Embodiment Construction

[0031] The following will clearly and completely describe the technical solutions in the embodiments of the present invention with reference to the drawings in the embodiments of the present invention. Apparently, the described embodiments are only some of the embodiments of the present invention, but not all of them. Based on the embodiments of the present invention, all other embodiments obtained by persons of ordinary skill in the art without creative efforts fall within the protection scope of the present invention.

[0032] In the display production line, the uneven force on the display is eliminated by manually adjusting the screws that lock the product, thereby eliminating the Mura of the display. There is a problem that the adjustment cannot be completed at one time. It is necessary to detect the Mura while adjusting, which seriously affects the balance of the production cycle and cannot Ensure product consistency.

[0033] For this reason, this embodiment provides a ...

Abstract

The invention relates to the technical field of display screen machining, in particular to a method and device for online adjusting display screen Mura. The method comprises the following steps of shooting to obtain a picture of a display screen black frame with screws fixed; analyzing and obtaining the level of the display screen Mura of the picture; if the level of the display screen Mura is lower than the set qualified Mura level, analyzing the picture and obtaining the Mura position on the display screen; according to the Mura position, controlling a screwdriver to move to the screw position, corresponding to the Mura position, on the display screen; and through the screwdriver, twisting the screws on the screw position, and executing the S100 until the display screen Mura level is higher than or equal to the set qualified Mura level. According to the method and device for online adjusting the display screen Mura, through the technical scheme, the technical problems that an existing locking screw manual adjusting manner is adopted for removing display screen Mura, the production efficiency is low, product pace is affected, and product consistency is difficultly ensured are solved.

Description

technical field [0001] The invention relates to the technical field of display screen processing, in particular to a method and equipment for adjusting the Mura of a display screen online. Background technique [0002] The monitor belongs to the I / O device of the computer, that is, the input and output device. It is a display tool that displays certain electronic files on the screen through a specific transmission device and then reflects them to the human eye. [0003] Due to the inherent characteristics of the display screen, when the display screen is subjected to external force, under the same light source and the same background color, it will visually perceive different degrees of color difference, which is called mura in the industry. Use ND filters of different specifications to observe Mura, ND card (also known as NDfilter, light reduction film, ND filter). If no Mura is visible under the x% ND card, the Mura level is x% ND. (The severity of the ND card specificat...
