Light intensity equalizing element for lighted display panel |
摘要 |
An intensity equalizing element for placement between a number of individual fluorescent tubes in a light panel and the panel image display surface. The element includes a like number of curved surfaces in axial alignment with the individual tubes to reduce variation in observed intensity due to tube spacing. Each curved surface is provided with a non-uniform opaque dot pattern thereon to reduce variation in the intensity of light at the panel display surface and enhance uniformity of light intensity throughout an overlying image display.
