A thin and light display that is easy to use for all people

Current mainstream liquid crystal displays (LCDs) require an LED backlight on the back to serve as the light source.

However, OLED (Organic Light Emitting Diode) is a self-emitting display that does not require a liquid crystal layer or LED backlight.

OLEDs are less than half the thickness and about half the weight of ordinary LCDs.

As such, OLEDs are thinner and lighter than LCDs, making them suitable for use in products that are carried around or used for long periods of time, as well as products that are used by children.

Low power consumption reduces environmental burden

A liquid crystal display (TFT-LCD) displays images and video by turning on all the LED backlighting when it is on, and blocking or passing the light through the liquid crystal molecules.

On the other hand, OLED (Organic Light Emitting Diode) is composed of self-luminous elements and displays images by emitting light from only the necessary pixels.

For this reason, OLED consumes less power than TFT-LCD for images and videos that require only a small number of white pixels (low lighting rate), such as text display.

The graph below compares the power consumption of TFT-LCD and OLED.

The graph below shows a comparison of power consumption between TFT-LCD and OLED, showing that OLED consumes less power when the lighting rate is 40% or less.

As you can see, the use of OLEDs not only prolongs the battery life of the product, but also contributes to energy conservation and the SDGs.

When a liquid crystal display (TFT-LCD) is used to display an image or video that contains black color, the liquid crystal layer cannot block 100% of the light from the backlight, and the black area also emits a small amount of light. (Left image)

On the other hand, OLED (Organic Light Emitting Diode) does not emit light in the black areas of the pixels, so it is able to express a darker black color than TFT-LCD, resulting in a clear and easy-to-see display with a high contrast ratio. (Right)

Self-luminous displays are suitable for products that are used at night or in dark places, such as home theaters and car interiors.

Wide viewing angle for a beautiful view from any angle

In a liquid crystal display (TFT-LCD), the LED backlight, which serves as the light source, is located behind the liquid crystal layer, so when viewed from an angle, the light is blocked, resulting in a decrease in brightness and contrast ratio and changes in chromaticity.

However, OLED (Organic Light Emitting Diode) has a wide viewing angle due to its self-generated light and thin structure, so text and images can be seen clearly from any angle.

OLEDs are more suitable than TFT-LCDs for places where the display is viewed from an angle, such as sitting in the driver's seat of a car and looking at the air conditioner or audio system in the center cluster.

100 times faster response time, resistant to low temperature environments

The response time of OLED (Organic Light Emitting Diode) is about 1/100th that of liquid crystal displays (TFT-LCD), and is ultra-fast at less than 0.05m seconds.

TFT-LCDs change color and brightness by changing the orientation of liquid crystal molecules through the application of voltage, while OLEDs change brightness instantly when the current is changed, resulting in a faster response time than TFT-LCDs.

In addition, because liquid crystals have liquid properties, their rotational viscosity increases in a low-temperature environment below 0℃, resulting in worsened responsiveness and abnormal behavior.

OLEDs can be used in harsh environments without any change in responsiveness even at temperatures as low as -40℃.

Comparison with other displays

In addition to OLED (Organic Light Emitting Diode) and TFT-LCD (Liquid Crystal Display), there are many other types of displays, each with different advantages and disadvantages.

In this section, we will explain the features of OLED (Organic Light Emitting Diode) and compare it with LCD (TFT-LCD), micro LED (mLED), and e-Paper (electronic paper).

* Assuming 2inch, color product, 30% lighting rate

Beauty of the display

As for the resolution, there is no significant difference between the two types of displays, which are capable of high resolution of 250~300ppi.

The brightness of OLED and TFT-LCD is almost the same, 200~300cd/m2, and mLED is said to be capable of even higher brightness.

OLEDs and mLEDs are self-luminous displays, which means they have a higher contrast ratio than TFT-LCDs, which block the light from the backlight to produce a darker black color.

In addition, TFT-LCDs have a narrow viewing angle, so when viewed from the left, right, up, down, or diagonally, the brightness decreases and the chromaticity changes. 

However, OLEDs and mLEDs, which are self-emitting displays, have a wide viewing angle of 160° or more, so the display looks beautiful from any angle.

The response time of OLEDs and mLEDs is extremely fast, less than 1/100th that of TFT-LCDs, so there are no afterimages even when the image changes quickly.

Based on the above results, OLED is a very good display in terms of beauty and appearance.

Lifetime

OLEDs (Organic Light Emitting Diodes) and LCDs (Liquid Crystal Displays) lose their luminous efficiency and gradually lose their brightness after prolonged use.

In general, OLEDs are said to have a short lifetime, but as shown in the figure below, the actual lifetime (half-life of luminance) is more than 10,000 hours, and assuming 2-3 hours of use per day, it can be said to have a lifetime of more than 10 years.

OLEDs can be used in many products without any problems, except for some products that will continue to operate for longer than 10 years without maintenance or parts replacement.

Command-type LCD module

Space saving and Miniaturization

A typical TFT-LCD has a thickness of about 5~15mm, while mLED and E-Paper have a thickness of about 0.7mm.

The thickness of OLEDs is about 0.9~2.5mm, which is much thinner than TFT-LCD, enabling products to be smaller and space-saving.

