Testing device for projectors provided by the utility model is being used to projecting apparatus according to standard GB/T 24850-2010
When energy efficiency market is tested, test signal should according to display intrinsic resolution, the characteristic such as aspect ration difference and area
Not.Test signal should be consistent with tested projecting apparatus intrinsic resolution, aspect ration.The exfactory inspection test of projecting apparatus is general all dark
Carried out in room, the veiling glare illumination requirement in darkroom is less than or equal to 1lx (lx is unit of illuminance, i.e., every square metre of lumen number,
1lx=1Lm/m2), temperature meets 15 DEG C to 25 DEG C, and relative humidity is 25% to 75%, the power supply of projecting apparatus adjust to 220V,
50Hz, illumination photometer are proofreaded once again.
Projecting apparatus needs to be adjusted to original state before testing, chooses the most bright pattern that enterprise is recommended, passes through VGA (Video
Graphics Array, a kind of video transmission standard) projecting apparatus connected into computer, adjust intrinsic resolution and the gray scale of the limit eight
The state that level requires to standard, now using standard curtain 50.Common aspect ration has 16/9,16/10 and 4/3, no matter that
Aspect ration, require and 1 square metre of projected light area is adjusted out on screen, select complete white field signal, then measure again.
After projecting apparatus at least steady operation 5 minutes, using vertical plate type screen 60, required in projected area according to standard
Nine points (9 illumination test position schematic diagrames are as shown in Figure 5) measure successively and record illumination numerical value, and at that time
Start power.Respectively using full Red Square signal, complete green field signal and complete blue field signal, and measure the number of projected area central point
Value, carries out the calculating of color domain coverage ratio.After the completion of testing above, projecting apparatus enters holding state, carries out standby test, and record is treated
Acc power.Finally close projecting apparatus and power supply, test terminate.
Specifically, first will be to be measured when carrying out exfactory inspection test to table viewer using the testing device for projectors
Table viewer 701 (camera lens prefix type) be placed in top tray 702, standard curtain 50 is put down, slided by the support of bearing 706
Dynamic movable chassis 705, so as to realize the distance of adjustment criteria curtain 50 and table viewer 701, that is, realizes the regulation of focal length；
Control lifting support 704 to lift table viewer 701 by lift cylinder 703 again, make the projection of table viewer 701
Light beam is located at the center of standard curtain 50, so as to complete the regulation of height.Then intrinsic resolution and pole can be adjusted
Limit the state that eight GTGs require to standard.Standard curtain 50 is rolled to the top for being placed in projection screen.Weigh according to the method described above
The focal length and height of new adjustment table viewer 701,1 square is adjusted to according to the mark on vertical plate type screen 60 by projected area
Rice, select complete white field signal.Measured successively according to nine points of standard requirement in projected area and record numerical value, and it is complete
Measured into other experimental datas.
Specifically, when throwing top using the testing device for projectors projecting apparatus progress exfactory inspection test, need to remove first
First testboard 70, the first testboard 70 are to be placed on by the support of bearing 706 on the support frame of the testing device for projectors.
Then top to be measured is thrown into projecting apparatus 801 to be placed on upper flat plate 802, as shown in Figure 4.Standard curtain 50 is put down, opens and fixes
The buckle structure of bar 30, the projection screen is moved to by survey in frame 10 by fix bar 30 and sliding block 40 in a manual manner
After the desired position of projecting apparatus 801 is thrown on examination top, buckle structure is closed again, that is, realizes the regulation of focal length；Pass through hand wheel rotating silk again
Thick stick axle 804, make upper flat plate 802 under the accurate guiding of lead rail axis 803, top is thrown into projecting apparatus 801 is elevated to required height, makes
Its projected light beam is located at the center of standard curtain 50, so as to complete the regulation of height.Then intrinsic resolution can be adjusted
And the state that the GTG of the limit eight requires to standard.Standard curtain 50 is rolled to the top for being placed in projection screen.According to above-mentioned
Method readjusts the focal length and height that projecting apparatus 801 is thrown on top, and projected area is adjusted into 1 according to the mark on vertical plate type screen 60
Square metre, select complete white field signal.Measured successively according to nine points of standard requirement in projected area and record numerical value,
And complete other experimental data measurements.
The testing device for projectors is surveyed the standard curtain measured for the grey scale signal of the limit eight and for complete white field signal
The vertical plate type screen of amount is combined, and common aspect ration 16/9,16/10 and 4/3 is incorporated on one piece of vertical plate type screen,
For the projecting apparatus of different manufacturers production, by the adjustment of height and focal length, the device disclosure satisfy that each of different manufacturers
Kind model projecting apparatus efficiently and easily test by exfactory inspection.
Obviously, above-described embodiment is only intended to clearly illustrate example, and is not the restriction to embodiment.It is right
For those of ordinary skill in the art, can also make on the basis of the above description it is other it is various forms of change or
Change.There is no necessity and possibility to exhaust all the enbodiments.And the obvious change thus extended out or
Among the protection domain that variation is created still in the utility model.
