Introduction

Laser TV is a modern technology that is gaining increasing popularity in the global consumer electronics market. One of the leaders in this field is Hisense, a Chinese technology giant that has been developing its expertise in electronics since the 1960s. In this document, we will examine the history of Laser TV technology, Hisense's particular contribution to its development, and the future of this innovative technology.

Part I: The History of Laser TV Technology

The Beginnings of Laser Technology in Image Projection

Laser projection technology began to gain attention in the second half of the 20th century, although it was initially developed mainly in the context of industrial and scientific applications. The first studies on the use of lasers in display devices date back to the 1960s and 1970s, when the technological foundations for generating images using light beams were being developed.

Laser technology had several unique advantages:

  1. Unmatched color precision: Lasers generate light in a very narrow wavelength range, allowing for the creation of more vivid and true-to-life colors.
  2. High brightness: Thanks to the high power of lasers, images were visible even in well-lit rooms.
  3. Energy efficiency: Compared to traditional projector lamps, lasers were more efficient.

Despite these advantages, early applications of laser technology were limited due to high costs and a lack of suitable components that could make it accessible to the mass market.

Laser TV Enters the Consumer Market

The first attempts to introduce laser technology into televisions and projectors occurred in the 1990s and early 21st century. The development of LED and OLED technology at that time diverted consumer attention, slowing the adoption of lasers in television. However, as production costs for lasers began to decrease and their efficiency and durability increased, the first products dedicated to a wide audience emerged.

Hisense, known for its innovative approach to technology, was one of the pioneers in bringing Laser TV to the mass market. In 2014, the first Laser TV device was presented, quickly gaining recognition for its image quality and affordability compared to large LED and OLED screens.

Part II: The Development of Hisense Laser TV Technology

Hisense as a Leader in Laser TV Technology

Since its inception, Hisense has placed a strong emphasis on research and development (R&D). The company has invested billions of dollars in the development of display technologies, including Laser TV. Key steps in the development of Hisense Laser TV include:

  1. Introduction of the first Laser TV model: In 2014, Hisense launched its first Laser TV, which combined the functionality of a projector and a television in one device. It was a device equipped with a laser projector that displayed images on a special screen.
  2. Improvement of image quality: Hisense invested in the development of 3-color laser systems, allowing for a wider color spectrum compared to traditional projectors and televisions. Models such as Hisense 100L7T offered 95% coverage of the DCI-P3 color space.
  3. Integration of smart features: Hisense Laser TV is not limited to displaying images. With operating systems like VIDAA, the devices offer access to applications such as Netflix, YouTube, and Amazon Prime, as well as advanced voice control features.
  4. Cost optimization: Compared to large OLED screens, Laser TV offers a more economical solution that does not compromise on image quality.

Key Hisense Laser TV Models

Hisense has launched many Laser TV models that have gained recognition among consumers and experts alike. The most important include:

  • Hisense 100L8D: One of the first models available globally, offering a 100-inch diagonal screen.
  • Hisense 75L9G: A model with a 3-color laser system that has won awards for image quality.
  • Hisense PX1-Pro: A device with ultra-short throw that has become popular due to its compact dimensions.

Part III: Laser TV Technology - How It Works?

Hisense Laser TV utilizes advanced technologies that distinguish it from traditional LED, OLED televisions, or projectors. Here are the key elements:

1. Laser Projector

The key component of Laser TV is the laser projector. It uses laser light sources to generate images, allowing for:

  • Higher brightness,
  • Greater color precision,
  • Durability (up to 25,000 hours of use).

2. Special Light-Reflecting Screen

Laser TV uses a dedicated screen with light-reflecting properties. This makes the image more visible even in well-lit rooms, solving the problem of projectors requiring dark conditions.

3. Smart Features

Hisense Laser TV is equipped with operating systems with smart features, making it not just a screen but a full-fledged multimedia center.

Part IV: The Future of Laser TV

1. Development of 3-Color Laser Technology

Hisense and other manufacturers are actively working on improving 3-color laser systems, which can provide an even wider color spectrum and greater brightness.

2. Cost Reduction

The costs of Laser TV technology are steadily decreasing, which may make it more accessible to the mass market. In the coming years, Hisense plans to introduce models in lower price ranges.

3. Increasing Resolution

8K resolution is becoming the standard in modern televisions, and Laser TV is no exception. Hisense is already testing Laser TV models with native 8K resolution.

4. Expansion of Applications

Laser TV technology can find applications not only in homes but also in offices, schools, or home theaters. With the compact size of projectors and easy installation, their versatility is increasing.

Summary

The Laser TV technology developed by Hisense is one of the most interesting achievements in the field of image display in recent years. With its advantages, such as a wide color palette, high brightness, and energy efficiency, Laser TV has the potential to revolutionize the consumer electronics market. The future of this technology looks promising, and Hisense, as one of the leaders, is on the right track to further improve and popularize Laser TV worldwide.

As production costs decrease and technological capabilities grow, it can be expected that Laser TV will become a common choice for those seeking large screens with high image quality.
