Illuminator capable of improving use life

Abstract

The invention relates to a lighting device, which provides a composite color lighting device which can prolong the service life. One end of organic electric exciting lighting module has a color filter; and a transparent insulating layer is arranged between the organic electric exciting lighting module and the color filter; the transparent insulating layer can be selected from metallic layer or oxide film layer to effectively insulate the outer oxygen or water via the color filter from the tube of organic electric exciting lighting module. The invention can realize composite color lighting device and prolong the service life.

Description

Technical field [0001] The invention relates to a light-emitting device, in particular to a full-color light-emitting device that can increase the service life. Background technique [0002] Organic Light Emitting Device (OLED) has the advantages of self-luminescence, high response speed, light weight, thin thickness, low power consumption, wide viewing angle, high brightness, full color and simple manufacturing process. Therefore, it is widely regarded as the rising star of the display or lighting industry. [0003] In order to achieve the ultimate goal that OLED can be used in white light sources or full-color light-emitting devices, the industry has to seek various technical solutions. At present, the main solutions include the following three: [0004] 1. Three-color light-emitting layer structure: it is mainly a light-emitting device that independently emits organic electroluminescent components of the three primary colors of red (R), green (G), and blue (B) to directly obta...

Problems solved by technology

[0011] Although the hygroscopic layer 159 can remove the moisture and moisture that may remain in the encapsulation layer 157 during manufacture, it cannot effectively bear the moisture or oxygen that enters the organic electroluminescent device from the outside after use, especially through the color filter. light sheet 13 position while entering

Although the silicon dioxide layer 17 in the existing structure also has the effect of blocking external moisture or oxygen from entering the organic light-emitting module 15, the silicon dioxide layer 17 is a fragile and inflexible material, so the organic light-emitting module 15 In the process of combining with the color filter 13, some cracks (not shown) are often formed in the silicon dioxide layer 17 due to improper force, and the cracks will also become external moisture or oxygen passing through the color filter 13 in the future. The position invades the path W1 of the organic light emitting module 15, so that the organic light emitting layer 153 will still be affected by external moisture or oxygen, thereby reducing the working life of the organic light emitting module 15 and the organic electroluminescent device 11.
