The present invention relates to a backlight unit of a display device. The backlight unit is structured to have no light guide plate, and can include a reflecting plate, which is arranged on the inner surface of a cover bottom, and which has a sloping surface, and a light-collecting lens, which collects light from an edge light source portion. A light-absorbing pattern is arranged on at least one of an optical sheet, a diffuser plate, and the reflecting plate using such a configuration that the density of arrangement of the light-absorbing pattern is largest on a light-input portion and decreases towards an anti-light-input portion, or using such a configuration that the light-absorbing pattern is formed only on a flat surface of the reflecting plate, near the light-input portion, thereby providing uniform light throughout the entire display panel.

The virtual model control system has an input device configured to provide input information for formation, movement or transformation of a virtual model; a control device configured to form the virtual model based on the input information received from the input device, move or transform the virtual model, form a plurality of physical particles at the virtual model, form contact point information therefor, and move the plurality of physical particles to update the contact point information; an output device configured to output the virtual model to the outside. When the plurality of physical particles penetrates into another virtual model in the virtual space, the control devices update the contact point information so that the penetrating physical particles are rearranged at an outer side of the another virtual model.

A space registration system includes a display apparatus, an image sensor, a processor, and a plane mirror. The display apparatus has an inherent display coordinate system which defines a coordinate of the virtual space. The image sensor has an inherent sensor coordinate system which defines a coordinate of the real space. The processor analogizes a transformation equation of the sensor coordinate system and the display coordinate system by means of symmetry of an incidence angle and a reflection angle of light with respect to the mirror surface, compares a coordinate of the reflection image with respect to the display coordinate system with a known coordinate of the reflection image with respect to the sensor coordinate system, and adjusts the transformation equation of the sensor coordinate system and the display coordinate system.