OLEDs are also light in weight, making them suitable for products that need to be smaller, thinner, and lighter, and for products that are worn or carried around.

Mass Production

TFT-LCD, OLED, and E-Paper are being mass-produced by many companies and are easy to procure at low cost.

On the other hand, mLED has the following issues

◎ Flip chip bonding is required instead of general wire bonding.

◎ The process for mounting a large number of LEDs with high accuracy and speed has not yet been established.

Due to these issues, the cost is high and mass production is difficult.

TFT (Thin-Film-Transistor) is an active matrix screen technology, which is more expensive than monochrome LCD but has a sharper image.

What is a TFT LCD Display?

TFT (Thin-Film-Transistor) Liquid Crystal Display is a small display type, where a transistor is embedded into each crystal gate; these transistors are then printed on thin-transparent film. 

Also designed in the late 1980s, TFT display technologies are just another variation of LCDs that offer more fantastic colour, contrast, and response times than available passive matrix LCDs.

Understanding TFT LCD

The word TFT means Thin-Film-Translator. It is the technology that is used in LCD or Crystal Display. Here you should know that this kind of LCDs is categorically referred to as active-matrix LCDs. These LCDs will hold back some pixels while using different pixels. TFT LCDs have capacitors and transistors. These two elements are crucial in ensuring that the display monitor functions using minimal energy without running out of operation.

Characteristics of TFT Display Technologies

TFT Liquid crystal display products are diversified, convenient and versatile, simple to keep up, upgrade, update, long service life, and have many alternative characteristics.

The display range covers the appliance range of all displays from one to forty inches and, therefore, the giant projection plane could be a large display terminal.

Let me explain. As you can see, TFT has an excellent colour display and clarity.

In a TFT screen, the structure of the crystals leads to angular retardation within the light-weight. 

Features Of TFT Display

Before we go into the differences, let’s talk about the features of each technology. First, it’s interesting to discover that the TFT display technologies are the most common colour display technology; more monochrome displays still out-sell colour due to lower cost and lower power consumption. However, the limited poor visibility of TFTs in direct sunlight is their downside; but I’m getting ahead of myself here.

TFT display technologies have developed and become quite popular in tech circles.

The features offered with this advancing technology are:

1. Superior colour display – for technology that requires it or for consumers that desire colour screens

2. Not only is the colour superb, but the clarity is outstanding.

3. Features an extended half-life (half-life is that the amount of time in hours before the show is 50% as bright as once it was 1st turned on) than OLEDs and comes in variable sizes, from below an in up to over 15 inches

4. Capacitive Touchscreen or bit panel that is within the majority of Smartphones and permits for additional functionality, specifically for zooming and scrolling.

5. Resistive touch panels which are lower in cost and are usually standard on most TFT devices

6. Aspect ratio control refers to a screen’s ability to keep up a side ratio of a source image at the hardware level, and 1:1 pixel mapping is used to literally “map” the exact number of pixels specifically within the supply resolution to pixels on the screen.

7. No “ghosting” (ghosting is once a picture can stay for a brief time when instead it ought to be off)

8. Variety of displays, which may be interfaced through a range of bus sorts, as well as 18 and 24 bit for red/green/blue, LVDS, and 8 bit and 16 bit for a CPU – several controllers allow for two or a lot of different types of interfaces on the constant TFT screen.

Let me explain. As you can see, TFT has an excellent colour display and clarity.

Advantages & Disadvantages of TFT For Use In LCD Displays

We’ve been talking mainly about Smartphone screens, but since both technologies work on smaller screens, such as clocks and timers or digital thermometers, let’s focus on those.

Advantages Of TFT Display Technologies

Steve Jobs said it best: “Design is not just what it looks like and feels like. Design is how it works.” I tend to agree with him. With TFT display technologies, less energy consumption is a big deal, especially when dealing with more giant screens, and of course, less electricity means lower cost overall. The visibility is sharper, which means no geometric distortion, good for these tired, old eyes. The response time and physical style of the screens are appealing. TFT displays may save space and be placed virtually anywhere in an office or home because of the brightly lit feature and crisp, clear images.

Disadvantages Of TFT Display Technologies

Some cons of TFT screens deal with the viewing angle, which creates distortion, resulting in a less-than-perfect image. The static resolution, meaning the resolution can’t be changed, may also cause a problem, but newer models have tackled that issue. The accuracy of the display of colours is not perfect, specifically solid blacks and bright whites, so when printing an image, it may not display the spectrum of colours.

TFT Displays: Pros 

1.The best thing about TFT technology is that it uses much less energy to function when operated from a bigger screen. It ensures that the cost of electricity is reduced, which is a beautiful plus point.

2.It creates sharp images with no problems for older and tired eyes.

3.The screens made with TFT technology have a beautiful physical design and appearance.

TFT Displays: Cons

1.One of the significant problems of TFT technology is that it fails to create a wider angle of view. 

2.When the TFT screen is used for printing images, the technology fails to show the exact colours as it is there in the actual pictures.

Final Words

And there you have it. In the future, even this superb technology will change, and new, more exciting technology will take its place. You don’t want to miss it.
