NEC To Sample New 4.1-Inch LCD Modules

NEC LCD Technologies, along with NEC Electronics America, today announced that they will begin shipping samples of a new 4.1-inch (10.6cm) thin-film transistor liquid crystal display module, part number NL8048HL11-01B, at the beginning of October. Incorporating low-temperature poly-silicon (LTPS) technology, the new module features WVGA resolution for portable devices such as UMPCs and portable multimedia players, and on-display devices for various small-size broadcasting equipment.

The main features of the new LCD module are as follows.

1. Higher density due to greater integration. NEC LCD Technologies has integrated peripheral circuits, including a gate driver, onto the TFT-LCD glass substrate, thereby reducing the peripheral wiring and the number of connections with external circuits. As a result, the LCD module achieves pixel density of approximately 227 ppi, allowing characters and images to be clearly reproduced on the screen, making for smooth transitions as the displayed images change.
2. High luminance and wide color gamut, even with high density. The 4.1-inch module boasts luminance of 350 cd/m2 and a wide color gamut of 72 percent (NTSC ratio). These features are realized by a combination of a high aperture ratio, achieved by the LTPS TFT, and optimization of the color filters, backlight system and cell design.
3. Smooth and precise color/grayscale reproduction. A 24-bit (8 bits each for RGB) source driver enables independent control of each RGB gamma value and achieves a gamma curve optimized for various purposes. The LCD panel is capable of displaying 16.77 million colors.
4. Touch panel, timing controller and DC-DC converter. The module is equipped with a touch panel, timing controller, and DC-DC converter that help manufacturers of portable information devices reduce development costs and lead time.

In addition to the 4.1-inch module, the company is also offering a new 4.3-inch (11cm) color TFT LCD module, part number NL4827HC19-05B, that boasts luminance of 500 cd/m2 and wide quarter video graphics array (WQVGA) resolution.

Samples of the 4.1-inch NL8048HC11-01B and NL4827HC19-05B are scheduled to be available for sampling in October 2007.
