Description

IPS LCM light leakage measurement fixture

Technical field

The utility model relates to the technical field of IPS screen light leakage measurement, specifically to an IPS LCM light leakage measurement fixture.

Background technique

IPS screens have the advantages of large viewing angles, true colors, and fast response speeds. They are favored by a large number of users. More and more monitors use IPS screens. However, a major disadvantage of IPS screens is that after being deformed by force, the screen will change. Yellow (i.e. IPS light leakage) affects the user experience. When the panels are assembled into a complete machine, they will be more or less deformed under the influence of some pressure. During the production process, it was found that some panels have better tolerance to stress deformation, while some panels have poor tolerance. A little deformation will cause large areas to turn yellow. Currently, there is no good jig to test the panel's sensitivity to force deformation.

Furthermore, side pads are detachably fixed on the middle parts of both sides of the back of the panel with screws, and upper pads are detachably fixed on the middle part of the upper end of the back of the panel with screws. The two ends of the cross beam are connected to the corresponding side through screws. The side pads are detachably and fixedly connected, and the upper end of the vertical beam is detachably and fixedly connected to the upper pad through screws.

Furthermore, the two ends of the cross beam are respectively provided with transverse elongated installation grooves arranged along the length direction of the panel, and the upper end of the vertical beam is provided with a vertical elongated installation slot arranged along the height direction of the panel.
