Abstract: The present invention discloses a thermal pile sensing structure integrated with one or more capacitors, which includes: a substrate, an infrared sensing unit and a partition structure. The infrared sensing unit includes a first and a second sensing structure. A hot junction is formed between the first and the second sensing structures at a location where the first and the second sensing structures are close to each other. A cold junction is formed between the partition structure and the first sensing structure at a location where these two structures are close to each other. Another cold junction is formed between the partition structure and the second sensing structure at a location where these two structures are close to each other. A temperature difference between the hot junction and the cold junction generates a voltage difference signal. Apart of the partition structure forms at least one capacitor.

Abstract: A noise-cancelled capacitive touch display apparatus includes a display panel and a capacitive touch sensor on or above the display panel. The capacitive touch sensor includes plural sensing lines, plural driving lines, plural first signal lines, plural second signal lines and a noise cancellation line. The sensing lines are parallel with each other and extend along a first direction. The driving lines are parallel with each other and extend along a second direction, wherein the second direction intersects the first direction. Each first signal line is located outside of an outermost driving line. Each second signal line is located outside of an outermost sensing line. The noise cancellation line is a cut-off part of a corresponding first signal line or a corresponding second signal line. The noise cancellation line receives the noise generated from the display panel.

Abstract: An optical touch apparatus includes a first light source, a second light source, a light guide device, a light reflecting device and an image sensing module. The first light source emits first light beam which travels within the light guide device and is reflective by an object close to or in contact with a surface of the light guide device to become a first image light beam. The first image light beam is reflected by a light reflecting device. The image sensing module receives the first image light beam. The second light source emits a second light beam, wherein when the optical touch apparatus moves on a working surface, the second light beam is reflective by the working surface to form a second image light beam which is received by the same image sensing module.
