Embodiment Construction

[0023] In the related art, the screen brightness detection device includes an X-direction adjustment mechanism, a Y-direction adjustment mechanism, and a Z-direction adjustment mechanism, and the brightness detection device is arranged on the Z-direction adjustment mechanism. By adjusting the X-direction adjustment mechanism, the Y-direction adjustment mechanism, and the Z-direction adjustment mechanism, the brightness detection device can be moved to each area to be detected on the curved screen for brightness detection.

[0024] When performing brightness detection on each area to be detected of the curved screen, it is necessary to ensure that the optical center line of the brightness detection device is perpendicular to the surface of each area to be detected on the curved screen, so that the brightness detection device can detect the brightness of the curved screen. However, since the curved screen generally includes a plane area and a curved area, the use of the X-directi...

Abstract

The invention provides a screen brightness detection device, and relates to the technical field of optical detection. The screen brightness detection device comprises an X-direction adjusting mechanism, a Y-direction adjusting mechanism, a Z-direction adjusting mechanism and a brightness detection mechanism. The Y-direction adjusting mechanism is arranged on an X sliding block of the X-direction adjusting mechanism, and the Z-direction adjusting mechanism comprises a Y sliding block provided with the Y-direction adjusting mechanism; the brightness detection mechanism comprises a driving devicearranged on a Z sliding block and a brightness detection device connected with the driving device, and the brightness detection device swings relative to at least one direction of the X direction, the Y direction and the Z direction under the driving of the driving device. According to the screen brightness detection device, through the arrangement of the driving device, the brightness detectiondevice can be driven to swing relative to at least one direction of the X direction, the Y direction and the Z direction, so that the brightness detection device is perpendicular to the surface to bedetected of a curved screen, and the brightness detection precision of the curved screen is ensured.

Description

technical field [0001] The invention relates to the technical field of optical detection, in particular to a screen brightness detection device. Background technique [0002] In the manufacturing process of the curved screen, in order to ensure the quality of the curved screen, it is usually necessary to use a screen brightness detection device to detect the brightness of the curved screen. However, the existing screen brightness detection equipment can only detect the plane area in the curved screen, and cannot detect the curved area of ​​the curved screen, resulting in low detection accuracy. Contents of the invention [0003] An embodiment of the present invention provides a screen brightness detection device, which is used to improve the detection accuracy when detecting the brightness of a curved screen. [0004] An embodiment of the present invention provides a screen brightness detection device, including an X-direction adjustment mechanism, a Y-direction adjustmen...
