Description
Technical field
The present invention relates to the flat screen module field of flat panel TV, and in particular to one kind improves flat board using a plurality of gamma
The method of TV colour temperature uniformity.
Background technology
As flat panel TV market competition grows in intensity, each producer makes same model screen module color occur to reduce cost
The situation that temperature differs greatly.Conventionally, used using all screen modules of the gamma for same model, flat
The big situation of colour temperature difference just also occurs on plate TV, not only influences the subjective effect of TV, and influence the pin of TV
Sell.If by front-end control screen module the colour temperature uniformity of screen module is lifted using component, it is meant that cost will be big
Width increase.
The content of the invention
The purpose of the present invention is the deficiency being directed in above-mentioned background technology, there is provided one kind is improved using a plurality of gamma
The method of flat panel TV colour temperature uniformity, on the basis of existing flat panel TV and screen module do not increase any cost, by depositing
Storage transfers a plurality of gamma to lift the colour temperature uniformity of flat panel TV.
In order to reach above-mentioned technique effect, the present invention takes following technical scheme：Improved using a plurality of gamma flat
The method of plate TV colour temperature uniformity, comprises the following steps：
A. reference color temperature existing for screen module used in flat panel TV is determined；
B. reference color temperature existing for the screen module is subjected to divided rank；
C. gamma debugging is carried out to the screen module sample in each color temperature levels, the colour temperature after debugging is in what is required
In reference color temperature；
D. the corresponding gamma debugged out is incorporated into TV software；
E. test determines each screen module color temperature levels on production line, and corresponding gamma is selected in TV software, complete
Into subsequent production.
Preferably, in step a, the different big screen module of color temperature difference determines reference color temperature as object between individual.
Preferably, the reference color temperature for determining 50 cun of screen modules is 7000K~13000K.
Preferably, the colour temperature of described 50 cun screen modules is divided into three color temperature levels：7000K~9000K, 9001K
~11000K, 11001K~13000K；Screen module sample in each grade is subjected to gamma debugging, makes the screen of each reference color temperature
The colour temperature of module final output is 10000K；3 gammas for debugging completion are incorporated into TV software；Finally, test
Determine each to shield module color temperature levels on production line, corresponding gamma is selected in TV software, completes subsequent production.
The present invention compared with prior art, has following beneficial effect：Technical key point is color temperature difference
Different larger screen module is classified by colour temperature, then each grade screen module is carried out into gamma debugging and is incorporated into software, the root in production
Transferred according to the reference color temperature of individual screen and gamma is corresponded in software, the colour temperature of flat panel TV is in the colour temperature of requirement
In the range of, realize colour temperature uniformity.The present invention is on the basis of existing flat panel TV and screen module do not increase any cost, is led to
Cross storage and transfer a plurality of gamma to lift the colour temperature uniformity of flat panel TV, make the flat panel TV of same model screen module
After completing to produce, the colour temperature shown is controlled in the range of requiring, improves colour temperature uniformity.
