Using the above-noted standard, any color and brightness can be defined within the three-dimensional space with an L* number (white/black), an a* number (red/green), and a b* number (yellow/blue). In this instance, our main concern is going to be the b* value, which in simple terms can be considered as to how “blue” or “yellow” a particular color may be. The higher the number, the more yellow. The lower (negative) the number, the bluer.
The above-mentioned optical properties are of course the basic requirements of LOCA adhesives. The next challenge is to be certain that these optical qualities will be retained and consistent over time under real-world operating conditions. It is in this regard that b* number becomes a useful tool. The b* number is especially important in its consistency over time as yellowing of screens is considered highly undesirable and indicative of aging or failure in the eyes of consumers.
Many environmental conditions have been shown in the past to lead to a yellowing of LOCA materials over time and a corresponding deterioration in image quality. By measuring the CIELAB coordinates of a given device after initial manufacture, it is then possible to expose the device to harsh conditions and measure any changes in CIELAB numbers.
Each of these tests and all of them combined is designed to simulate years of real-world aging in environments such as in automobiles and appliances. By showing consistency over time under these conditions of the b* value, manufacturers can be confident of resistance to yellowing for LCD displays. In addition, customized testing is not uncommon in cases where a product may be exposed to unique or especially harsh conditions.

If you"ve dwelled/lurked on the forums for a reasonable amount of time or have kept up with news covering the OnePlus One, you should already be aware of the infamous "yellow tint/band/gradient/piss/screen/tinge" (how many terms have been coined for this phenomenon?). If not, basically, it"s an issue that has evidently plagued some* OnePlus Ones.
Some OnePlus Ones are affected to different extents, but most are unaffectedI"m in the third camp. Mine has shown the tiniest bit of tint since day one (bottom 1/10th of the screen, more visible when looking down from above), remained unchanged after a month of owning it, and to this day remains unchanged as of yesterday (17th December 2014).
When displaying a prominently white screen/image/webpage, there is a visible yellow "tint" (let"s just call it a tint for now) at the bottom of the screen that"s "yellow-er" than the rest of the screen, right above where the capacitive buttons are. It is also the edge where the backlight LEDs are situated. Now, its severity depends from case to case, and often it doesn"t really affect functionality,
The former aforementioned thread addresses an "overall yellowish hue", and details how OnePlus sources panels from JDI, different factories have different batches, different screen temperatures, other flagship phones also suffer from this yadayada...and the latter aforementioned thread lines up the One with other phones and is seemingly normal.
this issue doesn"t exist. People have RMA"ed their yellow tinted One (success? failure?), others who have purchased multiple Ones have the tint on all of them (at different extents), and some other stuff. I couldn"t keep track of it all.
Another thing to consider when seeing photos of the yellow band problem is that a lot of the photos were taken at extreme angles with Contrast and Levels changed for more visibility. We have been able to replicate some of the pictures posted here by playing with the Levels settings in Photoshop and ...
Screenshots and screencasts taken on my Macbook Air (Sierra 10.12.2) have a yellowish tint to them which doesn"t match the actual display output on the screen itself. It"s very odd.
...and here"s some screenshot-ception to show that the screenshot is yellower than the thing it"s of and how screenshots within screenshots get progressively yellower:
Changing my display profile changes the appearance on the screen quite a lot, but barely changes the yellowness of the screenshots. These three all looked very different when I took the screenshots (the last one was almost blue), but the screenshots are all almost the same yellow:
With the last one selected, Adobe RGB, all the screenshots look okay on my screen, but everything else looks tinted blue and they still look yellow to everyone else.
This code should work, however my Diymall .96 Yellow and Blue OLED LCD did not come with a backlight that worked. The address in the WireTransmission line might be different than what is below.
I"m in IT and I find this feature ridiculous, even for security purposes. This feature does not indicate that an app is recording, (as your statement would indicate), only that an app MAY be recording - it shows up immediately once a window has been selected for recording purposes. This feature should be user controlled, even if you have to add password controls to it for security. A user shouldn"t have to be subjected to this while recording their own screen anyway. One window with a yellow border is bad enough. Try adding a bunch of windows with yellow borders. Then where does that leave you? Especially since the borders aren"t actually indicating that the windows are being recorded, only selected. So it"s not even a good tracking system. It only serves its purpose when a hacker shows up, but not for normal every day use.
