Abstract

The invention provides a 2D / 3D (two-dimensional / three-dimensional) switching stereo display device, a driving control device and a driving method thereof. The 2D / 3D switching stereo display device comprises a display panel, a light guiding device, a 2D / 3D display switching device, a touch screen and a touch screen driving device; the display panel, the light guiding device and the touch screen are placed in turn; the 2D / 3D display switching device comprises a driving module; the driving module is connected to the light guiding device and is used for driving the light guiding device; the touch screen driving device is connected to the touch screen and is used for driving the touch screen; the 2D / 3D switching stereo display device also comprises a driving control device; and the driving control device is respectively connected to the driving module and the touch screen driving device and is used for controlling the driving module and the touch screen driving device to work in a time-sharing mode, thereby driving the light guiding device and the touch screen in a time-sharing mode. The 2D / 3D switching stereo display device provided by the invention can be used for eliminating interference between the driving of the light guiding device and the driving of the touch screen.

Description

technical field [0001] The present invention relates to a 2D / 3D switching stereoscopic display device and its driving control device and driving method, in particular to a 2D / 3D switching stereoscopic display device capable of eliminating interference between the driving of a light guide device and the driving of a touch screen and its Drive control device and drive method. Background technique [0002] 2D / 3D display switching technology is a major trend of stereoscopic display devices, which specifically means that stereoscopic display devices can display images in 2D or 3D display modes under the user's request, including displaying 3D images in different areas on the display screen at the same time and 2D graphics. An important element in the 2D / 3D display switching technology is the light guide. The light guiding device is used to transmit light and can be controlled to allow light to propagate in different directions. Usually, the light guide device is arranged at a ...
