Lehman Cold Screen Master: Three technologies lead LED micro-spacing into the era of low-consumption

As digital scenarios continue to expand, the LED display industry is experiencing a qualitative breakthrough from large spacing to micro spacing. According to Dixian's data for the first half of 2025, sales of P1.1-1.4 small-pitch products increased by 34.7% year-on-year, and products below P1.0 increased by 12.7%. The industry has officially broken through the P1.0mm technical boundary, leapfrogging towards P0.9mm and smaller pitch, and fully entering the era of micro-pitch. At the same time, the tightening of global ESG standards has made energy consumption a core competitiveness indicator of products. The pain points of traditional LEDs with small spacing, high power consumption and high temperature have become increasingly prominent. In this context, Lehman Optoelectronics launched the HD King Cold Screen Master (P0.9mm), which triggered an energy efficiency revolution with three key technological innovations. It not only solved the industry's pain points, but also promoted the leapfrog development of LED micro-spacing from the bottom of the technology. Redefine the competitiveness standards for micro-spacing display products.​

Industry pain points: Energy consumption and temperature dilemma

In the process of advancing from the micro spacing of LEDs to the smaller spacing, the high power consumption and high temperature problems of traditional products have gradually become the biggest obstacle to the implementation of scenes. Data shows that the power of traditional LED small-pitch displays is about 300W/㎡. High energy consumption not only drives up the long-term use cost of users, but also causes the temperature of the screen to continue to rise, causing a series of chain problems:

In close-range scenarios such as conferences and education, high temperature on the screen will cause obvious thermal interference, which will affect the comfort of participants and learners. Especially in confined spaces in summer, it may even cause discomfort such as dizziness and irritability, reducing communication and learning efficiency; In 24-hour operation scenarios such as command and monitoring and data centers, high temperature will accelerate the aging of screen components, shorten the service life of equipment, and increase the risk of system downtime. Once the display terminal fails, command and dispatch interruption and data monitoring failure may occur, causing serious losses; Even in non-long-term operation scenarios such as commercial displays, high energy consumption will put users under the dual pressure of early procurement costs + later operation and maintenance costs, restricting the penetration of LED micro-spacing into the wider market.​

The core of these pain points is that traditional products fail to balance the relationship between high-precision display with low-energy temperature control. To ensure ultra-high-definition image quality, continuous high-power operation is often required, which in turn leads to temperature rise. The technological innovation of Lehman HD Wang Lengping Master (P0.9mm) starts from this core contradiction and builds the dual advantages of low power consumption + low temperature through the synergy of three technologies.​

Technological breakthrough: Three core innovations, building cold screen technical barriers

The energy efficiency revolution of Lehman HD Wang Lengping Master (P0.9mm) is not a breakthrough in a single technology, but a collaborative innovation of AI algorithm + hardware optimization + display technology. The three core technologies solve energy consumption and temperature issues from different dimensions, forming a difficult to replicate technical barrier:

1. AI low-power smart display technology: dynamic balance

Different from the traditional simple idea of sacrificing image quality for energy conservation, Lehman's AI low-power smart display technology uses intelligent algorithms to dynamically optimize energy consumption allocation to achieve non-discount image quality and optimization of energy consumption. This technology analyzes the light and dark distribution and dynamic changes of the display content in real time. For example, when displaying dark field pictures (such as night scenes, dark PPT), the energy output of non-highlighted areas is automatically reduced; when displaying static content (such as text documents, data tables), unnecessary power consumption is reduced; and when displaying highly dynamic pictures (such as videos, animations), energy is accurately allocated to ensure screen smoothness and color reproduction.​

This on-demand power supply mode allows the screen to maintain optimal energy efficiency in different scenarios. Test data shows that when playing static PPT in conference scenes, AI low-power smart display technology can reduce energy consumption by more than 30%; when playing dynamic video, energy consumption can also be reduced by 15%-20%, and there is no image quality throughout the process. Loss, perfectly balances display effects and energy-saving needs.​

2. Ultra-precise voltage control technology: Reduce energy consumption and heat from the source

If the AI algorithm is dynamically adjusted, then ultra-precise voltage control technology achieves source energy conservation from the bottom of the hardware. This technology carries out a special power supply design for RGB chips, the core component of LED display. By accurately matching the voltage requirements of different chips, it avoids power loss caused by excess voltage in traditional power supply methods.​

