Abstract

Disclosed is a television set utilizing a three-button design to realize basic operations. The television set of the utility model comprises a television set body, a control unit, and a button portion, wherein the button portion comprises a switch/standby button, a program source/program +/volume+ button, and a menu/program-/volume- button. In the television set of the utility model, a single button integrates multiple functions to replace the conventional single button that has single function, thereby improving the intelligentization of the television set, compressing the space of the button portion, making it possible for realizing industrial standardization for the button portion, and saving the decoding chip resource used by the reception signaling device.

Description

A kind of three buttons design realizes the television set of basic operation

Technical field

The utility model relates to a kind of television set, comprises the television set that utilizes three buttons to realize the television set basic operation.

Background technology

When watching TV play, the user has been accustomed to using a teleswitch to operate, and the frequency of utilization of television set body button is more and more lower, but indispensable.Generally have seven buttons on traditional television set: program source, menu, program add, program subtracts, volume adds, volume down and treat switch.

From Design of Dies, we will consider to contain the position of keypad on mould of these seven keys, and will be because it has taken certain space, different owing to constructing for different moulds, corresponding keypad size also will be done corresponding adjustment, has brought very large inconvenience to industry standardization like this.

In addition, on circuit design, the voltage that the TV SKD decoding chip receives is generally the highest to be 3.3V, because seven more than buttons carry out voltage distribution between from 0V to 3.3V and will guarantee not can misoperation, require the interval of certain voltage value between per two adjacent magnitudes of voltage, distribute so the minimum function that will receive to realize with two master chip input ports each button.For the not too large keypad of effect in user family, caused the waste of the resources such as decoding chip.

The utility model content

The technical problems to be solved in the utility model provides the television set that the design of a kind of use three buttons realizes basic operation, utilize an input port to reach the purpose that realizes traditional seven keypress functions of television set by three buttons, when saving mainboard decoding chip input port resource, the keypad printed board is dwindled over half, for the design keypad standardization reference is provided.

For solving the problems of the technologies described above, this experiment new television models employing television set body, control unit and the button section that is arranged on the television set body form, it is characterized in that: described button section comprises button one, button two and button three, described button one, button two and button three connection control units, each button carries out respectively multiplexing at least two functions, wherein button one multiplexing program source, program adds adds with volume; Button two multiplexing menus, program subtracts and volume down; Three of buttons have increased switch key, and treat that switch is multiplexing; Described switch key is that button one and button two are carried out the switching of multiplexing function.

Further, described television set control unit exists and the special identification decision mechanism condition of wanting the decoded signal agreement.

The novel principle of this experiment is: described television set basic operation refer to seven functions by program add, program subtracts, volume adds, volume down and standby operation; Each button carries out respectively multiplexing at least two functions, wherein button one multiplexing program source, program adds adds with volume; Button two multiplexing menus, program subtracts and volume down; Three of buttons have increased switch key, and treat that switch is multiplexing; Described switch key is that button one and button two are carried out the switching of multiplexing function; Described television set control unit exists and the special identification decision mechanism condition of wanting the decoded signal agreement.

The novel beneficial effect of this experiment is: television set button section substitutes seven traditional buttons by three buttons, and in the unbated situation of function, input signal reduces, and is conducive to receive the used decoding chip use amount of signal and reduces the resource of having saved this type of decoding chip; Each button is given more function, meets the intelligentized trend of household electrical appliances, has more aesthetic appearance; The minimizing of button means the minimizing that button section version takes up space on mould, for the standardization direction of television set industry outer mold provides very large effect.

Description of drawings

The utility model is described in further detail below in conjunction with accompanying drawing and example:

Fig. 1 is the utility model three buttons design television set plane graph;

Fig. 2 is the utility model functions of television set modular structure figure.

Embodiment

A kind of three buttons design shown in Figure 1 realizes the television set of basic operation, formed by television set body 1, control unit 2, button section 3, button section 3 is comprised of three parts, three buttons comprise button 1, button 25, button 3 more than 6 parts, 36 liang of long buttons can be realized standby and start operation more than second; Switching by button 36, the function of button 1 and button 25 these two keys circulates realization " program source " and " menu ", " program adds " and " program subtracts ", " volume adds " and " volume down " successively, simultaneously near the sequence of positions of key part the function prompt of these two keys, the functional status of these two keys of prompting user appear at screen; The functional status that shows does not have the operation of button then can automatically disappear within two seconds; In program source or menu function open mode, utilize the software control program to add, program subtracts, volume adds, the multiplexing directionkeys of volume down, volume adds and the multiplexing acknowledgement key of volume down.

Figure 2 shows that this experiment new television models functional block diagram, button section 3 is as input module, change input voltage signal by switch closure, control unit 2 is combined by keypad circuit and decoding chip, receive input voltage signal, decoding chip translates the corresponding signal of telecommunication, comes eight basic operations of control inputs module.

Should be pointed out that for those skilled in the art, under the prerequisite that does not break away from this patent principle, can also make some improvement and change, such as the position that changes button section or change function under three buttons.Such conversion all drops within the protection range of the present utility model.

Claims

1. button design realizes the television set of basic operation, formed by television set body (1), control unit (2) and the button section (3) that is arranged on the television set body (1), it is characterized in that: described button section (3) comprises button one (4), button two (5) and three (6) three buttons of button, described button one (4), button two (5) and button three (6) connection control units (2), each button carries out respectively multiplexing at least two functions, wherein button one (4) multiplexing program source, program adds adds with volume; Button two (5) multiplexing menus, program subtracts and volume down; Button three (6) has then increased switch key, and treats that switch is multiplexing; Described switch key is that button one (4) and button two (5) are carried out the switching of multiplexing function.
