The utility model has the technical importance that the utility model comprises a control signal source, an LED driving chip and an LED display screen, wherein the LED display screen is assembled on a front panel of a television; the LED display screen comprises an LED channel display device, an LED frequency spectrum graphics display device for audio signals; the current time display or the indoor temperature display or the display of start puzzle lock can also be added.
Description
Technical field
The utility model relates to a kind of LED display unit, especially a kind of LED display unit that is used for television set.
Background technology
At present, though can the indicated channel number on the display screen of television set and the size of volume, numeral that shows or image and picture are overlapping, influence people's visual effect.Therefore, people wish to have a kind of the demonstration with overlapping, the independent channel of picture and the appearance of the display unit of audible spectrum.
Summary of the invention
The purpose of this utility model is the deficiency that overcomes prior art, does not show with overlapping, the independent channel of picture and the LED display unit of audible spectrum image for television set provides a kind of.
Another purpose of the present utility model is to increase the demonstration of current time or demonstration or the coded lock of control television boot-strap or the combination of above-mentioned demonstration of indoor temperature in above-mentioned display unit.
To achieve these goals, can adopt following technical scheme: the same control signal source, LED chip for driving, the LED display of comprising of the technical program with prior art, its improvement is: this LED display is assemblied on the television set front panel, and it comprises that a LED channel digit shows and the LED frequency spectrum graphics of audio signal shows;
Described signal controlling source respectively with television set in the channel signals line be connected with audio signal wire; The signal controlling source interconnects by data wire DATA and LED chip for driving, and the signal controlling source also selects line STB to be connected with the LED chip for driving by clock line CLK with sheet; The LED chip for driving is connected by bit driver, segment driver and LED display respectively.Above-mentioned signal controlling source is MCU signal controlling source preferably, adopts single board computer also to be fine as the signal controlling source certainly.
Increasing an indoor temperature LED in the above on the said LED display shows, this indoor temperature LED shows with one and is arranged on indoor temperature sensor and is connected, and this temperature sensor is connected with said signal controlling source, just can be on above-mentioned display unit the temperature in the display room.
If on the basis of aforementioned schemes, the LED that increases a current time on LED display again shows that the LED of this current time shows and is connected with said signal controlling source, then can show the current time.
Can also increase a coded lock and show on above-mentioned LED display, this coded lock demonstration is connected with the power supply of television set and controls by one group of keyboard that is connected with the LED chip for driving.So just can prevent that children or other people from arbitrarily turning on television set.
The beneficial effects of the utility model are:
1. for providing a kind of, television set do not show and the display unit of audible spectrum image with overlapping, the independent channel of picture, thereby can make television set cancellation channel demonstration on curtain screen picture and volume demonstration numeral and visual originally, improve the appreciation quality and the effect of picture.
2., then increased television function and made user's life convenient if on above-mentioned display unit, increased the demonstration of room temperature, current time and coded lock.
3. its structure is very simple, and it is few therefore to increase cost.
The utility model is described in further detail below by drawings and Examples, makes it more clear.
