DATA SHEET TFT COLOR LCD MODULE NL3224AC35-10 14 cm (5.5 inches), 320 × 240 Pixels, Full color Incorporated backlight with inverter NL3224AC35-10 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. NL3224AC35-10 has a built-in backlight. The 14 cm diagonal display area contains 320 × 240 pixels and can display full-color (more than 16 million colors) simultaneously. FEATURES • High luminance • Analog RGB interface • Reversible horizontal and vertical scanning • Incorporated edge type backlight with Inverter • Smooth polarizer surface APPLICATIONS • TV monitors • Video games • Monitors for process controller Document No. EN0440EJ1V0DS00 Date Published May 1999 P Printed in Japan © 1999 NL3224AC35-10 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.

If higher than 0.3 V is input to signal lines, the internal circuit will be damaged. b) The backlight power supply (VDCB) is not related to the power supply sequence. However, unstable data will be displayed when the backlight power is turned ON with no logic signals. d) Analog RGB input are independent from this power supply sequence. f) Apply VDCB 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.

CAUTION This figure is a mark that you will get hurt and/or the module will have damages when you make a mistake to operate. This figure is a mark that you will get an electric shock when you make a mistake to operate. This figure is a mark that you will get hurt when you make a mistake to operate CAUTION Do not touch an inverter, on which is stuck a caution label, while the LCD module is under the operation, because of dangerous high voltage. (1) Caution when taking out the module a) Pick the pouch only, in taking out module from a carrier box. (2) Cautions for handling the module a) As the electrostatic discharges may break the LCD module, handle the LCD module with care against electrostatic discharges. b) As the LCD panel and backlight element are made from fragile glass material, impulse and pressure to the LCD module should be avoided. c) As the surface of polarizer is very soft and easily scratched, use a soft dry cloth without chemicals for cleaning. d) Do not pull the interface connectors in or out while the LCD module is operating. e) Put the module display side down on a flat horizontal plane. f) Handle connectors and cables with care. g) When the module is operating, do not lose ECLK, Hsync, or Vsync signal. If any one of these signals is lost, the LCD panel would be damaged. h) Don’t push or rub the surface of LCD module please. If you do, the scratches or the marks like rubbing may left on the surface of the module. (3) Cautions for the atmosphere a) Dew drop atmosphere must be avoided. b) Do not store and/or operate the LCD module in a high temperature and/or high humidity atmosphere. Storage in an Electro-conductive Polymer Packing Pouch and under relatively low temperature atmosphere is recommended. c) This module uses a cold cathode fluorescent lamp. Therefore, the life time of the lamp becomes short conspicuously at low temperature. d) Do not operate the LCD module in a high magnetic field. (4) Caution for the module characteristics a) Do not apply the fixed pattern data signal to the LCD module at product aging. Applying fixed pattem for a long time may cause image sticking. b) The noise from the inverter circuit may be observed in the luminance control mode. This is not defects not malfunctions. 14 Data Sheet EN0440EJ1V0DS00 NL3224AC35-10 (5) Other cautions a) Do not disassemble and/or reassemble LCD module. b) Do not readjust variable resistors nor switches etc. c) When returning the module for repair or etc., please pack the module not to be broken. We recommend the original shipping packages. Liquid Crystal Display has the following specific characteristics. There are not defects or malfunctions. The display condition of LCD module may be affected by the ambient temperature. This module has cold cathode tube for backlight. Optical characteristics, like luminance or uniformity, will be changed during time. Uneven brightness and/or small spots may be noticed depending on different display patterns.
