Since the creation of the first electric television (dating back to around 1927), society has fully embraced these screens. The first television sets were black and white pictures and this is one technological device that has completely transformed rapidly throughout the years. Nowadays, there are tv sets with resolutions up to 8K which provide clear and bright pictures that are insanely realistic! With such advancements, it is crucial to know how their brightness can be effected.
So with this in mind, do TVs lose brightness over time?
In order to assess if TV's lose brightness over time, it is important to realize that this refers to a television set's lifespan. The term lifespan shouldn't alarm anyone, it only means the TV's brightness will be effected after a certain amount of time.
This measurement is calculated by hours.
After a certain amount of hours, the brightness on television will be affected. In fact, when this point is reached, the television is considered to have lost half of its brightness capacity. That is an awful lot! This certainly doesn't make the tv unwatchable, but it does make it less bright to do so! To determine just how many hours that is varies from one tv type to another.
The brand of tv does not matter when it comes to whether or not it loses brightness. All tvs will eventually lose their shimmering brightness. This is a harsh fact and it has been reported that newer tvs with brighter screens to start will have a shorter "lifespan".
This could be to say that older television sets were the way to go because of their brightness lasting a bit longer, but we're all spoiled with the wondrous colors and picture quality that comes with these new-age modern tvs.
To really dive even further into tvs losing their brightness over time, knowing how their brightness works is a key component. When we notice a difference in picture quality, we assume adjusting the brightness is how to remedy the problem.
This can naive move can be due to the television losing its brightness as per its lifespan or just because we think it is not as bright. What is the major difference between brightness and backlight?
Brightness refers to the color of the pixels on the screen, the backlight actually refers to the light behind the physical screen that is projected to the screen.
It is recommended that in order to extend the brightness life of tv that turning the backlight down is the key over adjusting the brightness. But to really get a good grip on the brightness factor, knowing how tv works helps put the brightness in perspective! (Quite literally!).
Tvs are comprised of 4 main parts, which considering what they are able to achieve for us is truly amazing! These main components are phosphors, steering coils, anodes, a cathode ray tube.
The job of each one contributes to how the tv works and more specifically, the anodes and phosphors help with the picture display.
The phosphors can be any material that is exposed to radiation and emits light. This radiation can be emitted by ultraviolet light or beams of electrons. These are directly related to the cathode ray tube as the phosphor is layered on the screen and then receives the electron beam producing a glow.
This applies to color tv by having three phosphors with three electron beams. The phosphor layers are red, green and blue in this case and the electron beams bridge the gap providing any other color combination.
When it comes to the anodes, these are the pathway for electrons to travel to the tv screen. They are placed directly between the cathode ray tube and the tv screen. The anodes speed up the electrons to project them onto the tv by condensing them tightly.
The cathode ray tube is a heated filament. This particular part of the tv has similarities to a light bulb and is generally placed in a vacuum that is in a glass tube. From this point, the heated element projects the electrons through the vacuum portion of this configuration.
The steering coils are copper and do as their name implies, "steer". They aid in getting the electron beam where it needs to go. More plainly put, the coils are doing this through the power of a magnetic field. There are usually two of them in a tv set that helps these beams be directly both horizontally and vertically towards the screen.
What does this all have to do with tvs losing their brightness? The components above make for a fascinating piece of technology that creates these wonderful colorful screens to watch.
With that said, remember that brightness refers to the colored pixels on a tv screen and the backlight is the process going on behind the screen! So how the tv works shows how the screen creates the pixels that give us the brightness we experience.
Do LED TVs Lose Brightness Over Time?
Like all tvs, LED tvs do lose brightness over time, just at a different rate than other tv types. LED tvs are known to last for approximately up to 60,000 hours which equates to about 7 years. This is about average when looking at other tv types. However, overall, LED tvs will become less bright over time than their competitor tv types.
The debate of the exact amount of hours a tv will uphold its brightness argues that the average range is 60,000 hours up to around 100,000. LED tvs are supposed to be the best out there, but the hours ticking away in them have shown to be around 60,000 on average. It has been claimed that they could last upwards of 80,000 hours based on the brand. But the brand is not always directly related to the hours in a tv brightness lifespan.
LED in tech terms mean "light-emitting diode". This specifically refers to the bulb type in the backlight of the TV. So in LED tv, the bulbs in the backlights are LED rather than the traditional type of bulbs that use cathode fluorescent lamps (or CCFL).
While LED items are considered to be more energy-efficient, this becomes problematic as the backlight in these tv types will not last as long. This creates more problems on top of the brightness being effected on its own.
Do Plasma TVs Lose Brightness Over Time?
Throughout the years, plasma tvs have really come a long way, however, just like other tv types, they can lose brightness. Today's models of plasma tvs are considered to actually last the longest clocking in at around 100,000 hours. This equates to around an astounding 10 years! This makes the plasma television the longest-lasting tv tech in terms of brightness.
Plasma tvs used to have a negative outlook as being bulky and heavy considering how they operated. While this isn't untrue, it doesn't make their technology any less impressive.
Plasma tvs operate by a number of cells that have glass panels. These panels have a gap that allows neon-xenon gas to be injected. This process creates a sealed plasma form in the end. These types of tvs do not require a backlight usually as the phosphors that create the images along with the plasma cells generate light with the color pixels.
How Long Do LED Monitors Last?
Monitors for computers are also known for losing brightness and LED monitors tend to last about the same as the LED tv screens somewhere between 60,000 to 80,000 hours. It can be argued that monitors get more use than tv screens, but let's be honest, in today's society any screen is known to be in someone's face!
Once again when assessing how long a screen is going to last, it is necessary to know that they will all lose their brightness over time. This includes monitors as well. They generally operate the same way as tv screens. The cold fact still remains that LED lighting typically doesn't last quite as long as others.
Why is Does a Television Set Get Dark?
It can be misleading to say that dark tv sets are caused by a loss of brightness and this is because modern tvs come with power-saving modes. Power-saving modes often darken newer tv sets in an effort to be more energy-efficient.
In a world where tech is usually king, it is important to be as energy-efficient as possible. As is the case with the LED devices, this doesn't mean the product will last for nearly as long as we like, but we will know we've done our part in using energy responsibly.
What is the Best Brightness Setting for a Tv?
The preference for brightness is totally up to the user, but the best setting has been said to be a 50% brightness level, a 100% backlight level, and a contrast level of 100%. These three things combined will provide visuals that are acceptable to the eyes.
In making these adjustments, it is crucial to remember that the backlight setting will aid in any attempt to extend a lifespan of a brightness display. The setting of the brightness will only be a preference for the user and this is largely based on how it feels when looking at the screen. Obviously higher brightness levels may not be appropriate for all eyes, as some are sensitive.
The world of television tech has come a long way over the decades, but understanding the importance of the lifespan associated with the loss of brightness helps everyone appreciate their devices even more!
