Problems solved by technology

[0002] The existing touch screen is not easy to install, so most of the equipment that needs to be installed with a touch screen has already installed the touch screen on the equipment when it leaves the factory
As a result, end customers have no choice as to whether there is a touch screen on the device
[0003] Some equipment is equipped with a touch screen in advance, but the customer does not need it. This situation is a waste for both the customer and the manufacturer.
Some equipment is not equipped with a touch screen in advance, but the customer needs to use a touch screen. In this case, the customer may choose other products, or need to spend a high cost to modify the equipment. This situation is also unfavorable to customers and manufacturers. Producers may lose customers as a result, customers may spend more

specific Embodiment 1

[0045] refer to image 3 The touch position detection module 3 may be a touch position detection module that adopts the structural principle of the click position detection module for determining the click position, which is adopted by the existing virtual laser keyboard. It includes an infrared emitting source 310 and an infrared signal receiving module 311 . An infrared image positioning device is arranged inside, and the infrared signal receiving module 311 is connected to the infrared image positioning device. In order to eliminate the signal blind area at a short distance, the optical signal receiving part of the infrared signal receiving module 311 is relatively protruding and inclined downward.

[0046] The click position detection module adopted in the existing virtual laser keyboard can better detect the click position and accurately locate it. It can be directly applied to the present invention to detect and locate the touch point. The click position of the virtua...

specific Embodiment 2

[0052] The touch position detection module 3 can also determine the touch point by adopting the technical solution described in the patent titled "Laser Remote Control Signal Receiver and Its Supporting Laser Remote Control Signal Transmitter" and the application number is 200810035508.x The position of the touch position detection module 3. This needs to be used in conjunction with a dedicated touch pen that can emit light beams. Take the light point presented by the light beam on the display screen 6 as the touch point.

[0053] refer to Figure 5 , Figure 6 The touch position detection module 3 includes a photosensitive element group, and the photosensitive element group includes at least two photosensitive elements, and the photosensitive element group is covered with an optical signal directional receiving device 321 for filtering non-correlated direction optical signals. The photosensitive element 321 is connected to a signal processing module 322 for processing elec...

specific Embodiment 3

[0059] refer to Figure 8 , the touch position detection module 3 includes a camera 33 for capturing images on the display screen 6 . The camera device 33 is connected to the microprocessor module 1 and transmits the touch point image to the microprocessor module 1 . The microprocessor module 1 is a microprocessor module 1 capable of determining the position of the touch point through the image of the touch point. Existing image interaction technologies can already fulfill the above technical requirements well, so no more details are given here.

[0060] It can be applied to mobile phones, handheld computers, desktop computers, projector systems and other equipment. Especially for the projector system, it can realize the remote control of the host computer at the screen. In order to further reduce or even eliminate blind spots, the above design is particularly easy to install at the corner of the display screen 6 .

technical field [0001] The invention relates to a touch screen, in particular to a touch screen which is convenient to be installed on a controlled device. Background technique [0002] Existing touch screens are not easy to install, so most of the devices that need to be installed with touch screens have already installed the touch screens on the devices when they leave the factory. As a result, end customers have no choice as to whether the device has a touch screen or not. [0003] Some equipment is equipped with a touch screen in advance, but the customer does not need it. This situation is a waste for both the customer and the manufacturer. Some equipment is not equipped with a touch screen in advance, but the customer needs to use a touch screen. In this case, the customer may choose other products, or need to spend a high cost to modify the equipment. This situation is also unfavorable to customers and manufacturers. Producers may lose customers as a result, and cus...
