Multi-station rotary Demura equipment

Abstract

The invention discloses multi-station rotary Demura equipment. The multi-station rotary Demura equipment comprises part replacing windows, Mura compensation devices and a rotary disc. 2n sets of bearing devices for containing display panels are symmetrically arranged on the rotary disc rotationally, one set of bearing devices in any two adjacent sets of bearing devices are located on the part replacing windows, the other set of bearing devices are located below the Mura compensation devices, when the rotary disc rotates by 360/2n degrees, the bearing devices located on the part replacing windows rotate below the Mura compensation devices, and the bearing devices located below the Mura compensation devices rotate to the part replacing windows. The multi-station rotary Demura equipment is simple in structure, convenient to use and high in automation degree, the Mura compensation devices and the rotary disc are integrated in a platform, in cooperation with the bearing devices, part replacing of the display panels is completed while Mura compensation of the display panels is achieved, and therefore the working efficiency of the equipment is improved.

Description

technical field [0001] The invention relates to a display panel Demura device, which belongs to the technical field of display panel detection, in particular to a multi-station rotary Demura device. Background technique [0002] In recent years, with the rapid popularization of household TVs, consumers have higher and higher requirements for LCD TV screens. The quality of the display panel in the LCD TV screen is the premise to ensure its high image quality. , It is difficult to control, and it is easy to cause Mura phenomenon (uneven brightness) in the production process, and bright spots or dark spots appear, that is, block-shaped traces in a certain area of ​​​​the display panel caused by differences in display brightness, thereby reducing the Displays the quality level of the panel. In order to eliminate the above-mentioned mura phenomenon, the display panel demura technology emerges as the times require. [0003] In the prior art, when using the Demura technology to e...

Problems solved by technology

The above-mentioned technical solution has the following technical problems: firstly, the invention does not disclose a complete technical solution of an automatic detection mechanism. According to the description of the above-mentioned comparative document, it is only known that the cylinder has three degrees of freedom, and what drives the cylinder and does not It is not disclosed; secondly, if the adjustment mechanism is used to adjust the position and height of the cylinder to achieve focus adjustment, it will inevitably cause inaccurate focus adjustment due to large amplitude adjustment, and may also cause damage to the camera; finally, the three-degree-of-freedom cylinder cannot meet the requirements of the Mura compensation system.
