Definition of Roll up LED? How Does Roll Up LED Work?

 

Also known by the name roll-up display, a flexible roll-up LED screen is one which is easy to bend, can be rolled-up, scrunched, and is typically manipulated in ways that are not possible through the conventional display. You can roll up the display such as newspaper, making flexible screens simple to move around, or it can be stored in little spaces when these don't get used.

 

Roll-up the Flexible Screens or Use the Oled Technology

 

Viewing on the flexible LED is possible because of the benefits in organic light-emitting diode(OLED) technology, which would be a step ahead of the light-emitting diode (LED)from where light occurs from the back panel. While removing the requirement for the back panel, it is possible to display can bend.

 

A rollable or a flexible display would mean an electronic type visual flexible display, rather than the conventional flat-screen displays nowadays seen in a lot of electronic devices. In the past years, there has been an uplifting interest from various consumer electronics manufacturers for applying display technology in mobile phones, e-readers, and other types of consumer electronics. These screens are possible to roll like scroll without image text getting distorted. The technologies can involve building rollable displays that include Gycricon, electronic ink, OLED, Organic LCD.

 

The Technology Behind a Roll-Up LED Screen

 

The thing that separates your conventional LCD televisions from video projector screens is that you can't roll up the TV when you won't view it. Until now, the roll-up TV, (also known as the rollable TV) arrived. Let's know what this would mean for the customers.

 

The underlying technology required for using a roll-up TV is the OLED (Organic Light Emitting Diode). The OLED TVs use an organic structure meant to form pixels to form images, without the requirement for additional backlighting. This also makes the OLED TVs different compared to the QLED TVs or the LCD/LED TVs. The OLED screens can be made so when they'll bend curve, fold, and also roll while depending on the application (like the displays of the in-car instrument and foldable smartphones).

 

How Roll-Up TVs would Work?

 

The thin OLED TV display panel would be combined in little interlocking segments with the folding brace on the screen back for securing it to the rolling motorized mechanisms. The screen panels would wrap around the cylinder within the storage housing. The total roll-down and roll-up time would be around 10 seconds (can be different from the screen sizes).

 

It is possible to activate the rolling process through onboard, remote, or manufacturer voice control.

 

What the Roll up LED Screen Can do?

 

The screen panels that you see in the roll-up TV were developed and made through the LG Company. (Not the LG Electronics). The LG electronics company is the first brand ideal for adopting the rollable LG OLED technology for consumer TV.

 

Features of rolling LCD

 

They're generally available in 65-inch size screens. The rolling screen is available for viewing in three positions: The Line View, Zero View, and Full View.

 

  1. * Line View: The screen gets retracted to a-quarter of the height. This also adds access to control and features like the Clock, Photos, Music, and special LG's Home Dashboard version when you're not watching the TV.
  2. Full View: The position can display a total 16x9 ratio aspect screen to watch movies and TV shows.
  3. * Zero View: The TV screen gets retracted into the base when it's not required.

 

The OLED technology also doesn't support any resolution like the 1080p (FHD), the 4K (UHD), and the 8K. However, the LG Display selected the 4K that can be implemented on the first generation rolling OLED TVs. Also, manufacturers add video processing features like HDR and upscaling.

 

With different manufacturers, you can include more base features for housing screens. The LG-R series base also contains a rollable sound system of the TV (you can think of this as a huge soundbar). The sound system also features a 5.1 channel speaker configuration backed through 100 watts amplification. No firing or height speakers are there but audio processing algorithms make a height effect for the source of Dolby Atmos. Additionally to the sound system, the base also provides many input connections (such as HDMI, etc...) with a tuner.

 

Considering Differences Between a Roll-up and a Lift-Up LED TV

 

It's best to know the difference between the rolling and the conventional lift-up LED televisions. If you've got a conventional LCD/LED, OLED, or QLED TV, it won't be possible to roll them up. However, these can be combined with a cabinet especially having a lifting mechanism for raising and lowering the TV to view and the storage which is required. Also, there are lift mechanisms possible to mount within a ceiling.

 

As the TV does not roll up, the ceiling or cabinet should have enough interior space meant for accommodating the weight and size of the TV when it wasn't in use. It meant that besides the cost, the ceiling lift mechanism or cabinet was compatible with a certain TV size that you wanted to use.

 

After comparing to the LED with other technologies, the OLED can provide users with the benefits such as:

 

  1. * Fast refresh rate since no pixel shutters are used
  2. * Energy-efficient as the backlight doesn't get powered. Also, when you use black, certain pixels don't require power at all, further saving more energy.
  3. * The refresh rate is quicker as no need for a pixel shutter is there.
  4. * With only fewer components the device along with the display would be lightweight and thin.
  5. * Supports a wide viewing angle without any sign of color on the LED.

 

Should you choose a roll up display screen?

 

When craving the best and latest and you've got spare cash, then it would be best to have it. However, it would be best to wait for some time to ensure the reliability of the concept. You can wait till the concept grasps some market demand (just like the Curved screens and 3D), prices can be down and there are many more available screen sizes as well.

 

Here are various other things to know as well: It's not best to wall mount roll-up TV because of the necessity of having a base for housing screen (unless the wall can handle the base weight - and it also sticks out).

 

Also, it won't be possible to mount up the TV base on the ceiling. Although it would be possible to roll the screen upside down, as there isn't any provision for inverting screen images as it is available with a lot of video projectors. It means that the images can also turn upside down.

 

Although many small prototypes of flexible OLED panels are demonstrated that can roll similar to a "yoga mat", we will have to wait for a while before the convenience would be available for the TV-sized screen. When this is done, you might be able to roll the screen up into a poster tube-like container while unrolling it, and also remove or attach it from an easel or wall-like stand easily.

 

Reasons to Get Roll-up LCD

 

The foldable display qualities provide adequate compactness when it is not being used. Rollable OLED screens also offer great performance features that are not possible with the current day LCDs. Also for their lighting use, the rolling OLED can provide various benefits over fluorescent and incandescent lighting. OLED benefits also include:

 

  1. * Light and Thin Weight - The rolling OLEDs are built on thin metal or plastic foil. The rolling OLEDs are thin and light compared to the backlit LCDs along with other displays nowadays available in the market. So the portable computers, cell phones, and other display products can also be small and light. Also, the FOLED technology facilitates easy] wall-mounted televisions along with the installation of the white OLED lighting tiles in settings, and make novel architecture uses not possible with the current day incandescent and fluorescent lights.
  2. * These are safer, more durable, and impact-resistant - Breaking glass is a major issue for display-containing products and is a safety concern in the lighting field. The metal and plastic-based OLEDs can essentially eliminate such issues while also making obvious benefits in both lighting and displays.
  3. * Cost-efficient - Nowadays, the OLEDs can typically make use of production techniques relying on sequential processing of the discrete glass panels. With flexible substrates that would originate typically in roll-stock format (such as paper rolls), it gets envisioned that the OLED production can evolve to high throughout the roll-to-roll processes, as it is used commonly in the printing industry. This can provide the basis for low-price mass production.

 

Nowadays flexible screens are total HD and provide resolution for more than 1,200 and 810 pixels. The current prototypes are around 18 inches, but the innovators also include the LG expect for pushing flexible screens to 55-inch size. The LG display provided a look at the 180inch prototype screen at Consumer Electronics Show in January 2016. It is possible to manually operate the TV lifts, but these are often motorized to make it convenient.
