The 26 cm (10.4 inches) diagonal display area contains 640 ´ simultaneously. NL6448CC33-30 is a backlight-less model. Therefore, it is easy for customers to make own backlight and to get necessary brightness. 480 pixels and can display 262,144 colors FEATURES • Backlight-less • High contrast, wide viewing angle and wide color gamut • Smooth polarizer surface • 6-bit digital RGB interface • Data enable (DE) function • Variable gamma control • Reverse scan capability • Wide temperature range APPLICATIONS • Display terminals for control system • Monitors for process controller • Industrial PC The information in this document is subject to change without notice. Document No. MA990224 (Version 2) Date Published February 1999 P Printed in USA www.DataSheet4U.net © NEC Electronics Inc,1999 www.DataSheet4U.net NL6448CC33-30 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. 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 a 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.

Measured at the center of display area (Front side) Guarantee the optical characteristics at 25 degree C only. No condensation In case of that the module is exposed at high temperature in operation or storage, the polarizer film may peel off from the panel in the edge of the display area. It is recommended not to use the module under such environment continuously. It is estimated that the polarizer may peel off after the operation at 85 degree C with 120 hours in accumulation. 5. Incident light (Backlight) should be located from CF(Color Filter) side only. 6. Avoid to use the module in the environment which the strong light exposes the module surface directl.
