Let me add some info above what was said by AKDrone about the TripleTek 8 Pro.
After buying my
Mavic 3 in January 2022 I was faced with a decision to either pay more for the RCPro with an integral bright display or buy the TriplTek Pro 8 which was 8” diagonal and an advertised luminance of 1200 nits. When DJI didn’t initially offer waypoints I decided to go for the TriplTek since I was feeling that it was more likely to support Litchi, not ever imagining that DJI would decide later to not release the SDK for the
M3.
The TriplTek has some key advantages: large 8” screen and lots more brightness than my current iPhone XR screen. It has very nice battery life. The downside is that it weighs a hefty 698 gms (24.6oz) with their metal bracket attached for mounting it. That is nearly 3X the weight of a DJI Mini! As a result, it is very top-heavy when used with the RCN1 so you need a special mount and a lanyard to use this.
While is a great size and noticeably bright it isn’t bright enough to totally compete with the sun on a bright sunny day. That would require 2500 nits per many industry experts. What is worse, the unit I have has an average white on-axis luminance of only about 950 nits, well short of the advertised 1200 nits. I am not sure if this is typical.
The electronic display industry standard for measuring luminance is published by the Society for Information Display (SID) and is called the International Display Measurement Standard (IDMS). Section 5.3 defines the method for measuring luminance which consists of measuring on axis with a standard luminance meter with maximum amount of red+green+blue applied to get the highest level of white luminance. It is stated that one should use a frustrum tube to ensure that ambient light is not striking the portion of the screen being measured. One should sample at least 50 pixels of the display. Section 5.5.1 defines the measurement of the average peak white level by stating that at least 5 points need to be measured for luminance and then averaged.
When a manufacturer specifies the brightness of a display the quantitative spec means the average white luminance. Most display module manufacturers warranty that number to within 10% but do that to ensure that the worst-case sample exceeds that advertised value for luminance.
I brought my TriplTek 8 Pro to a colleague of mine who as a consultant has a display metrology lab. With the TripleTek set to 100% brightness he measured a fully white screen at the center of my tablet using a Topcon BM<-9A, an instrument that sells for about $2500 and is well known in the display industry. The brightest that we were able to measure was 1095 nits at the center, but other regions measured as low as 824 and many measured in the neighborhood of 950 nits. A 5-spot measurement averaged 938 nits or 262n nits short of the 1200 nit spec.
With this finding I returned it to TripleTek for evaluation. They tested it and then wrote,
“We tested your display with a clear white screen indoors, the display is over 1100 nits in most areas. and under direct sun conditions is well over 1200. The test must be done in a lab with a particular white test color screen to be able to determinate the real brightness’ They included this photo of their test. Notice that their meter reads 1065, so if it was over 1100 nits most places one would have thought they would have shown that. Clearly, they don’t understand the need to isolate the measurement from ambient brightness, as indicated in their statement. I asked to speak with one of their metrology engineers, but nobody bothered to reach out to me.
When this tablet was returned to me, I had it measured again with the Topcon and the measurements were a repeat of what was measured before. I stand by my statement that this unit has an average peak luminance of 950 nits or less. To be fair I only measured this one tablet and perhaps mine was below par for what they ship, but I am sharing this so that others will be aware of this possible discrepancy.
I will add that just because it is about 25% shy of spec, that doesn’t mean that it will appear 25% less bright since the eye has logarithmic response to luminance. It still is far brighter than any other tablet I have used. Apple claims that the new iPhone Pro 14 can run at 1200 nits and it probably will, but it isn’t so nice and large as this display. If the Pro controller is really 800 nits it won’t look that much dimmer than the TriplTek and it is certainly smaller diagonal, albeit much more convenient to set up and use. The other good thing about the TripleTek is that it produces this brightness without the use of any fan. A friend of mine with a high brightness
CrystalSky added a fan to his to ensure that it didn’t overheat.
In short, I plan to continue to use my TriplTek 8 Pro because it is the best option now for a large bright display, but it isn't everything that their advertising would suggest.
