Abstract

The invention discloses an OLED lighting panel changeable in light color. The OLED lighting panel comprises a first light-emitting region and a second light-emitting region. The first light-emitting region comprises multiple strip-shaped light-emitting regions arranged in parallel, and the second light-emitting region is the same as the first light-emitting region in structure. The second light-emitting region is arranged among the strip-shaped light-emitting regions of the first light-emitting region in an alternate mode. The first light-emitting region and the second light-emitting region are different in emitted light color and share a cathode, and anodes are isolated through isolation pillars to be mutually independent. The OLED lighting panel has the advantages that an OLED lighting component is formed by the utilization of two kinds of mixed light colors, according to different lighting requirements, the finally output lighting light color can be adjusted through adjusting formation of the two kinds of mixed light colors, and then the OLED lighting panel can serve as an ideal indoor lighting product. A light color combination of blue light and orange, or dark blue and yellow, or sky blue and dark red, or white and red, or white and orange is easier to accept by most people, and the OLED lighting panel is suitable for products in volume production.

Description

Technical field [0001] The invention belongs to the technical field of organic light-emitting diode (OLED) lighting / solid-state lighting, and relates to the structural design of a light-emitting unit of an OLED lighting panel, and in particular to an OLED lighting panel with variable light colors. Background technique [0002] OLED lighting belongs to solid state lighting. It has the characteristics of low heat generation, low power consumption, fast response speed, bendability, and impact resistance. At the same time, it has the characteristics of lightness, surface emission, and good ductility. It can be combined with different light colors. The various modules we want can bring new design concepts to the lighting field. With the continuous improvement of the efficiency of OLED materials, high-efficiency OLED lighting modules have been produced, and the current maximum can reach 102lm / W. The application of OLED to the field of lighting has great prospects and is expected to bec...
