5.7-inch TFT industrial displays usable from -30°C to +85°C

23 DECEMBER 2008

The two new 5.7-inch TFT displays, G057VN01 and G057QN01, from AU Optronics distributed by Gleichmann Electronics each feature a wide operating temperature range from -30°C to +85°C and low power consumption of just marginally more than 2 W. Both the model G057VN01 with 640 x 480 pixels (VGA resolution) and the G057QN01 with 320 x 240 pixels (QVGA resolution) are provided with a LED backlight, which also at low temperatures still guarantees an optimal light yield. A brightness of 400cd/m2 and a contrast ratio of 600:1, together with wide horizontal and vertical viewing angles of 140° and 120°, ensure good readability also under highly variable light conditions.
Furthermore, a “reverse scan” circuit enables a 180° rotated image representation. Thereby, gray level inversions, which commonly occur with TN technology when the screen is viewed at a certain angle, can be avoided. The G057VN01 and G057QN01 operate with 3.3 V supply voltage and have a response time of 35 ms. Due to their technical characteristics, both of the 5.7-inch TFT displays are ideally suited for use in vending machines, point-of-sale systems, ships, etc.
