In August 2025, Shenzhen Richarmony Technology Co., Ltd. (hereinafter referred to as "Richarmony Technology") officially disclosed a core patent entitled "Optical Consistency Adjustment Method for Seamless Multi-Screen Splicing Based on Glass Substrate" (Publication No. CN120428429A). By integrating dynamic optical correction and intelligent regional optimization algorithms, this technology successfully addresses long-standing industry pain points in large-size splicing displays, such as uneven brightness and color deviation. This milestone marks a major breakthrough for this national-level "Specialized, Refined, Characteristic, and Innovative" enterprise in the field of display optics.
Three-Pronged Technological Innovation Builds Core Competitiveness
As a high-tech enterprise specializing in display devices and smart hardware, Richarmony Technology’s newly disclosed patent integrates three innovative mechanisms—real-time sensing, dynamic correction, and regional optimization—demonstrating strong technological foresight:
- Dynamic Parameter Closed-Loop Adjustment System: High-precision optical sensors collect real-time core parameters of each display unit, including brightness, color temperature, and color gamut. Based on self-developed algorithms, the system automatically classifies units into reference and adjustment groups, achieving brightness correction with an accuracy of ±0.1 nit and color consistency control with ΔE < 1. This boosts calibration efficiency by over 50 times compared to traditional manual methods.
- Pixel-Level Optimization for Splicing Seams: To tackle the physical seam issue in multi-screen splicing, the technology innovatively introduces a "Gradient Weighting Algorithm." By identifying pixel coordinates in seam areas and configuring dynamic optical parameters, the visual width of seams is reduced from the traditional 0.5mm to less than 0.1mm, enabling a "near-seamless" display effect.
- Differentiated Optimization for Perceptual Zones: Leveraging human visual focus characteristics, the system divides the display screen into core perceptual zones and edge zones. It allocates 80% of optimization computing power to core zones while applying adaptive algorithms to edge zones. This design reduces system power consumption by 30% while maintaining visual experience, and has been adapted for scenarios such as in-vehicle displays and security monitoring.
Technology Layout Forms "Display + Intelligence" Dual Engines
This patent breakthrough is not an isolated innovation but a culmination of Richarmony Technology’s years of technical accumulation. Data from Qichacha shows that the company has accumulated 21 patents and 36 software copyrights, forming a technology matrix centered on display technology and extended to smart hardware:
In the in-vehicle display field, its "Display Optimization Method for In-Vehicle LCD Screens" has been put into mass production. Through ambient light adaptive adjustment technology, the in-vehicle screen’s contrast ratio is increased by 40% under strong light, and blue light suppression rate reaches 90% in night mode, supporting smart cockpit solutions for multiple automakers.
In industrial display scenarios, the glass-based small-pitch display control system based on AM driving technology supports 60Hz shadow-free display at 1024×768 resolution and has been applied to visualization terminals of semiconductor wafer inspection equipment.
"Technological innovation must target real-world scenario pain points," said the R&D director of Richarmony Technology. The multi-screen splicing technology has completed adaptation tests for scenarios including security command centers and in-vehicle multi-screen cockpits. Compared with similar solutions, it can reduce system deployment costs by 25% and lower post-maintenance frequency by 60%. Currently, the company has reached cooperation intentions with 3 industry clients.
Technology Breakthrough Path for "Specialized, Refined, Characteristic, and Innovative" Enterprises
Founded in 2018, Richarmony Technology has become a "Specialized, Refined, Characteristic, and Innovative Small and Medium-sized Enterprise" through continuous technological investment. Starting with display devices, the company has gradually expanded into integrated circuit design and intelligent in-vehicle equipment. In 2024, it added the "R&D of Electronic Special Materials" business segment, forming a vertical technology layout covering "materials-devices-systems." This strategy of deepening expertise in niche areas has helped it build unique advantages in the fierce market competition—by 2025, the gross profit margin of its core products reached 42%, 15 percentage points higher than the industry average.
Industry experts point out that with the rapid development of technologies such as AI large models and smart cockpits, display terminals are evolving from "passive output" to "intelligent interaction." Richarmony Technology’s technological breakthrough not only solves traditional display challenges but also provides a viable technical solution for next-generation intelligent display devices through the "optical adjustment + algorithm optimization" model, with promising market potential.
