Abstract: Examples of nibs for styluses are described. In an example, the nib is made of a base material (for example, a polyamide or a polycarbonate), a conductive material (for example, carbon fiber), and a grey color controlling material (for example, a white powder). The base material is in a range of 70 weight percentage (wt %) to 75 wt %. The conductive material is in a range of 15 wt % to 20 wt %. The grey color controlling material in a range of 5 wt % to 10 wt %.

Abstract: An apparatus can include a calibration circuit to determine a backlight status of a display device based on a detected difference in a noise level corresponding to the display device. The calibration circuit can perform an operation to calibrate a touchscreen coupleable to the display device based on the determined backlight status.

Abstract: The present invention provides a display apparatus for capturing images. The display apparatus includes a first substrate, a pixel array disposed on the first substrate, a thin film transistor array disposed in the pixel array and a photodetector array disposed in the pixel array. The pixel array includes a plurality of sub-pixels. The thin film transistor array controls image data transferred to the pixel array. When a light illuminates a sub-pixel of the pixel array, a photodetector corresponding to the sub-pixel of the photodetector array generates a leakage current in response to a gray-level of the light.

Abstract: The present invention provides a gesture recognition system and method which utilizes an open gesture and a close gesture made by a user's hand in simulating a releasing operation and a pressing operation of a mouse. In the present invention, the coordinate of the user's hand is unlikely to shift or change when simulating a mouse click. The present invention can solve the problem of the hand coordinate that is shift when simulating the mouse click in convention skills.

Abstract: A touch input device includes a substrate and a plurality of touch-sensing strips. The substrate has a flat surface. The touch-sensing strips are all disposed side by side on the flat surface. Each touch-sensing strip includes a plurality of sensing electrodes electrically connected to one another in series. Each sensing electrode has a top surface, and the areas of the top surfaces in at least two sensing electrodes of each touch-sensing strip are not equal to each other.

Abstract: An electrically-driven liquid crystal lens is disclosed. The electrically-driven liquid crystal lens being partitioned into a lens region and a non-lens region includes: a first and a second substrates disposed opposite to each other; a protrusion formed on the first substrate corresponding to the lens region, a first electrode formed on the first substrate and the protrusion for guiding electrical fields to increase the focus of the lens, and a second electrode formed on the non-lens region of the second substrate; a liquid crystal layer provided between the first electrode and the second electrode. A stereoscopic display using the electrically-driven liquid crystal lens is also disclosed.
