You almost always think of LCD and OLED only when thinking of display panels. OLED is a technology that is already popular and used in various display devices widely. In addition, MicroLED and QLED have also become the next generation of display technology. But the question is, who can challenge LCD?

  • What are the differences between OLED, QLED, and MicroLED?
  • Who will be the next generation of display technology?
  • Who can challenge LCD?

1. OLED Screens Advantages And Disadvantages

OLED, an organic light-emitting diode, refers to the phenomenon of organic semiconductor materials and light-emitting materials leading to luminescence through carrier injection and composite driven by electric fields. Here are some advantages of OLED screens given below:

Advantages of OLED

  • Spontaneous light is the biggest advantage of OLED or self-luminous OLED televisions that can be made very thin. Even LG has made OLED TVs a stunning 2.57mm thick, with the widest part no thicker than 5mm. 
  • Moreover, OLED can be switched on and off for each pixel because of its spontaneous light of pixels. 
  • It can achieve the partition backlight at the pixel level, which theoretically can acquire indefinite contrast.
  • OLEDs have a wide range of viewing angles and consume less power due to their self-luminous nature.
  • OLED also has a much better color performance with a wider color range.
  • OLED has a special feature produced on flexible substrate materials such as resin and plastic to achieve a soft screen. Curved and foldable phones take advantage of this feature.


    Disadvantages of OLED

    But OLEDs also have a destructive drawback which is given below: 

    1. Organic materials used in OLEDs age faster than inorganic materials used in LCDs. 
    2. A characteristic of OLED displays leaves a residual image when left standing for a long time. 
    3. Although many technologies can help screen burning, they still cannot be solved well.

    2. QLED Advantages And Disadvantages

    QLED is a quantum dot light-emitting diode, having all the advantages of OLED, such as low response speed, spontaneous light, wide color range, etc. 

    Advantages of QLED

    • QLED has longer life as it adopts inorganic quantum dot material.
    • It has no screen burning phenomenon other than OLED organic material.

    Disadvantages of QLED

    • The quantum dots of QDS are susceptible to heat and water; a new manufacturing process needs to be developed as they cannot adopt the same manufacturing process as OLED.
    • QLED Technology has just started for a short time, having limitations such as unstable component life, difficult research, low reliability and efficiency, and difficult development of the solution manufacturing process. 
    • At present, QLED only exists in the laboratory.
    • There is still a certain distance from its commercial use.

    You can ask a question 

    Has Samsung not launched the QLED TV? 

    The answer is that the QLED TV on the market is not QLED in the real sense. The QLED TV can be regarded as an upgraded version of the LCD TV. 

    TV has better picture quality and color performance than traditional LCD TV by adding a layer of quantum dot film in front of the backlight of LCD TV.

    The QLED TV on the market currently is photoluminescence need to rely on the backlight. The real QLED is electroluminescence, which can identify the spontaneous light of pixels.


    3. Expensive Micro LEDs Advantages And Disadvantages

    The Micro LED is the same as the LED light billboard we see on the road, except the Micro LED takes each bead to the micron level. 

    Advantages of Micro LED

    • Micro-LEDs are also pixel-level spontaneous light like OLED. 
    • They reduced traditional inorganic LED arrays, and each LED pixel in the 10-micron size can be addressed and burned individually.
    • Micro LEDs are more efficient and brighter than existing OLED technology but consume less power. 

    Disadvantages of Micro LED

    • The big problem of the micro-LED is that its manufacturing process is difficult.   
    • The most difficult one is “massive transfer technology,” which means how to transfer tens of millions of pixel light sources to the substrate.
    • High production difficulty and low yield lead to the high price of Micro LED. 
    • The current large-size Micro LED TV price is not affordable for ordinary people.

    4. Custom Segment LCD Displays

    LCDs are more affordable under mass production, especially segment LCDs are very high in demand and affordable.

     Advantages of Custom Segment LCD Displays 

    • Low unit cost
    • Low up-front tooling cost. 
    • Estimated tooling Non-Recurring Engineering (NRE) cost for a custom segment LCD can run as low as $900.
    • The one-time NRE fee allows product developers to design and build the display they need for their product within their budget.
    • Add as many varying icons as you need.
    • Low lead times
    • Customize the character height and glass size to meet your requirements.
    • Design support provided
    • Seven, Fourteen, or Sixteen segment options are available.

    5. Who Is The Next Generation Of Display Technology?

    Are LCDs, OLED, QLED, MicroLED the next generation of display technology? 

    The answer is that in terms of performance, if all pixels illuminated spontaneously and did not burn the screen, then quads and micro LEDs would certainly beat OLEDs for longer life. 

    But the picture is different when one views the current state of the art. QLED mass production is far away as it is still laboratory. Micro LED has a high cost, low yield, and no real civilian products currently. 

    OLED screens are generally more expensive than LCDs and are already capable of mass production. LCDs are in mass production, can be customized, and are easily affordable.

    At this stage,

    LCDs are still the next-generation display technology. But soon, OLED could replace LCD if it can lower its price even further. But in the long run, OLED is also a temporary technology, with QLED and Micro LED being the final form until LCDs are the popular technology. 

    There is no need to worry too much about which display technology to use for consumers; all are affordable and easy to use. Even QLED and Micro LED will not overturn the LCD if prices do not fall and if they are commercially available.


    6. Final Words

    The LCDs are still popular display as they are cheap, easy to customize, easy to use, and available at affordable prices. If you still have any confusion, contact us with your query; our expert will answer you as soon as possible.

