Embodiment 1

[0037] Such as Figure 1-Figure 3 As shown, Embodiment 1 of the present invention proposes a display panel, including a display substrate 1. The display substrate 1 includes a display area 110 and a non-display area 120 surrounding the display area 110, and further includes:

[0038] The test area 1201, the test area 1201 is set in the non-display area 120, and surrounds the edge of the display area 110, and is used for inkjet printing at the same time as the display area 110; the retaining wall 2, the retaining wall 2 is arranged outside the test area 1201 Edge; sacrificial layer 3, the sacrificial layer 3 is arranged on the test area 1201 and is located in the area surrounded by the retaining wall 2, for forming and separating the printing film layer 4 formed by inkjet printing; wherein, the test area 1201 and the non-display area 120 corresponding to the package area.

[0039] Wherein, the display substrate 1 includes a display area 110 for display, and a non-display area ...

Embodiment 2

[0046] Such as Figure 4-Figure 6 As shown, Embodiment 2 of the present invention proposes a method for manufacturing a display panel, including:

[0047] S1: setting the test area 1201 and the retaining wall 2 surrounding the outer edge of the test area 1201 in the non-display area 120 of the display substrate 1;

[0048] Specifically, during manufacture, a test area 1201 is preset in the non-display area 120 of the display substrate 1, the test area 1201 surrounds the periphery of the display area 110, and the test area 1201 is displayed by setting a retaining wall 2 on the periphery of the test area 1201. range, and can prevent ink droplets from spreading to areas other than the test area 1201 during inkjet printing. The range of the preset test area 1201 is set corresponding to the encapsulation area of ​​the display substrate 1 . When setting, the area of ​​the test area 12011 may not be larger than the encapsulation area of ​​the non-display area 120 . S2: forming a sa...

Embodiment 3

[0061] Embodiment 3 of the present invention provides a display device, including the above-mentioned display panel.

[0062] Specifically, the display device may be an electronic device with a display function such as a television, a mobile phone, and a tablet computer.

[0063] Embodiment 3 of the present invention proposes a display device. By setting a test area, the inkjet printing coverage of the display substrate can be increased, thereby reducing the difference in dryness between the middle part and the edge part of the display area of ​​the display substrate, and solving the problem of the display substrate. The problem of poor uniformity of the printing film layer at the edge of the printing area of ​​the display area can ensure the display effect of the display device; by setting a sacrificial layer in the test area, the sacrificial layer can play a role in the test area after inkjet printing forms a printing film layer. The function of assisting the removal of the ...

Abstract

The invention discloses a display panel, a manufacturing method thereof, and a display device, and relates to the field of display technology, and solves any problems or achieves purposes. The main technical solution of the present invention is: a test area, the test area is set in the non-display area, and surrounds the edge of the display area, and is used for inkjet printing at the same time as the display area; the retaining wall, the The retaining wall is arranged around the outer edge of the test area; the sacrificial layer is arranged on the test area and is located in the area surrounded by the retaining wall, and is used to form and separate the inkjet printing formed Printing a film layer; wherein, the test area corresponds to the encapsulation area of ​​the non-display area.

Description

technical field [0001] The present 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 hailed as a new generation of display technology, and is considered to have broad application prospects due to its advantages such as high responsiveness, high contrast, and flexibility. The inkjet printing technology in the OLED film formation technology is considered to be an important way to realize the mass production of large-size OLEDs due to its high material utilization rate. [0003] In the process of inkjet printing, it is an essential step to remove the solvent through subsequent processes so that the solute dries to form the required film. Due to the difference between the solvent in the sub-pixel structure at the edge of the display area of ​​the substrate and the atmosphere of the intermediate solvent, the solvent at t...
