Embodiment 1

[0024] see figure 1 with figure 2 , a device for testing visual characteristics of a display, including a base 1, an optical fiber support body 2, an optical fiber 3 and a CCD4, the base 1 includes a jig 11 and legs (not shown in the figure), and the jig 11 is provided with an adjustment device 111, The fiber support body 2 is provided with several fiber installation holes 21 .

[0025] see image 3 , the optical fiber supporting body 2 is a hemispherical shell, the inner wall of the hemispherical shell is deposited with a light absorbing layer, and several groups of optical fiber mounting holes 21 are arranged at equal angles on the optical fiber supporting body 2, such as one set every 5°, each Groups of optical fiber mounting holes can be connected into an arc shape that passes through the apex of the fiber support body 2. The adjacent fiber mounting holes 2 in each group of optical fiber mounting hole groups have the same spacing, that is, the same angle. One is set at ...

Abstract

The invention discloses a display visual characteristic testing device, which comprises a base (1), an optical fiber bearing body (2), a CCD (4) and a plurality of optical fibers (3), wherein the optical fiber bearing body (2) is connected onto the base (1); the optical fiber bearing body (2) is a hemispherical shell and is buckled on the base (1) in an upside down mode; each optical fiber (3) isconnected between the CCD (4) and the optical fiber bearing body (2); a plurality of optical fiber mounting holes (21) matched with the optical fibers (3) are uniformly arranged in the optical fiber bearing body (2); one end of each optical fiber (3) is arranged on the optical fiber bearing body (2) through the optical fiber mounting hole (21); and the base (1) is provided with a fixing device forfixing a to-be-tested display. The display visual angle characteristic testing device is used for measurement on the visual angle characteristics of the display.

Description

technical field [0001] The invention relates to the technical field of display performance parameter testing, in particular to a display visual characteristic testing device. Background technique [0002] In recent years, flat-panel display technology has been greatly developed. Flat-panel displays have penetrated into many aspects of people's life and work. The performance parameters of the display itself are improving day by day, but the testing methods for evaluation have not been greatly developed. When the user watches the display from different angles, the perceived brightness, contrast and color are different, and this visual characteristic correlation is called visual characteristic. [0003] The commonly used method for testing the visual characteristics of displays is to use an optical detector (single probe: it can be a luminance test probe or a spectral test probe), and the computer system issues instructions to drive the detector with a motor (theta angle change...
