Difference between IPS and AMOLED Screen
We have been getting many questions with regards to mobile display technology the most frequent one being what is the difference between IPS and AMOLED, so we decided we should right an article detailing the pros and cons of both and try to make it as understandable as possible.
IPS (in-plane switching) the technology was made primarily for LCD (liquid crystal display) to overcome the limitations of the regular LCD or TFT-LCD display, the problem with the regular display TFT-LCD was a slow response time, that means a degraded touch response and bad news for gamers as games usually require screens with good response times.
Another thing was a limited viewing angle, you could make out the screen if you’re looking at it straight ahead with a little variation, but move to the side a bit and you wouldn't be able to see the screen, it was great for guys who’d be texting one girl while sitting with another. But now is the age of sharing is caring where you wanna show off what you’re watching, so something had to be done.
IPS was the answer allowing for better response times meaning good touch response and better gaming. Also it allowed for a better viewing angle meaning you could watch the screen while having others watch it too.
• Better response time as compared to regular LCD's.
• Better Color reproduction.
• Better viewing angle.
• Sharper Images.
• Requires a stronger backlight.
• More power hungry.
• Screens (cell phones) are usually much more thicker (bulkier) due to back-light source.
AMOLED or (Active Matrix Organic Light Emitting Diode) is an upgrade to OLED, this tech basically consists of organic compounds which when are introduced to an electric charge produce luminosity or light.
AMOLED was the tech that allowed for smart-phones to become even sleeker, basically since it does not require any back-light as compared to its IPS counterpart it is less bulky. At the same time it provided better viewing angles and better contrast as compared to the simple LCD. The main factor that really set apart the AMOLED was its power consumption, it uses less battery power as compared to the IPS tech or regular LCD's.
• No Back-Light Required.
• Screen is slimmer, less bulky phone.
• No back-light, less battery usage, greater battery life.
• Great Contrast.
• Difficult to produce, more expensive tech.
• Images Not as sharp IPS.
• Less Bright as compared to IPS, so less daylight visibility.
• Display Colors Degrade over time.
