Specific embodiment
Presently in connection with drawings and examples, the present invention is described in further detail, these attached drawings are simplified signal
Figure, the basic structure of the invention will be illustrated schematically only, therefore it only shows the composition relevant to the invention.
As depicted in figs. 1 and 2, a kind of naked eye screen test macro, comprising: platform and end of probe；It is installed on the platform
There is at least one display screen, several luminance meters are arranged at intervals in the end of probe, wantonly two brightness is calculated as one group；
One group of luminance meter can measure the brightness or/and coloration that viewpoint is corresponded on display screen, be carried out by multiple groups luminance meter
Calculate crosstalk and best view position analysis shows that screen.
End of probe is planar structure；Optionally, end of probe is arcwall face structure.
The central point of end of probe is overlapped with the central point of display screen, by adjusting end of probe height or end of probe and display screen
The distance between, the setting of the distance between end of probe and display screen determines that screen size is bigger according to screen size, detection
The distance between end and display screen adjusting range are bigger, so that end of probe intermediate point and display screen center are in same level
Luminance meter measuring accuracy is improved in face.
Luminance meter can adjust the angle, and the distance between display screen and end of probe are 1-5 meters.
In a preferred embodiment of the present invention, display screen is nine viewpoint cylindrical lenses formulas；
Optionally, display screen is two viewpoint liquid crystal lens formulas.
In order to achieve the above objectives, a kind of another technical solution that the present invention uses are as follows: test of naked eye screen test macro
Method, steps are as follows:
(1) adjustment end of probe central point fixes the distance between end of probe and display screen with display screen central point to being overlapped
It is 1 meter；
(2) one groups of luminance meters can measure the brightness or/and coloration that viewpoint is corresponded on display screen；
(3) it adjusts separately end of probe difference group luminance meter to measure, it is white at different points of view then to obtain display screen
It is poor to calculate white chromaticity for color chromaticity values；
(4) adjustment the distance between end of probe and display screen moves between 1-7 meters, and it is bright to adjust end of probe difference group again
Degree meter measures the brightness or/and coloration of different points of view on display screen, obtains the white chromaticity value at display screen different points of view,
It is poor to calculate white chromaticity；
(5) when luminance meter carries out brightness and colour measurement, different groups of luminance meters is adjusted and are measured, by comparing each viewpoint
Brightness determines best viewing angle with the distribution at visual angle.
The range at visual angle is -60 degree to 60 degree in step (5), and adjustment end of probe difference group luminance meter measures, then
White chromaticity value of the display screen at different points of view is obtained, it is poor to calculate white chromaticity, analysis shows that screen viewpoint is with viewing angle distribution
Crosstalk, the best viewing location of test that can be more accurate；
Each viewpoint is as follows with the 3D crosstalk formula of viewing angle distribution:
N=number of views
Average crosstalk formula is as follows:
Crosstalk minimum value is greater than 1, each maximum direction of viewpoint brightness with the smallest angle of crosstalk be it is corresponding, 0 degree is attached
Nearby the average value of three-dimensional crosstalk is 286.36%.
In the range of -60 degree surveyed are to 60 degree, the deviation of white field coloration is less than 0.05.
End of probe bottom is provided with bracket, is provided with device against shake on bracket, can have in luminance meter measurement process
There is stabilization effect, to improve test effect.
Based on the above description of the preferred embodiments of the present invention, through the above description, related personnel completely can be with