Traditional LED displays use unified voltage power supply. In order to adapt to the highest power chips, it is often necessary to provide a voltage higher than the requirements of most chips. Excess electricity will be converted into heat dissipation, which both wastes energy and increases temperature control pressure. Lehman's ultra-precise voltage control technology allows each RGB chip to operate at the optimal voltage by subdividing chip models and dynamically adjusting the power supply voltage, greatly improving power utilization. Data shows that this technology reduces power consumption by 50% compared with traditional power supply methods, and at the same time reduces heat generation from the source, allowing the screen temperature to be fundamentally controlled, achieving the dual benefits of energy conservation and temperature control.​

3. Low-black lossless direct display technology: synergy

While solving the energy consumption problem, Lehman did not ignore the core image quality requirements of micro-pitch display. The bottom-black lossless direct display technology optimizes the screen structure to improve the quality of the picture and further assists in temperature control of the screen. This technology uses a special screen bottom design to achieve the dual characteristics of high surface blackness and 100% light transmittance:

High surface blackness can significantly improve the contrast of the picture, making black purer and more vivid. When displaying text, the edge of the writing is sharper; when displaying images, the level of detail is richer; and 100% light transmittance avoids the traditional screen The underlying material blocks and absorbs light, reducing ineffective energy loss. It is worth noting that the improvement in light transmittance not only optimizes the image quality, but also makes the heat inside the screen easier to dissipate. Combined with the source heat reduction of ultra-precise voltage control technology, a dual guarantee of heat control + heat dissipation is formed, making the cold screen more stable.​

Scene landing: comprehensive break

The synergy of the three technologies has enabled Lehman HD King Cold Screen Master (P0.9mm) to achieve a revolutionary breakthrough: the power consumption of the product is only half of that of the traditional LED small-pitch display screen, and the screen temperature is lower than the human body temperature, becoming a veritable cold screen. This breakthrough not only directly solves the core pain points of traditional products, but also clears the obstacles for the landing of LED micro-spacing from three dimensions: scene adaptation, cost control and market penetration:

In the command and monitoring scenario, the 24-hour low power consumption operation greatly reduces the system operation and maintenance cost. Calculated according to the daily operation of single screen for 24 hours and the electricity price of 0.6 yuan/kWh, the electricity charge can be saved by more than 1000 yuan every year; meanwhile, the low temperature operation reduces the aging speed of components, prolongs the service life of equipment by more than 30%, reduces the replacement cost and downtime risk, and ensures the stability of command and dispatching.​

In commercial conference scenarios, the cold screen feature completely eliminates thermal interference. Even in a closed conference room in summer, there is no obvious heat feeling near the screen. Participants can watch the screen up close for a long time, improving communication efficiency;AI has low power consumption Smart display technology adapts to different meeting content and automatically saves energy when playing PPT, and ensures smoothness when playing videos, meeting diverse meeting needs.​

In home theater scenarios, low power consumption reduces long-term use costs for ordinary home users, allowing LED micro-spacing to approach civilian consumer goods from professional-grade equipment; the high-precision display of P0.9mm combined with high contrast image quality can create an immersive viewing experience, while the low-temperature characteristics avoid the noise + heat dissipation problems of traditional projection equipment and improve home entertainment comfort.​

More importantly, Lehman's technological innovation has formed a deep synergy with the development direction of ultra-high definition of LED micro-spacing. Currently, a 163-inch screen requires a P0.94mm pitch for 4K resolution, and a P0.47mm pitch for 8K resolution. Lehman has achieved mass production of P0.47mm products, laying the foundation for the implementation of ultra-high-definition displays. Ultra-high-definition displays require higher hardware performance. If energy consumption is not well controlled, it may easily lead to a sharp increase in equipment operating pressure. Lehman's energy efficiency technology just solves this contradiction: AI low-power smart display technology ensures that ultra-high-definition image quality does not rely on high energy consumption, ultra-precise voltage control technology avoids heat accumulation during ultra-high-definition operation, and bottom-black lossless direct display technology improves the texture of the picture while reducing losses, making ultra-high-definition + low energy consumption possible, and promotes the LED micro-spacing to truly move from breakthrough in technical parameters to practical implementation in all scenarios.​

Industry impact: Leading micro-spacing display into the era of energy efficiency competition

The launch of Lehman HD King Cold Screen Master (P0.9mm) is not only an innovation of a product, but also has a profound impact on the LED micro-spacing industry:

From the perspective of competition standards, it incorporates energy consumption and temperature control into the core evaluation system of micro-spacing products, breaking the previous single competition pattern of point-spacing theory. In the future, when users choose micro-pitch products, they will not only pay attention to the dot spacing size and image quality, but also pay attention to energy consumption levels and temperature control capabilities. This will force industry companies to increase research and development of energy efficiency technologies and promote the overall technical level. upgrade.​
