Epson has announced that it has begun mass-production of a 0.66″ electronic viewfinder LCD display with 1400 x 1050 resolution. A prototype unit was previously shown at the CP+ show in February this year. DPReview quotes Leica as saying that the longevity of LCD is an attraction in this application, compared to OLED, which is used by some makers. On the other hand, this LCD is bigger than a number of others, which might be a challenge for camera designers.
