Problems solved by technology

Specifically, in the terminal area, the surface test will be carried out on the exposed area of ​​the display device. The test method is to draw a line with a dyne stroke. If the dyne line shrinks, it proves that the surface material in this area has changed, which will affect the overall effect.
However, since the display panel is provided with a cushioning component, after the cushioning component contacts the ink layer, the material in the cushioning component will chemically react with the ink layer, which will affect the performance of the ink layer, and the contaminated ink layer will interact with other films When the layers are bonded, problems such as loose bonding and tearing are prone to occur, which will cause errors in the dyne value and lead to problems such as poor sealing of the display panel
[0004] To sum up, when testing the performance of the display device, the cushioning components installed inside the display device are likely to react with the ink layer, thereby affecting the performance of the ink layer, resulting in poor adhesion between the ink layer and other film layers and It is easy to tear and other problems, which will eventually lead to the inability to obtain accurate dyne values, which will affect the performance and quality of the display panel

Abstract

The invention provides a display device which comprises a cover plate, a display panel and a supporting component, the cover plate comprises a light shielding layer and a blocking component, one end of the supporting component is connected with the display panel, the other end of the supporting component is connected with the light shielding layer of the cover plate, the blocking component divides the light shielding layer into a dyne value testing area and a non-testing area, the two areas are not communicated, so that the film layers in the dyne value testing area have good performance, the bonding performance between the film layers is improved, the accuracy of the display panel during dyne value testing and the sealing performance of the display panel are ensured, and the quality of the display panel is effectively improved.

Description

[0001] The invention relates to the field of display panel manufacturing, in particular to a display device. Background technique [0002] With the continuous improvement of display panel manufacturing technology, people also put forward higher requirements on the quality and performance of the display panel. [0003] In order to obtain a display device with higher performance, multiple tests need to be performed on various properties of the display panel during the preparation process of the panel, so as to ensure that the display device has higher reliability and higher display performance. During the manufacturing process of the display panel, a layer of ink or the like is often provided at the bottom edge area of ​​the panel to prevent external light from entering the panel. At the same time, a buffer layer is provided between the cover plate and the panel to prevent the display device from collapsing when dropped or under pressure. During the testing process, the quality...
