OLED vs LCD - advantages and disadvantages

OLED displays are the latest technology for lights that have brought a revolution in the TV industry. This display system is smart, ultra-thin, and offers safe viewing of your favorite programs with the entire family. Although the structure of this panel is complex than the LED and LCD versions, it offers better display and provides comfort to the eyes. Let's find out more about in the below discussion about OLED technology.


What is OLED?


OLED is the short form of Organic Light Emitting Diode. This is a light technology that is another part of the OLED display system. This system is normally used in automotive applications and general lighting processes. This is the most used technique because of its homogeneous light, lightweight, and ultra-thin form factor, and other facilities. The technology of OLED can be utilized to create SSL or solid-state lighting, and this will be made of thin carbon-based organic layers between two electrodes. If there's a DC supply the electrons and holes are inserted from the cathode and anode to transform it into the organic layers. The moment the energized states comers to a relaxed position, the light is emitted from the system.


The wavelength and the color of the oled light emits are based on the structure of the molecule that creates the energized state of the system. There are different types of emission colors available but for OLED lights the organic mixture is selected with care, this is to design a better spectrum for the white to lights to emit.


The panel of OLED lighting begins with a transparent substrate, this provides the structure and the other optical items. The substrate has the patterned layer, normally an ITO is used, which works as the bottom of the anode and electrode. Ultra-thin layers are used on the anode area, and then a metallic cathode. Then the entire OLED structure is very thin and the layers contain various organic ingredients. Other than the LED system the organic materials of OLED are different. The light emission areas cover a broad aspect than its previous version. The wide surface coverage also offers the panels increased contrast if there are electrode patterns, this allows the delivery of other communication levels.


Where can OLEDs be found today?


OLED system is mostly found in smartphone devices; several high-end mobile manufacturing companies use the same. Based on its use more than five hundred million OLED panels are manufactured every year. The need for this system is very high in different display industries and the market is increasing as the OLED system is offering better versions and features which is ten times better than the LED system. It's is expected that by the end of 2022 there will be more than one billion productions of OLED panels.


Other than lights OLED is also used in TVs. Some top TV panel companies offer OLED-based systems in their televisions. TV manufacturers nowadays using this technology to offer award-winning OLED TVs. These televisions offer ultra-thin screens and fine displays. In the future years, it is expected that there will be better technologies like quantum-dot hybrid and ink-jet printed OLEDs.


What is the technology of OLED? Structure of an OLED display


The main part of the oled displays is the OLED emitter. This is an organic ingredient that produces light when electricity is on. The base structure of the OLED system is a layer that stays between an anode and a cathode. Modern OLED appliances have more layers just to make them durable and efficient, but the primary functions stay the same. An OLED panel is made of the front plane, backplane, electrode, encapsulation layer, and substrate. This system is highly sensitive to moisture and oxygen so the layer is complex to understand.


The backplane and the substrate of the OLED display are similar to LCD, but the front plane is unique to OLEDs. Recent OLED displays are made with shadow masks and vacuum evaporation. This is a simple method but not very efficient, also to upgrade to the bigger substrates. There are soluble OLED materials and these are used as printing methods mostly for inkjet services.


OLED vs LCD - advantages and disadvantages


Innovation and competition are the main sections of the electronics market that have been facing uninterrupted growth for decades. Manu customers purchase different types of technologies. The expansion of the system has become complicated throughout the years and has become more efficient with the innovations.


Market Trends and Performance: The popularity of the smart consumer system has spread globally, and with that, the need for a better display system is reaching the top. The LED system is no longer reigning over the market as today's consumers are looking for something new and advantageous. The better service and display with internet connectivity to their television devices have made life easier for smart lives. In the future, experts have predicted that the OLED market will expand at least 14.27% than the current and previous years.


Recently, the OLED TV system is outperforming the LED products and leaving behind the old technologies. OLED systems are available in different formats as you will get 88 inches to satisfy the demands of better and premium displays for TV. On the other hand, AMOLED set the marks of the best picture quality in the industry of smartphones. There are foldable OLED devices that have become popular in the electronics market and offer better performance for the future.


Comparison of OLEDs LED LCDs: Traditional LED displays works based on LCD technology, which is tested and tried structure. The LCD screen is produced by a thin section of transistor grid that uses small crystalline components. This procedure is of the dark and light pixels, but the light emits from the LED storage. The best way to check LCD screens is that it uses LED backlight for better contrast and dimming of the screen. It offers a better display than the previous version of it. Also, OLED offers safety for the eyes which will not irritate your vision. LED lights were harsh and they can affect the eyesight especially of children. OLEDs it has brought a better solution to TV watching.


Advantages of OLED Display


  1. * OLED is a thinner version of a display screen that is made of crystalline layers used in LCD and LEDs.
  2. * The light-emitting layer is high in OLED; the substrate of the display is far more flexible than rigid. The substrate of OLED is plastic or it can be a glass that is generally used in LCDs and LEDs.
  3. * LED is dimmer than OLED and this is because of the thin organic layers that help in the light emission. Also, OLED does not need glass support which is one of the main components of LCD and LED. OLED can use plastic material for the fine display.
  4. * The system of OLED does not require backlighting as the LCD needs it. LCDs blocks the backlight areas to show the images to you but in the case of OLED, the images are generated by themselves. Also, just because it doesn't need backlighting, the power consumption is less than the other light systems.
  5. * Battery-operated devices are best used in this category where power consumption is lower.
  6. * OLED is easy to manufacture and it can be made into a larger size. Also, the best benefit here is that OLED supports plastic. That's why it can be created into large sheets. While glass is difficult to expand.


If you want a large field view, then OLED is the best for it. As LCD blocks the light to show the images on the screen, OLED does not support such things as it generates the images all by itself and has built-in lights too. Thus, this offers a better view of anything on the screen.


Disadvantages of OLED


  1. * There aren't many disadvantages of OLED, but it can cause some issues such as:
  2. * The colors of OLED can be problematic and blue organics have a shorter lifetime than the others.
  3. * The manufacturing process is expensive and water can damage the OLED system.


Advantages of LCD


  1. * LCD is still a popular system and consumers who aren't capable of buying OLED systems opt for LCD. Here are the advantages of the same.
  2. * The LCD system can be large but not larger than OLED. However, it can be 60 inches to 150 cm.
  3. * This has no geometric distortion
  4. * This is thinner than CRT monitors and power consumption is less so it emits small heat.
  5. * LCD does not get affected by the magnetic fields.


Disadvantages of LCD


  1. * As there are advantages there are disadvantages of LCD too.
  2. * The temperature becomes high due the environment
  3. * It consumes a lot of power which creates high heat
  4. * LCD is not proper for the environment also it blocks the backlight.
  5. * The contrast and color are not consistent in LCDs.
  6. * It can damage the vision of the user as it can create irritation in the eyes.
