Please refer to Fig. 4 B, it is the schematic diagram of the another kind of display device 10 according to the utility model first embodiment.In figure 4b, identical label represents same or similar aforementioned components, and therefore its detailed mode of operation is not repeating in this.Display device 10 includes optical sensing module 200, control module 130, switch 140 and an indicating member 250.Indicating member 250 signal is coupled to control circuit 130, is used for pointing out user at least one function input.Indicating member 250 can be the wherein at least one of a liquid crystal panel (LiquidCrystalModule, LCM), loudspeaker, a pilot lamp and a shaking device.On the other hand, optical sensing module 200 includes computing module 200, image sensing module 210, bus 230 and a communication module 235.Communication module 235 signal is coupled to computing module 220, is used for carrying out thorough cut with control circuit 130.Communication module 235 and control circuit 130 link up can be wired (such as: USB interface, SPI interface, UART interface, I2C bus etc., and be not limited thereto) or wireless (such as: bluetooth, radio area network, infrared ray, radiowave etc., being not limited thereto).

In order to describe the mode defining touch area with image sensing module 210 in detail, please then with reference to Fig. 5.Fig. 5 is the schematic appearance of the image sensing module according to the utility model one embodiment.Image sensing module 310 includes image sensor 330 and 340.Wherein, image sensor 330 and 340 provides a specific sensing range to sense the object being positioned at sensing range respectively, and image sensor 330 and 340 can be CMOS image sensor (CMOSImageSensor, CIS), or general photosensitive coupling element (ChargeCoupledDeviceSensor, CCDSensor).As shown in Figure 5, the sensing range of image sensor 330 is the regions between dotted line 332 and dotted line 334, and the sensing range of image sensor 340 is then the region between dotted line 342 and dotted line 344.The touch area 360 that overlapping i.e. this image sensing modules 310 of two sensing ranges defines, as the scope controlling 380, pattern and should be positioned at touch area 360 and cover.Once there be object to enter into touch area 360, image sensor 330 will obtain the image feature corresponding with detected object respectively with 340 from the presentation content sensed, and these image features is sent to computing module (as shown in Fig. 4 A or 4B).Computing module will calculate the position of object according to received image feature, and position is sent to control circuit (as shown in Figure 1) and is able to operate accordingly and accordingly to make control circuit.In the utility model embodiment, angle is set should be set as reaching touch area 360 maximum magnitude of image sensor 330 and 340, but be not limited thereto.
