What Is A Transparent LED Screen?

Introduction

In today's digital age, display technology is changing with each passing day. As an innovative display solution, transparent LED screens are gradually changing our visual experience and commercial display methods. From high-end retail windows to large-scale building curtain walls, from museum exhibitions to stage performances, transparent LED screens, with their unique "transparent display" characteristics, have brought unprecedented display possibilities to all walks of life. This article will comprehensively analyze the technical principles, product features, application scenarios and future development trends of transparent LED screens, and introduce the innovative contributions of Huamite, a leading domestic company, in this field.

Basic Concepts of Transparent LED Screens

Definition and Working Principle

Transparent LED Display is a high-transmittance LED display device that displays dynamic images or video content while keeping the background transparent by installing micro LED lamp beads on a transparent substrate. Unlike traditional LED display screens, transparent LED screens do not rely on opaque base plates to reflect light, but use a special grid arrangement design that allows light to pass directly through most areas of the screen.

Its working principle is mainly based on the following points:

Using side-emitting LED technology to control the light direction at a specific angle

The LED light strips or lamp beads are spaced relatively large (usually 10mm-30mm) to form a grid structure

Using high-transmittance glass or acrylic as the substrate material

The brightness and color of each LED are precisely adjusted through the control system

Development History

The development of transparent LED screen technology has gone through several important stages:

The initial exploration stage (2000-2010): Researchers began to try to install LEDs on transparent substrates, but due to the limitations of LED size and driving technology, the product transmittance and resolution were low.

Technology breakthrough stage (2010-2015): With the development of LED packaging technology and small-pitch LEDs, transparent LED screens began to be commercialized, and companies such as Huamite launched the first batch of commercial products.

Mature application stage (2015 to present): Transparent LED screen technology is becoming more mature, application scenarios are constantly expanding, product performance is significantly improved, light transmittance can reach 70%-90%, and pixel pitch is also reduced to 3.91mm and below.

Analysis of the core technology of transparent LED screens

Optical design technology

The core challenge of transparent LED screens is to balance the contradictory needs of "display" and "transparency". Huamite has solved this problem through the following technological innovations:

Special LED packaging technology: ultra-thin and miniaturized LED packaging is used to reduce the size of lamp beads while ensuring luminous efficiency. Huamite's Nebula series products use customized LED chips, which are only 1/3 the size of traditional LEDs.

Light guide structure design: Through precise optical lens design, the LED light emission angle is controlled to reduce light scattering, increase the brightness of front viewing and reduce side light pollution.

High-transparency substrate material: ultra-white glass or optical-grade acrylic with a transmittance of more than 92% is selected to ensure that the background is clearly visible. Huamite's patented nano-coating technology can also reduce surface reflections and enhance visual effects.

Driving and control technology

Transparent LED screens require special driving solutions to solve the problem of reduced supporting structures caused by high transmittance:

Distributed driving system: The driver IC is dispersed on the transparent substrate. The MatrixDrive technology developed by Huamite achieves high integration and concealment of the driving circuit.

Dynamic energy-saving control: Automatically adjust the brightness according to the ambient light. Huamite SmartBright technology can save up to 60% of energy consumption.

High-speed refresh rate: PWM dimming technology is used to ensure that the picture is flicker-free. Huamite products support 3840Hz ultra-high refresh rate to meet the needs of professional film and television shooting.

Structural design innovation

Modular design: Huamite transparent LED screen adopts standardized module design, supports front maintenance and quick disassembly and assembly, and the weight of a single module is controlled within 5kg, which is convenient for high-altitude installation.

Ultra-thin body: Through structural optimization, the thickness of the screen can be only 30mm. The thinnest part of Huamite Venus series is only 25mm, which hardly affects the original appearance of the building.

Seamless splicing technology: patented invisible seam solution to achieve seamless vision after multi-screen splicing. Huamite can provide a maximum of 1,000 square meters of continuous transparent display wall.

Main types and parameters of transparent LED screens

Classification by installation method

Classification by pixel pitch

Classification by pixel pitch
With the advancement of technology, the pixel pitch of transparent LED screens is constantly shrinking. The current mainstream products include:

P10-P20: suitable for large-scale displays viewed from a distance, with high light transmittance (85%-90%) and low cost.

P6-P8: balanced resolution and light transmittance (75%-85%), suitable for medium-sized commercial spaces.

P3-P5: high resolution, suitable for close viewing, with a light transmittance of 60%-75%.

P2.5 and below: Ultra-high-definition display, transmittance 50%-65%, mainly used for high-end applications.

Key performance parameters

Outstanding advantages of transparent LED screens

Revolution of visual experience

Display effect combining virtual and real: The unique display characteristics of transparent LED screens allow viewers to see the digital content on the screen and the physical scene behind it at the same time, creating an immersive visual experience. The transparent display solution created by Huamite for an international automobile brand perfectly combines new cars with dynamic special effects, which makes visitors amazed.

Unobstructed natural lighting: Compared with traditional LED screens, transparent LED screens can maintain a light transmittance of 70%-90% without affecting the original lighting structure of the building. A commercial complex project in which Huamite participated in the renovation achieved a shocking media facade effect while retaining the panoramic floor-to-ceiling windows.

Display effect suitable for both day and night: Maintain transparency during the day and transform into a gorgeous digital canvas at night. Huamite's intelligent light sensing system can automatically adjust the brightness to ensure the best display effect at any time.

Liberation of space and design

Does not occupy effective space: It is directly installed on the glass curtain wall or window, and almost does not occupy indoor space. Huamite's ultra-thin design keeps the screen thickness within 3cm.

Preserve the original aesthetics of the building: Add digital display functions without changing the appearance of the building, especially suitable for historical buildings or modern buildings with a strong sense of design. Huamite once provided customized transparent LED solutions for a century-old department store, perfectly preserving its classical facade.

Unlimited possibilities for creative design: It can be made into various arcs and special shapes. The spherical transparent LED device built by Huamite for a hotel in Dubai has become a new landmark in the city.
