LED Display Refresh Rate: 3840Hz, 7680Hz and 15360Hz Explained

Refresh rate is a commonly requested LED display specification, but it is not the same as the video frame rate or the number of rows scanned. A larger refresh-rate number can be relevant to how LED pixels are driven and recorded by a camera; it does not establish picture quality or camera compatibility by itself.

What is LED refresh rate?

On a multiplexed LED module, the driver electronics repeatedly update light output across pixels as video images are displayed. The stated refresh rate generally relates to that drive cycle. The exact measurement convention may depend on the driving system, so obtain the manufacturer specification and test method.

Refresh rate vs frame rate vs scan rate

Video frame rate describes how many distinct video frames are supplied each second. Scan ratio describes multiplexing across LED rows or groups. Refresh rate describes a different aspect of LED driving. A 3840Hz display does not accept 3840 unique video frames per second simply because that number appears on its datasheet.

Why the driver IC and receiving system matter

The underlying LED driver IC, scan architecture, receiving system and driving settings can influence the achievable refresh rate. Typical engineering searches include LED driver families from Macroblock (for example MBI5253 and MBI5264), Chipone and other vendors. This guide does not assign a particular IC to every JYVISIONS product; model-specific specifications belong in a dedicated driver IC guide or verified project description.

How LED refresh rate affects image performance

The values 1920Hz, 3840Hz and 7680Hz frequently appear in procurement comparisons. Their relevance varies with content, brightness and the camera or viewing setup. Check the product setting that achieves each value, whether grayscale tradeoffs occur and how the final system will be tested.

Camera flicker and banding

Camera exposure, shutter angle, rolling shutter, camera frame rate and LED drive timing interact. High stated LED refresh may reduce some visible artifacts in certain setups, but it cannot guarantee that a camera will never capture bands. Test the actual camera and screen configuration at the target brightness and shooting settings.

Priority product examples: Jade COB and DC Series

Jade COB and DC Series are the primary JYVISIONS product references. Jade COB offers 3,840Hz, 7,680Hz and 15,360Hz refresh configurations; DC offers 3,840Hz and 7,680Hz. The options depend on the final product configuration, not on a single driver IC specified in this Knowledge guide.

Procurement and acceptance checklist

Ask for operating refresh configuration, actual scan ratio, compatible video input formats, camera test plan, brightness range and the acceptance criteria. Request video evidence from the relevant installation environment rather than depending on one datasheet line.

Frequently Asked Questions

No. LED refresh rate and content frame rate describe different operations.
No. Camera exposure timing, brightness and full LED driving configuration can still create artifacts.
No. Scan ratio relates to row or group multiplexing, while refresh rate concerns repeated driving updates.

Factory-confirmed Jade COB and DC refresh options

Jade COB offers refresh options of 3,840Hz, 7,680Hz and 15,360Hz; DC Series offers 3,840Hz and 7,680Hz.

Actual achievable settings depend on the selected screen configuration. Related LED driver ecosystems include Macroblock MBI5253 and MBI5264 and Chipone families as examples of searchable driving technologies; model mention is not a claim these devices power every Jade or DC configuration.

Why the measured image still matters

A high refresh-rate specification by itself does not prove a flicker-free recording under every shutter, exposure, brightness or scan setting. For camera-critical jobs, ask for a recording or acceptance test using the final driving configuration.
