Small-Format TFTs Suit Harsh Automotive Environments


Kyocera introduces two small-format TFT modules with diagonals measuring 4.2 inch (10.66cm) and 5 (12.7cm) inch to expand its range of LCDs. Both modules are designed for use in harsh environments, such as outdoor remote controls, construction equipment, and anything that requires a wide operating temperature range.

The new 4.2-inch TFT LCD module (T-57152GD042H-LW-AAN) features a resolution of 480×272 pixels, brightness of 700 cd/m², a digital 18-bit RGB interface, a contrast ratio of 1200:1, and horizontal and vertical viewing angles of 160 degrees each. The design is based on automotive requirements and boasts an expanded operating temperature range of -30°C to +85°C and a storage temperature range of -40°C to 95°C. In addition, the anti-glare surface treatment improves readability in bright surroundings.

The new 5.0-inch (12.7cm) TFT module (T-55923GD050J-LW-ABN) is a portrait-mode display that features a resolution of 480×640 pixels. Optical characteristics include 800 cd/m² brightness and a 500:1 contrast ratio. The viewing angle amounts to 140 degrees horizontally and 110 degrees vertically. This module comes with a 24-bit digital RGB interface and has a wide operating temperature range of -30°C to +80°C.


“Portable outdoor devices are liable to fall down and are exposed to low temperatures, heat and humidity. Even in these conditions, they should always work reliably, and our components are designed for that purpose,” says Eberhard Schill, Manager Distribution and Marketing at Kyocera Display Europe GmbH.
