INSTRUCTIONS: TECHNICAL FIELD OF THE INVENTION The present invention relates to an interactive display, particularly to a three-dimensional interactive display and a three-dimensional coordinate detecting method thereof. [Prior Art] With the advent of the digital information life, various digital products have become inseparable from the ordinary life, such as small mobile phones, personal digital assistants and digital cameras, or large-scale shopping malls. Electronic billboards can be seen everywhere; for digital products, the most indispensable is the display function. The early display function is nothing more than displaying the image through the display panel, and gradually has developed into a touch panel that can directly interact with the user; the touch panel is touched by fingers or other substances, according to different side methods. For example, the measurement of voltage, current, sound waves or infrared rays to detect the location of the contact pressure, and the design technology is divided into resistive, capacitive, ultrasonic or optical, etc., the paste control panel is now widely Designed in electronic dictionaries, mobile phones, public information navigation systems and bank ATMs. However, with the image processing technology, the design of the touch panel is moving in a three-dimensional direction. As described in US Patent No. US2006/0012675A1, the user moves and moves in a specific area. The bit tracking system tracks the movements and actions of the viewer and generates three-dimensional position information, and then receives and processes the three-dimensional position information by the image system to generate an image for display on the display. The shift tracking system includes a first image camera and a second image camera for capturing the movement and motion of the user. Since the traditional one-dimensional interactive display captures the movement and motion of the user by the image camera, the coordinate information can be obtained by the analysis of the image. However, most of the image cameras are used. 5 201007520 Using the charge coupled component as the photosensitive element This method will require a larger display hardware volume; in addition, the technology that will be limited by the charge-coupled component will make the user's working range limited to a certain distance. 'When too close and too far distance will make the Detect The measurement sensitivity is reduced. In view of the above, the present invention is directed to the above-mentioned problems, and in combination with the display panel and the photoelectric technology, a three-dimensional interactive display and a three-dimensional coordinate detecting method thereof are proposed. SUMMARY OF THE INVENTION The main object of the present invention is to provide a three-dimensional interactive display and a three-dimensional coordinate detection method thereof, which effectively reduces the volume of the three-dimensional interactive display, and simultaneously increases the three-dimensional interactive display at a close distance. The scope of work. Another object of the present invention is to provide a three-dimensional interactive display and a three-dimensional coordinate detecting method thereof, wherein the grating film can be directly mounted on the completed three-dimensional interactive display, and the manufacturing procedure of the three-dimensional interactive display is not required to be changed. Add extra hardware devices. In order to achieve the above object, the three-dimensional interactive display of the present invention comprises a touch panel and a plurality of lenticular sheets, wherein the touch panel is provided with an array of a plurality of light source sensors, and A carrier frame may also be disposed around the grating strips so that the grating sheets are mounted on the touch panel. After the touch panel is touched by a touch object, the grating piece mounted on the touch panel will cause the touch object to approach the touch panel to cause an asymmetrical distribution of the shadow intensity. Measure n light positions, because the distance between the light (4) and the light source sensor will cause the ray of the wire to be fully slammed, therefore, the light source systems of different heights will be different. The angle light source sensor detects; thereafter, the light source of the H 彳贞 _ is sensed by a processing unit to obtain the three-dimensional coordinates. Therefore, 6 201007520 The present invention is analyzed by the light height _ system, correcting the three-dimensional coordinates to enhance the working range of the three-dimensional interactive display at a short distance. The nails are combined with the specific embodiment to make it easier to understand the purpose and technical content of the present invention. The present invention proposes a three-dimensional interactive limb three-dimensional coordinate detecting method, which is a three-dimensional interactive display in which a direct ampoule is completed, so that it is not necessary to change this. 3D interactive © The hardware device of the three-dimensional interactive display is installed in conjunction with the installation of the grating piece, and the technical features of the present invention will be described in detail in the preferred embodiment. For example, the first figure and the second figure. As shown, the plurality of woven grids 1G are strip-shaped and mounted on a touch panel 14 in a straight alignment. The touch panel 14 has a plurality of light source sensors 16 that are arranged in an array. Arranged in order to detect the intensity of the light source. When a touch object touches the touch panel, the shadow intensity will be generated, and the shadow intensity will be asymmetrically distributed through the grating sheet 1 and then The light source sensor 丨6 detects the intensity of the light source, since the lenticular sheet 1 is located between two adjacent rows of the light source sensor 16, and the lenticular sheet 1 is adjacent to the adjacent light source. The detector 16 partially overlaps 'there is a vertical distance gap between the lenticular sheet 10 and the light source sensor 16, so that the light source sensor 16 of a certain angle will be completely blocked by the lenticular sheet 1 ,, thus 'Light sources of different heights will be illuminated by different angles of light source 16 Detecting; thereafter, the intensity of the light source detected by the light source sensor 16 is calculated by a processing unit (not shown) to obtain a peak value of the light source, and then the peak value of the light source is further calculated by the processing unit. The third figure shows the method of three-dimensional coordinate detection, and refers to the architecture of the first and second figures 201007520 and the exploded view. First, as step S20, the touch panel i4 is touched by the touch object. The touch object is a finger or a stylus. Then, in step S22, the shadow of the touch object is asymmetrically distributed by the touch of the touch panel. The step is like, through the light source _|| 16 ray light degree, the intensity of the light source is divided into horizontal and vertical light source intensity, and the processing unit is the paste value - minus the surface gamma (four) of the horizontal and vertical light source intensity, Silk peak. For example, the fourth ride is shown as a three-dimensional dynamic display. The schematic diagram of the rider's strength is formed by two light source densities forming two light source peaks. The two peaks are separated from each other in the two lateral positions. The height of the blue control panel 14 is proportional to the height; the fifth ride is shown as a vertical light duty of the three-dimensional interactive display, with a light source density forming - a light source peak is present in a longitudinal position. Then, as step gamma, the processing unit adds and divides the positions of the two horizontal light source peaks by two to obtain a first dimensional coordinate; and the processing unit uses the position of the longitudinal light source peak to obtain a second dimensional coordinate The third dimensional coordinate is obtained by calculating the distance between the two horizontal scale values via the processing unit. Finally, as in step S28, a three-dimensional coordinate is obtained. <Descrição] The first embodiment in which a plurality of lenticular sheets 1G are mounted on the touch panel 14 is described. In addition, in order to facilitate the installation and manufacture, the transparent carrier frame U is used as the carrier for carrying the optical blades. As shown in the sixth embodiment, the second embodiment is a strip. The straight alignment pattern is disposed on the transparent carrier frame 12. The grating pieces ω are located between adjacent rows of the light source sensor 16 and adjacent to the light source sensor 16 overlapping. In a second embodiment, as shown in the seventh embodiment, a plurality of lenticular sheets 1 〇 are integrally formed with a transparent carrier frame and a plurality of strip windows 18 are provided for enabling the light source sensor 16 to be 201007520 This strip window 18 is revealed. & It is known from the implementation of the ship to understand the relationship between the read light and the height of the system, and then obtain the two-axis standard 'to enhance the three-dimensional silk display ^ in the close range of work, and do not need to change this two-dimensional In addition to the manufacturing process of the interactive display, there is no need to add this three-dimensional interactive _ (four) hardware to match the grating 1 (). The invention will be beneficial to the photovoltaic industry and the 7FH industry. Further, the shape of the grating sheet 1G of the present invention may be a block shape and may be arranged in a horizontal arrangement and disposed between adjacent columns.

That is, the equivalent changes or modifications made by the spirit of this disclosure are still to be covered by the patent of the present invention.
