  • Publication number: 20160125808
    Abstract: A pixel structure includes a light-emitting diode, a transistor, a data-receiving unit, a compensating unit, and a resetting unit. The transistor is configured to be electrically coupled to the light-emitting diode, and drive the light-emitting diode based on a voltage difference between the control terminal and the first terminal of the transistor. The data-receiving unit is configured to be electrically coupled to the first terminal of the transistor, and provide a pixel date signal to the first terminal of the transistor based on a first scan signal. The compensating unit is electrically coupled to the control terminal and the second terminal of the transistor to act as a current path therebetween. The resetting unit is electrically coupled to the light-emitting diode. The resetting unit is configured to respectively provide a reverse bias and reference voltage to the light-emitting diode and the control terminal of the transistor.

  • Patent number: 9318047
    Abstract: An organic light emitting display unit structure including a first pixel, a second pixel adjacent to the first pixel, a first scan line electrically connected to the first pixel, a second scan line electrically connected to the second pixel, a data line, a power line, a sustaining signal line, a common reset signal line and a common light emitting signal line is provided. The power line and the sustaining signal line are respectively electrically connected to both of the first pixel and the second pixel. The data line intersects with the first scan line and the second scan line and is electrically connected to the first pixel and the second pixel. The common reset signal line and the common light emitting signal line are substantially disposed inside the first pixel and the second pixel respectively and are electrically connected to the first pixel and the second pixel.

  • Patent number: 8754847
    Abstract: An interactive three-dimensional display system includes a three-dimensional display panel which has an optical sensor array, an interactive device which includes a projection light source and a shadow mask, and an image recognizing unit. The shadow mask has a pattern to define an image projected by the interactive device. The image is captured by the optical sensor array. The pattern includes two strip patterns which cross each other. The image includes two strip images which cross each other. The image recognizing unit is electrically connected with the optical sensor array and calculates relative positions of the interactive device and the three-dimensional display panel according to the image. A method of calculating the relative positions includes calculating according to the lengths of one of the strip patterns and one of the strip images, and a divergent angle and tilt angle of the projection light source.

  • Patent number: 8531458
    Abstract: An exemplary method of determining a pointing object position for three-dimensional interactive system, adapted for an interaction between a pointing object and a three-dimensional interaction display with embedded optical sensors. The method includes the steps of: acquiring a two-dimensional detected light intensity distribution caused by the pointing object acting on the three-dimensional interaction display; obtaining two light-shading intensity maximum values according to the two-dimensional detected light intensity distribution; and determining a one-dimensional positional information of the pointing object on a distance direction of the pointing object relative to the three-dimensional interaction display by use of the positional distance between the two light-shading intensity maximum values.
