Abstract
The invention discloses a touch screen channel controller. The touch screen channel controller comprises a scalar processing chip, an ARM (Advanced RISC (Reduced Instruction Set Computer) Machines) processor, a USB (Universal Serial Bus) channel selection chip and a touch display screen, wherein the signal input end of the ARM processor is connected with the signal output end of the scalar processing chip; the signal output end of the ARM processor is connected with the USB channel selection chip; the USB channel selection chip is connected with the touch display screen. According to the touch screen channel controller, when an all-in-one machine of a touch screen is used as an independent display, namely when the all-in-one machine is connected with an external host signal source instead of an internal host signal source, the function of the touch screen can be automatically switched to a host system which is currently used along with the switching of the signal source, user operation is facilitated, the problem that an existing touch screen is only used for the all-in-one machine is solved, channels of the touch screen can be automatically switched, and the function of the touch screen can be used regardless of the situations.
Description
Technical field
The present invention relates to a kind of touch-screen channel controller.
Background technology
Touch-screen is also called " touch screen ", " contact panel ", it is an induction type display device that can receive the input signals such as contact, when certain position contacted on screen, the point that haptic feedback system on screen can press to operator according to the program of programming in advance, in order to replace mechanical push button panel, and lively interfacial effect can be produced by LCD LCD MODULE.
Touch-screen is as a kind of new computer input apparatus, and it is the simplest, convenient current, natural a kind of man-machine interaction mode.Along with growing with each passing day of multimedia information inquiry, people use touch-screen more and more, and touch-screen have sturdy and durable, reaction velocity fast, save space, be easy to many advantages such as man-machine interaction.Utilize this technology, as long as user just can realize host service function with the icon on finger lightly touch computer display or word, thus make man-machine interaction more simple and direct, this technology greatly facilitates the user that those are ignorant of computation.
Touch-screen widely uses now, and all with touch-screen on very great display device, the particularly all-in-one that is integrated together of display and host computer, all with touch function.But as integrated machine equipment, touch-screen is fixed on the computer host system inside all-in-one, can only be dull use in same system, can not share with other computer host systems.
If existing touch screen integrated machine is both when all-in-one use, again when independent display uses, under two kinds of use-patterns, touch-screen passage can only use under all-in-one environment, but can not use touch-screen when using under as independent display environment.
Therefore, necessary the deficiency solving prior art is improved to prior art.
Summary of the invention
The present invention provides a kind of touch-screen channel controller to solve above-mentioned prior art Problems existing.
The technical solution adopted in the present invention has: a kind of touch-screen channel controller, comprise scalar process chip, arm processor, USB channel selecting chip and touch display screen, the signal input part of described arm processor is connected with the signal output part of scalar process chip, the signal output part of arm processor is connected with USB channel selecting chip, and USB channel selecting chip is connected with touch display screen.
Further, described USB channel selecting chip comprises touch screen interface and the internal host system channel be connected with touch screen interface respectively and external host system passage, described internal host system channel and external host system passage are connected respectively the signal output part at arm processor, and touch screen interface is connected with touch display screen.
The present invention has following beneficial effect: present invention achieves touch screen integrated machine when using as independent display, namely external host signal source is connect, during without internal host signal source, touch screen function also can automatically switch to along with the switching of signal source in the host computer system of current use, user-friendly, solve the limitation that existing touch-screen can only use under all-in-one, the passage of the touch-screen that can automatically switch, no matter use in which kind of situation and can use touch screen function.
Accompanying drawing illustrates:
Fig. 1 is workflow schematic diagram of the present invention.
Fig. 2 is USB channel selecting chip structure schematic diagram of the present invention.
Embodiment:
Below in conjunction with accompanying drawing, the present invention is further illustrated.
Please refer to Fig. 1 to Fig. 2, a kind of touch-screen channel controller of the present invention, comprise scalar process chip, arm processor, USB channel selecting chip and touch display screen, the signal input part of arm processor is connected with the signal output part of scalar process chip, the signal output part of arm processor is connected with USB channel selecting chip, and USB channel selecting chip is connected with touch display screen.
In the present invention, USB channel selecting chip comprises touch screen interface and the internal host system channel be connected with touch screen interface respectively and external host system passage, internal host system channel and external host system passage are connected respectively the signal output part at arm processor, and touch screen interface is connected with touch display screen.
Workflow of the present invention is: scalar process chip judges that current using state is that touch screen integrated machine (connecing internal computer host signal source) still just thinks display (connecing external computer host signal source), by the Signal transmissions that judges to arm processor, the signal control USB channel selecting chip that arm processor transmits according to scalar process core.
If current use all-in-one (internal computer host signal source), then the USB passage pin set (1 or 0, judge according to USB channel selecting chip data handbook) corresponding to internal host system is opened it, other pathway closures; Just think that as current display uses (external computer host signal source), then the USB passage set (1 or 0, judge according to USB channel selecting chip data handbook) corresponding to external host system opened it, other pathway closures connect.Thus reach the object of touch screen signal passage bridge.
This functional realiey touch screen integrated machine is when using as independent display, namely external host signal source is connect, during without internal host signal source, touch screen function also can automatically switch to along with the switching of signal source in the host computer system of current use, user-friendly.
The above is only the preferred embodiment of the present invention, it should be pointed out that for those skilled in the art, can also make some improvement under the premise without departing from the principles of the invention, and these improvement also should be considered as protection scope of the present invention.
