摘要： In a liquid crystal display device according to the present invention, an upper end portion of a lamp housing is fixed on a main supporter so that the lamp housing can be made to face a side edge of a light guide. Light that can cause bright lines is eliminated or minimized through absorption or scattering by a main supporter. The main supporter is also thermally insulating and is placed between the lamp housing and a liquid crystal panel. Further, a thermally conducting bottom cover is placed under the backlight. Therefore, heat generated from the lamp is effectively channeled away from the light guide to prevent liquid crystal panel deterioration. Still further, although the upper and lower surfaces of the light guide is tightly fit between the lamp housing and the main supporter, wrinkles on a sheet reflector are prevented because the sheet reflector is not stacked between the lamp housing and a lower surface of the light guide.

摘要： A liquid crystal display of improved contrast is provided. Image contrast is determined by the ratio of light from the display pixels that are in an on state to the light from the display pixels that are in an off state. The disclosed system improves on the image contrast by selecting the illumination direction and the panel orientation in such a way as to minimize the amount of light entering the viewing field that is due to scattered and/or diffracted light from the fine features of the display panel.
摘要翻译：提供了改善对比度的液晶显示器。图像对比度由来自处于打开状态的显示像素的光与来自处于关闭状态的显示像素的光的比率确定。所公开的系统通过选择照明方向和面板方向来改善图像对比度，以便使由于来自显示面板的精细特征的散射和/或衍射光而进入视场的光量最小化。
