A display device (100) includes: a display panel (1) capable of being in a transparent display state where a background scene is viewable through the display panel; a panel light source (3) that irradiates the display panel with colored light of a plurality of colors in a time division manner; a rear side light source (2) placed on a rear surface side of the display panel, the rear side light source being capable of emitting colored light of a plurality of colors in a time division manner; and a control circuit that controls emission timings of the colored light from the panel light source and from the rear side light source, wherein the panel light source and the rear side light source are synchronized by the control circuit such that colored light of different colors are not emitted at a same timing.

According to one embodiment, a driving method of a display device including a display area in which liquid crystal pixels are arranged in a matrix, a plurality of scanning lines arranged along display rows, a plurality of signal lines arranged along display columns, a backlight which illuminates the display area, and a controller which controls a display operation, the driving method includes via the controller, driving the scanning lines alternately from a center of the display area to both edges of the display area, outputting video data corresponding to a driven scanning line to the signal lines in synchronization with the driving of the scanning line, and turning on the backlight for a predetermined time after outputting the video data of one frame.

The invention relates to an articulated arm coordinate measurement machine for a measurement of geometrical features of an object, comprising a stationed end of the articulated arm, opposed to a movable end of the articulated arm being manually movable by a human operator. A measurement probe head is attachable to the movable end. It also comprises a graphical display unit located at the movable end of the articulated arm, in particular in vicinity of the probe head, in such a way that information provided by the display unit is visible for the operator during measurement. The display unit is built to provide an artificial view, which is graphically representing at least part of the object, in particular with respect to a point of view from or nearby the movable end of the arm so that the artificial view is similar to the operator's natural view of the object.

In general, in one aspect, a three dimensional (3D) display includes an optical stack, a backlight, panel electronics and a backlight driver. The optical stack is to present left eye and right eye images. The backlight is to illuminate the optical stack so the left eye and right eye images are visible and to provide signals for synchronizing the image illuminated on the optical stack with shutter glasses worn by a user to enable a left eye to view the left eye images and a right eye to view the right eye images. The panel electronics are to generate the left eye and right eye images on the optical stack. The backlight driver is to control operation of the backlight.

Some embodiments provide a device that employs novel processes for displaying data regarding its movement in a region. For instance, in some embodiments, the device captures and stores location data at a plurality of locations traversed along the route. Upon receiving a request to view the traversed locations along the route, the device displays a representation of at least a subset of locations along the route based on the stored location data. Upon receiving an identification of a particular location in the displayed representation of the subset of locations, the device displays information regarding the particular location.

The present disclosure provides a display apparatus and a display system. The display apparatus comprises a transparent display layer, a light source layer and a signal controller. The transparent display layer is arranged on a surface of a light exit side of the light source layer; and the signal controller is configured to control operation states of the transparent display layer and the light source layer to realize switching between different modes.

A method for writing to an electronic imaging substrate includes passing an electronic imaging substrate in relation to a writing device to change a state of image cells within the electronic imaging substrate. The imaging substrate is placed close enough to the writing device to reduce a blooming effect to a predefined threshold level when changing a state of one of the image cells within the electronic imaging substrate.

Visual training aids including an eyewear article including a lens, an image generator mounted to the eyewear article in a position to display an image on the lens, a processor operatively connected to and in data communication with the image generator, a global positioning system operatively connected to and in data communication with the processor, a computer readable medium operatively connected to and in data communication with the processor. In some examples, the visual training aid includes a pair of eyeglasses. In some examples, the visual training aid includes a display monitor mounted to the eyewear. In some examples, the visual training aid includes a camera mounted to the eyewear.

A display system and a method for displaying items and/or performances is provided. At least a display panel is used to play multimedia content. In an embodiment, at least a portion of the display panel turns transparent for displaying items or performances in a display space. In an embodiment, the display item is moved in accordance with the multimedia played on the display panel. In an embodiment, light effects are adjusted during the display. In an embodiment, audio media is played and adjusted during the display.

An LED panel includes a plurality of LED pixel units being arranged. Each of the plurality of LED pixel units includes: a normal element including a red LED element, a green LED element, and a blue LED element; and a low-luminance element configured to provide an output having luminance lower than the lowest luminance of the normal element.
