The blue core is the road to the evolution of laser projection from BenQ
Laser light sources have become the main direction of projector upgrades in recent years. The problem of lamp life and thermal attenuation of traditional light source projectors has always been the focus of users' concerns. Obviously upgrading the laser source is the best way to solve this problem. In recent years, laser projectors have been used in various market segments, from education to engineering, from home to projectors. So how is the laser source developed? We take BenQ as an example to give you a look at the history of laser source projectors.
BenQ released blue nuclear laser projector in 2012
The technical principle of the blue nuclear laser projector
On March 28, 2012, BenQ BenQ officially released a new light source technology in Beijing - BenQ Blue Light Engine. Since 1996, Texas Instruments has authorized the development of DLP projectors. Since the first development of the first optomechanical engine in 1997, BenQ has become the industry's first projector manufacturer of laser light source technology in 2012. The BenQ Blue Light Engine uses the industry's latest high-brightness blue laser diode module to replace the traditional heat bulb source. From the actual projection effect, the blue nuclear light engine casts a colorful picture and sharp handwriting, combining the advantages of DLP detail and the colorful features of LCD. The new LX60ST/LW61ST's blue-core light engine will provide a lifetime of 10,000/20000 hours (standard/energy saving). In 2014, BenQ also introduced the upgraded LX20ST, which further expanded the BenQ laser projector product lineup.
BenQ laser projection has always been based on blue laser
In 2015, BenQ launched its role in the education market, launching direct-projection and a variety of reflective ultra-short-focus educational laser projectors. BenQ LW22STD uses a new generation of blue nuclear laser light source, which can bring users 3000 lumens high brightness, 20000:1 high contrast and WXGA high definition image quality. In addition, LW22STD has a projection ratio of 0.52, and 1 meter can cast a large screen of 90 inches or more. Coupled with the 130% wide range of lens vertical displacement function, it can be easily hoisted in the classroom, avoiding direct light and protecting the eyes of both teachers and students. Different from the direct injection LW22STD, BenQ LX80CUST/LW81CUST is the flagship product of ultra-short-focus laser education projection equipped with internal reflection technology. The projection ratio is 0.29/0.23, which is the best in the industry. The projection distance is unprecedentedly shortened, completely solving the problem of light irradiation; The 455nm pure blue laser source provides greater illumination for high brightness, while the professional education projector is the first to achieve full coverage of the Rec.709 gamut space.

In other respects, the LX80CUST/LW81CUST is equipped with high-precision industrial optical lenses to provide high-definition and distortion-free image quality; the industry-leading SmartEco smart energy-saving technology further helps users to extend their service life and reduce costs; and IP5X protection level A comprehensive multi-level professional dustproof system for super high stability and durability.
Since then, BenQ has continued to expand the laser projector market, and the engineering market has become a new direction for BenQ. In 2016, BenQ released products such as LU9715 and LU9235. These new products are professional engineering projectors that are targeted at large venue applications. The LU9715 uses a 0.67-inch WUXGADLP chip with a resolution of 1920×1200, a brightness of 8000 lumens, a contrast ratio of 100,000:1, and a lamp life of 20,000 hours. It has 8 optional lenses and supports HDBaseT for easy engineering installation.

To take advantage of the high output of the BlueCore laser, BenQ Laser Engineering projectors use a two-color wheel system that produces RGBY colors for enhanced color brightness, accuracy and color gamut space. BenQ achieves a vivid picture by converting only the color wheel of red, green, blue and yellow. With this optimized RGBY color, BenQ laser projectors produce superior color and a wider color gamut. In addition, the LU9715 features power zoom, lens shift, geometric correction and compatibility with 8 sets of projections covering TR0.38 to TR8.19. The lenses are all made of glass lenses and a large aperture structure, ensuring ultra-clear focus and brighter images at different projection sizes.
2017 BenQ released home laser TV
Now that time has come to 2017, BenQ has released a new laser TV product I955L, etc. It is obvious that BenQ has made a new layout in the home market. Recently, there is news that BenQ will hold a new conference in August. Is there any BenQ's new laser projection at this conference? Let us wait and see. In fact, the development of BenQ laser projection is basically consistent with the development of laser projectors in the projector industry. The future of lasers is becoming more and more important in the projector industry.
