A package device has a packaging box and shock-absorbing members. The packaging box accommodates a display device main body with an exterior case that accommodates a display unit having a flat display panel and a drive circuit block. The shock-absorbing members are accommodated inside the packaging box so as to be disposed between the display main body and the packaging box at a top center and/or a bottom center. The shock-absorbing has first panel supporting parts that support the exterior case, and second panel supporting parts positioned on a display surface side of the display panel. The second panel supporting parts extend toward a center of the display panel from the first panel supporting parts so that gaps are formed between the display panel and the packing box. The shock absorbing members can effectively prevent damages to the thin display device due to mechanical shocks received during transportation.

Package device for thin display device

A projection display device includes a condensing unit and a shading unit. The condensing unit condenses light emitted from a light source to form a condensed spot on a color wheel. The shading unit, when a size of the condensed spot on the color wheel has increased due to an increase in light emission of the light source, shades a portion of the light passing through the color wheel corresponding to the increased size.

Sequential color display device including light shading means

A field sequential color display device includes a color wheel assembly. The color wheel assembly has a color wheel which is divided into a plurality of color regions and a motor for rotating the color wheel. The motor contains a sensor for detecting rotation of the motor and the sensor outputs at least one pulse per one revolution of the motor. The color wheel assembly also has a spatial light modulator for displaying image data that is driving in synchronization with the pulse output by the sensor.
