  • Liquid crystal display module
    Patent number: 10126489
    Abstract: An LCD module comprises an LCD panel and a backlight unit. The LCD panel has a front face and N sides (where N>2). The backlight unit comprises a frame, a light guide and a reflector. The frame has a front face, a rear face, N sides and a central aperture and the LCD panel is attached to the front face of the frame such that a first of the N sides of the frame is flush with a first of the N sides of the LCD panel. The light guide is positioned within the central aperture of the frame. The reflector covers the rear face of the light guide and some or all of the rear face of the frame and is attached to at least a part of the first side of the frame and to at least a part of the first side of the LCD panel.
