— A new method for achieving full‐color capability for inorganic EL displays was developed, which combines electroluminescence with photoluminescence phenomena in the same device structure. In this display panel, the blue emission was obtained from the EL device by using the Eu‐doped barium thioaluminate phosphor material system, which was then used to generate green and red emission by the use of down‐conversion materials. The major advantages of the Color‐by‐Blue method (CBB) are the elimination of color‐balance control issues associated with the use of different electroluminescent phosphor materials for red, green, and blue with potentially different threshold voltages for the onset of luminance and the achievement of a low‐cost high‐yield manufacturing process.
