Abstract

The invention belongs to the technical field of product testing, and particularly relates to a display module vibration testing system and method as well as a display module fixing tool. The fixing tool can be used for vibration testing of a display module of a notebook computer; grooves which can be used for placement of the screen parts of the display modules are formed in a base plate of the fixing tool; a first through groove which enables the circuit board part of the display module to pass through the base plate is formed in the bottom of each groove, so as to prevent the circuit board part from being damaged in the process of vibration testing; the fixing tool further comprises a cover plate connected with the base plate; the base plate and the cover plate are connected with each other to form a box body which can be used for simulating a shell of the notebook computer; the display module can be completely fixed inside the fixing tool, and vibration energy can be well transferred to the display module. By being matched with the vibration testing system and method aiming at the display modules, the vibration environment in which the notebook computer is positioned can be accurately simulated, and the obtained testing result can be used as the development basis of high-quality display modules.

Description

technical field [0001] The invention belongs to the technical field of product testing, and in particular relates to a display module vibration testing system, method and fixing tooling thereof. Background technique [0002] A display module used in a notebook computer is composed of an upper substrate assembly, a lower substrate assembly, a liquid crystal panel, a driving circuit board, a backlight module and other accessories. Among them, the backlight module is composed of an upper diffusion sheet, a lower diffusion sheet, an enhancement sheet, a light guide plate, a backplane, a plastic frame, and a light source. The various components of the display module are interconnected and interfere with each other. During the production and assembly, packaging and transportation, and customer use, the display module is transported and causes the display module to vibrate. [0003] The accumulation of small vibrations for a long time or intense vibrations may cause foreign matter...
