True colors shine through with Optrex LCDs

Optrex America touts that its new series of SVGA and XGA industrial TFT LCD modules, incorporating Natural Color Matrix (NCM) technology, delivers true color fidelity, optimum color balance and excellent image quality.

The patented NCM technology, developed by mitsubishi electric and already proven in electronic projectors, is now being incorporated into Optrex's 8.4-inch to 15-inch diagonal digital TFT LCDs for flat panel displays.

The company said NCM technology utilizes a color transformation algorithm, implemented in hardware, which provides real-time, on-the-fly processing, on a pixel-by-pixel basis, to precisely match the colors specified in a data source. This enables reproduction of even subtle colors such as pastels and flesh tones, according to the company.

In addition, NCM technology provides independent control of six colors without one color influencing any of the others. It supports 18-bit and 24-bit color and full motion video, and compensates for any color shifts caused by LCD components such as CCFLs and optical films.

The technology also delivers several other key advantages. For instance, it doesn't require a significant amount of LCD driving voltage, large amounts of circuitry or memory-intensive resources. The NCM algorithm is implemented in a small portion of the LCD's timing controller (TCON) and requires only a small amount of ROM.

Conventional color management techniques handle hue, saturation and intensity (HSI) as a single entity, without separating the chromic (H) and achromatic (SI) aspects of the data, unlike NCM, which provides independent control over the chromatic and achromatic characteristics, so the brightness level of one color on a transmissive LCD doesn't impact the other colors.

Optrex TFT LCD modules equipped with Natural Color Matrix technology include an 8.4-inch XGA module (P/N T-51639D084J-FW-A-AB), a 10.4-inch SVGA module (P/N T-51944D104J-FW-A-AA), a 12.1-inch SVGA module (P/N T-51866D121J-FW-A-A), and three 15-inch XGA modules (P/N T-51863D150J-FW-A-AA, T-51863D150J-FW-A-AB and T-51863D150J-FW-A-AD).

The company also notes that the new TFT LCDs with NCM, while offering critical performance enhancements, will not come with a significant increase in price as compared to standard non-NCM versions. Suitable applications include point-of-sale displays in markets such as fast food and retail, gaming applications, test and measurement instrumentation, diagnostic and imaging equipment, and automotive interior displays.

Pricing for the LCDs with NCM technology starts at $258.40 for the T-51866D121J-FW-A-AA 12.1-inch SVGA module in OEM quantities.
