FULL-COLOR, MULTI-SCAN FUNCTION
INCORPORATED BACKLIGHT WITH INVERTER
DESCRIPTION
NL10276AC28-01E is a TFT (thin film transistor) active matrix color liquid crystal display (LCD) comprising amorphous
silicon TFT attached to each signal electrode, a driving circuit and a backlight. NL10276AC28-01E has a built-in
backlight with inverter.
The 36cm diagonal display area contains 1024 ´ 768 pixels and can display full-color (more than 16 million colors
simultaneously).
NL1276AC28-01E is a sucessor model of NL10276AC28-01.
FEATURES
• High luminance and Low reflection
• Analog RGB signals
• Contrast and brightness control function
• Multi-scan function: e.g., XGA, SVGA, VGA, VGA-TEXT, PC-9801, MAC
• Incorporated edge-light type backlight with inverter (Two long life CCFLs per lamp holder)
• Replaceable lamp holder (Part number: 141LHS08)
APPLICATIONS
• Engineering workstation(EWS), Desk-top type of PC
• Display terminals for control system
• Monitors for process controller

[FUNCTION SELECT]
Form
BRTP signal
is "Valid"
BRTP signal
should be
"Open"
Terminal
PWSEL="L"
PWSEL="H"
or "L"
How to adjust
Luminance can be controlled by BRTP signal.
Refer to OUTSIDE CONTROL FOR LUMINANCE in detail.
Resistor Please connect BRTH and BRTL with the variable resistor discribed as follows.
Voltage
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.
Notes 1. The variable resistor for luminance control should be 10 kW type, and zero point of the resistor corresponds
to the minimum luminance.
BRTH
R
Mating variable resistor: 10 kW
BRTL Maximum luminance (100 %) : R = 10 kW
Minimum luminance (30 %) : R = 0 W

FUNCTIONS
This LCD module has following functions by serial data input (table 1)
(1) Display position control (VERTICAL) : See table 3
(2) Display position control(HORIZONTAL): See table 6
(3) CLK delay control
: See table 4
(4) CLK fall/rise synchronous change
(5) Contrast control
(6) Sub-Contrast control
(7) Sub-Brightness control
: See table 5
} See table 9, 10 and COLOR CONTROL FUNCTION AND
GRAPHIC IMAGE
Set up the following items to work the above functions
(A) Expansion mode
(B) CLK counts of horizontal period
(C) CLK frequency range
: See table 2 and EXPANSION FUNCTION
: See table 7
: See table 8
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.
