The 'photoreceiver 丨3 is an image sensor provided with a charge coupled sensing element (CCD) or a CMOS sensing element, which is disposed on the reflection path of the infrared signal to receive an infrared signal, and according to the The infrared signal corresponds to the contact point position signal of the light emitter U on the liquid crystal display 1 (), and then through a wired, for example, _ line or wireless transmission interface, such as a Bluetooth transmission interface, a wireless USB transmission interface or infrared transmission. Surface, the contact point position signal is transmitted to the host laptop Shu Shu 4. A host positioning processor (not shown) is built in the host computer 14, which can convert the contact point position signal into a coordinate position on the liquid crystal display 1G according to the coordinate position record on the liquid crystal display 1Q during the previous correction, and borrow The number of times the touch light emitter U touches on the liquid crystal display 1G, the time of money: the moving direction, etc., determines the actuation command issued by the user, and executes the actuation command 'to display the actuation result on the liquid crystal display stomach 1Q, and It achieves the purpose of being controlled by the optical signal input and interactive display with the user. Since the coordinate display processor generates the corresponding display content or action according to the touch signal, which is a conventional technique, and is not the focus of the present case, it will not be described here. In addition, in order to prevent the infrared signal reflected by the liquid crystal display 1G from being shielded by the user and the unloaded light receiver 13 is smoothly received, the embodiment may further add one or more light receivers at different positions or angles. The reflected signal is received, and the host 14 selects a signal with a strong signal strength from the signal 20121822 transmitted from each optical receiver 13 for subsequent processing. Referring to FIG. 7 and FIG. 8, a second preferred embodiment of the optical input and control system of the present invention is different from the first embodiment. The optical receiver of the present embodiment directly utilizes the inside of the notebook computer 1. A webcam 15 is built to receive the infrared signal reflected by the liquid crystal display 1 , and the embodiment further includes a light reflecting component 16 ′ disposed above the network camera 15 , which is a mirror that can be used by the liquid crystal The reflected infrared signal of the display 1 is reflected toward the network camera 15, so that the network camera 15 can "see" the entire liquid crystal display 10 screen to receive the infrared signal. Referring to Figure 9, the optical input and control system of the present invention is shown. In a third preferred embodiment, the optical input and control system of the present embodiment is exemplified by a digital television 2 having a non-projection display (liquid crystal display) 2, and the light reflecting unit 12 is the same as the first embodiment. The surface of the liquid crystal screen is disposed on the surface of the liquid crystal screen to reflect the light signal projected onto the surface of the liquid crystal screen 20 to the light receiver. Unlike the first embodiment, this embodiment uses non- In the touch-type (remote-controlled) optical input and control mode, the light emitter 21 is a non-contact light emitter, and includes a grip portion (for example, an elongated rod body) 211 and a tip end portion of the grip portion 211. a light-emitting element 213<5 for emitting a laser light signal in a light-transmissive housing (light-transmitting lamp cover) 212. In this embodiment, the light-emitting element 213 is a laser capable of emitting an infrared laser light signal. Due to the collimation (low divergence) and high intensity of the laser, the light emitter 21 can directly reflect the laser beam projected onto the surface of the liquid crystal screen without directly contacting the surface of the liquid crystal screen 2G. The infrared laser light signal of sufficient intensity is received by the light receiver 13. 10 201218022 The wavelength of the infrared laser light signal emitted by the right light emitting element 213 is invisible light, in order to allow the user to see the laser light hitting the liquid crystal screen 2 The position is to input or control the digital television 2. In the operation mode, the light emitter 21 continuously emits infrared light signals to the surface of the liquid crystal screen 2, so that the reflected infrared signals are lighted. The receiver 13 continuously receives to generate a contact point position signal, and transmits the contact point position signal to a coordinate positioning processor (not shown) in the host 14 to convert the contact point position signal into a display state. The coordinate position is displayed on the liquid crystal screen by a cursor, so that the position of the cursor corresponds to the position of the contact point of the infrared light beam projected on the liquid crystal screen, whereby the functions corresponding to various optical signal changes can be preset in the host computer 14, The user can control the light emitter 21 to emit a pulse beam of different frequencies to achieve the function of the remote control, for example, when the user presses a first button 214 on the grip portion 211 of the light emitter 21 to control the light emitting element 213 to emit The 100 Hz pulse beam indicates that a function equivalent to the left click of the mouse is performed, and a second button 215 on the grip portion 211 is pressed to control the light-emitting element 213 to emit a 200 Hz pulse beam, indicating that the execution is equivalent to sliding. Clicking on the function, if a third button 2 on the grip portion 211 is pressed, the 7L member 213 emits a 300 Hz pulse beam, indicating that the equivalent mouse is to be executed. Function 'and if pressed on the grip portion 211 - a fourth button 216 light emitting element 213 emits 500Hz pulse beam, it indicates to perform the equivalent of mouse ",, Left drag function. In addition, in addition to the above, the infrared laser diode 213 4 may be approached on the grip portion 211, and an independent visible laser light source (not shown) is continuously disposed to project the visible laser light onto the liquid crystal screen 2 The user, 201218022, can grasp the position where the infrared laser beam is projected on the liquid crystal screen 20. In this case, the 'infrared laser diode 213 does not need to continuously emit infrared laser light signal' only needs to be remote input by the user. Or the infrared laser light signal is emitted to the liquid crystal screen 2 遥控, and the infrared laser light signal is reflected to the light receiver 13 by the light reflecting unit 12 on the liquid crystal screen 20, and a corresponding one is generated by the light receiver 13. The position signal is given to the host 4 to achieve the purpose of remote input or remote control. Therefore, 'a mouse-like click function is achieved by presetting various actions corresponding to various optical signal changes on the host'. For example, the user presses the first button 214 on the grip portion 211 of the light emitter 21 to control the infrared laser. The diode 213 is switched once, indicating that the "left click" function of the mouse is executed, and the second button 215 on the grip portion 211 of the light emitter 21 is pressed to control the infrared laser diode 213 to be continuously switched twice, indicating that the slide is performed. The mouse "double-click double-click" function, press the third button 216 on the grip portion 211 of the light emitter 21 to control the infrared laser diode 213 to be turned on for a period of time, then switch it again, indicating that the mouse "right click" function is executed. Pressing the fourth button 217 on the grip portion 211 of the light emitter 21 controls the infrared laser diode 213 to be continuously turned on for a period of time, indicating that the mouse "drag" function or the like is performed. In addition to the above, there may be only one button on the grip portion 211, and the user can operate by clicking the number of times or the speed of the button, and by controlling the function corresponding to the change of the transmitter optical signal. , to achieve the purpose of similar mouse left and right input. In addition to the above-mentioned change of the pulse beam frequency, the change of the transmitter light intensity and the wavelength of the light can also achieve the purpose of corresponding function actuation. 12 201218022 In addition, the light-emitting element 213 of the present embodiment can also achieve the above-mentioned purpose of the digital signal remote control digital television by using the high-directed infrared light-emitting body.
