Difference And Function Of 1920hz And 3840hz Led Video Wall

1) For 1920Hz Led Video Wall Displays:

①The display is generally smooth, but slight ghosting or blurring may occur when displaying fast moving scenes.

②When shooting with a mobile phone or camcorder, water ripples, moiré patterns and flickering stripes are more likely to appear.

③While the visual comfort level is sufficient for daily viewing needs, prolonged viewing or exposure to rapidly changing images may more easily cause eye strain.

④The technical principle typically employs a dual latch driver IC, which is relatively inexpensive and offers high cost effectiveness.

⑤Main application scenarios general display occasions such as regular indoor meetings, information dissemination, classrooms, and shopping malls, where there are no special requirements for shooting.

2）For 3840Hz Led Video Wall Displays:

①The display effect is more stable, clearer, and smoother in dynamic scenes, accurately capturing details of fast moving objects.

②The shooting effect effectively avoids water ripples and flickering during shooting, resulting in cleaner and clearer images.

③A higher refresh rate helps reduce eye strain during prolonged viewing, making viewing more comfortable.

④The technical principle requires the use of a high definition, high-order PWM driver IC, such as the FT7780 solution, which is significantly more expensive due to its complexity.

⑤Main application scenarios stage performances, sports broadcasts, high end commercial advertising, virtual filming XR, and occasions requiring filming with professional equipment.

3）For 1920Hz Led Video Wall Display Features:

①Its smoothness far surpasses earlier conventional refresh rates, such as 960Hz and below 1920Hz, for the human eye, viewing most dynamic content, such as videos and PPT animations, is already very smooth.

②Without using a camera to capture the footage, the average viewer would have virtually no way of perceiving the difference in smoothness compared to higher refresh rates, such as 3840Hz.

③With mature technology and a complete industry chain, it is currently the mainstream and most cost effective choice in the market, it achieves the best balance between meeting basic display requirements and controlling the budget.

④Suitable for most occasions that do not require professional photography, such as: indoor conference rooms, classrooms, shopping mall information screens, most outdoor advertising screens, data monitoring centers, etc.

⑤Its biggest characteristic, and also its limitation, is that it cannot perfectly handle all camera devices. With electronic shutters from mobile phones and camcorders, it is prone to producing wavy scan lines and flickering, making it unsuitable for situations requiring recording or live streaming.

4）For 3840Hz Led Video Wall Display Features:

①This is its most prominent and irreplaceable feature, it can almost completely eliminate water ripples and flickering under the shutter speeds of various cameras and mobile phones, ensuring clean and stable footage, this is why television stations, film and television productions, and large scale live broadcasts must adopt this standard.

②Achieving a 3840Hz high refresh rate is not simply a matter of increasing parameters, it relies on high end PWM driver ICs, such as the Macroblock MBI series and Chipone ICND series and more complex scanning algorithms, representing a higher level of technology and stability.

③While the human eye perceives only a limited improvement in smoothness above 1920Hz, 3840Hz theoretically provides more stable and sharper image edges and reduces extremely subtle ghosting when displaying very fast-moving scenes, such as slow motion replays of racing cars or sports games.

④Due to its technological costs and core positioning as a shooting service, it is mainly used in high-end scenarios with rigid shooting needs or sufficient budgets, such as broadcast and television studios, concert or gala stage backgrounds, e-sports event main screens, high-end brand launches, and virtual XR shooting studios.

5）How to choose 1920Hz and 3840Hz Led Video Wall Display based on the venue scenario:

①Choosing 1920Hz if your screen is primarily used for human viewing and will not be frequently photographed, such as in corporate conference rooms, showrooms, shopping mall information screens, and most indoor and outdoor advertising screens, 1920Hz is a perfectly adequate and cost effective choice.

②Choose 3840Hz if your screen will be used for filming or live streaming by mobile phones, cameras, or other devices, or if you have extremely high requirements for dynamic image quality, such as in TV studios, concerts, e-sports events, or high-end product launches, then you must choose a product with a refresh rate of 3840Hz or higher to avoid water ripples and ensure shooting quality.
