Lehman Optoelectronics: The road to intellectual property rights protection and the light of COB tec

In the LED display industry, where technological competition is increasingly fierce, intellectual property rights are like the core weapon and development lifeline of enterprises. Lehman Optoelectronics, as the pioneer defender of the series of patents on pixel engine technology in the industry, is firmly at the forefront of rights protection and launching a key battle to defend its innovation achievements and legitimate rights and interests.
Relying on years of unremitting cultivation and innovative exploration in the field of technology research and development, Lehman Optoelectronics has successfully built"" a series of forward-looking and breakthrough patent systems covering pixel engine (also known as virtual pixels and dynamic pixels) technology. These patent achievements are not only a strong witness to Lehman Optoelectronics 'technical strength, but also an important cornerstone for promoting the development process of the entire COB display technology. However, in the wave of market competition, suspected infringements by some companies have quietly surfaced like a haze, posing a severe challenge to Lehman Optoelectronics's innovation achievements.

On November 23, 2024, at the LED Display Industry Forum that gathered industry wisdom and attention, the pixel arrangement of the flip-chip Mini COB dynamic subpixel display product exhibited by a company was actually similar to that of Lehman Optoelectronics '" pixel engine" display technology patents present a surprisingly high degree of similarity. This phenomenon is like a stone thrown into a calm lake, instantly arousing thousands of waves in the industry. Lehman Optoelectronics was keenly aware of this potential infringement and acted quickly without hesitation, sending a warning letter to the company as soon as possible to avoid infringement disputes. This move not only demonstrates Lehman Optoelectronics 'determination and courage to resolutely safeguard its intellectual property rights, but also sounds like a wake-up call in the industry to respect innovation and protect intellectual property rights.
Lehman Optoelectronics has always regarded the accumulation and improvement of intellectual property rights as the top priority of its corporate development strategy. In recent years, it has continuously increased its investment in patent technology research and development, continued to apply for a number of pixel arrangement patents and COB packaging patents, and carefully woven a strict patent pool covering multiple fields such as pixel arrangement and packaging technology. Whether it is a series of technology clusters such as RGB triangle arrangement, six-lamp virtual pixel technology, or RGBG rectangular arrangement and four-lamp virtual pixel technology, they have become Lehman Optoelectronics 'core competitiveness in the field of COB display products and are widely used in many of its COB display products that are popular in the market.
Lehman Optoelectronics knows that in this battle to defend intellectual property rights, its significance goes far beyond the company's own interests. It is related to whether the healthy development ecology of the entire COB display industry can be well maintained, and whether the fire of innovation can continue to burn in the industry and shine more brilliantly. Therefore, while resolutely defending its intellectual property rights and legitimate rights and interests, Lehman Optoelectronics actively calls on its peers to join hands with its responsibility and mind as an industry leader. Work together to create a good industry development atmosphere full of respect and awe for intellectual property rights and cherishing the innovative achievements of others, so that every company's innovative efforts can receive due protection and reward, thereby promoting the entire LED display industry on the road of innovation. Move forward steadily and move towards a more brilliant future. Only in this way can the entire industry achieve sustainable high-quality development on the basis of respecting innovation and protecting intellectual property rights, contribute more wisdom and strength to global scientific and technological progress, and write its own magnificent chapter in the wave of the digital age.

Virtual pixels, also known as shared pixels or dynamic pixels, are a widely used technology in the display field. The following is a detailed introduction of virtual pixels:

Definitions and principles

• Concept: Virtual pixels refer to the relationship between the number of physical pixels on the display and the number of pixels actually displayed is 1:n (n=2x2, etc.), that is, there are more image pixels that can be displayed than the actual pixels on the display. The common ones are the length and width pixels are 2 times each. For example, a light board configured by 2 red, 1 green and 1 blue. If it is a 35-dot matrix of real pixels, the virtual effect will become 59 dot matrix 1.
• Principle: The dots of virtual pixels are scattered, and their luminous points are between the tubes. The red, green and blue display components of each point in the display unit are evenly distributed to match the color mixing effect of the pixels. The representative color of the virtual display point is composed of the color mixing of adjacent red, green and blue pixels. Through calculations by the display control system and the like, pixels several times larger than the physical pixels can be quickly sent to the physical pixels for display multiple times in parity columns and parity rows, thereby realizing the virtual pixel effect 1.

Implementation methods and common solutions

• Implementation method: The implementation of virtual pixels requires a specific pixel arrangement method and control algorithm. Taking the 4-multiplication scheme as an example, pixels 4 times the size of physical pixels are quickly sent to the physical pixels for display in 4 times according to odd and even columns and odd rows. The effect is equivalent to reducing the spacing by 50%, achieving the original 4 times resolution.
• Common solutions: Common virtual pixel solutions include rgbg solutions and rgb solutions in different placement positions, such as rgb three-lamp virtual, rgbg four-lamp virtual, etc. 1.

advantages

• Improve display performance: With the same number of lamps, virtual pixel display is equivalent to four times the effect of real pixel display, which can effectively improve the clarity and delicacy of the image and provide users with more realistic and clear visual enjoyment. 12.
• Reduce costs: Using a large virtual pixel screen can reduce the use of one-quarter of the lamp tubes at the same resolution, and can achieve the same visual effect as many real pixels, thereby greatly reducing the cost of the entire screen and making LED display The screen is cost-competitive in more application scenarios, promoting its popularity in the commercial and home display markets. 12.
• Improve the viewing experience: Since virtual pixel technology can make the luminous dots more evenly distributed, the more uniform the luminous light is under the same area, the lower the fatigue a person will feel when watching. 1.

limitations

• Physical limitations of display effect: The actual display effect of virtual pixel technology will deteriorate as the virtual multiple increases. At near-eye viewing distance, the picture may appear grainy, especially static text, and jagged around it. 2.
• High requirements on production process and technical level: Virtual pixel technology requires higher production process and technical level to achieve, which may increase production costs and production difficulty 2.
• No advantage in solid color display: Virtual pixels display the same effect as real pixel display when displaying pure red, pure green and pure blue. They only have an advantage when displaying mixed colors, while in reality, there is relatively less solid color content displayed 1
