New Description: [New Technology Field] [0001] This creation is about a touch structure, especially a touch system for a display. [Prior Art] [0002] In recent years, flat panel displays have gradually become the mainstream of home televisions and computer screens because the manufacturing cost of flat panel displays has been drastically reduced. In addition, because flat-panel displays are lighter and thinner than TVs that traditionally use cathode ray tubes (CRTs), they can be used in public places such as train stations, hospitals, convenience stores, or movie theaters. ,. * * .,,,: In order to find more and more flat display, the flat display can be used not only for the display of messages, but also for the purpose of wide-ranging, the application of f: f can be said to be More and more extensive. [0003] As people's functional requirements for electronic devices or flat-panel displays become more diverse, their related technology research and development: manufacturing technology is also changing with each passing day. For example, the need for a touch screen allows people to easily operate a computer, cell phone, squeak, swimming pool or other electronic device; with its screen display and screen press control, people can abandon complex keyboards Key operation, through the clearly marked pattern on the screen and the user-friendly interface to achieve the purpose of display and touch operation. [0004] At present, large-size touch screens (generally larger than 10.1 inches) are most common in both resistive and capacitive modes. Both resistive and capacitive touch screens achieve the purpose of detecting finger position by changing the electrical characteristics of the surface of the screen. However, when the above two touch methods are used to form a large number multi-touch of the M399375 form number Α0101 3rd page, the cost will increase as the size of the touch screen increases; and On the surface of the camp, a layer-to-layer circuit is used to detect the electrical characteristics, which reduces the brightness of the screen. The capacitive type needs to be in direct contact with the finger, and has the problem that it cannot be used through the glove. Therefore, there are still some inconveniences. [0005] Therefore, how to reduce the manufacturing cost of the touch screen without damaging the brightness of the screen is an objective of those skilled in the art. [New Content] [0006] The main purpose of this creation is to reduce the manufacturing cost of the touch screen. This creation is also aimed at making the touch firefly|_„_NEW, allowing the user to use the glove or the continuation of the finger to touch the screen. In order to achieve the above purpose, the present invention provides a display touch system' The display system includes a screen, at least two light source modules, at least one optical sensor, and at least one image processing module.

V** ·-;·.·· - The display touch system as described above is off: ΐ where the number of sensors per sensor is two Or four, and the plurality of optical sensors are not disposed on the same line. Thus, the display touch system of the present invention can achieve the function of touch control of any computer, mobile phone, stereo, refrigerator or electronic device without using Responsible capacitance And the resistive touch system 6 also has a practical commercial value because the touch control system of the display adopts a non-contact measurement method, so that the brightness of the screen is not reduced.

The control system 1 includes a camping screen 5, two light source modules 13 and an optical sensor 11. The screen 丨 5 can be used to display an image video screen. The light source modules 13 are all long-axis type structures, and can emit light in a vertical direction. The two light source modules 13 are respectively disposed on the upper side and the left side of the screen 15 and are perpendicular to each other; Therefore, the upper side of the light source module 13 has a long axis which is disposed in the left-right direction, and the light is vertically perpendicular to the long axis and is emitted downward; the left side of the light source module 13 has a long axis in the up and down direction. Set 'and its light is perpendicular to the long axis and shoots to the right. Therefore, the light emitted by the light source module 13 on the upper side is perpendicular to the light emitted from the light source module 13 on the left side. The plurality of light beams emitted by each of the light source modules 13 form a light projection surface (as indicated by the dotted line, the poor light piano is set to ^3, and the display is on the screen 15). Side and left side ^: You can use the light source mode of the Nana side, and the light projection surface of the group 1 3 from the top to the bottom. The light source module 13 on the left side has a light projection surface from the left to the left. The right projection; moreover, the plurality of rays emitted by the light source module 13 on the upper side and the left side are parallel to the screen ; 5; that is, the light projection surfaces are parallel to the screen 15.
