Embodiment
Basic thought of the present invention is: camera is installed on the LCD of handheld device, by the ITO on the LCD of handheld device the handheld device mainboard is connected with the camera module of handheld device, because the ITO cabling on the LCD of handheld device is on the LCD of handheld device, can not produce the volume that wiring problem and this ITO cabling do not take the handheld device casing, this ITO cabling more can not be subjected to the interference of handheld device rf signal line or other data lines, therefore, can make the overall volume of handheld device littler and can not have influence on the display effect of handheld device LCDs.
For making the purpose, technical solutions and advantages of the present invention clearer, below be embodiment and with reference to accompanying drawing with the mobile phone in the handheld device, the present invention is described in more detail.
Fig. 1 is present mobile phone cam distribution schematic diagram, as shown in Figure 1, the camera 1 of at present traditional mobile phone generally be positioned at LCD of mobile phone 2 above or below (not shown), but the LCD2 of camera and mobile phone does not have tie point, generally directly be connected by corresponding data line with cell phone mainboard, because casing finite volume, inevitably can be equidistant nearer with audio frequency, the radio frequency line of mobile phone, will have influence on the display effect of camera, the installing of existing camera will take the bigger space of hand set machine shell.
Fig. 2 is a mobile phone cam distribution schematic diagram of the present invention, as shown in Figure 2, camera 1 of the present invention is positioned on the LCD 2, and links to each other with chip for driving 5 or the cell phone mainboard (not shown) of LCD 2 by indium tin oxide (ITO, the Indium Tin Oxide) cabling 4 on the LCD 2.Concrete connected mode will be described in detail hereinafter.
Fig. 3 is the syndeton synoptic diagram of mobile phone cam of the present invention and cell phone mainboard, as shown in Figure 3, mobile phone cam module 1 among the present invention is positioned on the glass substrate of LCD 2, and be fixed on the binding position 6 of camera, utilize conductive material ITO matured photoetching process on the LCD glass substrate, on ITO, etch ITO cabling 4 as shown in Figure 3 in advance, the ITO cabling 4 that etched is coupled together with the bottom solder joint of camera module 1 respectively.Concrete, camera module 1 can adopt the mode of hot pressing to be fixed on the glass substrate of LCD, (ACF, AnisotropicConductive adhesive Film) is bundled in camera module 1 on the binding position 6 of camera by the anisotropic conductive film on the LCD.
Fig. 4 is the solder joint distribution schematic diagram of camera module of the present invention, as shown in Figure 4, traditional solder joint generally be positioned at camera module bottom under, and the camera module generally adopts the mode of hot pressing to be connected with mainboard, like this, be easy to cause the damage of camera module, therefore, the present invention is extended to camera bottom solder joint as binding position 6 parts among Fig. 3 (among the figure shown in the dash area), thereby effectively prevent from pressure and the high temperature that produces in the camera module process is installed the infringement of having avoided hot press operation that camera is caused.
The control signal of camera is sent from cell phone mainboard, directly the camera module 1 on the glass substrate is controlled by the ITO cabling on the glass substrate 4.Cell phone mainboard utilizes the flexible circuit board (FPC from the LCD, Flexible Printed Circuit) 3 are connected with LCD and communicate by letter, control signal on the cell phone mainboard is connected on the LCD by FPC 3, then by the ITO cabling 4 on the LCD glass substrate, be connected respectively to LCD device drive chip and webcam driver chip (being arranged in camera module 1), thereby reach the purpose of cell phone mainboard control LCD and camera.Fig. 5 is the structural representation of cell phone mainboard control camera module of the present invention, as shown in Figure 5, the pin of respectively controlling on the cell phone mainboard is connected with each respective pin on the webcam driver chip with LCD device drive chip respectively, ways of connecting is that pin indicates identical interconnecting, and can realize the purpose of cell phone mainboard control LCD and camera.
Need to prove,, do not limit the particular location of camera module 1, only otherwise the demonstration that influences LCD gets final product as long as camera module 1 of the present invention is positioned on the LCD 2.
What above-mentioned facility scheme illustrated is the direct-connected mode of mobile phone cam and cell phone mainboard, the present invention also can directly be connected mobile phone cam with the LCD chip for driving, and webcam driver chip and LCD chip for driving integrated, main frame is by the control to the LCD chip for driving, realization is to the control of webcam driver chip, thereby realize control, below this technical scheme is described by concrete example to camera module of the present invention.In this example, camera module 1 is connected with LCD chip for driving (LCD driving IC), LCD driving IC and camera control IC is integrated, the shared IC of LCD and camera also controls the camera module.
Referring to shown in Figure 3, binding position 6 at the camera module, still utilize conductive material ITO matured photoetching process on the LCD glass substrate, on ITO, etch ITO cabling 4 as shown in FIG. in advance, LCD driving IC is coupled together with the bottom solder joint of shooting module, LCD driving IC and camera control IC integrate, the shared IC of LCD and camera, the camera mode of hot pressing, camera module 1 is bundled on the binding position 6 of glass substrate and camera by ACF (anisotropic conductive film), camera signals sends from cell phone mainboard, arrive integrated IC by FPC 3, and then directly the camera module on the glass substrate is controlled by the ITO cabling on the glass substrate 4.Pad between LCD driving IC and the camera module 1 is extended to 6 places, binding position as Fig. 3 with camera bottom solder joint as shown in Figure 4, thereby the pressure and the high temperature that prevent the pressure head that produces in the binding procedure cause damage to camera.
Fig. 6 is another structural representation of cell phone mainboard control camera module of the present invention, as shown in Figure 6, the present invention is sent by cell phone mainboard the control signal of camera module 1, send to by flexible circuit board on the drive IC of display, by the drive IC inside of display control signal is handled then and be decomposed into two paths of signals, wherein one the tunnel control LCD, another road control camera.Need to prove that the control pin on the cell phone mainboard is pressed the corresponding connection of the label shown in the figure with the pin on the drive IC of display, and the pin on the drive IC of display is connected with LCD, camera respectively and gets final product.
The present invention has put down in writing a kind of mobile phone simultaneously, includes camera, and camera wherein uses aforesaid side's method to be connected with cell phone mainboard or lcd driver.
Need to prove that above-mentioned is to be the explanation that example is carried out with the mobile phone, technical scheme of the present invention is equally applicable to PDA, the MP4 equal-volume is less and have in the handheld device of LCDs and camera, realizes identical in principle and the above-mentioned mobile phone example.
The above is preferred embodiment of the present invention only, is not to be used to limit protection scope of the present invention.
