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.

Abstract: A position tuning structure is disclosed, which comprises a holding tube having a side hole extending through the wall of the holding tube; a nut locating in the holding tube and connecting to the side hole; a tuning element threadedly engaged in the nut; an elastic rod locating in the holding tube and pushed by the tuning element; a supporting element locating in the holding tube and pushed by the elastic rod; and an elastic element locating in the holding tube and connecting to the supporting element. Also, an adjustable optical film device comprising the above position tuning structure is disclosed.

Abstract: An image-processing method adjusts the gamma characteristic of an LCD device based on the difference between color coordinates of an image when viewed directly in front of the LCD device and at an angle. Therefore, color characteristics of the image are substantially the same when viewed directly in front of the LCD device and at an angle.
