Organic light-emitting diode (OLED) lighting device

Abstract

The invention discloses an organic light-emitting diode (OLED) lighting device, which comprises a conductive substrate and a packaging film. An OLED component is arranged between the conductive substrate and the packaging film. Auxiliary electrodes are led out from the OLED component. The packaging film is provided with openings at positions corresponding to the auxiliary electrodes, and a probe is arranged in the opening, wherein one end of the probe is electrically connected with one auxiliary electrode, and the other end is electrically connected with a conductive backplate. According to the invention, openings are provided in the packaging film, and the auxiliary electrode and a conductive circuit are connected through the probe, thereby being capable of reducing places occupied by a packaging precision area and a packaging bonding area. In addition, the auxiliary electrode of two adjacent components can be shared, thereby further reducing the proportion taken up by a non-luminous area. The OLED lighting device needs not to cut the substrate, thereby reducing the loss caused by glass cutting, and improving the utilization rate of the substrate. The blank space in assembling a screen body is reduced, and the on-off, the illumination and the color of products can be controlled through the conductive backplate.

Description

technical field [0001] The present invention relates to organic light-emitting diode (Organic Light-Emitting Diode, OLED) technology, in particular, a device for realizing lighting by using OLED. Background technique [0002] OLED applications have the advantages of lightness, thinness, uniform light source distribution, flexibility, and colorfulness in lighting, breaking the impression that traditional lighting and LED lighting are bulky, stiff, and heavy (when LEDs are added with heat dissipation modules). Using OLED lighting can realize a real surface light source. Using OLED can realize large-area lighting, so that the entire ceiling or wall emits soft light, unlike bulbs, fluorescent lamps, etc., which are partial lighting, making the light source feel more gentle. Comfortable.

AI Technical Summary

Problems solved by technology

[0003] In the prior art, the OLED lighting screen needs to lead out auxiliary electrodes on at least one side of the screen, and there are also two non-luminous areas, the packaging precision area and the packaging bonding area, between the auxiliary electrodes and the light-emitting area of ​​the screen. Due to the limitations of existing technology, the minimum non-luminous area including the auxiliary electrode is 2~3mm, which directly affects the aesthetics of OLED lighting in appearance and overall design

Especially in the application of the lighting wall, when the OLED lighting screens of the prior art are used for splicing, there will be obvious non-luminous areas between the screens, which will affect the vision and overall aesthetics of the lighting.
