Embodiment 1

[0039] This embodiment provides an area multicolor OLED, such as figure 2 As shown, the area multi-color OLED includes a substrate 10 , a back cover 20 and an encapsulant 30 .

[0040] The upper surface of the substrate 10 has a matrix of pixel display areas 100 of the same color, and the lower surface is formed with filters 101 of more than two color areas. Such as image 3 As shown, the pixel display area matrix 100 includes, from bottom to top, an anode 1001, a hole injection layer 1002, a hole transport layer 1003, a light emitting layer 1004 of the same color, an electron transport layer 1005, an electron injection layer 1006 and a cathode 1007. In the present invention, the organic materials of the light-emitting layer 1004 are the same, so there is no need to perform multiple alignments during the manufacturing process, and a single-color OLED can be produced first, which simplifies the process flow, improves production efficiency, and does not require complicated des...

Embodiment 2

[0053] This embodiment provides a method for manufacturing an area multicolor OLED, such as Figure 7 shown, including:

[0054] S10, providing a substrate and a back cover; the upper surface of the substrate has a matrix of pixel display areas of the same color, and the back cover has a light emitting area corresponding to the matrix of pixel display areas.

[0055] The method for manufacturing an area multi-color OLED in this embodiment is different from depositing different organic functional layers on pixel unit positions corresponding to different colors in the prior art, but depositing the same organic functional layer on all pixel units, that is, all pixel units It emits light of the same color.

[0056] The formation process of the pixel display area matrix of the same color on the upper surface of the substrate may specifically include: sequentially depositing and forming an anode, a hole injection layer, a hole transport layer, a light emitting layer of the same col...

Abstract

The invention discloses an organic electroluminescent display with multicolor regions and a method for manufacturing the same. The organic electroluminescent display with multicolor regions comprises a substrate, a rear cover and a packaging adhesive, wherein the upper surface of the substrate is provided with a pixel display region matrix of the same color, while the lower surface is provided with a light filter with more than two colored regions; one surface of the rear cover facing the substrate is provided with a light emitting region corresponding to the pixel display region matrix; and the packaging adhesive is positioned on the contact surfaces of the substrate and the rear cover and surrounds the light emitting region and the pixel display region matrix. By adopting a light emitting layer of the same material in the organic functional layer of an organic light-emitting diode (OLED) and forming the light filter at a set region on the lower surface of the substrate, the transition zone of the light filter at the adjacent place can be controlled to be very narrow so as to realize continuous display of patterns.

Description

technical field [0001] The invention relates to the technical field of electronic appliances, in particular to an area multicolor organic electroluminescence display and a manufacturing method thereof. Background technique [0002] Organic light-emitting display (OLED, Organic Light-Emitting Diode) is an emerging flat-panel display at present, because OLED has active light emission, high contrast, can be thinned, fast response, no viewing angle limit, wide operating temperature range, low With many advantages such as power consumption, strong shock resistance and flexible display, it is recognized as the main force of the next generation of displays. [0003] The typical structure of OLED is as figure 1 As shown, it includes: a substrate glass 1, a rear cover 6 corresponding to the substrate glass 1, a desiccant 5 attached to the light-emitting area on the side of the rear cover 6 facing the cathode 4, and a contact position between the glass substrate 1 and the rear cover ...
