Embodiment
For making the object of the embodiment of the present invention, technical scheme and advantage clearly, below in conjunction with the accompanying drawing in the embodiment of the present invention, technical scheme in the embodiment of the present invention is clearly and completely described, obviously, described embodiment is the present invention's part embodiment, instead of whole embodiments. Based on the embodiment in the present invention, those of ordinary skill in the art, not making other embodiments all obtained under creative work prerequisite, belong to the scope of protection of the invention.
Embodiment 1
Fig. 1 is the steps flow chart schematic diagram of the testing method of a kind of display unit that the embodiment of the present invention provides. See Fig. 1, the method comprises:
Step 10: in adjustment white balance parameter, the yield value of often kind of color is to respective saturation point;
Step 30: the brightness uniformity of test display apparatus.
It should be appreciated that display unit of the present invention can be any product or parts with display function such as display panel, Electronic Paper, mobile phone, panel computer, televisor, notebook computer, digital phase frame, navigating instrument; Thus, the method for the embodiment of the present invention may be used in the middle of the test step of any one product above-mentioned or parts.
It should be appreciated that the test of the brightness uniformity of display unit belongs to the part in the test step of display unit in above-mentioned steps 30. For example, the test process of the brightness uniformity of display unit can specifically carry out in the following manner: first, provides power supply input and display input to display unit so that display unit can show monochromatic picture; Then, on the light intensity detector measurement display plane that utilization distance display plane is predetermined distance (such as 1��20cm), each position place goes out light intensity; Finally, all positions are gone out the calculating that light intensity carries out uniformity coefficient, and by the test index comparing the brightness uniformity obtaining display unit with standard value. But, in other embodiments of the invention, step 30 can carry out the test of the brightness uniformity of display unit with reference to prior art by other specific implementations, and this is not limited by the present invention.
Above-mentioned steps 10 is understandable that, described white balance parameter such as can comprise red gain value, green gain value and blue gain value, red gain value when above-mentioned saturation point then refers to that display brightness is big as far as possible respectively, green gain value and blue gain value. Certainly, depending on the difference of display device type, the detailed process of adjustment can also have corresponding specific form, and this is not limited by the present invention. Wherein it should be appreciated that white balance parameter may carry out the setting of stdn after the completing of display unit, above-mentioned saturation point thus under general condition can be deviateed. Thus, the yield value of often kind of color in white balance parameter can be adjusted to respective saturation point by the operation of step 10 before the test of brightness uniformity, thus can eliminate white balance correction to the impact of the test result of brightness uniformity. It may be seen that the test result of brightness uniformity can be more accurate when display unit has relatively large brightness, the test result of this optical index can also relatively prior art and raise.It thus is seen that the embodiment of the present invention contributes to improving the accuracy of the test result of brightness uniformity, reduce the loss erroneous judgement of qualified product caused.

Step 30: the brightness uniformity testing described display unit.
It should be noted that, before step 10 and step 20 are all the brightness uniformity being executed in test display apparatus, and execution order to each other can be in no particular order.
It is understandable that, the testing method of the embodiment of the present invention, except comprising above-mentioned steps 10 and step 30, further comprises step 20: the brightness correlation parameter that all of display unit and preset value differ by more than predetermined threshold is adjusted to state when making display brightness maximum. Wherein it should be noted that, " brightness correlation parameter " refer in display unit any one or multiple to the influential setting parameter of display brightness; Such as, when this display unit is specially LCD TV, above-mentioned brightness correlation parameter comprises following any one or more: the 1. luminosity of the backlight in display unit; 2. the printing opacity brightness of the display panel in display unit; 3. the display comparison degree of display unit. Visible, the adjustment of these parameters can change display panel display brightness generally, thus the test of brightness uniformity is had an impact.
Also it should be noted that, above-mentioned preset value can be the display brightness demarcated in advance maximum time set(ting)value, it is also possible to be display unit preset value, and predetermined threshold value be set in advance allow deviation preset value scope. Thus, it is possible to only deviateing when set(ting)value exceedes pre-determined range at brightness correlation parameter and it adjusted, to simplify steps flow chart, and the working order avoiding display unit causes detrimentally affect. Certainly, depending on the difference of display device type, the detailed process of adjustment can also have corresponding specific form, and this is not limited by the present invention.
It is understandable that, brightness correlation parameter is adjusted to the overall lifting of the display brightness of display unit when state when making display brightness maximum is conducive to making test brightness homogeneity, thus contribute to improving the accuracy of the test result of brightness uniformity equally, reduce the loss erroneous judgement of qualified product caused.

Step 102: the saturation point calculating the yield value of often kind of color according to default picture signal;
Step 103: judge that whether the yield value of each color is consistent with respective saturation point;
Step 104: when the yield value of any one color and its saturation point are inconsistent, in white balance parameter, the yield value of this kind of color is adjusted to this saturation point.
For example, above-mentioned default picture signal can be the limit eight gray scale nine window signal of the prior art, thus this default picture signal first can be carried out numerical sample by the embodiment of the present invention in a step 101, then in step 102, calculate the saturation point of the yield value of often kind of color with existing saturation point account form.Thus, step 103 can judge that whether the yield value of each color is consistent with respective saturation point respectively, and concrete judgment mode can be such as judge whether difference between the two is less than predeterminated level; And step 104 when step 103 judges that the yield value of any one color and its saturation point are inconsistent, can carry out the adjustment of yield value according to the mode that display unit is given.
In addition, in other enforcement modes of the present invention, when the yield value of any one color of adjustment is to saturation point, it is possible to adopt the mode increasing progressively or successively decreasing to carry out the adjustment of yield value. Specifically, it is possible in a working cycle by yield value raise or reduce unit amount, and judge raise or reduce after display brightness whether in continuous rising; If continuing rising, continuing raised by yield value or reduce unit amount, if reducing first after lasting rising, conversely yield value being reduced or raising unit amount and end loop.
Thus, it is possible to use the relation between yield value and display brightness, fast yield value is adjusted to the level of saturation point, and do not need the calculating carrying out saturation point in advance, contribute to the lifting of processing efficiency.
