Embodiment
For making the object, technical solutions and advantages of the present invention clearly, below in conjunction with accompanying drawing, the embodiments of the present invention are explained in detail.But, persons of ordinary skill in the art may appreciate that in each embodiment of the present invention, proposing many ins and outs to make reader understand the application better.But, even without these ins and outs with based on the many variations of following embodiment and amendment, each claim of the application technical scheme required for protection also can be realized.
The present invention is for solving the problems of the technologies described above, and the invention provides a kind of LCD screen luminance test instrument, composition graphs one, is described in detail the present embodiment.
In Fig. 1, irradiation unit is irradiation unit 8, objective table comprises base for supporting 13 and multiple spot loading stationary platform 11, base for supporting 13 is regulated to make its level, sample is placed on multiple spot loading fixed pan 11, fixed head or hold-down nut is adopted to be fixed on multiple spot loading fixed pan 11 by tested article, movement unnecessary when preventing from measuring.Irradiation unit is regulated to regulate backboard 2 to make adjustable radiation source 6 be positioned at the top of tested article, moving right position guide rail 8 again makes adjustable radiation source 6 move to correct position above sample, trimming handle 12 can be adjusted again if not accurate enough during detection, regulate adjustable radiation source 6 directly over tested article after, start formally detect.In testing process, can separately through the distance regulating upper-lower position adjustable diameter and screw adjusting handle 1 to change adjustable radiation source 6 and tested article, also adjustable radiation source 6 can be regulated separately to change the intensity of irradiating light, also can the two regulate, to obtain different test datas simultaneously.
Control system and part implementation process can be manipulated be in the present embodiment, opening device power supply, enters touch screen interface, and equipment enters running status, software has three functions, first function is definite value set-up function, mainly adjusts for the illuminance definite value required for LCD screen, illuminance is adjusted to " 100LUX ", " 200LUX ", " 300LUX ", " 400LUX ", " 500LUX ".Second function is accurate calibration function, is precisely to correct respectively the brightness value in above-mentioned setting.3rd function is universal test function, is first by the definite value of brightness adjustment to setting, clicks " Test " button, enter into test interface, select the desired value of carrying out required for you testing, click corresponding button, enter into concrete test page.
The concrete using method of definite value set-up function is: to set 100LUX, and direct button click enters into corresponding test interface, and click " 100LUX " on the left side, then brightness is directly adjusted to " 100LUX " by equipment.The concrete using method of accurate calibration function is: the calibration of definite value brightness: what this function completed is customize the brightness value set precisely to correct, namely when definite value is tested, more accurate by the pick up calibration of equipment self, click " calibration " button, enter into " calibration " interface, select the definite value needing calibration, for definite value brightness settings 100LUX, namely need to calibrate " 100LUX ", first, under standard transducer being placed in light source, four the button adjustment brightness of screen lower left side are pressed." F-UP ": lighten fast, can grow and press, and " F-DOWN " dims fast, can grow and press, " S-UP ": slowly lighten, can only crawl, and " S-DOWN " slowly dims, can only crawl, after brightness adjustment to 100LUX, then the sensor of our equipment is placed on present position, then clicks " OK " button, just complete the calibration of 100LUX, the rest may be inferred.
The concrete using method of universal test function is: the universal button clicking main interface, enters test interface, in desired value frame, input desired value, and then click " run " button, equipment, by automatically adjusting according to desired value, after adjusting to the right place, automatically locks.If there is fortuitous event midway, " stop " button please be click and stop.
Radiation source in the present embodiment is D65 tunable light source, and color temperature value is 6500K, and brightness range can be provided to be 0-2000lux.
Structural design of the present invention is flexible, simple to operate, can realize the running fix of six direction up and down all around, tested article can be fixed placement on objective table, fine setting and the levelness that can carry out In-plane position during detection regulate, and ensure the accuracy that detection up-to-date style grade is set up.Be furnished with luminance brightness sensor, can calibrate light-source brightness value, precision can be provided to be 0.5lux.The present invention also can be used as the matrix of multiple irradiating and detecting device, saves the time changing irradiation unit when detecting, increases work efficiency.
The locating device mentioned in this specific embodiment, article carrying platform and irradiation unit profile have certain physical construction; physical construction function described in the present embodiment is one of possibility; therefore other physical constructions that can realize the various functions of claim different all should fall into protection scope of the present invention; such as locating device can adopt " V belt translation+electric rotating machine " to combine, a kind of mode comparatively simply and easily in adopting manual adjustments just to implement.
