... DESCRIPTION NL6448AC33-18A 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. NL6448AC33-18A has a built-in backlight. Backlight includes long life lamps, which are replaceable. The 26 cm diagonal display area contains 640 NL6448AC33-18A is suitable for factory automation use, because luminance is higher, and viewing direction is selectable by switching display scan direction ...

... This way works when BRTHL and BRTL are opend. The range of input voltage between BRTH and GNDB is as follows. Minimum luminance ( 2.5 V Maximum luminance (100 %) : 1.2 V This module can not use the luminance control by a current, because GNDB is in contact with the frame.

... The display condition of the LCD module may be affected by the ambient temperature. The LCD module uses cold cathode tube for backlighting. Optical characteristics, like luminance or uniformity, will change in the progres of time. Uneven brightness and/or small spots may be observed depending on different display patterns.
