TFTs offer high colour saturation

Specially designed for high end industrial and medical devices, the Anders 3.5" QVGA TFTs offer optical specifications, three to five year guaranteed availability and an onboard lcd controller for the portrait model. The 3.5" QVGA displays are offered in either portrait or landscape orientation and both models include an integral white led backlight. They can be used in pin selectable parallel rgb mode or serial/parallel mcu mode, with no external lcd controller required for mcu mode in the portrait model. In the case of the landscape, rgb I/F model, an SPI interface is provided to allow access to the display's internal control registers where required. The amorphous silicon-based TFT displays have been developed for use within an extended -30 to 85°C temperature range and because they are thin and lightweight, are suitable for a variety of industrial and medical applications, such as industrial control and automation and medical diagnostic devices. According to Anders, the displays offer high colour saturation, high brightness (450 cd/m2 for portrait model, 500 cd/m2 for the landscape model), high contrast (portrait – 400:1, landscape – 500:1), 262K colours, and ultra-wide viewing angles of 150°, left to right.
