Tokyo, Japan NEC LCD Technologies, along with its sales and marketing channel in the Americas, NEC Electronics America, Inc., will begin shipping samples of a 4.1-inch (10.6 cm-diagonal), thin-film transistor (TFT) liquid crystal display (LCD) module in October 2007
Incorporating low-temperature poly-silicon (LTPS) technology, the NL8048HL11-01B module features wide video graphics array (WVGA) resolution that produces high-quality pictures on portable devices such as ultra-mobile personal computers (UMPCs) and portable multimedia players (PMPs), and on display devices for various small-size broadcasting equipment.
The LCD module features higher density due to greater integration. The module integrates
peripheral circuits including a gate driver, onto the TFT-LCD glass substrate, which reduces the peripheral wiring and the number of connections with external circuits. This translates into a high pixel density of approximately 227 pixels per inch (ppi), allowing characters and images to be clearly reproduced on the screen, said NEC.
The 4.1-inch module also delivers a high luminance of 350 candelas per square meter (cd/m2), and a wide color gamut of 72 percent (NTSC ratio). In addition, 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, capable of displaying 16.77 million colors simultaneously, attains precise color reproduction and smooth color gradation by taking full advantage of the wide range of colors, said NEC.
The module is also 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 also is offering a 4.3-inch (11 cm-diagonal) color TFT LCD module, part number NL4827HC19-05B, that boasts high luminance of 500 cd/m2 and wide quarter video graphics array (WQVGA) resolution.
Availability: Samples of the 4.1-inch NL8048HC11-01B and NL4827HC19-05B will start sampling in October 2007.
