Combining frame size reductions with integrated power sources and extended lifetime backlights, the latest CSTN colour LCD modules from Arrow save space, minimise component count and reduce cost without compromising picture quality, brightness, viewing angle or reliability. The Kyocera V series comprises 4.7, 5.7 and 6.2in passive matrix colour LCD modules with frame sizes that are around 15% smaller than previous Kyocera products with the same screen areas. In addition, each module features a built-in DC/DC convertor that eliminates the need for an external LCD drive power source and a CFL backlight offering a 25% longer operational life.

Target applications for the modules range from industrial control and instrumentation to test and measurement equipment, medical devices and point of sale systems.

Both the 4.7in KCG047QV1AA and the 5.7in KCG057QV1DB are QVGA modules, whereas the 6.2in KCG062HV1AA delivers half VGA resolution.

The 4.7in module represents an ideal low-cost upgrade path to colour for designs currently using small, QVGA mono displays.

A high brightness of 350cd/m2 and a contrast ratio of 55:1 make the 5.7in module a suitable alternative for more expensive TFT solutions.

Brightness levels and contrast ratios for the 4.7 and 6.2in modules are specified at 160cd/m2 and 30:1, respectively.

All of the new displays feature a long-life, single tube CFL backlight with backlight lifetime ranging from 54kh for the 4.7 and 6.2in modules to 75kh for the 5.7in version.

Each display also offers onboard temperature compensation and can accommodate a 3.3 or a 5.0V logic source.

Kyocera has been able to reduce the frame size of the new displays through a combination of improved driver IC mounting methods and the positioning of the LCD circuitry on the rear of the module, which allows the glass to be mounted in a symmetrical frame.

As a result, maximum respective frame dimensions for the new 4.7, 5.7 and 6.2in modules are just 122.4 x 90.0 x 7.6, 144.0 x 104.8 x 12.7 and 174.2 x 73.4 x 7.6mm.
