Diminutive Display

Transmissive 6.5-inch TFT LCD delivers space-efficient solution.

Toshiba Electronics Europe has expanded its family of active matrix thin film transistor (TFT) liquid crystal displays with the introduction of a space-efficient transmissive 6.5-inch (17cm) product. The display, which combines good performance with compact module size, is suitable for industrial control, warehousing systems, electronic point-of-sale (POS) terminals, ticket and information kiosks, medical systems, test and measurement equipment, and other applications where a clear quality colour display is required but space is limited.

Developed by Toshiba Matsushita Display Technology Company (TMD), the LTA065A041F display offers a 640 x 480 (VGA) pixel resolution and a viewing area of 5.18 x 3.88in (131.52 x 98.64mm). Module dimensions are 5.94 x 4.54 x 0.39 inches (151.0 x 115.5 x 10.0mm) and the display uses an RGB colour filter array to provide up to 64 grey shades per colour for a total of 260K colours. It has a built-in cold cathode fluorescent lamp (CCFL) backlight.

Commenting on the launch of the display, Marc Parsons, European business development manager for LCDs at Toshiba Electronics Europe, said: 'The addition of this 6.5-inch VGA display broadens our TFT LCD portfolio with a space-efficient solution for a wide variety of industrial, test and measurement, retail, and medical applications. Furthermore, in accordance with our industrial LCD strategy, we plan to supply this display for the next three years, subject to sufficient demand and the availability of components.'

The LTA065A041F offers typical brightness levels of 400cd/m2 and a typical contrast ratio of 250:1. Typical viewing angle for the unit is specified as 90 degrees in the vertical direction (at 10:1 contrast ratio) and 120 degrees in the horizontal direction, ensuring clear image quality in circumstances where the viewer is unable to directly face the screen.

Based on a space-efficient chip on glass (COG) technology, the LTA065A041F features an integral LCD drive circuit that minimises the need for external components. Typical response times as fast as 25ms (Ton and Toff) ensure optimum image quality for the display of moving images.
