Description
Technical field
A kind of display color temperature automatic regulating apparatus and method, it is by the coupling arrangement in the display, signal conversion device, central processing unit, display control unit, display device, and near display device colour temperature induction installation constitutes a circulation system with a computing machine and a signal connecting line, and can reach the effect of the automatic colour temperature adjustment of display.
Background technology
Under the scientific civilization progress, the mankind distant place can be transmitted or the signal transition that is stored in the memory media is a signal of video signal, no matter in work, recreational use, can be reached our needs by image reproduction, wherein display has become most important element.
What display was exported is image, and the mankind are its users, still input end is exactly eyes, eyes have light color, blueness or green and dark or brown because of gene relationship, as shown in Figure 1, what really change eye color is prepupillary iris, because iris itself has color, light color is higher to the faint light line sensitivity, and dark better to the high light tolerance.
So it is different and different with regard to the above-mentioned ethnic group gene of essential factor in adjustment that display manufacturer manufactures display, and required adjustment and be the colour temperature that display is exported, what is meant by colour temperature, suppose to have a Utopian black object (Black Body), when we provide heating power to this black object, it can produce radiation/radiation, and it is our human eye visible (these are exactly light) that this electromagnetic wave that radiates out has frequency spectrum partly.When the heating power of different temperatures was supplied with toward black object, the energy of the light that radiation is come out and spectrum allocation may (color of light) also can different these temperature.It is exactly the colour temperature that we often say.At display, it is warm partially that low colour temperature is exactly the red partially inclined to one side Huang of color, and high colour temperature is exactly that color is blue partially colder.In general, standard color temperature is 5000K, so display also answers adjustment to 5000K.But, user's difference buyer gives manufacturing plant because of can giving required color temperature value, can adjust its colour temperature and plant to adjust key OSD on the display pannel earlier and manufacturing plant is general, and respond to the colour temperature mode in addition with colour temperature induction installation 6 and respond to, and induction mode is determined the output color temperature value in addition, come is exactly that to be provided it to think with the user be the standard color temperature display again, as standard model, and it is identical with its output valve of naked eyes adjustment with sample for the personnel of manufacturing plant, so seem to reach user's demand, but in fact truly have following shortcoming:
1, part is combined many in the display, and through the loop complexity, though adjust its colour temperature to the required color temperature value of user with display pannel OSD, adjustment does not later reach the still many of adjustment value because of error rate and adjustment personnel empirical value and error and ambient light interference factor make.
2, the user provides it to think to be the standard color temperature display, as standard model, and identical with sample for the personnel of manufacturing plant with its output valve of naked eyes adjustment, but identification still has a little deviation to color because of everyone, and empirical value is different again, thus adjustment come out still have the also inevitable of deviation.
3, with after above-mentioned two kinds of mode adjustment, if user's order is most platform displays, and when use in same visual space, promptly can find the difference of every shown colour temperature of display, so can allow the user find the dealer or to make the row quality control not good, make dealer or fabricator so commercial image impaired.
Summary of the invention
The object of the present invention is to provide a kind of display color temperature automatic regulating apparatus and method, can adjust the colour temperature of display automatically, to overcome defective of the prior art.
The object of the present invention is achieved like this: a kind of display color temperature automatic regulating apparatus and method, and it comprises:
One coupling arrangement can provide signal input and output;

Described signal connecting line is for corresponding to data bus d-sub, universal serial bus USB, wire rods such as numerical digit vision interface DVI, audio-visual interface AV.
By apparatus and method of the present invention, can reach following advantage at least:
1, minimizing work injury:
Display QC personnel are because the colour temperature adjustment needs for a long time closely by display for a long time, and expend a large amount of eyesight and adjust colour temperature, accumulate over a long period and cause eye injury down easily, because colour temperature adjustment work causes, not only adjust personnel's visual impairment, display making factory also needs to undertake infringement to this work injury and fills up responsibility, and utilizes apparatus and method of the present invention, do not needed the consume of people's eyesight, so almost can avoid causing aforementioned injury fully.
2, simplify manpower:
Tradition colour temperature adjustment is owing to be the manpower adjustment, so OSD adjusts the key on adjusting display pannel, also must test again with the colour temperature induction installation, article one, producing apparent is many two procedures of colour temperature adjustment at least, promptly much essential two or above personnel, and utilize apparatus and method of the present invention, and the full automation operation, colour temperature is adjusted personnel and therefore can be omitted.
3, increase the adjustment degree of accuracy:
Tradition colour temperature adjustment is owing to be the manpower adjustment, except adjusting personnel's empirical value, and physiological structure difference and psychological factor, increase and adjust error, and utilize apparatus and method of the present invention, the full automation operation, circulation is adjusted to standard value, and degree of accuracy is adjusted significantly than tradition and promoted.
4, promote quality
Because the display interior part is numerous, deviation ratio is inevitable, and aforementioned manpower is adjusted shortcoming if can't improve, and quality promptly can't promote, and utilizes apparatus and method of the present invention, can reach nearly a hundred per cent degree of accuracy, so significantly promote quality.
