Analysis of the influence of the increase of pixel density of small-pitch LED display。

With the development of display technology, the pixel density of small-pitch LED displays has been continuously increasing, and products with a pitch of less than P1.0 have now become the mainstream in the market. This technological evolution brings multiple impacts, which are worth in-depth understanding by industry practitioners.

Significant improvement in display performance

The most direct advantage of high pixel density is the improvement in resolution. Taking the 4K standard as an example, a P1.2 screen only requires 6 square meters to achieve it, while a traditional P2.5 screen needs 21 square meters. The formula for the optimal viewing distance has also changed, from the traditional "pitch (mm) × 3" to "pitch × 1.5".

In terms of color performance, the miniaturization of LED chips reduces the light-emitting area by 30-50%, significantly improving the uniformity of single-pixel brightness. At the same time, the proportion of black matrix is reduced, increasing the contrast by 20-30%, and the color gamut coverage can reach 98% of DCI-P3.

Technical challenges multiply

As pixel density increases, heat dissipation issues become increasingly prominent. The heat flux density of a P1.2 screen reaches 3.5 W/cm², which is more than four times that of a P2.5 screen, requiring new technologies such as micro-channel heat dissipation to address the problem.

The complexity of the driving system also increases significantly. A P1.0 screen requires a driving IC to support a pad pitch of ≤0.1mm, and the number of output channels increases from 48 to 256 channels per chip. The proportion of static power consumption rises from 20% to 60%, posing higher requirements for power management.

Controlling the yield rate becomes more difficult. Due to the square growth in the number of pixels, under the same single-point failure rate, the yield rate of a P0.7 screen is 40-50% lower than that of a P1.8 screen, requiring more precise manufacturing processes.

Innovations in application scenarios

High-density displays are opening up new application fields. In the AR/VR field, a pixel density of over 150 PPI is required; in virtual shooting, the moiré pattern occurrence rate can be reduced to 1/5 of that of traditional screens, and the camera's close-up distance can reach 0.5 meters.

Traditional scenarios have also been upgraded. The optimal viewing distance in meeting rooms has been shortened from 3 meters to 0.8 meters, and the readability of text has increased by 300%. However, the cost issue still needs attention. The cost of a P0.9 screen is 80% higher than that of a P1.2 screen, and that of a P0.6 screen is 220% higher.

Industry practice: Enbon R5 series leads the technological frontier

In the wave of pixel density upgrades, Enbon's R5 series of small-pitch LED displays, with its outstanding performance, has become an industry benchmark. This series covers four types of small-pitch products with pixel pitches of P1.25, P1.56, P2.604, and P2.976, precisely covering the diverse needs from high-end commercial to civilian markets:

• P1.25: With an ultra-high pixel density (about 800 PPI), it creates ultimate clarity and is suitable for scenarios with strict requirements for image quality, such as command centers and studios;

• P1.56: Balancing performance and cost, it is the preferred choice for mid-range markets such as meeting rooms and exhibition displays;

• P2.604/P2.976: With larger pixel pitches, it offers more economical solutions and is widely used in outdoor advertising and sports venues where viewing is from a distance.

The Enbon R5 series effectively solves the process, cost, and maintenance problems brought about by high pixel density through modular design, intelligent correction algorithms, and efficient heat dissipation technology, providing a practical reference for the industry. In the future, Enbon will continue to focus on technological innovation, driving small-pitch LED displays towards higher pixel density and better user experience.
