Abstract

The invention discloses an optical fiber back light illumination method of a motion picture, and relates to the technical field of motion pictures. A linear LED lamp strip is used for converting to back light used by two-digit plane frame irradiation through optical fibers to pass through a quantum layer; and the light with one wave length emitted by LED can be converted to light with different wave lengths. The illumination method can reduce the use level of LED beads, can reduce the use area of PCB, reduces the production cost, is wider in color gamut, can adopt the LED beads with one wave length, and is low in production cost and excellent in picture display effect.

Description

technical field [0001] The invention relates to the technical field of LED dynamic pictures, in particular to an optical fiber backlighting method for dynamic pictures. Background technique [0002] Decorative painting is a very common decoration in people's daily life. At present, the decorative paintings on the market are basically static, with neither sound nor animation, and there are very few dynamic decorative paintings. A kind of dynamic painting currently on the market uses electronic ballast fluorescent lamps as the backlight. Rely on the rotation of the motor to pull the shading film, so that the picture forms an effect similar to flowing water. This dynamic picture needs to be provided with motor, and picture frame is often thicker, and needs to be powered with 110V or 220V, therefore, has the disadvantages such as high cost, unattractive appearance, complicated structure, unsafe use. [0003] On September 26, 2007, the State Intellectual Property Office disclos...
