Abstract
A display module (100) includes a light pipe (140), a liquid crystal display (LCD) module (130), a lens cover (110), and a gasket (120), which are mated together to form a sealed assembly. The LCD module (130) and gasket (120) are captured between the lens cover(110) and light pipe (140), such that the gasket (120) provides a seal between the lens cover (110) and the LCD module (130). Preferably, the gasket (120) has at least one integrally formed button (122) that protrudes through a buttonhole (112) on the lens cover (110) to provide for external actuation of a switch (152) within the display module assembly (100).
