Nowadays, display technology has ushered in a new cycle of rapid iteration, and new display technologies have been continuously broken through and entered the terminal market. Among them, the emergence of transparent OLED display technology has greatly improved the traditional transparent display technology in terms of form, display effect, transparency, and solution richness, greatly improved the transparent display segment, and also provided more possibilities for its application in the field of commercial display. Let us take a deep look at transparent OLED display from the aspects of display principle, functional characteristics and advantages, and its actual application scenarios.
Technical principle
With the advantage of independent self-luminescence of panel materials, OLED self-luminous TVs can break the traditional display form and achieve better transparency and picture quality. Among them, transparent OLED is the existence that breaks through traditional display. OLED is actually the abbreviation of Organic Light Emitting Diode, which is a device that converts electrical energy into light energy. It means that each pixel on the screen will emit light by itself without relying on an additional backlight source.
The working principle of OLED transparent screen involves using OLED materials to manufacture light-emitting elements on a transparent base plate, and adjusting the current intensity to control the luminous brightness of the OLED material, thereby realizing the display of images and videos. Simply put, the basic principle of transparent OLED display is to combine a transparent conductive layer, an organic light-emitting material layer and a transparent substrate layer. The transparent conductive layer has excellent conductivity and transparency, and can conduct current while maintaining the transparency of the screen. The organic light-emitting material layer is responsible for emitting light. When the current flows through the conductive layer, the organic light-emitting material emits light of a specific color to form an image. The transparent substrate layer plays a supporting and protective role, and has transparency.
Advantages and characteristics
Compared with other transparent screen technology solutions, the advantages of OLED transparent display are incomparable. It has huge advantages in transparency, color display, and display form.
First of all, compared with traditional transparent display technology, the transparency of transparent OLED display can even reach 45%. It should be noted that the transparency of traditional LCD transparent display can only reach 10%. This advantage allows this transparent OLED display to more perfectly integrate the displayed information with the background, and can expand more application scenarios.
Relying on the self-luminous characteristics, transparent OLED display can present more vivid and natural color performance, achieve seamless connection with digital content, and enhance the shocking effect of the picture. At the same time, transparent OLED display also has a wide viewing angle. Whether it is viewed from the front, side or tilted angle, its display effect will hardly decay, and it can achieve all-round display.
At the same time, relying on its inherent advantages, transparent OLED screen can completely abandon the concerns that traditional transparent display technology requires backlight module support, and the weight and volume can be achieved to the extreme. Ultra-thin thickness can also broaden the utilization rate of space, and the product form can also be changed accordingly according to the usage scenario. While improving the utilization rate of space, it can even break the space limit and create more visual space. This has gained innate advantages that other transparent display technologies cannot match in commercial displays, transportation tracks and other scenarios.
