In this ever growing technological era, the purpose of using mobile phone has changed. Previously the only purpose of buying a mobile phone was communication but now the transformation of feature phones to smartphones has opened new choices for users to buy a device. Now people are more interested in design, camera, space and etc rather than just dialling a call.
Smartphone has become a basic necessity of our life and has become or mini-computer that is with us all the time. Now it performs multiple functions in just a tap of fingers. With the growing technology reforms, we come across new features in term of design in any smartphone. AMOLED and OLED displays are commonly in talks nowadays. These are the two basic display technologies that are available today and many people are curious to know the difference between them.
So keeping in view the demand, PhoneWorld has decided to introduce our readers to the OLED and AMOLED display technologies. We will discuss the properties of both display technologies followed by the difference between them.
The word OLED stands for Organic Light Emitting Diode. Basically, the OLED Displays have an LED which is made up of an organic material that emits light when current is passed through it. OLED displays are widely used to display vibrant colours. This type of display is smaller, flexible and comparatively thin as compared to the old LED technology. While transmitting dark colours, these displays consume less power.
Advantages of OLED Display:
- As discussed above the organic layers of OLED displays are much thinner, lighter and more flexible.
- OLEDs are lighter due to the light emitting layers, also they are flexible instead of rigid.
- OLEDs do not need backlighting like LCDs
- OLEDs are much brighter, unlike LEDs.
- OLEDs display can be easily produced
- They can be made to larger sizes.
- OLEDs have large fields of view i.e. around 170 degrees.
Disadvantages of OLED Displays:
Though OLEDs are widely used displays but they also have some disadvantages:
- Life of OLED display is shorter than LCD and LED display technology.
- The OLEDs have variation in colour balance.
- OLEDs are not water resistant so they easily get damaged with water.
Fields Where OLED Displays are used:
The OLEDs are widely used in different areas:
- OLED displays are used in television display creation
- Used in smartphone screen development
- Used in computer monitor screen implementation.
- It is also used for creating flexible and bendable lighting, wallpaper and even for transparent lighting.
AMOLED stands for Active Matrix Organic Light Emitting Diode. THis type of display is based on active matrix system and has thin film transistor (TFT) to control the flow of current in each pixel. It has two thin film transmitter with different workings. One is used to start and stop charging of the storage capacitors and other to facilitate the charging of the capacitors.
When it comes to the size of the display, AMOLED has no limitations and its power consumption is lesser than OLED and LED displays. It is the latest technology available in town and is actively pursued by many device makers due to its incredible performance. It is thinner, lighter and flexible than any other display technology like LED, LCD technology.
Areas where AMOLED displays are used:
- Smart watches
- Portable music players
- Games consoles
- Music production hardware
- Digital cameras
Advantages of AMOLED:
There are many advantages of AMOLED Displays due to which it is gaining popularity. Some of them are as follows:
- AMOLED can be easily embedded into a display of any size.
- It has a much faster refresh rate as compared to PMOLED.
- It is widely used in all industries.
- They offer much better viewing angles as compared to the IPS LCD.
Disadvantages of AMOLED:
However, everything has certain limitations. Some disadvantages of AMOLED displays are as follows:
- One of the biggest disadvantage od AMOLED display is that its quality degrades with time.
- The AMOLED display is very prone to screen burn-in.
- The AMOLED displays are extremely costly as compared to other display technologies.
Conclusion- OLED VS AMOLED:
The smartphone displays have evolved more than one realizes in this technological era. Display screens are like the windows to the mobile world which has witnessed a dramatic evolution in terms of innovation and technology. Just in a few years, People have become more choosy while selecting a phone in terms of all the features but display always stands out. All smartphone giants are trying to provide their users with the best devices incorporating latest technologies. . AMOLED is essentially a type of OLED and a better version of OLED so there is no question there as to which one is better.
