Abstract

The invention discloses an organic light emitting diode panel and an OLED light emitting device. The organic light emitting diode panel comprises: a substrate and a plurality of organic light emittingdiodes, wherein the plurality of organic light emitting diodes are located on the substrate, and a plurality of the organic light emitting diodes are not completely identical in color, first electrodes of the plurality of organic light emitting diodes are configured to bear a same voltage, and second electrodes of the plurality of organic light emitting diodes having a same illuminating color areconfigured to bear a same voltage. Therefore, the organic light emitting diode panel can respectively control the organic light emitting diodes having different light emitting colors to respectivelyemit light, thereby controlling the color of the mixed light emitted by the panel. The panel has at least one of the advantages of simple structure, light weight, flexible illuminating colors, and thelike.

Description

technical field [0001] The present invention relates to the field of illumination and display, in particular, to an organic light emitting diode panel and an OLED light emitting device. Background technique [0002] With the development of OLED technology, organic light-emitting diodes are used in many fields to realize the function of emitting light or displaying. For example, organic light emitting diodes are also applied to prepare various lighting devices. Because organic light-emitting diodes have self-illuminating characteristics, and because organic light-emitting materials can be prepared on flexible substrates, lighting devices based on organic light-emitting diodes have a greater degree of freedom in design, and can form planar rigid, foldable, bendable The light-emitting device can greatly reduce the thickness and weight of the light-emitting device. [0003] Although light-emitting devices based on organic light-emitting diodes have many advantages, current lig...
