Abstract: The present disclosure generally relates to a new computer input and tracking device, and method of using, more particularly, a new type of digital pen which tracks user hand movements to generate series of point coordinates that represent a drawing or hand writing. Unlike prior digital pens such as the Apple Pencil™ or the Microsoft Surface Pen™, the new system does not require users to write on a touch-sensitive surface. Users can write on any surface such as a notebook, a table, a board, or even in mid air. Users can draw two-dimensional or three-dimensional drawings. The new method utilizes a pen marked with one or more groups of distinct tracking marks or tracking patterns and a camera to track the pen in real-time. A computer running a 3D algorithm processes the camera images, detects and distinguishes the tracking marks, and uses the tracking marks to calculate the positions of the tip of the pen in three-dimensional space.

Abstract: A unit circuit constituting each stage of a shift register serving as a gate driver of a display device charges an internal node to an H level via a transistor T2 when an output signal G(n?4) of a preceding stage turns to the H level and sets the internal node to an L level via a transistor T3 when an output signal G(n+8) of a succeeding stage turns to the H level. Each of the unit circuits of last eight stages in the gate driver is provided with a transistor T4 including a gate terminal to which the signal G(n?4) is applied and a drain terminal connected to the internal node. A signal is applied to a source terminal of the transistor T4, the signal being at the H level during a period when the internal node of any of the last eight stages is to be set to the H level, and being the L level during the other periods. This suppresses a voltage fluctuation generated in the internal node when a stabilization circuit does not normally function.

Abstract: Foldable displays may have portions folded into a folded configuration. Each folded portion may be observed by a user at a different viewing angle. As such, folding-artifacts may appear in the displayed image as a result of the different viewing angles. For example, a perceptible color difference and/or a perceptible brightness difference may appear between folded portions. Disclosed here are systems and methods to create compensated images that when displayed reduced the folding artifacts. The creation may include sensing a viewing angle for each portion and determining adjustments for pixels in each portion using a display model. The display model may be created by measuring color and brightness of pixels for various folded configurations, view-points and/or viewing angles.
