Embodiment 1

[0021] (1) A high-refractive-index glass substrate (25mm×25mm) is surface-hydrophilized. The glass substrate is immersed in a solution of V (sulfuric acid): V (hydrogen peroxide) = 3: 1 for more than 2 hours, and then cleaned with ultrapure water, V (ultrapure water): V (ammonia water): V (30% hydrogen peroxide )=5:1:1 solution ultrasonically cleaned for 1 hour, cleaned with ultrapure water and stored in ultrapure water for later use.

[0022] (2) A hexagonal lattice of polyethylene spheres with a monolayer diameter of 5 μm was prepared by using polyethylene sphere colloids. The weight ratio of the colloidal polyethylene pellets is 4%. The polyethylene pellets colloid is diluted with a mixed solution of Trion X-100 and methanol (1:400), and the spare glass substrate after the hydrophilization treatment is taken out and placed flat on the On the glue-spinning machine, use the glue-spinning machine to coat the prepared polyethylene spherical colloid solution on the glass substr...

[0027] (1) A high-refractive-index glass substrate (25mm×25mm) is surface-hydrophilized. The glass substrate is immersed in a solution of V (sulfuric acid): V (hydrogen peroxide) = 3: 1 for more than 2 hours, and then cleaned with ultrapure water, V (ultrapure water): V (ammonia water): V (30% hydrogen peroxide )=5:1:1 solution ultrasonically cleaned for 1 hour, cleaned with ultrapure water and stored in ultrapure water for later use. A hexagonal lattice of polyethylene spheres with a single layer diameter of 2.5 μm was prepared by using polyethylene sphere colloids, and the weight ratio of the colloidal polyethylene spheres was 4%. Dilute the polyethylene spherical colloid with a mixed solution of Trion X-100 and methanol (1:400), take out the spare glass substrate after hydrophilization treatment, put it flat on a plastic shaker, and use the glue shaker to remove the prepared glass substrate. A good polyethylene spherical colloid solution is coated on the glass substrate, a...

Abstract

On the glass substrate a large area corpuscle hexagonal array made of monolayer polymers material is formed by using spin coating method and adjusting the ratio of powder size to nonionic surfactant and methanol. The ultraviolet irradiation or direct heating are used to prepare the micro convex lens array layer made of polymers materials. The micro convex lens can be directly used to prepare OLED component.

Description

technical field [0001] The invention relates to a method for manufacturing an organic light emitting diode (Organic Light Emission Diode, OLED) element. It belongs to the technical field of materials and devices. Background technique [0002] Although organic light-emitting diode (OLED) displays have been commercialized in recent years, there is still room for improvement in organic light-emitting diode (OLED) displays, whether in terms of luminous efficiency, service life, switching to amorphous silicon-based large panels, or mass production technology. In addition to household and industrial lighting, the application of next-generation OLEDs is also targeting the white light market with an average brightness of 100lm / W. To achieve this goal, the output light efficiency must exceed 20% when all other parameters are close to their 100% limit. [0003] Organic light-emitting diode (OLED) is a current-mode semiconductor light-emitting device based on ...
