DisplaySearch has put together a new report on the Sony XEL-1 OLED display, detailing the devices unique characteristics but confirming video lifetime of about half (~17,000 hours) of Sony's official estimates.
DisplaySearch's OLED Characterization Report: Sony XEL-1, includes a description of the sub-pixel architecture, micro cavity, the compensation circuits and the top emission OLED device, and includes measurements of lifetime by color and image, power consumption differential aging, burn-in, contrast ratio and luminance.
Other key findings in the report include:
- The sub-pixel architecture includes two TFTs and two capacitors.
- The pixel architecture does not use a common support layer, as the materials and thickness are different.
- The microcavity structure results in multiple reflection interference.
- The brightness is severely reduced in high ambient conditions.
- The black levels are less than 0.01 cd/m², lower than any other display (PDP or LCD) currently on the market.
- The top emission design includes a color filter and a circular polarizer.
- The cathode is semi transparent.
- The design includes a unique approach to cooling the OLED.
- The results demonstrate that the Sony display is significantly inferior in many ways to the current AMOLED designs. Consumers who are amazed by their first experience with OLED TVs can only expect significantly improved performance in the future.
