Welche Bildschirmtechnik ist am besten für eine gute Grafik und Farben?
Hallo, ich will mir eventuell ein Tablet zulegen um auf Reisen entspannt Serien und Filme gucken kann. Ob es FullHD oder etwas besser werden soll weiß ich noch nicht, aber die Farben sollen natürlich passen, vorallem soll der Bildschirm einen guten Schwarzwert haben.
Deswegen möchte ich fragen was dazu am besten geeignet ist. LED, OLED, LCD, oder welche es noch alle gibt.
Of course, this is also very important to your personal taste. Various display techniques have different “characteristic” properties, which please the one more than the other. Here is a list of the most important species
LCD screens
This describes a technique in which different color values are generated with the aid of crystals, and by means of a backlight they then “glow” them.
The advantages are primarily the low price, but the drawbacks above all that you can create with a continuous backlight, no really “depth black” – black surfaces will always glow gray.
In the LCD range, there are various specific pannel types, each of which has & disadvantages. The 3 most known are TN panels, VA panels & IPS panels.
Of these, TN is the “badest”, VA is the “medium” and IPS is the “best”, with this mainly referring to color reproduction. TN & VA Pannel have the reputation of being rather “grey” and bringing washed-out colors, but also have lower reaction times, which can be advantageous for gaming.
IPS panels are still very often used today, and mainly offer very strong colors, but a lower reaction time. The “retina displays” installed in many Macbooks are, by the way, IPS panel and up to Iphone 12 the “not Pro” models also had IPS panel.
LED screens
Instead of installing a “outgoing backlight” in a panel, there are many small LEDs which can be controlled independently of one another. In principle, there are still many larger pixels behind the pixels of the screen, and depending on which color is to be displayed in which screen area, certain LEDs are switched on/off or dimmed.
This makes it possible to realize very high contrasts & black values with a backlight. For this, one has the disadvantage that at sharp edges, i.e. at places where bright image areas coincide with black, the bright areas begin to “glow” because the background lighting is not exactly enough.
This technique is currently used in Ipad Pro, Prodisplay XDR and Pro-Macbook.
OLED screens
Here the backlight is completely omitted, and instead each individual pixel is made “lightable”. As a result, unnecessary image areas are completely switched off, and are therefore also completely black – this allows almost unlimited high contrasts and extremely bright colors.
OLEDs used to have many children’s diseases, including “burning” content, problems with certain angles of view, as well as strange white values, etc., which have meanwhile almost all been fixed.
OLEDS can be found virtually in any semi-distant modern phone, and in many places are considered the best one can get.
In itself, however, it is also a large part of a matter of taste. I myself find OLEDS super, but I also know many of whom the colors are much too overturned, and therefore IPS panels or IPS panels. Mini LEDs prefer.
If you buy a tablet to watch movies, you only have the choice between IPS panel and OLED panel, with the “more expensive” devices actually only installed OLEDs.
On the other hand, you only get a mini LED display with the IPAD Pro, for an IPS panel you need to look in the entry field.
For videos I would take an OLED panel, but it can also be that you don’t like it.
I therefore advise you to look around in Saturn or Media Market and check what your eyes like best.
“LED” is LCD. This means that white LEDs are used as backlights instead of fluorescent tubes.
LCD is available in various designs. TFT is the first variant where the pixels are actively controlled by transistors and thus the signals of the pixels are not in adjacent pixels or Columns and rows “bleed”.
The current LCD version is IPS. Here, a special arrangement of the liquid crystals ensures better colors and a large viewing angle.
So LCD, LED and TFT are terms that mean the same thing today, that’s just marketing.
LCD/TFT/IPS have the disadvantage that the backlight is always “full” and the panel swallows between 50% and 99% of the light, depending on how bright the pixel should be. This naturally takes a lot of electricity, even if you look at a black screen.
At oLED, the pixels consist of individual LEDs that can be locked in and out. The pixels thus light themselves and the whole only needs as much power as bright pixels to be displayed. Also, the half of the light is not lost so that the oLED panel saves half the current or can represent much higher brightnesses. This is interesting at HDR. You can really be blinded by the panel when the director wants it, for example when the actor escapes from the darkness after a long time and goes into the sun. Then the viewer (something) is also blinded. Video games also use this more often.
The disadvantage is that oLED is much more expensive! But even with mobile, this increases the battery life enormously.
I’ve been looking for a Linux tablet for a long time. But all were either very expensive or even “Early Access” or failed. Now I bought a steam deck last year.
With this you can not only play games from Steam but also select “Exit to Desktop”, then you come to a Linux interface. And in there you can use any Linux program that also runs on a PC and also via “Wine” Windows software. Here you can also conveniently watch videos via VLC or via website (Netflix, Amazon Prime, etc). Of course, you can save and play the movies on offline on an SD card.
The touch screen is incredibly good, much better than on low-priced trays and the battery keeps “full performance” up to 3 hours. If you look at movies, it’s 8 to 9 hours, maybe more. You can also extend the load or runtime by phone Powerbank. This should then be 40W if you want to charge the internal battery with zocken, up to approx. 24W needs the steam deck for itself while shocking. Watching video runs from 6 to 8W. I have the 512GB oLED version. The currently cheap sold TFT naturally needs more electricity or the battery is empty faster.
On the way, I would recommend the 1TB version. This is significantly more expensive and 512GB is more than enough (especially since you can use SD cards, even for games), but the 1TB version has a mirrored screen that does not have 512GB and small versions!
The only drawback on the Steam deck is that, unlike the switch, you cannot lose the controllers. So you always have a large device with a relatively small screen for its size. However, this is technically conditioned, the batteries are seated under the controllers. So unfortunately not as handy as the switch, but much more powerful and can do much more.
By the way, the VLC and Firefox can be registered in the Steam so that you can start it immediately like a game.
Force Feedback or “Rumble” doesn’t have that thing. But it tries to simulate this about the feedback of the touchpads, so unfortunately very weak.
With a stand, Bluetooth mouse and keyboard you can then use it as a full PC. The stand can also be connected to a TV. It does not have to be the expensive €300 stand of Steam, I am satisfied with the €30 things here:
