When it comes to determining the difference between LCD cell phone screens and the newer OLED phone screens there are a few facts that you will need to know.
The main difference between these two types of screens is how they are illuminated.
Liquid Crystal Display (LCD) screens are lit up by a constant light source supplied by LED lights.
Organic light emitting diode (OLED) screens do not have a back light. Each pixel produces its own light individually. Even the brightness of each pixel can be controlled separately per-pixel.
So on OLED screens the whites are brighter and the darks are deeper. The overall contrast is more bold and vibrant. OLED screens are also thinner than LCD screens. This allows for a bigger battery to fit inside your phone, and the larger the battery the longer the life.
But is it really worth the extra $400 you might pay for the higher contrast you’ll get out of an OLED cell phone screen? That would depend on each users own personal preference. Keep in mind that we have been using regular LCD screens all the way up to the iPhone 8 Plus. The iPhone X released in 2017 was the first apple device to come with an OLED display, and if not advertised, few of us would even have noticed the change. So in my opinion having an OLED screen is probably not worth the extra $400 you’ll have to spend on an iPhone XS Max, and the less expensive iPhone XR equipped with that magnificent LCD screen will be more than enough to make you happy.
