Problems solved by technology

In the industry, the resolution of the display is usually improved by changing the arrangement of the sub-pixels of the display. Many patents achieve high resolution by arranging the sub-pixels of the same color together to increase the aperture ratio, such as figure 1 In the pixel arrangement shown, the red light sub-pixels and the green light sub-pixels are respectively arranged together. Since the same sub-pixels of the four adjacent pixels are next to each other, a jagged display effect will be produced when the image is displayed. have a greater impact on visual effects

Embodiment 1

[0030] Such as figure 2 As shown, a high-resolution OLED display device includes an anode layer 5, a light-emitting layer 1, a cathode layer 6 and an encapsulation layer 7. The OLED includes a plurality of pixel units 4, and a There is a display pixel position inversion structure, the display pixel position inversion structure has a double-layer semi-convex lens structure arranged in an array, and one pixel unit in the two adjacent pixel units corresponds to the position of the double-layer convex lens structure set up.

[0031] Specifically, such as figure 2 As shown, the display pixel position inversion structure includes a first transparent film 2 with a first semi-convex lens structure and a second transparent film 3 with a second semi-convex lens structure, and the focal length f of the first semi-convex lens structure is 1 and the focal length f of the second semi-convex lens structure 2 Satisfied: f 2 =9f 1 , the second transparent film 3 is arranged on the side ...

Embodiment 2

[0034] Such as image 3 As shown, the structure of the high-resolution OLED display device in this embodiment is the same as that in Embodiment 1, wherein the display pixel position inversion structure is a layer of transparent film, and the layer of transparent film is provided with a first convex lens structure and a second convex lens structure. Two convex lens structures, the focal length f1 of the first convex lens structure and the focal length f of the second lens structure 2 Satisfied: f 2 =9f 1 , the second lens structure is disposed on a side of the first lens structure away from the organic electroluminescence unit.

Embodiment 3

[0036] The structure of the high-resolution OLED display device in this embodiment is the same as in Embodiment 1, wherein the display pixel position inversion structure is as follows image 3 As shown in , the display pixel position inversion structure includes a first transparent film 2 with a first convex lens structure and a second transparent film 3 with a second convex lens structure, and the focal length f of the first convex lens structure is 1 and the focal length f of the second lens structure 2 Satisfied: f 2 =9f 1 , the second transparent film 3 is arranged on the side of the first transparent film 2 away from the organic electroluminescence unit, and the distance between the second lens structure and the first lens structure is 6f 1 . The distance between the pixel unit and the first convex lens structure is 3f 1 . The focal length f1 of the first convex lens structure is 0.01-5 mm.

Abstract

A high-resolution OLED display device according to the present invention includes an OLED, the OLED includes a plurality of pixel units, and a display pixel position inversion structure is provided in the light emitting direction of the OLED, and the display pixel position The inversion structure has a double-layer convex lens structure arranged in an array, and one pixel unit of the two adjacent pixel units is set corresponding to the position of the double-layer convex lens structure, which adopts a display pixel position inversion structure, so that it can Separate the light rays of pixels that are originally together, effectively reduce the jagged effect, and the preparation process is simple.

Description

technical field [0001] The invention relates to the field of OLED display technology, in particular to an OLED display device with high resolution and a preparation method for the OLED display device with high resolution. Background technique [0002] After nearly 30 years of development, organic electroluminescent devices (English full name Organic Light Emitting Device, referred to as OLED) as the next generation of lighting and display technology, has a wide color gamut, fast response, wide viewing angle, no pollution, high contrast, Advantages such as planarization have been applied to a certain extent in lighting and display. A typical organic electroluminescent device generally includes a transparent substrate, a transparent anode, a cathode, and an organic functional layer arranged between the two electrodes. [0003] Due to factors such as the manufacturing precision of the evaporation mask and the alignment of the evaporation, the AMOLED display has a low aperture ...
