For above-mentioned television set, the present invention also provides a kind of television set is carried out the method for burn-in test, and this method may further comprise the steps: receive the control signal that enters aging mode; Respond described control signal, RGB alternative diverter switch is switched to RGB test signal passage, and start close beta signal generator module generation RGB test signal; The RGB test signal is shown to display screen by RGB test signal channel transfer.
Television set is carried out in the scheme of method of burn-in test in the present invention, this method comprises that also aging mode withdraws from, and this method may further comprise the steps: receive the control signal that withdraws from aging mode; Respond described control signal, RGB alternative diverter switch is switched to television set rgb video signal passage; The video input signals of each passage of television set is shown to display screen by the rgb video signal channel transfer.
Television set is carried out in the scheme of method of burn-in test in the present invention, when described television set is carried out aging mode state or normal condition, also comprise, the storage of present mode is so that start back system goes to read information in the current storage earlier again.
Television set is carried out in the scheme of method of burn-in test in the present invention, the control signal that enters aging mode and withdraw from aging mode sends by user remote controller.
Television set is carried out in the scheme of method of burn-in test in the present invention, the control signal that enters aging mode is by importing user remote controller successively " MENU "; " 0 "; " 0 "; " 0 " four buttons send, and the described control signal of aging mode that withdraws from is by importing user remote controller successively " MENU ", " 1 "; " 1 ", " 1 " four buttons send.
Television set is carried out in the scheme of method of burn-in test in the present invention, the close beta signal generator module is by the aging signal of realizing that open and close and selection prestore that is provided with to 16 system register.
Television set is carried out in the scheme of method of burn-in test in the present invention, the 5th of described system register is set as 0, and the close beta signal generator module is closed, not output signal; Be set as 1, portion's test signal generation module is opened, the output test signal; Various test signal output can be selected by different settings in the 0-4 position of described system register.
After implementing technical scheme of the present invention,, need only need not utilize the system of self just can carry out burn-in test, reduce production cost widely by external instrument equipment to television set because television set carries testing source.And, in ageing process, when the television set needs are mobile, do not need to move in addition again some external equipments yet, and only television set is moved just, also can enhance productivity greatly
In addition,, can remember nearest mode of operation, in ageing process, still be aging mode after the start again owing to contain memory in the system for TV set, simple to operation.
Moreover, only need just can make the inner burn-in test signal that produces of television set by shirtsleeve operation by the original remote controller of giving the client that is equipped with of television set, improved production efficiency.

Embodiment
In the television set of the present invention, comprised a signal processing system, Fig. 1 shows the signal processing system structural map, this signal processing system comprises receiver module, control module, close beta signal generator module, video signal processing module, rgb signal alternative diverter switch, wherein:
Receiver module is in order to receive control signal;
Control module, in order to judging the signal received whether for entering the aging mode signal, and the gating passage of control rgb signal alternative diverter switch, and the switch of close beta signaling module and video processing module;
Video processing module is in order to handle the video input signals of television set external video passage;
The close beta signal generator module, the aging signal of testing in order to generation, one 16 system register 0x8274 is arranged in this close beta signal generator module,, can produce 32 kinds of aging mode signals altogether by the setting different to the 0-4 position of 0x8274, just can select different burn-in test signal output then as required, as shown in table 1, select 00000, then access a full black burst, select 10001, then access a GTG signal.

Table 1
Rgb signal alternative diverter switch, in order to select is the rgb video signal of exporting by after the external channel video input signals process Video processing of television set, or exporting to screen by the RGB test signal that the internal signal generation module in the signal processing system produces shows.
Figure 2 shows that the flow chart that TV is carried out ageing testing method, in step 201, at first with the television set normal boot-strap, television set shows the signal of outer video signal after video signal processing module is handled, if do not have outer video signal, then screen display " no signal ".
In step 202, the staff of factory imports the button of establishing in advance by user remote controller.Be example with present the use, if press remote controller successively " MENU ", " 0 ", " 0 ", " 0 " four buttons, in step 203, the receiver module in the signal processing system responds this signal, and this signal is passed to control module.
Control module judges whether this signal is the signal that enters the burn-in test pattern in step 204.If enter then execution in step 205 of aging mode, on the contrary execution in step 206 then.
If being judged as, control module enters the burn-in test signal, the activation of television set aging mode and test pattern flow for displaying figure as shown in Figure 4, RGB alternative diverter switch is by the current input signal passage under the normal condition, switch to internal signal generation module passage, then, the 5th of 0x8274 register who is used to control the internal signal generation module in the signal processing system is set as 1 by 0, and the close beta signal generator module is opened, the output test signal.Because system register 0x8274 stored 32 kinds of aging mode signals, as long as it is controlled, just can access a new value per 3 seconds, GTG for example, Quan Baichang, test signals such as colour bar with control module.In step 207, these test signals show through exporting to display screen after the RGB alternative diverter switch of gating, just can see on screen that finally change once visual per 3 seconds of demonstration, finally form a circulation.
Finish if factory is aging, want to allow television set withdraw from aging mode, same reason, only need the staff to import remote controller successively " MENU "; " 1 "; " 1 "; " 1 " four buttons, in step 203, the receiver module in the signal processing system responds this signal; and this signal passed to control module; in step 204, control module judges that this signal is for withdrawing from aging mode, in step 206; RGB alternative diverter switch switches back to the television video input signal channel, and this signal is shown through exporting to display screen after RGB alternative diverter switch of gating.
After factory's aging mode activates or withdraws from, system can information write-in memory EEPROM with current factory's aging mode or non-aging mode in, even need in the ageing process like this TV is closed the start operation, after the start, system goes to read the information among the EEPROM earlier once more.Figure 4 shows that example, if be at aging mode before the shutdown, still need to be operated under the aging mode after the start again, just need not reuse the user remote controller input " MENU ", " 0 ", " 0 ", " 0 " these 4 buttons, system directly enters aging mode.If before the shutdown is normally to watch pattern, then play the video content of current video signalling channel.
