Within the scope of shield.
The present invention proposes a kind of picture frame TV.
Referring to Fig. 1, in one embodiment, above-mentioned picture frame TV includes liquid crystal display 100 and test module 200, mould is tested
Block 200 includes data transmission unit 230, the first memory cell 220 and control unit 210.
Wherein, data transmission unit 230 is used to input user's image data to be shown.First memory cell 220 is used for
Store user's image data.Control unit 210 be used for when receiving the burn-in test trigger signal of liquid crystal display 100, output with
The control signal of liquid crystal display 100 corresponding to user's image data, so that liquid crystal display 100 shows picture corresponding to user's image data.
It is preferred that the output end of data transmission unit 230 is connected with the input of the first memory cell 220, the first storage
The output end of unit 220 is connected with the input of control unit 210, and the control terminal of control unit 210 is controlled with liquid crystal display 100
End connection, the triggering end of control unit 210 are used to input burn-in test trigger signal.
Here, liquid crystal display 100 can be UD screens (resolution ratio 3840*2160), FHD screens (resolution ratio 1920*1080)
Or HD screens (resolution ratio 1366*768) etc., the resolution ratio of liquid crystal display 100 is not limited herein.
Test module 200 can be that picture frame TV is original, for testing the burn-in test mould of the degree of aging of liquid crystal display 100
Block 200.One difference of this test module 200 and existing burn-in test module 200 is exactly to be stored in this test module 200
There is user's image data to be shown.So, in this picture frame TV, when opening the ageing testing function of test module 200,
User's picture corresponding to user's image data can just be shown by liquid crystal display 100, be equivalent to and realized electronic photo frame function.
That is this picture frame TV, which need not increase specific movement, can be achieved with electronic photo frame function, cost is relatively low.
Specifically, when using this picture frame realizing television electronic photo frame function：
First, user's image data corresponding to user's picture to be shown is inputted to first and deposited by data transmission unit 230
In storage unit 220, the first memory cell 220 stores user's image data；
Then, control unit 210 receives the burn-in test trigger signal of liquid crystal display 100, and is touched according to the burn-in test
Signal the user's image data for reading and being stored in the first memory cell 220；
Finally, control unit 210 exports the control signal of liquid crystal display 100 corresponding with user's image data, and liquid crystal display 100 is aobvious
User's picture corresponding to showing above-mentioned user's image data, realizes electronic photo frame function.
It should be noted that the usage scenario of above-mentioned picture frame TV, can be after picture frame TV dispatches from the factory first in use,
It can be that picture frame TV dispatches from the factory using after several times, not be limited herein.It is noted that picture frame electricity is being used again
During depending on realizing electronic photo frame function, data transmission unit 230 can input new user's image data to the first memory cell 220
In, to meet the needs of user shows different pictures.
In one embodiment, when the first memory cell 220 receives new user's image data, the first memory cell
220 automatically delete original user's image data.
In another embodiment, data transmission unit 230 is additionally operable to input and deletes instruction, when the first memory cell 220 connects
When receiving deletion instruction, corresponding user's image data is deleted.Specifically, when the first memory cell 220 receives new use
During the image data of family, original user's image data is still preserved, only when receiving deletion instruction, just by corresponding user
Image data is deleted.
It should be noted that when user's image data capacity that the first memory cell 220 receives reaches its storage limit
When, the first memory cell 220 will no longer receive new user's image data.Hereafter, if memory cell deletes certain customers' picture
Data, then it can continue to new user's image data.
Please continue to refer to Fig. 1, in one embodiment, above-mentioned first memory cell 220 is additionally operable to storage picture frame TV and dispatched from the factory
When the initial picture data that carry so that test module 200 when being not received by user's image data, can also realize that aging is surveyed
Function is tried, strengthens applicability.
Such as user's first before this picture frame TV is bought, it is necessary to detect the degree of aging of liquid crystal display 100 of picture frame TV,
To be confirmed whether to buy.Now, because the ownership of picture frame TV is also not belonging to user's first, if user's first inputs privately owned picture
Into picture frame TV, then the problem of may bringing privacy leakage.However, if picture frame TV comes with user's image data in itself,
Then user's first is without privately owned picture is inputted into picture frame TV, it is possible to the degree of aging of liquid crystal display 100 of picture frame TV is detected,
It is very convenient.
Referring to Fig. 2, in another embodiment, picture frame TV also includes the second memory cell 240, the second memory cell
240 are used to store the initial picture data carried when picture frame TV dispatches from the factory.
It should be noted that in the present embodiment, control unit 210 triggers letter in the burn-in test for receiving liquid crystal display 100
Number when, corresponding with the initial picture data control signal of liquid crystal display 100 is also exported, so that the display initial picture of liquid crystal display 100.Compared with
Goodly, the output end of the second memory cell 240 is connected with the auxiliary input terminals of control unit 210.
Specifically, in the present embodiment, when control unit 210 receives the burn-in test trigger signal of liquid crystal display 100,
Detect first in the first memory cell 220 and whether be stored with user's image data.If it is stored with user in the first memory cell 220
Image data, then control unit 210 control liquid crystal display 100 show user's image data corresponding to user's picture；If the first storage
There is no user's image data in unit 220, then control unit 210 controls liquid crystal display 100 to show initial picture.So, no matter
Under the conditions of which kind of, picture frame TV can maintain ageing testing function.
Referring to Fig. 3, in one embodiment, test module 200 also includes burn-in test interface 250, burn-in test interface
250 supply voltage and burn-in test trigger signal for inputting liquid crystal display 100, to improve the applicability of picture frame TV.
