Abstract
The invention relates to a connecting circuit between an infrared touch screen and a television. The connecting circuit comprises an infrared touch screen, a liquid crystal television and a PC (personal computer); wherein the infrared touch screen is fixed on the surface outer frame of the liquid crystal television by sealed double-sided viscous sponge; the PC is connected with the liquid crystal television by a HDMI (high-definition multimedia interface) cable or a VGA (video graphics array) and audio cable for transmitting video and audio signals; the PC is connected with the infrared touch screen by a serial port cable for transmitting control signals. By the connecting circuit disclosed by the invention, an ordinary display can be changed into a touchable display.
Description
Technical field
The present invention relates to a kind of connecting circuit, relate in particular to the connecting circuit between a kind of infrared touch panel and the televisor.
Background technology
Infrared touch panel is a kind of being used for to change display into a large-scale mutual display device; And liquid crystal TV set is as one in the people's daily life visual product that can watch various channel programs or other effects.
How the two being combined is the problem that the technician will solve.
Summary of the invention
The technical issues that need to address of the present invention have provided the connecting circuit between a kind of infrared touch panel and the televisor, are intended to solve the above problems.
In order to solve the problems of the technologies described above, the present invention is achieved by the following technical solutions:
The present invention includes: infrared touch panel, liquid crystal TV set; Also comprise: a PC; Described infrared touch panel is fixed on the surperficial outside framework of liquid crystal TV set by the biadhesive sponge of sealing; Be connected transmission of video and sound signal with tone frequency channel wire with HDMI line or VGA between PC and the liquid crystal TV set, connect transmission of control signals with Serial Port Line between PC and the infrared touch panel.
Compared with prior art, the invention has the beneficial effects as follows: a usual display can have been become a tangibly display.
Description of drawings
Fig. 1 is a module map of the present invention.
Embodiment
Below in conjunction with accompanying drawing and embodiment the present invention is described in further detail:
As seen from Figure 1: the present invention includes: infrared touch panel, liquid crystal TV set; Also comprise: a PC; Described infrared touch panel is fixed on the surperficial outside framework of liquid crystal TV set by the biadhesive sponge of sealing; Be connected transmission of video and sound signal with tone frequency channel wire with HDMI line or VGA between PC and the liquid crystal TV set, connect transmission of control signals with Serial Port Line between PC and the infrared touch panel.
Because about 15 meters of HDMI line and VGA line transmission signals limiting distance, about 20 meters of Serial Port Line transmission signals limiting distance, about 30 meters of tone frequency channel wire transmission signals limiting distance, when if the distance during the integral device installation and design between PC and the LCDs surpasses limiting distance, then need between described PC and liquid crystal TV set, add a HDMI amplifier and HDMI extender (also claiming HDM I extender) or VGA extender and (comprise the VGA extender, VGA+ Serial Port Line extender and VGA+ tone frequency channel wire extender) prolong the distance of signal transmission, thus reach the effect of signal normal transmission.
The condition that the present invention will at first need infrared touch panel and televisor set to reach is to select the infrared touch panel and the televisor of same size to make their viewing area overlap.Infrared touch panel is made up of glass and infrared induction framework double-layer structure, and mounting means is to be fixed on the surperficial outside framework of liquid crystal TV set by the biadhesive sponge that seals.
Because touch-screen is to be embedded in the wall, so connecting line all is in wall, transposing or upgrade connecting line and can compare difficulty again after installing, so in the ordinary course of things, can stay many netting twines or VGA line and tone frequency channel wire fully during wiring, prevent of the work of the fault effects of HDMI line, can guarantee that touch-screen normally moves in the very first time to touch-screen.With needing after all installations the infrared touch panel driver is installed on main frame.
After infrared touch panel and two kinds of product set of liquid crystal TV set, will reach the effect of Comprehensive Control touch-screen, principle of work of the present invention is:
Owing to be covered with infrared receiving tube and infrared transmitting tube around the infrared touch panel, these infrared tubes are arranged the position relation one to one that is on the surface of television display screen, form a light net that becomes by infrared ray cloth, enter infrared that the infrared light net stops the somewhere when receiving as object (can be hand or any touch object of finger, band gloves), the ultrared power that the reception infrared tube of the both direction anyhow of this point receives will change, and equipment just can know where touch by the variation of understanding ultrared reception condition.
Infrared touch panel is transferred to the PC server by Serial Port Line with touch signal after receiving touch signal, reaches the function of mouse control main frame; The PC server again by HDMI line or VGA line and tone frequency channel wire with vision signal and audio signal transmission in LCDs, reach the function that shows host picture.When infrared touch panel is worked same in a flash in, have only a pair of infrared tube (referring to that the corresponding power valve of physical location and receives only pipe) carrying out datamation, circuit is by high-frequency data acquisition reaches the effect of rapid reaction to infrared tube.
The main way to manage of internal staff is exactly the PC server management device that Telnet connects touch-screen.
The control mode of client's operation is to click touch-screen.
The effect of set product of the present invention:
Infrared touch panel and computing machine and display can be formed best interactive system.Because infrared touch panel passes through the design of hardware and the programming of software, a usual display has also just become a tangibly display.Infrared touch panel is very small to the influence of image sharpness, if do not use the glass that is used to protect display surface, the display sharpness is reduced to zero.The user can carry out touch operation in touch screen surface with hand or any touch object of finger, band gloves, and needn't worry that the touching medium or the plated film on surface are scratched.
Can reach any icon of clicking on the display behind the install driver, for example: Query Information, program request Flash, playing animation etc.
The effect that the present invention reaches is exactly to be equivalent to utilize the icon on the click display to start needed program, for example: touch with hand or felt pen and just to be equivalent to a mouse click left button, to press and motionlessly be equivalent to a mouse click right button in 4 seconds, press can drag after motionless and select window etc.
The present invention can accomplish to upgrade in time to the content on the display and startup effect etc. equally by the Telnet main frame, also makes the client lose fraicheur problem with regard to having eliminated content can not change for a long time and occurs.
