Abstract: A photo element includes a capacitor, a switch thin film transistor (TFT), a charge thin film transistor, and a photo thin film transistor. A voltage is charged to the capacitor through the charge TFT, and the output voltage of the capacitor is read through the readout line. The photo-induced current will affect the output voltage of the capacitor; therefore it is employed to determine whether the photo element is touched. Later, a reverse-biased voltage is applied to the photo TFT, such that the threshold voltage and sensitivity of the photo TFT can be maintained.

Abstract: A transflective liquid crystal display (TR LCD) including a display panel, a first reference voltage line and a second reference voltage line is disclosed. The display panel includes: a plurality of scan lines; a plurality of data lines, disposed substantially perpendicularly to the scan lines; a plurality of pixels arranged in an array, respectively coupled to a corresponding data line and a corresponding scan line. Each pixel has a transparent area and a reflection area, and each row of pixels is divided by definition into a first pixel-group and a second pixel-group. The above-mentioned first reference voltage line and second reference voltage line are respectively coupled to the reflection areas of the pixels of the first pixel-group and the second pixel-group of each row of pixels for respectively receiving a first reference voltage signal and a second reference voltage signal, wherein both the reference voltage signals are time-varying or periodic.

Abstract: An embedded type inductive input display device capable of increasing aperture ratios, that is realized through parallel-connecting at least two sensing devices of adjacent pixels separated by a gate line, and said sensing devices are connected to a switch transistor, such that said switch transistor is under control of said gate line, and sensor signals output by said sensing devices are transmitted to a read line for detecting touch-control events and positions. As such, the size of said sensing device utilized can be reduced, hereby effectively increasing aperture ratio of a panel, while maintaining a same magnitude of said sensor signals.

Abstract: A three-dimensional image display device and a displaying method thereof. The display device includes a pixel array, a sub-pixel rendering device and a mask. The sub-pixel rendering device provides data signals to the sub-pixels to form the first frames and the second frames. The first frame and the second frame include a plurality of first pixel regions and a plurality of second pixel regions. The second pixel region and the adjacent first pixel regions have some sub-pixels in common. The mask projects the first frames and the second frames as a first image and a second image.

Abstract: A surface profile measuring method using a broad bandwidth light source illuminating a sample surface and a reference surface through a splitter is provided. By changing a distance between the sample surface and the reference surface with a constant step, an interference diagram with a waveform composed of interference data points depicting a relationship of surface height versus illumination intensity is generated. In the beginning, a first data point with greatest illumination intensity is selected from the interference data points on the waveform. Then, a second data point is selected from the data points on the waveform within a predetermined range centered at the first data point to have the waveform showing best quality of symmetry. Then, a peak of a fringe defined by the second data point and its neighboring data points is estimated by using phase compensating approach.

Abstract: A repairing method for a surface profile is provided. The intensity on the waveform of the interference diagrams or the existence of envelope on the waveform of the interference diagram are used to decide whether the respected pixel is located in a dark area on the surface profile or not. Then, mark the pixel located in the dark area. Afterward, repair the marked pixel by using the surrounding effective pixels on the surface profile.
