Samsung Electronics announced on Jan. 1 that all of its 2020 QLED 8K TV models have obtained 8K UHD certification from the Consumer Technology Association (CTA) of the United States. As a result, the dispute between Samsung Electronics and LG Electronics over 8K TV image quality and certification is expected to end.
The CTA is the organizer of Consumer Electronics Show (CES), the world’s largest consumer electronics and information technology (IT) exhibition. It announced the criteria for certification of 8K TVs in September 2019, including the requirement that the contrast modulation (CM) should exceed 50 percent. Samsung Electronics’ 2020 models can carry the CTA 8K UHD certification logo, by meeting all CTA certification standards, including the CM value.
Earlier, LG Electronics raised the 8K picture quality debate by taking issue with the low CM value of Samsung Electronics' 8K TVs at IFA 2019 in September last year. "The CM for LG Nano Cell 8K TVs is 90 percent while that of Samsung QLED 8K TVs is a mere 12 percent," said Park Hyung-se, vice president of LG Electronics at the time. "Samsung TVs are 8K in number of pixels, but not 8K in terms of resolution."
Samsung Electronics responded at the time by noting that CM is not a decisive criterion for judging 8K technology as it is a concept introduced in 1927. It also pointed out that the International Committee for Display Metrology (ICDM) said in 2016 that CM is an incomplete criterion for latest displays. In addition, Samsung claimed that it is not technically difficult to raise the CM value above 50 percent.
"It is very fortunate that Samsung Electronics has decided to comply with international standards and meet the CM standard for 8K TVs," LG Electronics said.
