Abstract
The invention discloses an intelligent television (TV) remote control device provided with an optical touch tablet. A traditional method mechanical key-press is canceled and replaced with the miniature optical touch tablet. A near-infrared light-emitting diode (LED) is inlaid in the touch tablet to irradiate the surface of the touch tablet, and in addition, a complementary metal-oxide-semiconductor transistor (CMOS) image sensor and a corresponding optical focusing system are arranged to detect the displacement between a figure and a contact surface of the touch tablet. When the figure moves on the surface of the touch tablet, the remote control device can detect the displacement motion of the figure and sends a displacement instruct of a corresponding direction to an operation system of a TV. An elastic pressure switch is installed on a base seat support of the optical touch tablet, the optical touch tablet can be pressed and rebounded, a 'confirm' instruct can be thus sent to a TV system, and good man-machine interaction is achieved.
Description
Technical field
The present invention relates to the field of remote control of intelligent television, relate in particular to a kind of optical touch plate that uses as the remote controller of the Navigation Control of intelligent television.
Background technology
The trend of television set " high Qinghua ", " networking ", " intellectuality " has been complied with in the arrival of intelligent television.Intelligent television refers to as smart mobile phone, has the full open model platform, carried operating system, can be by user's program of providing of the third party such as installation and uninstall, game service provider voluntarily, come constantly the function of colour TV is expanded by this class method, and can realize such class colour TV of surfing the web by netting twine, wireless network.
Intelligent television needs more human-computer interaction with respect to traditional tv, mainly realize by remote controller at present.The user uses a teleswitch and realizes the movement of cursor, determines to wait action.But the navigation feature key of the TV remote controller of the overwhelming majority still uses the mechanical key of 4 direction types.There is operating lag in it, and the problems such as operation inconvenience can't bring good human-computer interaction to experience to the user as handset touch panel or computer mouse, more and more are not suitable with the demand of intelligent television development.
Summary of the invention
In order to overcome the deficiency of existing TV remote controller, the purpose of this invention is to provide a kind of novel touch control manner is that TV remote controller realizes conveniently Navigation Control.
TV remote controller provided by the present invention has been cancelled the mechanical key of 4 direction types, and replaces with a small-sized optical touch plate.The contact size that the external dimensions of optical touch plate is equivalent to thumb and remote controller when pressing.The built-in near-infrared LED of touch pad shines the touch pad face, has in addition CMOS image sensor and corresponding optical focusing system to survey the contact-making surface of finger and touch pad.When finger contact optical touch plate was also mobile, remote controller just can detect the displacement action of finger, and sends corresponding displacement commands to the operating system of TV.Be furnished with the elastic pressure switch on optical touch plate base support, the optical touch plate can be pressed and rebound, and so just can send " a determining " instruction to system.This design that remote navigation and definite function are integrated in a button meets user's use habit very much.Realize that by contact and slip touch pad the navigation of cursor can greatly reduce the frequency of pressing mechanical key in addition, and reaction is sensitiveer, can bring better operating experience to the user.

Embodiment
Below in conjunction with embodiment and accompanying drawing, invention is elaborated.But embodiments of the present invention are not limited to this.In accompanying drawing, identical mark represents same parts.For better understanding, parts shown in the drawings are to schematically show, and they are drawn in proportion, and namely the parts of this accompanying drawing do not represent full-size(d), these full-size(d)s are all known for those of ordinary skills, therefore here are not described in detail.
Fig. 1 is the Intelligent TV remote controller schematic diagram with the optical touch plate.Optical touch plate 2 replaces the centre position that original 4 direction mechanical keys are positioned in Intelligent TV remote controller 1, and when handgrip was held remote controller, the thumb of left hand or the right hand can touch the optical touch plate relatively easily.
Fig. 2 is the assembly structure decomposing schematic representation of optical touch plate.Sleeve 3 also allows the agent structure 5 of touch pad can carry out the micro-displacement of stroke up and down for the agent structure 5 of optical touch plate provides fixed support in addition.The watch crystal cover plate of optical touch plate is cut-off visible light saturating infrared fileter 4, its 50% cut-off wavelength at 700nm between 1000nm.Filter 4 is processed by filter glass, and its material itself has certain damage resistant characteristic and mechanical strength.Because filter ends visible light, so the internal circuit of optical touch plate and mechanical structure are invisible from the outside, thereby can not affect the attractive in appearance of TV remote controller in addition.Flexible PCB 6 is connected touch pad with the main circuit board of TV remote controller, control for touch pad provides signal transmission and power supply.Elastic pressure switch 8 is placed in bottom bracket 7 centers, and after normal assembling on withstand the agent structure of touch pad.When the finger presses touch pad, elastic switch 8 is compressed, and triggers " a determining " signal and issue intelligent television by remote controller.After finger loosened touch pad, at this moment elastic switch 8 resiliences and jack-up touch pad agent structure 5 did not trigger any signal.
Fig. 3 is the schematic diagram of optical touch plate.Be built-in with near-infrared LED 9 in optical touch plate agent structure 5, optical focusing lens 10 and CMOS image sensor 11.To between 1000nm, its light radiation scope can cover whole touchpad surface to the Infrared wavelength of the emission of near-infrared LED at 700nm, and the near infrared light that sends can pass the filter of touchpad surface, and is not discovered by human eye.When the finger contact touch pad, the infrared image of its contact-making surface reflection just focuses on CMOS image sensor 11 by optical lens 10.Here the object space focal plane of the optical system that consists of of optical lens 10 and CMOS image sensor 11 is just on the outer surface of touch pad.Be noted that in addition and will remove the cutoff filter that common CMOS surface loads.Because optical touch plate of the present invention is only launched and is surveyed near infrared signal, so only use the CMOS of intrinsic to get final product.By with only need to survey the movement of finger with the touch pad contact-making surface, so the resolution of CMOS image sensor need not be very high, be equal to or less than VGA (640x480) and get final product.In order to judge the moving direction of finger, need to be in processor loading algorithm analyze the displacement of the average light bright area of near-infrared image, simple visual impact Processing Algorithm just can realize here.When touch screen surface was slided, mobile direction and the stroke of finger was detected simultaneously when finger, and the communication transfer by remote controller and TV is to the TV operation system, the control with regard to realizing intelligent television is navigated like this.
Above-described embodiment is better embodiment of the present invention; but embodiments of the present invention are not limited by the examples; any other does not deviate from the change of making under Spirit Essence of the present invention and principle; modify; substitute, combination is simplified; all should be the substitute mode of equivalence, within being included in protection scope of the present invention.
