Description

99· 12. Year of the month, the new description: [New technology field] 1曰7 Wenben creation provides an optical touch module structure, especially a kind of photosensitive device installed in the outer frame of the video device into a special The beveled design makes the illumination light unable to reflect, ensuring that the touch medium is always a bright point optical touch module. [Prior Art] In the history of electronic devices, keyboards, mice, and touchpads appeared to solve input control problems. However, for beginners, it is quite important to learn to use these input interfaces, and the space is not small. For example, half of the volume of a notebook or mobile phone is occupied by the keyboard. If you can save keyboard space, you can naturally improve the portability of the product. The most feasible way is to operate the touch panel directly on the panel. Therefore, there is an increasing demand for the application of Pointing Stick and T〇uch pad technology, and it is expected to replace the operation functions of the traditional mouse and keyboard 'because of the gesture language_ No (four) misunderstanding, - some academic research institutions began to develop the technology of the gesture language, making the touch panel operation more user-friendly and will allow multiple fingers, palms and new users to simultaneously use the highest level of '_hand touch . Difficult to develop technology, in fact, it has been a year of 'but' since the iPhone launched, for the touch market has cast i shock bombs, the electronics industry learned that 'touch screen is not just a niche market, in fact enough to become a host input; . The iPhone proves that a good touch interface can really replace most keyboard functions' and give users a more intuitive and convenient operation experience; with a larger 99.12. M410285 plus a fully-incorporated panel replacement keyboard, it can also be designed Thinner and more stylish; 'Solid panel technology, no need to worry about mechanical parts failure such as keyboard, pulley...etc. • IT products will enter the new era of multi-touch. Although you can use a resistor/capacitor to build a multi-touch screen computer, the number of touch points in this way cannot be reported more. Multiple users use it at the same time. The more novel technology is built using a charge-coupled component (CCD) to capture computer vision. In addition to the number of touch points, it is not limited to a single user, so many hands can be used. Other pen-based methods and multi-bit users use it at the same time to reach the highest level of Mutli Touch, and its application space will be unlimited. At present, in the computer operating system, the compatible mode of touch has been developed, so all the industry players are competing for the development of gesture recognition, and want to define different operation gestures. The use of touch screens is increasing, and the development of various technologies is also quite fast. iPh〇ne switched to the projected capacitive technology to achieve multi-touch control, and everyone turned their attention to the new touch technology. Inspiring the touch screen To compete fiercely with multi-touch interactive technology, a variety of different technologies are being developed, such as neocapacitor, surface acoustic and optoelectronic. Due to the increasing speed of image sensing components and image processing in recent years, the image photoelectric touch interactive screen has been emphasized, and many manufacturers have proposed new experimental systems or products. The products that have been witnessed and the C〇mpUting surface published by Microsoft. Both of them use the infrared light to illuminate the finger or contact with the county _, and then use the IR Camera to capture the image for simultaneous multi-touch interaction. The first picture shows the technical principle of Perspective Pixd. The technology adopts the principle of Frustrated Total Internal Reflection (FTIR). The light-emitting diode (LED) is 0 on the side contact plate 90 (the picture shows acrylic). In the material), the total reflection 80 is performed. When the refractive index is higher than the contact of the finger of the contact plate 2, the contact area destroys the internal total reflection 80, and the contact light is irradiated into the finger contact to generate the scattered light 7〇, and the infrared image camera located below 5〇 (Video Camera) Take all the contact point images on the touch panel and calculate the dynamic contact position to interact with the projected content. The technique disclosed in the US 7,411,575 patent application is a sensing mode of 2D touch, a plurality of pointing contacts or moving on a touch surface, the touch surface being detected and generating and transmitting commands to enhance sensing Functional application of the system. The listing of the Windows 7 system, which can handle touch display, will be more eagerly demanded. The existing display device is based on the camera to display the screen border (four) image, and calculate the image in two ways. The position of the finger 'so it is necessary to have the result of the calculation 攸 _ display the screen border I light evenly illuminated. In the early days of the operation of the electronic whiteboard, the LED light source was arranged on the frame, and the uniformity of the frame light source was added by adding a Diffuser (but this mode should be controlled to have a brightness of _ degree); In addition, the structure of the ^ structure is added to the display of the firefly (10) frame, the light source of the rider is illusory to "', the member is not on the line, the t finger enters the person to check _ _ _ _ _ _ _ _ _ _ _ _ _ _ _ _ The location, but this mode of operation must have a certain rate of accuracy in the 3 environment, if it is in the background too dark, the ten is pure and not bright and has distortion; if you want to change the new type, the loss of the month is reduced. Filled with i-shaped, the hard-mounted head on the frame is LED illumination, which will cause the hand j to become a bright spot when it is close to the light source, away from the light _ and become a dark-closed situation, so that there will be a switch interface when calculating Discontinuous appearance. It can be seen that the gesture of the TFf screen is the place where the fine control secrets are struggling. The reflection source of the success or failure of the TFf is also quite worthy. Sewing here, the creator of the case is concerned with the above defects and deficiencies. Study carefully, and with the use of academics, ~ And the creative design of the defect.
