Abstract
The invention discloses an OLED light source capable of being optionally cut and a cutting method thereof. The OLED light source comprises an organic layer, wherein a first electrode layer and a first buffer layer are sequentially arranged on the organic layer; a second electrode layer, a second buffer layer and a conducting base plate are sequentially arranged below the organic layer; at least two first through holes are formed in the first buffer layer; a first electrode lead penetrates through the through holes; the first electrode lead is connected with the first electrode layer; a second electrode lead is connected with the lower part of the conducting base plate. When the second buffer layer is made of non-conductor materials, at least two second through holes are formed in the second buffer layer, and the second buffer layer is deposited in the second through holes. The OLED light source is cut into light-emitting surface bodies with arbitrary shapes through laser, the only thing to do is to ensure that the cut OLED light source comprises at least two first through holes and / or second through holes, and further different demands of users are met.
Description
technical field [0001] The invention relates to an OLED light source, in particular to an OLED light source that can be cut at will and a cutting method thereof. Background technique [0002] At present, OLED materials are gradually entering the lighting market, and OLED materials have attracted more users due to their lightness, thinness, and softness. The OLED light source is mainly based on glass substrates, and the shape is mostly rectangular or square. The application field can only be determined according to the shape of the OLED light source, which has great limitations. Existing OLED lighting uses glass substrates, leading the positive and negative lead wires to the edge of the glass, and then connecting to the positive and negative electrodes of the power supply through flexible cables, etc., and then emitting light after conduction. Since the cutting shape of the glass is relatively simple, it is difficult to realize a special-shaped lighting source, and at the sa...
