Abstract

The invention discloses a three-dimensional display device and a method for controlling the display brightness of a display screen of the three-dimensional display device. The three-dimensional display device overcomes the defects that when the display screen of the traditional three-dimensional display device rotates relative to a looker, the watching experience of a looker is affected as the display screen twinkles; The method comprises the following steps of: obtaining the rotation angle of the display screen around the center; obtaining the side-play amount of the looker corresponding to a flat surface parallel to the rotated display screen under the rotation angle; and judging that when the looker is located in an adjustment interval of the rotated display screen according to the side-play amount, adjusting the display brightness of the display screen to be a preset value. The method effectively solves the problem that when the three-dimensional display device rotates relative to the looker, the display screen twinkles.

Description

technical field [0001] The invention relates to stereoscopic display technology, in particular to a stereoscopic display device and a method for controlling display brightness of a display screen of the stereoscopic display device. Background technique [0002] At present, the display technologies commonly used in stereoscopic display devices are mainly two types of lenticular grating and slit grating. Due to the periodicity of the grating, when the position of the viewer relative to the display screen of the stereoscopic display device changes, especially when the position of the viewer toward the display screen of the stereoscopic display device changes, it may be more obvious that the display screen of the stereoscopic display device changes. Flickering changes from dark to light or from light to dark (ie moiré). The reason for this flickering change is that relative to the stereoscopic display device, the viewer changes the position from one stereoscopic area to another...
