Background
In the present day that display technology is rapidly developed, liquid crystal display devices and OLED display devices are widely used as mainstream products in display products, and various electronic products have their shadows. Because the problem of parameter changes such as brightness and chromaticity can occur when the display panel is watched under different visual angles, visual experience is influenced, and the display panel needs to be subjected to a series of tests and measurements before entering the market so as to ensure the quality of the display panel.
In the lcd panel, the chrominance information and luminance information at different viewing angles have larger variations than the chrominance information and luminance information at the best viewing angle, and in order to resolve the dark viewing angle or dark color point problem of the lcd panel, the luminance information and chrominance information of the panel at different viewing angles need to be accurately measured.
In the OLED display panel, the chromaticity and brightness of the display panel are determined by the output combination of each sub-pixel, but due to the production difference, the brightness between the pixels may also be different, which may cause the color precision to be reduced and the color on the display panel to be uneven. Compared with a liquid crystal display panel, the OLED display panel has smaller chromaticity and luminance changes at different viewing angles, but the display chromaticity and the display luminance at the optimal viewing angle still slightly change, so that the luminance information and the chromaticity information of the panel at different viewing angles also need to be accurately measured.
In the Quantum Dot (QD) polarizer project, in order to improve the problem of yellow large viewing angle, the diffusion particles are dispersed in the quantum dot system to expand the blue viewing angle, so that the brightness information at different viewing angles after the diffusion particles are dispersed in the quantum dot system needs to be tested. The current detection device is difficult to meet the requirements, and cannot test the optical information of the display panel or the quantum dots under different visual angles and different dimensions.

Detailed Description
The following description of the various embodiments refers to the accompanying drawings that illustrate specific embodiments in which the invention may be practiced. The directional terms mentioned in the present invention, such as [ upper ], [ lower ], [ front ], [ rear ], [ left ], [ right ], [ inner ], [ outer ], [ side ], are only referring to the directions of the attached drawings. Accordingly, the directional terms used are used for explanation and understanding of the present invention, and are not used for limiting the present invention. In the drawings, elements having similar structures are denoted by the same reference numerals.
The invention aims at the technical problems that the existing measuring jig can only realize the measurement of the panel to be measured under the condition of single visual angle or small detection angle change and can not realize the light-emitting detection of the display panel or other objects to be measured under multi-dimensional visual angles, and the embodiment can solve the defect.
Fig. 1 is a schematic structural diagram of a multi-dimensional view angle measuring fixture according to the present invention, which includes: a support unit and a detection probe 101; the support unit includes a base 102, a light-transmitting area 103, a guide rail 104, a slider 105, a telescopic member 106, and an elastic hose 107.
The detection probe 101 is connected with the base 102 through the elastic hose 107, the detection probe 101 is fixed in the vertical direction through a probe fixing structure on the telescopic component 106, a light collection area of the detection probe 101 is arranged opposite to the light transmission area 103, one end of the light collection area of the detection probe 101 is in contact with the base 102, and the contact width is a, so that a supporting point can be provided when the detection probe is inclined at an angle, and the measurement of the inclined angle is convenient to realize; the inspection probe 101 may be CA310, CA410 or other inspection probes meeting the inspection requirements, which is not limited in the present invention.
The light transmission area 103 is a through hole, is located in the base 102, and is arranged opposite to the light collection area of the detection probe 101, so that detected light directly enters the detection probe 101 after passing through the light transmission area, and detection of the detected light is realized.
The guide rail 104 is disposed outside the light-transmitting area 103 and includes at least two circular rails, the two circular rails are arranged on the base 102 at a certain distance, and the diameter of the circular rail located on the inner side is smaller than that of the circular rail located on the outer side.
