摘要： The embodiments of the present invention provide a parallax barrier panel, a display substrate, a display device, an electronic equipment and a display method. The parallax barrier panel includes a switchable array and a control module. The switchable array is used for forming a parallax barrier. The control module is used for adjusting the direction of the parallax barrier based on the interocular direction of an observer. By adjusting the direction of the parallax barrier based on the interocular direction of the observer, an ideal three-dimensional display effect can always be provided to the observer during three-dimensional display.

摘要： A portable CAVE automatic virtual environment system. The system uses a light weight collapsible frame with an overhead beam that is raised and lowered via a winch and cable. Ultra-short throw projectors are attached to the overhead beam at its lowest position and are raised to their functional position where they are automatically configured to aim at one of the included screens. The projectors display imagery on the screens that form a space around the user. The system auto-calibrates to align the projected imagery to the screens to form a seamless display across all screens. The invention significantly decreases the time and labor to set up and calibrate a CAVE system and collapses into folded parts for easy transport and storage.

摘要： A hand-held turbine cleaning tool includes front and rear housings coupled to each other, an outlet at one end of the tool, and a top of the tool at an opposed end. The outlet is directed in a first direction away from the top. An inlet is disposed between the outlet and the top and is also directed in the first direction. A diverter valve at the inlet is moveable between on and off positions. The on position directs water flowing into the inlet from the inlet, up to the top in a second direction opposite the first direction, and then down to the outlet in the first direction. A turbine at the top has a turbine shaft that extends outside the tool. An abrasive member is connected to the turbine shaft and is configured to rotate when water flows from the inlet to the outlet.

摘要： A method of controlling a vehicle display apparatus may include generating a user image as information on a user sitting on a seat corresponding to the display apparatus, extracting a midpoint between two eyes of the user from the user image and monitoring a position of the midpoint, and changing an output mode or an output area of the display apparatus in correspondence with the monitored position of the midpoint.

摘要： An infrared polarizing filter is attached to an infrared synchronization signal radiator of a stereoscopic image display device which alternately displays right and left images by time-division with polarized light in one direction to radiate the polarized-light infrared synchronization signal. The problem with the occurrence of crosstalk is solved. Stereoscopic image appreciation eyeglasses have polarizing plates, visual field opening/closing liquid crystal cells and tilt correcting liquid crystal cells. The synchronization signal is received by a receiver mounted on an eyeglass frame. The tilt correcting liquid crystal cells are adjusted based on the eyeglass frame tilt angle detected.

摘要： Embodiments allow different viewers of a shared display to see different images. Images may have different combinations of polarization and time slices that correspond to filters in glasses worn by the viewers. The images viewed by each of the glasses may be based on the tracked position and orientation of the glasses, so that the images correspond to the user's viewpoint. Different images may be presented to left and right eyes for 3D stereoscopic viewing. The lenses of the glasses may have a filter that selects light of a specific polarization combined with a shutter that passes images during a specific time slice. The polarization filter may select circularly polarized images of a desired orientation and emit linearly polarized images. The shutter may use liquid crystals to twist the linearly polarized images during the desired time slice so that a final linear polarizer passes the image to the viewer.

摘要： A stereoscopic display method or system includes an image display panel, object tracking sensors, and a means to create first or left, and second or right stereoscopic images based upon viewpoint location. This allows the user to perceive the viewed 3D stereoscopic image as approximately fixed in space. A first embodiment employs differently filtered colored, stereoscopic images. The first and second differently filtered colored images may be perceived as a 3D stereoscopic image by applying anaglyph glasses. In a second embodiment the method of passively polarized glasses may be applied with the result being a stereoscopic image whose location is approximately fixed in space. A third embodiment employs passively polarized anaglyph glasses. This provides the advantage of allowing two different viewers to see different virtual 3D stereoscopic images whose location remains approximately fixed in space. By employing tracking sensors, user gesturing or pointing may now allow interaction with the virtual 3D stereoscopic images in much the same way 2D objects are manipulated by employing a touch screen. This may be combined with voice commands. This allows for input systems such as virtual 3D touch panels, keyboards and remote controllers. In addition virtual 3D objects may be pushed, pulled rotated or manipulated in almost any way a real 3D object would be. The methods described may be applied in other ways, including, but not limited to gaming systems, 3D virtual caves, and simulators. It may also be used wired or wirelessly to remotely control or interact with other devices.

摘要： A control method and a control apparatus for a naked eye 3D display apparatus and a naked eye 3D display apparatus are described. The control method for a naked eye 3D display apparatus includes: detecting the position of a user; determining viewpoints where the left eye and right eye of the user are located according to the detected position of the user; and turning on sub-pixels corresponding to the determined viewpoints and turning off other sub-pixels. Such a control method enables a user is caused to only see those display pictures corresponding to viewpoints that need to be seen, thereby solving the problem of cross-talk between multiple viewpoints.
