A 7-inch WVGA TFT display module from Anders Electronics combines excellent visual characteristics with an extended operating temperature range of -30°C to +85°C. The device is particularly well-suited for use in equipment that requires excellent readability while coping with harsh climatic conditions. These include outdoor and industrial applications such as portable information terminals, field-test equipment, automotive, plant machinery and access-control systems. The 800xRGBx480 pixels (WVGA) TFT LCD module uses amorphous silicon transmissive LCD technology and an LED backlight to achieve typical brightness levels of 500cd/m2 and a contrast ratio of 400:1.
A left-right viewing angle of 140° further underlines the display’s adaptability in real-world industrial applications. Capable of displaying up to 262,000 colours, the display module features an integrated low voltage differential signalling (LVDS) interface. The module’s mechanical attributes also ease the designer’s task: with an overall thickness of 7.95mm, it provides greater flexibility in terms of physical positioning within the end system. Designed for use with a 3.3V power supply, the module provides an active viewing area of 152mm x 91mm. Typical LCD current is 150mA, while the LED backlight requires a 100mA constant current source.
