The invention adopts the above technical scheme, shows a positioning black square in display equipment picture center, and lead to
It crosses the alignment probe detection of color analyzer and then judges whether that center alignment is current aobvious according to the detection data of color analyzer
Show equipment picture, and then notifies that test host is acted accordingly.The present invention, which cooperates automation to import picture positioning comprehensively, to be needed
It asks, effectively improves picture positioning accuracy, promote adjustment image quality, improve misalignment.Picture positioning accuracy judgement of the invention
Can be automatic by software program, reduce manual operation error and fault.The present invention reduces production line manpower and entire activity duration, drop
The risk of low human error.Therefore the present invention can reduce factory's manufacturing cost, improve production efficiency, promote product quality.
Detailed description of the invention
The present invention is described in further details below in conjunction with the drawings and specific embodiments；
Fig. 1 is a kind of display equipment picture of the invention center location structure schematic diagram；
Fig. 2 is the flow diagram of a kind of display equipment picture center positioning of the present invention and automatic testing method.
Specific embodiment
As shown in the figures 1 and 2, the invention discloses a kind of display equipment picture center positioning and automatic testing method,
Itself the following steps are included:
Step 1, it generates the dark registration pattern 2 of a fixed size and is shown in the picture center of display equipment 1；Tool
Body, the display equipment 1 is display or television set.
Step 2, the probe 31 of color analyzer 3 is directed at dark registration pattern 2, and keeps probe 31 and display equipment 1
Display panel distance be not more than 15mm；
Step 3, X value, Y value and the LV value of color analyzer 3 are obtained；
Step 4, whether judge LV value less than 0.5: when LV value is greater than or equal to 0.5, centralized positioning unsuccessfully sends positioning and loses
Signal is lost to testing host；When LV value is less than 0.5, positioning pass signal is sent to testing host；
Step 5, test host receives signal and carries out subsequent processing:
Operator is notified to manually adjust 31 positions of probe or control driving after test host receives positioning failure signal
Probe 31 rotation motor action with and execute step 3；
The test result based on color analyzer 3 carries out display equipment 1 after testing host and receiving positioning pass signal
Parameter adjustment adjusts the beam detection that finishes.
Further, the dark registration pattern 2 of step 1 is black squares.
Further, the side length of the black squares is equal to 31 sizes of probe+left side nargin+right side of color analyzer 3
Side nargin.
Further, 31 size of probe of the color analyzer 3 is 40mm, and left side nargin and the right nargin are
10mm, the side length of black squares are 60mm.
About positioning black squares picture side length concrete norm requirement:
Specifically, it can be seen that square picture side and central point apart from the smaller the better, are less than from the data of following table 1
Or it is best equal to 10mm, index parameter (SPEC) requirement can be met；
| 0% | 25%White | 50%White | 75%White | 100%White | |
