or open, default values are valid.) After serial data
are transferred, the data is latched by CNTSTB. Once, the data is latched, the above functions are effective.
Please keep CNTSTB to be “L” during transferring data. Input data can be changed during power on, but LCD display
may be disturbed. When the serial data are changed, we recommend that the backlight power is off using BRTC
function.
Notes 1. The variable resistor for luminance control should be 10 kW type, and zero point of the resistor corresponds
BRTP signal
should be
"Open"
BRTP signal
is "Valid"
(5) Contrast control
(6) Sub-Contrast control
(7) Sub-Brightness control
This LCD module has following functions by serial data input (table 1)
(1) Display position control (VERTICAL)
(2) Display position control(HORIZONTAL): See table 6
(3) CLK delay control
(4) CLK fall/rise synchronous change
Set up the following items to work the above functions
(A) Expansion mode
(B) CLK counts of horizontal period
(C) CLK frequency range
Form
to the minimum luminance.
PWSEL="H"
or "L"
PWSEL="L"
Terminal
BRTH
Mating variable resistor: 10 kW
Luminance can be controlled by BRTP signal.
Refer to OUTSIDE CONTROL FOR LUMINANCE in detail.
Resistor
Voltage
R
Please connect BRTH and BRTL with the variable resistor discribed as follows.
BRTH is "0V", and BRTL input voltage controls brightness. When BRTL input
voltage is"1V", the luminance becomes maximum. And when BRTL input voltage
is "0V', the luminance becomes minimum.
