I started pc gaming with a secondhand launch day lcd steam deck. Then my wonderful boyfriend bought me the 1tb oled white steam deck. For starters, the display is much more vivid. Lines look sharper, colors are more vibrant, and screen refresh rate is faster. For some people, that may not be a big deal, but I appreciate the benefits so much that I won’t buy another $400+ handheld unless it has an oled screen
The best way to take a difference is to turn your LCD screen on and fullscreen a black image. That is what black looks like on an LCD, and it usually looks fine when compared to every other color on an LCD Screen. Now turn the screen off. That is what black looks like on an OLED. The next most notable difference is bloom. Place white text on a black background and you will see the background near the text is a brighter color than other black areas. OLED solves this too.
OLED’s main downsides are A: Price, and B: Brightness, oleds typically cant get as bright as LCD’s or Mini-LED. They also typically have worse text readability, since text has been designed around a very particular subpixel layout that oled doesnt use. The upside is Better blacks, better contrast, and faster response times (the time it takes for a pixel to change from one color to another is extremely small.) Burn in is not really a problem on modern oleds, at least under normal use
Oled is not without competition, there is W-Oled for example which adds a white sub pixel (WRGB) to improve screen brightness, but at the cost of more “chromatic abberation-like” effects around text, and there is also mini-LED, which is notably brighter than oled, and with better blacks than lcd, although not quite as black as oled. Mini-led and oled are very close competitors in terms of overall quality right now.
