Today, we have computers, Tablets There are two main types of displays, especially those used in smart phones. There are two display technologies: AMOLED Display: Active Matrix Organic Light Emitting Diode (IPS LCD Display) and In-Plane Switching Liquid Crystal Display (IPS LCD Display).
This article will focus on the two most commonly used AMOLED Display and IPS LCD Display technologies used in SmartPhones. How they work; Advantages Weaknesses Other variants of AMOLED Display: OLED, Samsung’s Super AMOLED, Dynamic AMOLED, IPS LCD Display, Original LCD, TFT LCD and Apple’s Retina LCD Display.
Working Technology: How do these two displays work?
The IPS LCD Display, also known as the In Plane Switching Liquid Crystal Display, is derived from the old LCD technology used in computers and mobile phones in the past. The way an LCD display works is that you need a backlight to illuminate the pixels on the screen.
Apple Retina LCD Display
Apple’s Retina LCD Display was introduced with the iPhone 4 and is still in use today until the iPhone 11. It uses standard LCD technology and is an LCD display that incorporates Apple’s Retina technology. Retina technology is a technology that fills in the gaps between pixels on a screen. It is made up of innumerable eyes and pixels. It is actually based on LCD technology.
An AMOLED display, called an Active Matrix Organic Light Emitting Diode, uses only organic materials, without the need for a backlight, to display pixels on the screen. An AMOLED display with a pixel display; There are two layers: the Touch Layer for SmartPhones.
Super AMOLED, Dynamic AMOLED etc,
Samsung’s latest Super AMOLED display is technically similar to AMOLED in that it incorporates a touch layer on the display. This saves power and makes the display thinner and lighter. The result is a single display layer, which saves space for the battery and makes the phone lighter.
Apple’s Falgship iPhones Display used in LG and Samsung OLED TVs. Similar to an organic light-emitting diode, it is similar to AMOLED display technology. It does not require a backlight like an LCD and is made of organic components, resulting in lower battery consumption. It is lighter.
Power Efficiency: Power consumption
To display pixels on an IPS LCD display. You need a good backlight to get the colors right. The life of LCD displays can be said to be the backlight. However, the backlight is always needed to display pixels on the display, so it consumes more power than AMOLED. In general, an LCD display consumes about 15% more power than an AMOLED.
AMOLED displays, on the other hand, do not need a backlight, so organic compounds are exposed to electricity and emit light only where needed on the screen. Instead of providing electricity in the black area, the transistor is turned off so that the true black color can be displayed. Power consumption is also cheaper than LCD.
Always On Display (AOD), which is popular on smartphones these days, is only suitable for AMOLED displays, and for LCDs, the backlight does not emit real black because the backlight does not appear as dark as AMOLED / OLED displays. In AMOLED AOD, the clock, It only illuminates small areas such as dates, and the rest of the transistors are completely turned off, making it look power-efficient.
That’s why SmartPhones manufacturers do not include the Always on display feature on LCD displays. (LCDs can be jailbroken using AOD on an app (or) LCD iPhone, but as mentioned above, the black backlight is not visible, so you can see the backlight significantly at night.)
And in Night Mode, the AMOLEDs are in real black and the LCDs are in black, with the backlight on. This is the main disadvantage of LCD.
Cost Efficiency: Production cost
Cost of Organic Compounds for AMOLED Displays The raw materials used are more expensive than LCDs and production is more complex and difficult than LCDs. So a broken AMOLED display costs almost half the price of a phone. It is true that LCDs are cheaper than the ones here, but they are cheaper and cheaper to produce.
Life Span: Life Span
Because AMOLEDs use organic components instead of backlight, these components have a shorter lifespan than backlights. It combines three basic colors: red, blue, and green to produce an image. Of the three colors, Red and Green last longer than Blue. If one of these three colors, especially the blue organic compound, is missing, the biggest problem with AMOLED displays is screen burn-in. Therefore, you should avoid having the same wallpaper on AMOLED displays all the time.
On LCDs, if screen burn-in is almost non-existent, the backlight returns to its original state. AMOLEDs are difficult to restore.
The letter is too long to conclude. There are two main types of display technologies: AMOLED You need AOD. There are pros and cons to battery life, but the downside is expensive. There are some color irregularities. Screen Burn-in
IPS LCD displays are color correct. It is cheaper. It has the advantage of not being able to burn-in. No AOD (it looks inconvenient, phone manufacturers do not add it); The colors can be dull and dry.
So the advantages of two displays Once you know the drawbacks, I think the choice of a SmartPhones will go a long way in terms of display issues.
If all else fails, get ideas from others.
