However, we can't confidently say one TV will have better uniformity than another just because of the backlight or panel type.Įarly OLEDs had issues when displaying 5% gray images. LED TVs can suffer more from uniformity issues, especially if their backlight is edge-lit and not direct LED. For the most part, OLEDs tend to have better uniformity, and there are rarely any issues. As such, they perform differently when it comes to uniformity. While LED TVs are really LCD TVs backlit by LED backlights, OLEDs don't have any backlighting and instead turn each pixel on and off. LED and OLED TVs use different technologies to display an image. Higher-end LED-backlit TVs tend to use either Mini LED or direct LED backlighting, generally better for uniformity than edge-lit TVs. Generally, though, higher-end TVs should have better gray uniformity, as the manufacturers will have stricter standards for the panels used. This means that no two TVs, even of the same model, will have matching uniformity. Gray uniformity is unique to each individual panel. With OLED TVs, the gray uniformity issues are more related to imperfections in the panel itself, independent of pressure-related problems. Size may also have an effect because it's harder to keep a larger screen uniform, but since we only test one size of each TV, we can't draw any conclusions about this. Also, too much pressure can affect the backlight and how much light it diffuses, which causes some areas to be darker. LCD panels are pretty sensitive to pressure, so extra pressure caused by misalignment of the TV's components or by mishandling of the panel during manufacturing or shipping could lead to defects appearing. With LED-backlit LCD TVs, gray uniformity issues are caused by a couple of factors. Additional Information Causes of gray uniformity issues
