Embodiment Construction

[0050] Embodiments of the invention will now be described in detail and illustrated by way of diagrams in which like reference numerals refer to like elements throughout. The present invention is explained below in conjunction with the embodiments and the corresponding drawings.

[0051] As shown in FIG. 1 , an image display device 1 includes a bracket 3 installed at its bottom and a screen module supported by the bracket 3 , and the degree of movement of the upper portion of the screen module 2 is used as a reference swing.

[0052] As shown in Figure 2, the swing measurement system according to the present invention includes: a swing measurement unit 10, which converts the swing displacement into an electrical signal when the image display device swings; The output signal of the measuring unit 10 is analyzed, the received signal is analyzed, the pre-swing variable is calculated, and the degree of swing is estimated / displayed.

[0053] The arithmetic processing unit 100 may be...

Abstract

A system and method for measuring the degree of a wobble of an image display device are disclosed. The system can quantitatively measure the degree of a wobble of a screen module of an image display device, resulting in the implementation of increased reliability of measured wobble data. The system can adjust the height of the image display device irrespective of the appearance of the product model, such that it can be widely applied to a variety of product models. The system is loaded on the support, and moves to another location, such that it can be easily adapted to measure the wobble of a large-sized product having difficulty in motion, resulting in greater convenience of use.

Description

technical field [0001] The invention relates to a system and method for measuring the swing degree of an image display device, in particular to a system and a method for quantitatively measuring the swing degree of an image display device. Background technique [0002] In recent years, image display devices such as monitors have become thinner and smaller. Fig. 1 shows the appearance of a general-purpose image display device and explains a conventional wobble measurement method. According to FIG. 1 , an image display device 1 includes a large-sized thin screen module 2 and a bracket 3 , and the screen module 2 is supported by the bracket 3 . In order to make the product have a good appearance to meet user needs, the bracket 3 is manufactured with a smaller size. [0003] Compared with the bracket 3, the screen module 2 has a larger size. If the user operates the panel on the screen module 2, the screen module 2 will swing or break down, which is inconvenient for the user t...
