STRUCTURE AND FUNCTIONS
A color TFT (thin film transistor) LCD module is comprised of a TFT liquid crystal panel structure, LSIs for driving
the TFT array, and a backlight assembly. The TFT panel structure is created by sandwiching liquid crystal material
in the narrow gap between a TFT array glass substrate and a color filter glass substrate. After the driver LSIs are
connected to the panel, the backlight assembly is attached to the backside of the panel.
RGB (red, green, blue) data signals from a source system is modulated into a form suitable for active matrix
addressing by the onboard signal processor and sent to the driver LSIs which in turn addresses the individual TFT
cells.
Acting as an electro-optical switch, each TFT cell regulates light transmission from the backlight assembly when
activated by the data source. By regulating the amount of light passing through the array of red, green, and blue
dots, color images are created with clarity.

POWER SUPPLY DESIGN
(1) Please note that the supply voltage must not be applied while the control signals (SEL, UP, DOWN, EXIT,
LEFT, RIGHT and RESET) are connected to GND. Otherwise the module may cause malfunction.
(2) If the power supply voltage is applied while UP and DOWN are connected to GND, the input control signals
become ineffective mode. To reset this mode, turn off the power once and turn on the power while UP and
DOWN are connected to GND. Then, the mode will be released.
(3) Do not change MENUSEL setting while the module is operated.
MENUSEL selection (Hierarchical type or Toggle type) is set when the power supply voltage is applied.
(4) Inverter current wave
Inverter current wave is as follows.
1460 (mA)
0 (mA)
Duty
Luminance control frequency
maximum luminance control: 100 % (Duty)
minimam luminance control: 20 % (Duty)

Note 1. Even if the preset timing is entered, a little adjustment of the functions such as Horizontal period, CLKdelay and display position, are required. The adjusted values are memorized in every preset No.
Note 2. This module recognizes the synchronous signals with near preset timing of the frequency of HS, Vsync,
even in the case that the signals other than the preset timing that were entered. For instance, it is
displayed with presetting number 6 in the case of 640 × 480 dot, HS: 37.861kHz, Vsync: 72.809 Hz an
example).
Please note that using out of the preset timings may cause wrong magnification ratio,
unfitness of control functions or other improper display.
Note 3. The display color scale may be different between Sync on Green Input and others.
CONTROL FUNCTIONS
EXPANSION FUNCTION
Expansion mode is a function to expand the screen size in different resolutions. For example, VGA signal has
640 × 480 pixels. But, if the display data can be expanded to 1.6 times vertically and horizontally, VGA screen
image can be displayed fully on the screen of XGA resolution.
This module automatically recognizes the timing shown in “PRESET TIMING” as an expansion mode.
Please adopt this mode after evaluating display quality because the appearance in expansion mode may
become bad in some cases.
The followings show display magnifications for each mode.
