Description
Technical field
The invention belongs to photochromism energy measurement equipment technical field, relate to display screen photochromism energy measurement equipment, relate in particular to the gantry type four dimensional automatic measurement that is used for detecting automatically the photochromic performance of display screen.
Background technology
Along with development of technology, products such as TV, computer, mobile phone, camera use flat-faced screen more and more widely, and display area is increasing, and image is more and more clear.These display screens comprise LCD, PDP, LED display etc.
Flat-faced screen is just towards image fidelity, the image quality exquisiteness, and levels are rich, stereoscopic sensation is strong, and the direction of high brightness, high-contrast, wide visual angle, high-resolution develops.Some display screen mainly is LCD, a LED screen at present, and the visual angle is little, and brightness when watching image, contrast and color saturation increase and reduce along with the visual angle of watching, and the colourity error increases along with the increase at visual angle, and picture quality is reduced; And full frame color homogeneity also has much room for improvement.Need the colorimetric characteristics of these display screens is detected for this reason.
The instrument that detects the display screen colorimetric characteristics is made up of automatic test desk and chroma and luminance measurement instrument at present.Display screen and chroma and luminance measurement instrument are installed on the automatic test desk.The automatic test desk of prior art as shown in Figure 1, it is made up of chroma and luminance measurement instrument universal stage 01, two-dimentional mobile platform 02, elevating mechanism 03, measured piece erecting bed 04 and test desk base 06, two dimension mobile platform 02 comprises longitudinal moving mechanism 021 and transverse moving mechanism 022, two dimension mobile platform 02 is installed on the elevating mechanism 03, measured piece erecting bed 04 is installed on the longitudinal moving mechanism 021, and tested display screen is connected on the measured piece erecting bed 04.Measuring table is finished two dimension in the plane and is moved, and it is the twice of maximum detection screen size that mobile space requires.Chroma and luminance measurement instrument 05 is installed on the pivot arm 011 of chroma and luminance measurement instrument universal stage 01, and pivot arm 011 has a reciprocating mechanism 012, and the chroma and luminance measurement instrument can move up and down, and regulates the distance of chroma and luminance measurement instrument to display screen.Move tested display screen and rotate the angle and the lifting pedestal 06 of photochromic measuring instrument and tested display screen on universal stage 01 pivot arm 011 by two-dimentional mobile platform 02, finish the measurement at display screen uniformity of chromaticity and visual angle.There is following defective in prior art:
(1) complex structure, volume is big.The visual angle of the one dimension of this test desk is measured and the two-dimensional plane color homogeneity is measured and must be moved by the plane is two-dimentional in length and breadth, measuring instrument moves up and down, pivot arm rotates and five dimension athleticisms of hydraulic pressure base lifting are realized, its complex structure, occupation area of equipment is more than 4 times of tested display area, its visual angle is measured and is adopted chroma and luminance measurement instrument universal stage to rotate, the pivot arm turning radius is big, and increase with screen size, be generally high 3 times of tested display screen, tested screen size increases, photochromic measuring instrument rises De Genggao thereupon on the universal stage 01, the rectilinear motion space of two dimension mobile platform increases thereupon, makes test desk seem huge more.
(2) straight-line driving force is big.Two dimension is moved in length and breadth and will be driven objective table and the motion of tested screen, and elevating mechanism will drive the measured piece erecting bed and two-dimentional in length and breadth travel mechanism moves together, because volume is big, equipment is heavy, and required driving force is very big.
(3) automaticity is low.Chroma and luminance measurement instrument universal stage 01 and two-dimentional mobile platform 02 be not in unified coordinate system, be difficult to accurately adjust at three-dimensional the visual angle of coordinate points position and display screen, the degree of intelligence of measurement and use operation is low, measuring accuracy and poor reliability, be difficult for the duplicate measurements condition, consistance is poor.Operation inconvenience, measuring speed is slow.
(4) kinetic stability is poor.Measuring table is amesiality, because measured piece erecting bed Heavy Weight, the equipment center of gravity of making is offset, and motion all will be born bigger gravity torque, has a strong impact on the stationarity of equipment moving.
(5) size of measuring object is big inadequately.The test desk application is subjected to restrictions such as structure, cost, and the photochromic performance that is difficult to be applied to larger sized display screen is measured automatically.
For the display screen industry that adapts to develop rapidly and the display screen chroma and luminance measurement demand that grows with each passing day, press for that measuring accuracy height, the measuring speed that can satisfy display screen colorimetric characteristics measuring system are fast, volume is little, cost is low, be adapted to the automatic test desk that various sizes display screen colorimetric characteristics is measured.
