From HDMI signal in, to LVDS signal out: 0.00054ms.
Back in 2016, I wrote a blog to provide some controller board latency test results (see https://www.digitalview.com/blog/latency-time-display/). The results are good, these are fast, low latency controller boards, but now we have a new model that is ultra fast…
The Digital View LLC-1920 is an HDMI in, LVDS out controller board for signal and panel resolutions up to 1920×1200. The latency of this board compared to a few other models is shown here:
- LLC-1920: 0.00054ms
- ALR-1920: 0.0186ms
- SVX-1920v3: 19.6ms
Measurement Method
The above measurements use an oscilloscope to measure the time from the HDMI signal input to the LVDS signal output, purely for the controller board, ie no panel.
Our normal method for measuring and stating the latency is to use a meter from Leo Bodnar, that sends a video signal to the controller board and then measures how long it takes to show on the LCD panel. So it will always give a longer latency figure than the oscilloscope method, the panel adds latency.
LLC-1920 Introduction
We haven’t formally launched this model so it is not listed on our website; the following is just a preview based on a few sample boards we made for testing and review.
- Input signal: HDMI
- Output signal to panel: LVDS
- Resolution up to 1920×1200
- Single panel support, input to out resolution matched
- Scaling: No
- OSD: No
- Backlight control: Yes
- Power input: 12V
If you have a project that needs this level of extremely low latency let us know.
