Abstract
The utility model discloses a television receiver circuit capable of displaying different working states. Through the extension of a VFD fluorescence display module in the existing television receiver circuit, an internal power circuit, a micro processing unit MCU and a drive circuit are utilized to realize the real-time display function for various working states of the television receiver, not only the integral aesthetic of the television is reinforced, but also the occurrence of the faulty operation by users is avoided. Meanwhile, because of modularized design, the failure rate of a completing machine is decreased. When used in other circuit designs, the television receiver circuit capable of displaying different working states can simplify the circuit design, avoid repeated designs, and raise the work efficiency.
Description
Technical field
The utility model relates to a kind of TV set circuit, specifically, relates to a kind of TV set circuit that shows the various operating states of television set.
Background technology
Traditional television set all by after pushing on the remote controller " screen shows " key, could show the operating state of current TV on television screen, it is very inconvenient to operate.Owing to can not watch the current various operating states of TV in real time, cause misoperation of users probably, influence normally watching of TV programme.
Summary of the invention
In order to overcome the deficiency that television set in the prior art can not show various operating states, the utility model provides a kind of VFD fluorescence display module general, intelligence, realized Presentation Function to television set work at present state, it is cooperated high-grade television set designs such as rear-projection TV, make television set more intelligent, more attractive in appearance, and can guarantee the simplification of circuit structure.
In order to solve the problems of the technologies described above, the technical solution adopted in the utility model is: set up a VFD fluorescence display module in original TV set circuit, can the various operating states that television set is current be presented on the VFD fluorescent display screen, described VFD fluorescence display module mainly comprises:
One power circuit is for the inside modules chip provides required power supply power supply;
One microprocessing unit MCU, the control signal that host CPU is sent receives, through its inter-process, the output display control signal;
One drive circuit receives the display control signal that microprocessing unit MCU sends, and drives the VFD fluorescent display screen and shows.
Wherein, include a transformer in the described power circuit, this transformer can change into direct current+5V voltage and exchange 4.3V and two kinds of voltage signals of direct current-30V; Described drive circuit has then adopted a slice PT6311 chip.
Compared with prior art, the beneficial effects of the utility model are: by set up VFD fluorescence display module in existing TV set circuit, utilize its inner power circuit, microprocessing unit MCU and drive circuit, realized real-time Presentation Function to the various operating states of television set, not only strengthen the overall aesthetics of television set, and avoided the generation of user misoperation.Simultaneously, owing to adopt modularized design, reduced the failure rate of complete machine.Use it in other the circuit design, circuit design is oversimplified, avoid design iterations, increase work efficiency.
Description of drawings
Fig. 1 is the physical circuit figure of the utility model VFD fluorescence display module inside.
Embodiment
Below in conjunction with the drawings and specific embodiments the utility model is described in further detail.
The TV set circuit of various operating states that shows disclosed in the utility model realizes by setting up VFD fluorescence display module in existing TV set circuit, its inside modules mainly is made up of power circuit, microprocessing unit MCU and drive circuit, referring to Fig. 1.
When the user pressed button on the remote controller, host CPU (M37281EKSP chip) received this signal, by bus I
2The microprocessing unit MCU of C in VFD fluorescence display module transmits control signal and data-signal.In this VFD fluorescence display module, microprocessing unit MCU has adopted a slice PIC16C73B chip to be realized, its 14 pin receives the control signal among the control bus SCL, and 15 pins receive the data-signal among the data/address bus SDA.The data message that MCU sends according to host CPU, contrast its inner corresponding tables of data, send control command by pin one 1～13 to drive unit (having adopted a slice PT6311 chip), thereby driving the VFD fluorescent display screen shows in the relevant position, show television set present located operating state, as HDTV, VIDEO, VGA and TV etc.Simultaneously, the VFD fluorescent display screen can also show signs such as television channel, the length of one's sleep, 3D surround sound switch and product brand.
In addition, also include power circuit in VFD fluorescence display module, this power circuit general+5V direct current induces through transformer T and exchanges the grid power supply that 4.3V voltage is given the VFD module; Simultaneously, generation-30V direct voltage is chip for driving PT6311 power supply.
By in original TV set circuit, setting up VFD fluorescence display module, realized real-time Presentation Function to the various operating states of television set, strengthened the visuality of television set.Certainly; above-mentioned explanation is not to be to restriction of the present utility model; the utility model also is not limited in above-mentioned giving an example, and variation, remodeling, interpolation or replacement that those skilled in the art are made in essential scope of the present utility model also should belong to protection range of the present utility model.
