Problems solved by technology
However, during the manufacturing process of the display panel, there will be local bubbles. There may be many factors for the generation of such bubbles, and they will often be produced after the factory inspection. Rework or scrap will seriously increase the production cost and the high defect rate will affect the customer's evaluation
[0003] Regarding the causes of bubbles, one of them is the gas precipitation inside the RGB color-resist layer. The main material of the RGB color-resist layer is organic matter. In the prior art, when the RGB color-resist layer is made, there may be gas remaining inside it.
At the same time, due to the characteristics of organic matter, under certain conditions, such as a high temperature environment, small molecular carbon oxide gases, such as CO, CO2, etc., will be slowly released inside the RGB color resist layer, and these small molecular gases will form bubbles locally. , will affect the display effect and reduce the product yield
[0004] At present, there is no good detection method for the gas-evolution-type bubbles inside the RGB color-resistive layer during the production process, resulting in unstable product quality, which urgently needs to be solved.

Abstract
The invention provides a detection method of a display panel, comprising the steps of: making a via hole, standing to observe bubbles, preliminary judging the risk of bubbles, placing in a constant temperature environment, and confirming and judging the risk of bubbles. Through this detection method, it is possible to detect the gas-evolution-type bubbles that may exist in the color-resistive layer of the display panel, so that the production line processing can be fed back in time and the gas generated in it can be released, thereby avoiding the formation of air bubbles in later products due to the gas evolution inside. The risk of air bubbles improves the product qualification rate.
Description
technical field [0001] The invention relates to the field of display technology, in particular to a detection method of a display panel. Background technique [0002] Liquid Crystal Display (LCD for short) products have become the mainstream of today's displays due to their advantages of thinness, environmental protection, high performance, and diverse size options. However, during the manufacturing process of the display panel, there will be local bubbles. There may be many factors for the generation of such bubbles, and they will often be produced after the factory inspection. Rework or scrap will seriously increase the production cost and the high defect rate will affect the customer's evaluation. [0003] Regarding the causes of bubbles, one of them is the gas precipitation inside the RGB color-resist layer. The main material of the RGB color-resist layer is organic matter. In the prior art, when the RGB color-resist layer is made, there may be gas remaining inside it. ...
