Abstract: A display includes a backlight source, display panel, first light source, and controller. The display panel includes a sensor array for sensing first reflection light generated from an object reflecting first detection light. The first detection light is generated by the backlight source for locating a coordinate of a projection point of the object on the display panel. The first light source is disposed in a first side of the display panel, for repeatedly transmitting second detection light of different transmitting angles to the object at different time to generate a second reflection light. The second reflection light is sensed by the sensor array. The controller is for performing a corresponding operation according to a transmitting angle of the first light source and the coordinate of the projection point when brightness value of the reflective light is substantially greater than a predict value.

Abstract: A method utilized in a three-dimensional pointing system is provided according to the present invention. The three-dimensional pointing system includes a pointing device, a sensor array, and a display panel, wherein the sensor array is embedded within the display panel. The pointing device projects a pointer onto the display panel to form a projection image, and the sensor array accordingly generates a sensed image which includes the projection image. The method determines at least one space status information based on the sensed image.

Abstract: An interactive stereo display system and a method for calculating a three-dimensional (3D) coordinate are provided. The interactive stereo display system includes a plurality of interactive devices, a stereo display panel, and a processing unit. When the stereo display panel is irradiated by a light radiated from a light source of each interactive device, an image of each light filtered by a color filter is captured by an in-cell type optical sensor array. After receiving the images, the processing unit determines overlapping circle objects in each image and identifies the circle object formed by each light source according to a light intensity value at the center of each circle objects. Accordingly, the 3D coordinate of each interactive device relative to the stereo display panel can be calculated according to the center and a radius of each circle object corresponding to each light source.
