Description

Organic light emitting display panel, method of manufacturing the same, and organic light emitting display device

Technical Field

The present disclosure relates to the field of display technologies, and in particular, to an organic light emitting display panel, a method for manufacturing the same, and an organic light emitting display device.

Background

Compared with many Display devices, an Organic Light Emitting Display (OLED for short) has many advantages of being solid-state, self-luminous, wide in viewing angle, wide in color gamut, fast in response speed, high in Light Emitting efficiency, high in brightness, high in contrast, ultra-thin, ultra-Light, low in power consumption, wide in working temperature range, capable of manufacturing large-sized and flexible panels, simple in manufacturing process and the like, can achieve flexible Display in a real sense, and can meet the requirements of people on future displays.

In order to improve the contrast ratio of the display device and achieve the integral black effect, the organic light emitting display device generally employs a Polarizer (POL), which can effectively reduce the reflection intensity of the external ambient light on the screen. However, the light transmittance of POL is generally only about 44%, and more power consumption is required to achieve higher light output. Moreover, the polarizer has large thickness and brittle material, which is not favorable for the development of dynamic bending products.

For this reason, PFS (POL Free Solution) technology with a Color Filter (CF) is generally used in the industry instead of the polarizer. The CF structure generally includes red (R), green (G), and blue (B) color-resisting units and a Black Matrix (BM), and the red (R), green (G), and blue (B) color-resisting units need to correspond to the red, green, and blue pixel units of the OLED device, respectively. By adopting the PFS technology, the thickness of the functional layer is greatly reduced, the light-emitting rate can be improved from 44% to 80%, the light-emitting brightness is greatly increased, and therefore the power consumption of the OLED device is reduced.

At present, the organic light emitting display device is developing to a high screen ratio, and a sea screen, a water drop screen and a full screen technology are produced. To implement a full-screen, it is common in the industry to form blind holes in the display panel to mate with the underscreen camera.

However, in practical applications, it is found that the light transmittance of the blind hole is very low due to the shielding of the color resistance unit, the black matrix and the electrode layer in the OLED product manufactured by the PFS technology, and the requirement of the camera under the screen on the transmittance cannot be met.

[ EXAMPLES one ]

Please refer to fig. 1 to fig. 4, which are schematic structural diagrams of steps of a method for manufacturing an organic light emitting display panel according to a first embodiment of the present invention.

step three, forming a blind hole 10a in the organic light emitting display panel 100, wherein the blind hole 10a penetrates through the first substrate 1, the TFT array layer 5, the organic light emitting layer 5, the thin film encapsulation layer 7, the organic protection layer 6, the color filter layer 4 and the second substrate 2.

Specifically, in the first step, a first substrate 1 is provided, and a TFT array layer 3, an organic light emitting layer 5 and a thin film encapsulation layer 7 are sequentially formed on the first substrate 1 to obtain the array substrate 110. The thin film encapsulation layer 7 covers the organic light emitting layer 5, and can play a role in blocking water and oxygen, so that the OLED device (comprising the TFT array layer 3 and the organic light emitting layer 5) is separated from components such as water vapor and oxygen, and is prevented from being corroded by the water vapor and the oxygen.

In this embodiment, the thin film encapsulation layer 7 is provided with a through hole 7a, and the size and the position of the through hole 7a are set according to the size and the position of the blind hole.

In the second step, a color film substrate 120 is provided, and the color film substrate 120 and the array substrate 110 are aligned and attached to each other to obtain the organic light emitting display panel 100.
