DESCRIPTION

NL8060BC31-17 is a TFT (thin film transistor) active matrix color liquid crystal display (LCD) module comprising

amorphous silicon TFT attached to each signal electrode, a driving circuit, and a backlight.

NL8060BC31-17 has a built-in backlight. The backlight includes long-life-lamps and the lamps are replaceable

with a holder.

The 31 cm diagonal display area contains 800 × 600 pixels and can display 262144 color simultaneously. NL8060BC31-17 is suitable for industrial application use, because the viewing angle is wide and the luminance

is high. Also, the viewing direction is selectable either upper or lower side by changing scan direction.

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.

SUPPLY VOLTAGE SEQUENCE

The supply voltage for input signals should be the same as V

Turn on the backlight within the LCD

operation period. When the backlight turns on before LCD operation or the LCD operation turns off before the backlight turns off, the display may momentarily become white.

When the power is off, please keep

whole signals (Hsync, Vsync, CLK, DE, R0-R5, G0-G5, B0-B5) low level or high impedance.

Wrong power sequence may dam-

age to the module. The signal should not be down dur-

ing operation. Even if signal could recover, LCD module can not be operated correctly, the display may be un-uniformity. In case signal is down, V then turn V sequence.
