OLED display and manufacturing method thereof

Abstract

The invention relates to the technical field of electronic equipment display, in particular to an OLED display screen and a manufacturing method thereof. The method for manufacturing the OLED display screen includes: preparing a display module and a cover glass; processing the cover glass so that the transmittance of the cover glass to visible light is ≤65%; printing: printing a black ink layer on a part of the surface of the cover glass , so that the cover glass forms a visible area and a non-visible area with a black ink layer; bonding: the cover glass is attached above the display module, and the surface of the cover glass printed with the black ink layer is opposite to the display module . The display screen manufactured by the above-mentioned manufacturing method can truly realize the integral black of the display screen, and can take into account the strength of the cover glass.

Description

technical field

[0001] The invention relates to the technical field of electronic equipment display, in particular to an OLED display screen and a manufacturing method thereof. Background technique

[0002] Active-matrix organic light emitting diode (Active-matrix organic light emitting diode, referred to as OLED), is a kind of OLED. Compared with traditional liquid crystal panels, it has the characteristics of self-illumination, fast response, low power consumption, ultra-thin, wide viewing angle, etc. Therefore, OLED displays are more and more widely used in the field of electronic equipment. However, because the OLED display is made of a metal coating in the viewing area, it will reflect metallic luster, causing the OLED display to show different colors when viewed from different angles when the screen is off. For example, when viewed vertically to the surface of the OLED display, the display appears black, and when viewed at an oblique angle (such as 30° to 45°) to the ...

Examples

Embodiment 1

[0039] This embodiment provides an OLED display, such as figure 1 As shown, the OLED display screen includes a display module 1, an optical adhesive 2 and a cover glass 3 arranged in sequence from bottom to top, and the transmittance of the cover glass 3 to visible light is 65%. The optical glue 2 is a full lamination glue, and the optical glue 2 sticks the cover glass 3 on the display module 1 through a full lamination process.

[0040] which, combined with figure 2 As shown, the cover glass 3 includes a visible area 31 located in the middle and a non-visible area 32 located around the periphery. A black ink layer is printed on the lower surface of the non-visible area 32 to form a black frame 4. The cover glass 3 is printed with The lower surface of the black frame 4 is opposite to the display module 1 . The display module 1 of this embodiment may be a display module in the prior art, and the display module 1 may only have a display function, or may have both display and ...

Embodiment 2

[0050] The difference between the present embodiment and the first embodiment is that the light transmittance of the cover glass in the present embodiment to visible light is 55%.

Embodiment 3

[0052] The difference between the present embodiment and the first embodiment is that the light transmittance of the cover glass in the present embodiment to visible light is 50%.
