Small-format LCDs with increased temperature range for industrial applications

Latest from Kyocera is news of the expansion of its range of LCDs with two new small-format 4.2-inch and 5-inch TFT modules. Both modules are designed for use in harsh environments, such as outdoor remote controls, construction equipment and anywhere requiring a wide operating temperature range. The 4.2-inch TFT LCD module (T-57152GD042H-LW-AAN) features a resolution of 480x272 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 offers an expanded operating temperature range of -30C to +85C and a storage temperature range of -40C to 95C. In addition, the anti-glare surface treatment improves readability in bright surroundings. The 5-inch TFT module (T-55923GD050J-LW-ABN) is a portrait-mode display that features a resolution of 480x640 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 -30C to +80C, says the company. “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,” said Eberhard Schill, distribution and marketing manager, Kyocera Display Europe.
