Abstract

The invention discloses a drawing performance test fixture and a drawing performance test method for a full-lamination display device. According to the drawing performance test fixture, a distance measurement unit and a pressure measurement unit are integrated on a test part, constantly-increasing drawing force is applied to a cover plate of a full-lamination display panel through the test part, the adhesion state of the cover plate of the full-lamination display panel and a TFT display module is observed at the same time, and data of the distance measurement unit and data of the pressure measurement unit are read at the moment when the cover plate and the TFT display module are separated; thus, the drawing force and the drawing distance of the full-lamination display device are measured at the same time, and the working efficiency is improved while the drawing performance of the full-lamination display device is effectively tested. By means of the drawing performance test method for the full-lamination display device, the drawing force and the drawing distance of the full-lamination display device are measured at the same time, and the working efficiency is improved while the drawing performance of the full-lamination display device is effectively tested.

Description

technical field [0001] The present invention relates to the field of display technology, in particular to a jig for testing pull-out performance and a method for testing the pull-out performance of a fully laminated display device. Background technique [0002] With the development of display technology, liquid crystal displays (Liquid Crystal Display, LCD) and other flat display devices are widely used in mobile phones, televisions, personal Various consumer electronic products such as digital assistants, digital cameras, notebook computers, and desktop computers have become the mainstream of display devices. [0003] Most of the liquid crystal display devices currently on the market are backlight liquid crystal displays, which include a liquid crystal display panel and a backlight module. Usually, the liquid crystal display panel consists of a color filter (CF, Color Filter) substrate, a thin film transistor (TFT, Thin Film Transistor) substrate, a liquid crystal (LC, Liq...
