NEC Introduces New 3.5-Inch LCD Module
NEC LCD Technologies introduced a new 3.5-inch (8.9cm) amorphous-silicon transflective TFT LCD module with QVGA resolution, part number NL2432HC22-45A, which features higher reflection properties than previous 3.5-inch transflective models that operate in both transmissive mode (using a backlight) and reflective mode (using available ambient light). The display is targeted for use in small, professional applications such as handheld terminals, as well as in personal digital assistant (PDA) and portable navigation device (PND) applications.
The new product incorporates NEC LCD Technologies' super-reflective natural light TFT (SR-NLT) technology, a proprietary technology that enhances LCD performance in outdoor lighting environments. In the reflective mode, the display module capitalizes on NEC's optimum LCD panel design to provide excellent visibility and viewing angle characteristics, even in outdoor daylight conditions. In addition, the module enables displayed information to be read when the backlight is off, even in an indoor lighting environment, thereby reducing power consumption.
Generally, portable information display instruments use either transmissive or transflective LCD modules. In both transmissive and transflective modules, the backlight consumes between 70 to 90 percent of the displays' total power consumption.
NEC LCD Technologies' new 3.5-inch module, developed in response to the demand for lower power consumption displays in portable applications, incorporates the company's proprietary SR-NLT technologies and newly optimized panel design. Thus, the new product has a high reflection ratio of 16 percent and a contrast ratio of 20:1 in reflective mode. The module also achieves improved viewing angle characteristics in reflective mode by diffusing reflection for wide-angle viewing. This allows for high visibility with the backlight turned off, whether under strong light conditions, such as outdoor daylight viewing, as well as indoor ambient light conditions.
