Problems solved by technology
[0003] However, due to the design of the above-mentioned inclined inkjet head, the number of nozzles used by the inkjet head is different each time the ink is dropped, which often causes the problem of inconsistent ink droplet capacity of the nozzles and makes the pixels Poor molding quality, which in turn affects the performance of organic light-emitting display panels in image color display

Embodiment Construction
[0021] see figure 1 , which is a schematic diagram of an organic light emitting display panel 10 proposed according to an embodiment of the present invention. The organic light emitting display panel 10 uses a plurality of inkjet heads 12 (in figure 1 It is prepared by spraying organic light-emitting ink, which is only shown in a simple way. figure 1 It can be seen that each inkjet head 12 has nozzles 13 arranged at intervals for printing droplets of organic light-emitting ink, and the organic light-emitting display panel 10 includes a substrate 14, a plurality of barrier arrays 16, and a plurality of organic light-emitting pixels 18 , wherein the substrate 14 can be a common substrate (such as a glass substrate, a transparent plastic substrate, etc.) that is commonly used in organic light-emitting display panels and has a boundary 15, while the inkjet head 12 forms an oblique angle with the boundary 15 of the substrate 14 θ, the inclination angle θ may be greater than 0° and...

A method for manufacturing an organic light-emitting display panel and an organic light-emitting display panel. The organic light-emitting display panel comprises a substrate, and the method comprises the steps of: forming a plurality of retaining wall arrays having a plurality of retaining walls on the substrate, enabling a plurality of ink jet heads respectively having a plurality of jet nozzles which are in spaced arrangement to move relative to the substrate along an advancing direction perpendicular to a boundary of the substrate, and enabling at least one jet nozzle in the plurality of jet nozzles to jet organic light-emitting ink and forming at least one organic light-emitting pixel within the at least one retaining wall. A tilt angle is sandwiched between an arrangement direction of the plurality of retaining walls and the boundary of the substrate, and the tilt angle is sandwiched between the each ink jet head and the boundary of the substrate. The present invention can ensure that the organic light-emitting pixel has good forming quality, thereby raising performance of the organic light-emitting display panel on image color display.
Description
technical field [0001] The present invention relates to a method for manufacturing an organic light emitting display panel and the organic light emitting display panel thereof, in particular to a method for manufacturing the organic light emitting display panel by using an inkjet head and the organic light emitting display panel thereof. Background technique [0002] With the advancement of inkjet printing technology and display technology, inkjet printing is used to spray organic light-emitting ink into pixel barriers to form pixels on a substrate, which has been widely used in the process of organic light-emitting display panels. Generally speaking, since the distance between adjacent nozzles on the inkjet head is not equal to the distance between adjacent pixels, the inkjet head will only use part of the nozzles corresponding to the pixels to spray droplets during the process of printing and forming pixels. Therefore, in practice, the organic light-emitting display panel ...
