Embodiment 1

[0046] This embodiment provides a method for manufacturing an optical film, the optical film is used to refract light, and the method includes:

[0047] An uneven structure is formed on the surface of the optical film.

[0048] The optical film formed through the above steps has an uneven structure on its surface, which can improve the refraction of light, increase the transmittance and spectral stability of light, and refer to the specific principle figure 2 and Figure 4 As shown, the straight line with the arrow in the figure indicates the optical path. The protrusions and depressions of the uneven structure can change the optical path and increase the refraction effect. When applied to a display device, it can improve the display brightness of the product, reduce power consumption, and increase the viewing angle so that the display product is not affected by the viewing angle.

[0049] It should be noted that the surface of the film mentioned in this embodiment refers t...

Embodiment 2

[0087] Based on the same inventive concept, combining figure 1 and image 3 As shown, this embodiment provides an optical device, including a light-emitting device and an optical film 2 manufactured by the manufacturing method in Embodiment 1. The optical film 2 is used to refract the light emitted by the light-emitting device.

[0088] The above-mentioned optical device can refract light to the light-emitting side through the optical film, and can improve light output efficiency and spectral stability. When applied to a display device, it can also improve the display brightness of the product and reduce power consumption.

[0089] The light-emitting device may be a light-emitting device such as an organic light-emitting diode, a quantum dot light-emitting diode, or the like.

[0090] Taking an organic light emitting diode as an example, the light emitting device includes a light emitting layer 1 , an optical film 2 is closer to the light emitting side of the light emitting d...

Abstract

The invention relates to the field of display technology, and discloses a manufacturing method of an optical film, an optical device, a display substrate and a display device. The optical device includes a light emitting device and an optical film, and the optical film is used to emit light from the light emitting device The light is refracted, and the light is refracted to the light-emitting side, which improves the light output efficiency and spectral stability, improves the display brightness of the product, and reduces power consumption. And through multiple curing and micro-molding processes, an uneven structure is formed on the surface of the optical film, which improves the refraction of light, and can eliminate micro-stress, micro-cracks, micro-peaks and other undesirable phenomena produced by the micro-molding process.

Description

technical field [0001] The invention relates to the field of display technology, in particular to a method for manufacturing an optical film, an optical device, a display substrate and a display device. Background technique [0002] Light-emitting diode (Organic Light-Emitting Device) display devices have the advantages of active light emission, good temperature characteristics, low power consumption, fast response, bendable, ultra-thin and low cost, and have been widely used in display devices. [0003] OLED display devices can be divided into three types according to the direction of light emission: bottom-emitting OLEDs, top-emitting OLEDs and double-sided emitting OLEDs. In bottom-emitting OLEDs, light is emitted from the backplane direction, in top-emitting OLEDs, light is emitted from the top of the device, and in double-emitting OLEDs, light is emitted from both the substrate and the top of the device. [0004] However, due to the influence of the manufacturing proce...
