Recently, the report "Portable Display Equipment and Television (OLED&LCD) Film Quality/Visual Comfort Subjective Evaluation and Related Optical Performance Evaluation" led by Saixi Laboratory of China Electronics Technology Standardization Institute was released. This test focuses on the optical performance of display devices, subjective image quality experience and visual comfort and other dimensions related to user viewing experience, and conducts a lateral comparison test on portable display devices (such as mobile phones), OLED TVs and LCD TVs, thus drawing a series of subjective conclusions.
First, mobile phone and TV comparison test (6.1 inch > 65 inch OLED screen)
Test conclusion: Compared with TV and mobile phone, TV has an advantage in objective indicator testing. In terms of subjective picture quality evaluation, due to the large field of view of the TV, it is superior to the mobile phone in the items of immersion, presence and vividness, and has obvious advantages. At the same time, in terms of comfort evaluation, the overall score of the mobile phone is inferior to the TV due to the small screen and the viewing distance, and the TV scoring advantage is obvious in the comfort description options (eye pain, eyelid heaviness, dry eyes, glare and fatigue).
Second, TV screen comparison test (65 inch OLED & LCD screen)
Test conclusion: Compared with OLED TV and QD-LCD TV, OLED TV has advantages in objective index testing. It also has obvious advantages in all projects of subjective image quality evaluation. At the same time, in terms of comfort evaluation, OLED TVs have obvious advantages in scoring all options for visual comfort (eye pain, heavy eyes, dry eyes, glare and fatigue) due to their moderate brightness.
In all conclusions, we particularly note that in the comparative test of OLED TV and QD-LCD TV, OLED TV performed better than the compared product in almost all tests and subjective evaluation items. It should be noted that the comparison test of OLED TV and QD-LCD TV is done in movie mode, so it can be understood that OLED TV has a more ideal experience in the movie viewing scene.
· OLED and comparison of evaluation results with QD-LCD TVs
Evaluation results of optical characteristics
In the optical characteristics evaluation link, the contrast, color gamut and viewing angle of OLED TV are higher than those of QD-LCD TV, and the blu-ray output of OLED TV is smaller than that of QD-LCD TV, which causes visual fatigue in terms of glare performance, OLED TV has less impact on the naked eye.
Picture quality evaluation results
According to the evaluation results of the picture quality evaluation in the movie mode, the "naturalness", "contrast", "brightness" and "overall preference" of the OLED TV screen are better than the QD-LCD TV tested.
Visual comfort evaluation results
Visual comfort is to express the level of visual fatigue that slows down the viewing display equipment printing, and it can be seen from the results that OLED TV is better than the QD-LCD products in the subjective evaluation results such as "eye pain", "heavy eyelids", "dry eyes", "glare", "eye fatigue", etc., which can be intuitively understood as OLED is a more effective TV category to reduce visual fatigue.
OLED TV with self-luminous physical characteristics, in the color brilliance, darkfield detail performance, etc., relative to the traditional LCD TV has a high-end reputation visible to the naked eye, and because the physical structure is simpler, so that OLED TV often has a thin and elegant shape, relying on these two pedigree advantages to gain a large number of consumer recognition, LG Display (the world's only TV with large-size OLED panel suppliers) adhere to the deep optimization of OLED TV display performance and comfort indicators, Through this test, we can see that OLED TVs not only continue to lead in picture quality, but also have achieved gratifying results in low blue light, no glare, and reduced visual fatigue.
