Abstract

The invention provides a display panel supporting column performance evaluation method and device and a display panel. The method comprises the steps of building a test model corresponding to the display panel according to the actual size of the display panel and the position of a supporting column in the display panel, calculating the size variation of the display panel under the action of external force according to the mechanical property of the supporting column and the actual stress of the display panel, and determining the supporting performance of the supporting column according to the size variation. According to the evaluation method, the performance of the display panel supporting column can be efficiently and accurately evaluated, and important data support is provided for design and manufacturing of the display panel and design of the liquid crystal content in the display panel.

Description

technical field [0001] The present application relates to the field of display technology, in particular to a method and device for evaluating the performance of a support column of a display panel, and a display panel. Background technique [0002] A liquid crystal display (LCD) has the advantages of high display quality, high contrast ratio, and good picture effect, and is one of the current mainstream displays. The liquid crystal display panel is composed of upper and lower substrates and liquid crystal arranged between the upper and lower substrates. In order to reserve the accommodation space for the liquid crystal between the two substrates, support columns will be provided on the opposite surfaces of the two substrates; the support performance of the support columns will directly affect the drop rate of the liquid crystal and the yield rate of the liquid crystal display panel. Therefore, in The support performance of the supporting columns needs to be evaluated when ...
