Abstract
In a device for mounting a liquid crystal display (LCD) to a circuit board, a holder is positioned between the LCD and the circuit board and a cover member positioned around the LCD and holder is secured to the board. The LCD is recessed slightly within the cover member and is exposed through the cover at a display opening. To compensate for the recess of the LCD within the cover member, an optically clear lens is positioned with its lower surface in contact with the LCD and upper surface extending outwardly through the display opening. An image of the alphanumeric characters displayed by the LCD is projected on the outer surface of the lens of create an optical illusion of the display characters at the surface of the cover.
