Problems solved by technology

However, the following problems exist in the current packaging process: when the glass glue enters and fills the filling hole 51' after being softened at high temperature, the expansion coefficient of the glass glue is larger than that of the contacting material. Therefore, the glass glue filling part 5 The local area of ​​'will be affected by the expansion force of the glass glue and some external forces (for example, the downforce of the module cutting, the force of the separation paddle action, and the force of the chassis when the panel is subjected to shock and impact, etc.) It is damaged and cracks are formed, and then the external water and oxygen can invade the display panel from the cracks and come into contact with the display element 3', and the display element 3' that is in contact with the water and oxygen may not be able to emit light normally during use
Therefore, the display panel usually suffers from pixel shrinkage at the part of the crack.

[0034] See image 3 , which shows a schematic cross-sectional structure diagram of the display panel according to the first embodiment of the present invention. Such as image 3 As shown, in the preferred embodiment of the present invention, the display panel includes: a first substrate 1 , a second substrate 2 , a display element 3 and a package 4 . In an embodiment of the present invention, the first substrate 1 is an array substrate. The second substrate 2 is disposed opposite to the first substrate 1 , and the second substrate 2 is a package cover. The display element 3 is arranged on the first substrate 1 and is located between the first substrate 1 and the second substrate 2 to form a light-emitting area of ​​the display panel, wherein the display element 3 can be any structure in the prior art, for example, The display element 3 may include an anode, a light-emitting layer disposed on the anode, and a cathode disposed on the light-emitting layer, which will not be de...

[0046] See Figure 9 , which shows a partially enlarged view of the package area of ​​the first substrate according to the second embodiment of the present invention. Similar to the above-mentioned first embodiment, in this embodiment, the encapsulation area 11 includes a groove portion surrounding the display element. The groove portion includes a first extension portion 61 ″ disposed along a first direction and a second extension portion 62 ″ disposed along a second direction, and the first extension portion 61 ″ communicates with the second extension portion 62 ″.

[0047] with the above Figure 4 and Figure 5 The first embodiment shown differs in that the encapsulation region 11 comprises only one recessed portion. The groove portion includes a plurality of first extensions 61 ″ and a plurality of second extensions 62 ″. Specifically, in Figure 9 In the illustrated embodiment, the first direction and the second direction are preferably perpendicular to each other, b...

[0049] See Figure 10 , which shows a partially enlarged view of the package area of ​​the first substrate according to the third embodiment of the present invention. with the above Figure 5 The first embodiment shown differs in that the encapsulation region 11 comprises only one recessed portion. The groove portion further includes a plurality of third extensions 63 extending along the third direction, and each third extension 63 communicates with the first extension 61 . Specifically, in Figure 10 In the illustrated embodiment, the groove portion is in the shape of a fishbone, the third extension portion 63 and the second extension portion 62 are symmetrical along the first extension portion 61 , and neither the third extension portion 63 nor the second extension portion 62 is aligned with the second extension portion 62 . The first extension 61 is vertical. This embodiment can also be implemented, and has similar effects to those of the above-mentioned first embodimen...

Abstract

The invention discloses a display panel and a display device. The display panel comprises the components of a first substrate, a second substrate which faces the first substrate; a display element which is arranged on the first substrate and is arranged between the first substrate and the second substrate; and a packaging member which is arranged between the first substrate and the second substrate and surrounds the display element, wherein the first substrate comprises a packaging area which corresponds with the position of the packaging member. The packaging area comprises a groove part which surrounds the display element. The groove part at least comprises a first extending part which is arranged in the first direction, and a second extending part that is arranged in a second direction. The first extending part is communicated with the second extending part. One end of the packaging member is inserted into the groove part.

Description

technical field [0001] The present invention relates to the field of display technology, in particular to a display panel and a display device with the display panel. Background technique [0002] Compared with many display panels, OLED display panels have many advantages such as active light emission, high contrast ratio, and no viewing angle limitation. OLED display panels are not only lighter and thinner in size, but also lower in power consumption than the original devices, which helps to improve the endurance of equipment. Therefore, OLED display panels have been widely used in the field of display technology and will become the mainstay of display consumption in the future. mainstream. However, the lifetime of the OLED display elements in the OLED display panel is an important bottleneck in its development. The light-emitting organic material of the OLED display element will be damaged by the intrusion of water and oxygen, causing the pixels in this area to fail to l...
