The future outlook of AMOLED TV/OLEDTV

In order to impact the TV market, AMOLED TVs must be competitively priced with identically sized AMLCD and PDP TVs. In addition, certain milestones must be achieved, such as 40.000 hours of lifetime, a color gamut exceeding 80% of the NTSC standard, a peak luminance higher than 400 nits, a darkroom contrast ratio higher than 5000:1, and no image burn-in after a least 10 days of continous operation.

This issues that must be resolved include the attainment of a TFT threshold-voltage change of less than 0,2 V for the lifetime of the display, the elimination of fine mura, and a brightness uniformity of more than 80%.

To be cost-competitive, AMOLEDS must maintain a production yield comparable to that of AMLCDs, and the TFT backplane should be produced by using a process consisting of four or five photo-masking steps.

With the current pace of innovation and technological development, we anticipate that large-sized AMOLED Tvs will enter the market in about 2-4 years and dominate the TV market in the near future.
