 The Television technology has been evolving since the introduction of TVs. The need to provide a mesmerizing experience to the users is the driving force behind the innovations. Screenless TVs are the latest development in the era of modern television.

Screenless TVs are innovative devices that allow individuals to enjoy a captivating experience. They defy the conventional definition of TVs as they display video without the need for a glass panel. Modern flat panel TVs either use Liquid Crystal Displays (LCDs) or have Light Emitting Diodes (LEDs) for displaying the images. A Screenless TV, on the other hand, displays images directly on the wall or a reflective screen. Screenless TVs are a class of projectors with additional capabilities and features. Different types of projectors come under the definition of a screenless TV. These include

Laser TVs – A Laser TV, sometimes also referred to as a Laser Video Display or Laser Screenless TV, is a projecting device that makes use of multi-colored rays emitted by lasers to project images and videos. It uses three lasers with different wavelengths to emit red, green and blue lights. They support a wide color gamut as they can alter the wavelength of the laser to produce different colors. Color gamut represents the range of different colors recognizable by the human eye that a device can produce. The wider is the color gamut of a device, the more vibrant looking images it will produce. Device with narrower color gamut might output pale images with washed out colors. Laser TVs have a color gamut of up to 90% which is almost double the color gamut of conventional flat panel TVs.

Ultra/Short Throw Projectors – Ultra or Short Throw Projectors are models that have a short throw ratio. The throw ratio of a projector defines the distance at which the projector must be installed for producing an image of a specific width. A projector with a throw ratio of 1.5:1 will produce an image with a width of 1 foot when it is installed at a distance of 1.5 feet from the screen. The same projector will produce a 6 feet wide image when it is installed at a distance of 9 feet.

Short Throw projectors have a low throw ratio ranging from 1:1 to 0.4:1 while ultra-short throw projectors have a throw ratio of 0.4:1 or less. These projectors can produce a wider image at a small distance of a few inches from the screen. They have high-quality lenses made of superior quality glass as compared to the lenses of projectors with a normal or long throw. These lenses produce a large image at a short distance from the screen. They are available with resolutions of up to 4K making them ideal replacements for flat screen TVs.

Smart Projectors – A smart projector is like a regular projector but has additional features. It has an operating system with video processing capability and multiple I/O ports for plugging in devices like USB storage drives, memory cards and keyboards. It can even connect to wireless networks or smart devices. While regular projectors need an input signal from a source like a laptop, a smart projector can display images directly from an internal or external storage media. They can even connect to on-demand video services like Netflix and social media websites like YouTube. They have LED bulb for projecting the image and are small, lightweight and portable. JMGO P2(also called JMGO View) is such a portable smart projector and below is the introductory video:


Screenless TV vs Modern Flat Panel TVs

Screenless TVs are different from flat-panel TVs in many ways.

- A 100” screenless TV is much cheaper than a 100” flat panel TV. Homeowners can enjoy their favorite movies and sports in high resolution without having to spend a lot of money.

- As a screenless TV is a small and lightweight device, it is super-portable and can be moved from one room to another effortlessly. It makes them great for homes and establishments that might undergo remodeling or those that frequently change the position of their devices.

- The devices also reduce the amount of eye-strain compared to flat-panel TVs as the light is not reflected directly towards the eyes of the viewers.

- Screenless TVs are easy to install and free people from the hassles of mounting them to the walls. They also protect the walls from the unsightly mounting screws and drilling and ensure they look as glorious as ever.

- They are smart devices that can connect to the home network or other devices like smartphones and NAS storages wirelessly.

- Screenless TVs have a sleek, modern design that complements the décor of the home or offices while flat-panel TVs may or may not have a great design.

- The viewing angle of screenless TVs is much wider than flat panel TVs.

Screenless TV vs Projectors

Screenless TVs are a class of projectors, but they have a few notable differences in comparison to the regular projectors.

 - While projectors are installed away from the screen, screenless TVs are quite close to the wall or the screen. They have a short throw ratio which means that they can produce large images while being close to the screen. Projectors meanwhile have to be placed far from the screens to get an image of optimum size. 

- Screenless TVs mostly use lasers or LEDs that have a longer life as compared to lamps used in projectors. The picture quality of screenless TVs with LEDs or lasers will not degrade as much with time as seen in projectors with lamps.

-They are easy to install and do not require mounting hardware like projectors and can be simply placed on a table. They also don’t create a tangle of wires and are compact and portable home theater systems.

- Another advantage of screenless TVs is that there is no chance of a person coming between the projector and the screen and spoiling the viewing experience. People no longer have to worry about missing an iconic moment of the movie or the sports game they are watching.

- Screenless TV models may have features like hand gesture control, inbuilt speakers, quad-core processors, Wi-Fi connectivity, Solid State Drives (SSDs) and multiple I/O interfaces which are not common in projectors.- Screenless TVs are more expensive than regular projectors, but they are a great option for homes with limited or narrow space.