    2. TFT LCD Technology 

    LCD is a liquid-crystal display. Most of the current market uses TFT-LCD or thin-film transistor liquid crystal display technology. TFT-LCD consists of a layer of liquid crystal sandwiched between two glass substrates. The lower glass layer is inlaid with electro-crystals and the upper glass substrate is a color filter. The electric field passes through the crystals created by the electric current and making the original rotational arrangement of the liquid crystal molecules twist. Different colors produce by changing the rotational amplitude of the light passing through and shining on the color filter in different proportions.

    • LCD panels are made using TFT-LCD technology. 

    It Includes:

    • Polarizers
    • Glass Substances 
    • Color filters
    • Colored molecular layers
    • Glass substrates
    • Polarizers
    • Backlight Module 

    It is now quite grown and is used for TV screens and public computers. And It is a low-cost technology that has become the foundation for consumer products.

    After understanding LCD and TFT LCD, let’s move on to LED and OLED technologies. 


    3. LED Technology 

    The LED is called a light-emitting diode, which uses electrical energy to convert into light energy by applying a voltage to the positive and negative terminals in the semiconductor. The electrons combine with the electric hole when the current passes through, and the remaining energy is released in the form of visible light. The direct display LED is commonly used for outdoor traffic lights or TV walls. LED chips are the mainstream TV, screen backlighting, and lighting products.

    • LED technology uses electrical energy to convert into light energy, and it includes:
    •  Optical
    • P-Type Semiconductor
    • N-Type Semiconductor 


    4. OLED Technology 

    Generally, the concept of conducting LEDs is quite similar to that of OLEDs.  But the materials used in LEDs are totally different because OLEDs are called organic Light-Emitting Diodes and shortly OLEDs. The basic structure of OLED consists of an organic material light-emitting layer made on Indium Tin Oxide glass. It is covered with a low power function metal electrode on top of the light-emitting layer. An external voltage drives the light-emitting diode. The cathode electrons combine in the light-emitting layer to emit light and generate energy, producing R, B, and G primary colors depending on the characteristics of the material from the primary colors.

    • OLED technology includes:
    • Polarizers 
    • Substrates
    • Electrodes
    • Electron layers
    • Organic light Emitted layer
    • Electron hole layer
    • Electrodes
    • Substrates 

    The most noteworthy difference between OLED and LCD is that LCDs require LED backplanes and filters and OLEDs are self-luminous.

    Although OLED presents a vivid picture, has low power consumption, and can be bent, the organic material will oxidize, so the life span is relatively short. There will be problems with color burn-in, coupled with high technical content and the high cost. Currently, it is mainly used for small screens only, such as mobile phone screens, etc.

    Now, we will look at advanced display technologies like Mini LED, Micro LED, and Micro OLED. After understanding the fundamental differences between LCD, LED, and OLED.


    5. Mini LED Technology 

    The most automatic difference between Mini LED and Micro LED is the size of the LED crystals. But there is a slight difference from a conceptual point of view; Mini LED is formally known as a sub-millimeter light-emitting diode, while Micro LED refers to the micro light-emitting diode.

    • Micro LED technology no longer requires a filter and liquid crystal layer, and it includes:
    •  Anti-glare and Protective films 
    • RGB micro LEDs
    • Electrodes
    • Substrates

    Mini LED is considered as the transition period of Micro LED. It is an improved version based on the conventional LED backlight and used as the backlight of LCD panels. Micro LED is regarded by the industry as the new generation of display technology and matrixing the LED backlight. It is dedicated to driving inorganic self-lighting or self-luminous alone and allowing longer product life and even perform better than OLED.

    Mini LED technology is currently mainly used in multi-zone backlight displays and large RGB small pitch displays. The multi-zone backlight control function can be achieved by zonal dimmings, such as the screen’s high resolution and enhancing the high contrast ratio, or performing the HDR effect. The effect is similar to OLED displays; another technology uses Mini LED chips to create a display with a pixel pitch lower than Pitch 1. Mini LED chips are another technology used to create large screens with a pixel pitch of approximately less than 1.0 mm, which improves the resolution of LED display screens. It creates a new mainstream specification for display screens.


    6. Micro-LED Technology 

    Micro LEDs will bring a new technological breakthrough. Their use is not only specified to backlighting, as the grains of Micro LEDs are of an indistinguishable grade to the naked eye.  Also, it can directly combine the R, G, and B primary colors into a single pixel, turning it into the concept of one pixel. 

    • The technology is different from the light-emitting structure of previous LCD screens.
    • Huge Transfers
    • Wafer Dicing 
    • Red, Green, and Blue LED wafers

    Moreover, to create a whole new scenario for the LCD industry, the future of Micro LED has a wide range of applications, including automotive screens, VR/AR devices, and high-resolution wearable products. However, Micro LED technology has many significant difficulties, like Mass Transfer yield, packaging testing problems to the next inspection and maintenance. These are all critical challenges and affect whether Micro LED can be mass-produced or not.


    7. Micro OLED Technology 

    As Apple has approached TSMC to collaborate on the development of Micro OLED panels, Micro OLED has been the talk of the town this year. It is not like traditional LCD or OLED for TVs and high-end mobile phones where the screen is built on a glass substrate.

    It is directly mounted on a wafer, which is the essential feature of Micro OLED. Micro OLEDs use a single silicon wafer as the backplane especially suitable for AR, VR, or other display wearable devices.

    It has the advantages of making the display thinner, shorter, lighter, self-luminous, high luminous efficiency, and consuming less power.


    7. Final Words

    All the above LCD, LED, OLED, Micro LED, Mini LED, Micro OLED has their own features and characteristics, and all are useful for humanity’s services. So You can choose one of them according to your need and desire based on their uses.
