序章
With the continuous development of science and technology, transparent display technology has gradually become a highlight in the field of modern display. With its unique transparency and high-definition display effect, transparent display screens have brought a new visual experience to many fields, such as commercial display, public transportation, smart home, etc.
Among the many transparent display technologies, LED透明スクリーン and OLED transparent screens have attracted much attention in the market with their respective advantages.
1. Introduction to LED transparent screen
LED transparent screen, also known as transparent LED display, is a major innovation in modern display technology. The core of this display lies in its unique structure. It uses a large number of micro LED lamp beads as display units and cleverly installs these lamp beads on a transparent substrate. These substrates are usually made of glass or high-strength plastic, which ensures the overall transparency of the screen and the stability of the structure.
In the non-luminous state, the transparent substrate of the LED screen allows light to penetrate freely, making the scene behind the screen clearly visible without any obstruction. This feature makes the LED transparent screen have extremely high application value in scenes such as commercial display, window decoration, and architectural glass curtain walls because it can provide rich visual information without interfering with the line of sight.
When the LED transparent screen is turned on, tens of thousands of micro LED lamp beads will light up according to the preset pattern or video content, forming a clear and bright display effect. These LED lamp beads have excellent brightness and color expression and can present bright and vivid images to attract people’s attention.
The characteristics of LED transparent screen mainly include:
高い透明度： When the image is not displayed, the screen is almost completely transparent and can be well integrated with the surrounding environment.
高輝度と鮮やかな色彩: LED lamp beads can emit high-brightness light, and the colors are bright and full, and the display effect is outstanding.
Strong plasticity: LED transparent screens can be made into various shapes and sizes to meet different display needs.
省エネと環境保護: LED has high luminous efficiency, low energy consumption, and low heat generation, which is conducive to energy saving and environmental protection.
長い人生： LED lamp beads have a long life, high reliability, and low maintenance cost.
2. Introduction to OLED transparent screen
OLED transparent screen, the name may sound a bit complicated, but in fact the principle behind it is relatively intuitive and easy to understand. First of all, we need to understand OLED, that is, organic light-emitting diode (Organic Light-Emitting Diode). This is an advanced display technology, and its core lies in the characteristic of “self-luminescence”.
Imagine that traditional LCD TVs or computer monitors need a backlight to illuminate the pixels on the screen, but OLED is different. Each of its pixels has the ability to self-luminesce.
This means that when we want to display an image or text on the screen, we only need to activate the corresponding pixels, and they will emit light by themselves without the need for additional light sources.
Now, when we combine OLED technology with transparent display screens, we get OLED transparent screens. The special thing about this screen is that its substrate is transparent, and the OLED pixels are evenly distributed on this transparent substrate. Therefore, when the OLED pixels are not emitting light, the entire screen appears transparent, and we can clearly see the scene behind the screen.
The main features of OLED transparent screens include:
Self-luminescence: OLED pixels can emit light independently without a backlight, making the screen thinner and more transparent.
High contrast and viewing angle: The contrast of OLED transparent screens is extremely high, which can present deeper blacks and brighter colors. At the same time, because the OLED light-emitting layer is flat and the light is evenly distributed, the screen has a wider viewing angle.
Fast response: The response time of an OLED transparent screen is extremely short, and it can respond to image changes quickly to avoid smearing.
High color saturation: The color saturation of an OLED transparent screen is as high as 98%, which can present more realistic and vivid images.
柔軟で曲げやすい: OLED materials are flexible and can be made into bendable and foldable displays, providing more possibilities for future display technology.
3. Performance parameter comparison
1). Brightness and contrast
- LED透明スクリーン:
The LED transparent screen usually has a high brightness performance, and the basic brightness can reach 4000-5000cd/㎡. This is because the LED lamp beads are directly exposed to the outside without any obstruction, so the brightness is higher.
However, at high brightness, the contrast of an LED transparent screen may be affected to a certain extent because the high-brightness background may reduce the contrast between the image and the background.
- OLED transparent screen:
The brightness of an OLED transparent screen is generally between 1000-1500 nits, which is slightly lower than that of an LED transparent screen. However, due to its self-luminous characteristics, the contrast of an OLED transparent screen is extremely high and theoretically can reach infinity.
This makes the image appear black and white and more vivid in color when it is presented on the OLED transparent screen.
2). Viewing angle and color
- LED透明スクリーン:
The viewing angle of the LED transparent screen is generally around 140° horizontally and 140° vertically. Within this range, the color performance is relatively stable. However, when the viewing angle deviates from this range, the color may be distorted.
- OLED transparent screen:
The viewing angle of the OLED transparent screen is wider because the OLED light-emitting layer is flat, and the light is evenly distributed, so the color performance remains consistent at almost any angle. In addition, the OLED transparent screen has a significant advantage in color saturation and can present more vivid and realistic images.
3). Response time
- LED透明スクリーン:
The response time of the LED transparent screen is usually below 3ms, which means that when displaying dynamic images, the LED transparent screen can respond to image changes faster and avoid smearing.
- OLED transparent screen:
The response time of the OLED transparent screen is even better, usually below 1 ms. This allows the OLED transparent screen to provide smoother and more coherent visual effects when displaying high-speed dynamic images.
4). Power consumption and lifespan
- LED透明スクリーン:
The power consumption of the LED transparent screen is relatively low, thanks to the efficient light-emitting characteristics of the LED lamp beads. However, the specific power consumption level depends on factors such as screen brightness and size. In terms of lifespan, LED transparent screens usually have a longer lifespan and can run stably for tens of thousands of hours.
- OLED transparent screen:
The power consumption of OLED transparent screens is also relatively low, but due to its self-luminous characteristics, each pixel needs to be powered independently, so the overall power consumption may be slightly higher than that of LED transparent screens of the same size.
However, the lifespan of OLED transparent screens is also very long, and they can run stably for more than tens of thousands of hours. In terms of energy saving and long-term operating costs, both have good performance.
