Transparent display: the new darling of the market, open the future horizon

Since 2024, transparent display has become another darling of the market: LG launched the world's first wireless Transparent Oled TV, Lenovo launched the first concept new Micro-LED transparent screen laptop ThinkBook, Samsung exhibited the first transparent Micro-LED TV...

The rapid development of a new generation of display technology has spawned more and more innovative product forms and application scenarios. Transparent Display brings more imagination to the development of the display industry through a new visual experience and huge application potential.

The transparent display screen is mainly made of conductive glass as the substrate material, and is made into transparent electrodes by screen printing technology. On this basis, a circuit is designed to connect the electrode with the driver chip to realize the display function. At present, the transparent display has a variety of technical solutions such as film screen, crystal film screen, liquid crystal screen, holographic invisible screen, double-sided transparent screen, OLED transparent screen and Micro LED transparent screen.

01  LED crystal film screen

The LED transparent screen is mainly an innovation of the substrate. LED crystal film screen is a soft and transparent crystal film material as the carrier, the LED chip is encapsulated in it, forming a thin-film display device, and the brightness and color of the lamp bead are controlled by the driver chip to form an image. The product has good flexibility and bendability, and the light transmittance is as high as 95%, which is widely used in commercial and architectural decoration fields.

02  LCD transparent screen

LCD transparent screen is derived from liquid crystal display technology, while maintaining a certain display quality, increase the characteristics of transparency. It works by using an external current to control the arrangement of liquid crystal molecules, ‌ to change the transparency of the display. ‌ products are commonly seen in intelligent glass, ‌ electronic display, ‌ window advertising and so on.

03  LED holographic invisible screen

The key technology of holographic invisibility screen is holographic imaging. It uses the light emitted by the LED light source to decompose the image into a wave front through holographic imaging technology, and then recombine the wave front into a holographic image through the interference and diffraction of the light. Holographic invisible screen has a wide range of application prospects, such as smart home, virtual display, movie production, commercial advertising and other fields.

04  LED double-sided transparent screen

JDI Rælclear double-sided transparent display

The representative manufacturer of the double-sided transparent screen is JDI, a Japanese display company. Its Rælclear transparent display is designed based on a new liquid crystal and light conduction system and superimposed field sequence drive, which does not need color filters and polarizing filters, and can achieve positive and negative visibility on both sides. In this design, the liquid crystal layer is sandwiched between two glass substrates, and the LED is configured as a light source at the edge of the display screen. The light emitted by the LED is fully reflected repeatedly in the glass substrate, and finally reaches the display screen to form an image.

05  OLED transparent screen

LG's world's first wireless transparent OLED TV

Because of its self-luminous properties, OLED is very suitable for the manufacture of transparent displays. Its working principle is to use transparent organic self-luminous materials, through the current excitation of each pixel and control its opening and closing, to achieve transparent display. OLED transparent screen has extremely high transparency and excellent color performance, is an important development direction of the current transparent display technology, and is widely used in intelligent transportation, exhibition, indoor and outdoor design and other scenarios.

06  Micro LED transparent screen

Micro LED transparent screen is the use of Micro LED light chip on the glass substrate to achieve high transmittance display effect, with high transparency, high brightness, high contrast, in commercial display, vehicle display, advertising and other fields are widely used. Since the beginning of this year, Micro LED transparent screen has repeatedly appeared in various exhibitions, Samsung, Lenovo, AU, BOE, TCL Huaxin, Tianma Microelectronics, Liade and other enterprises have exposed related products, Micro LED transparent screen thus quickly emerged.

In recent years, the rapid development of display technology, transparent display as a representative has been practical application in a variety of occasions, the future will continue to develop in the direction of diversification and intelligence, create more effective supply for the market, add more vivid color for human settlements. How to implement the new technology into the product, and then implement it into the specific scenario, and achieve the perfect integration of technology and market will be the key to the development of the future industry.
