![]() ![]() ![]() We exported the spectral power distribution (SPD) charts for all OLED TVs involved in this test, and we fully disassembled the LG A1 OLED, the LG G1 OLED, and the Sony A80J OLED. We know that LG Display makes the OLED panels for both LG Electronics and Sony OLED TVs, but what about the other components? We decided to build a database of the different TVs and look into the specific panels used to look for any patterns. ![]() To understand the difference between LG and Sony, we first wanted to determine how much these TVs have in common. We found there's no difference between LG and Sony TVs in this regard-they both couldn't keep up, and the temperature increased dramatically due to the lack of ABL. Although this procedure was only run on the Sony OLEDs with image retention, we also ran the recovery video on an LG OLED to see if their temperature increased due to the fast-changing pattern. This led to a fairly significant temperature increase on all TVs, so we had to reduce the display brightness to avoid causing permanent damage. In our attempts to clear up any image retention on these TVs, we encountered an issue very early on in that the TVs were running at full brightness, and ABL wouldn't kick in with such a rapidly changing pattern. This video quickly alternates between different colored images. We decided to run a pixel refresh video to stimulate the OLED pixels and hopefully clear any image retention. The first step here was to determine if this was permanent burn-in or just severe image retention, as we encountered during the two-week soft launch of our test in October 2022. The Sony A8H, A80K, A80J, A90J, and A90K all showed severe signs of image retention. LG C2 OLED - 50% slide showing no image retention after two monthsĪfter taking our two-month photos and measurements, we were surprised to see what looked like severe image retention on some of our WOLED displays. ![]()
