  • Backlight unit and liquid crystal display device using said backlight unit
    Patent number: 9097934
    Abstract: In the disclosed backlight unit, multiple LEDs are arranged as a light source at prescribed intervals on a substrate in a rectangular ring. Light irradiated from the LEDs is diffused through a lens, a prism plate and a diffusion plate, and is transmitted to a liquid crystal panel. There are roughly V-shaped concavities in the incidence surface of the lens, and triangular cross-section prisms for diffusing incident light are further arranged on the incidence surface of the prism plate. The LEDs are arranged on a highly thermally conductive LED cooling pattern, and the LED cooling pattern is in contact with a heat-dispersion housing. For that reason, heat emitted by the LEDs is conducted from the LED cooling pattern to the housing and dispersed to the ambient air. By this means, the backlight unit can save energy and be more compact.

  • Display device
    Patent number: 9078341
    Abstract: An upper frame covers a periphery of a liquid crystal display panel, and a cover plate is bonded onto the upper frame and an upper polarizing plate of the liquid crystal display panel. A step is formed on the cover plate in a portion where the upper frame is bonded to the cover plate. This can reduce a thickness of resin between the upper polarizing plate and the cover plate, thereby reducing an extrusion of the resin in between the cover plate and the upper frame. Thus, a chamfer on a lower side of the cover plate can be reduced in size, and stray light from the lower side of the cover plate can be prevented. This can prevent a white line around a screen.
