Display panel, manufacturing method thereof, and display device

Abstract

The invention discloses a display panel, a preparation method thereof, and a display device. The display panel includes a mounting hole and a packaging area surrounding the mounting hole, the packaging area includes a base substrate, an isolation structure disposed on the base substrate, the isolation structure includes an isolation column and behind the isolation column A gentle layer formed and located on both sides of the isolation column, the gentle layer includes a filling part in contact with the sidewall of the isolation column, and the surface of the filling part on the side facing away from the base substrate is far away from the isolation column. The post position gradually moves away from the base substrate toward the direction closer to the spacer post position. The display panel eliminates the sharp surface at the bottom of the side wall of the isolation column, making the bottom surface of the side wall of the isolation column more gentle, thereby making the film thickness of the inorganic packaging layer more uniform, avoiding packaging failure, ensuring the packaging effect, and ensuring The life of the OLED in the display area is greatly reduced.

Description

technical field [0001] The invention relates to the field of display technology, in particular to a display panel, a manufacturing method thereof, and a display device. Background technique [0002] Organic Light Emitting Diode (OLED) is an active light-emitting display device, which has the advantages of self-illumination, wide viewing angle, high contrast, low power consumption, and fast response. With the continuous development of display technology, OLED technology is increasingly used in various display devices, especially smart terminal products such as mobile phones and tablet computers. [0003] With the development of active matrix organic light-emitting diode (Active Matrix Organic Light-EmittintgDiode, AMOLED) technology, the requirements for the display area of ​​display devices are getting higher and higher, such as full screen and borderless screen, in order to bring users more Dazzling visual impact. Since products such as smart terminals usually need to be ...

AI Technical Summary

Problems solved by technology

[0005] In the existing technology, such as figure 1 as shown, figure 1 It is a schematic diagram of the packaging area of ​​a display panel. Since the angle θ of the foot of the isolation column in the inverted trapezoidal structure is small, the thickness of the inorganic packaging layer at the foot of the isolation column is relatively thin, so that the inorganic packaging layer is easy to be placed at the bottom of the isolation column. The position of the pin is damaged, causing the package to fail, making water and oxygen invade into the OLED through the isolation column, which affects the life of the OLED
