Hisense's Leading Laser Television Technology Reduces Construction Costs of Private Theater Systems
Hisense's 120-inch laser TV product is specially designed for large-scale private theaters. It uses laser fluorescent light source and ultra-short focus projection technology. It uses monolithic DLP imaging technology and has excellent screen contrast. It is particularly prominent in high-light levels. . Hisense's 120-inch laser TV also incorporates a signal source function and a surround sound system, and the price of only 6-7 million yuan allows users to leave a budget for more functional expansion of the entire system. In addition, Hisense laser TV's performance in terms of color and brightness has been very mature and stable, integrating the core optical components of global suppliers to ensure the quality of the whole machine. The internal use of a variety of cooling methods combined to ensure efficient heat dissipation and dust, greatly extending the life of the machine.
Has a higher screen brightness, more depth of the large screen light and shadow characterization
Larger use of space requires larger screens, while larger screens require the display system to provide higher brightness support. Hisense's 120-inch laser TV exceeds the output brightness of 2000 lumens in mid- to high-end home theaters, reaching a level of about 3,000 lumens, allowing the details of the high-light levels to be characterized more deeply, and the transition between light and shadow is more uniform and does not appear stiff.
The wireless surround sound system and immersive three-dimensional sound system matched by itself
Hisense's 120-inch laser TV already has a 5.1 surround sound wireless audio system. Because it uses wireless transmission, it can be used as one of the main surround sound systems in the entire private theater program. For this solution's extended surround sound system, we recommend that you choose an immersive system that supports Dolby Atmos and DTS:X two-dimensional surround sound effects. In addition, in the choice of surround sound box system, the way of concealed sound box placement is the main choice. In-wall or embedded sound box system is the preferred choice. In terms of overall system configuration, it is recommended to choose sound box configuration of 7.1.4 or above. Ways to better present the advantages of three-dimensional sound effects in terms of spatial and detail.
In terms of signal source, UHD and cinema synchronization systems are at the core
Although the Hisense laser TV system itself has a very rich source of audio and video programs, such as 15,000+ movies, 150,000+ episodes, 73000+ episodes, and variety shows, anime, documentaries, etc., this does not fully satisfy the discerning high-end. The player's fever requirements, we recommend this program can be used with the Blu-ray player system and the top of the theater synchronized playback system, to meet the players in the first time exclusive to the cinema showing movies, without having to compete with others for the best viewing in the cinema position.

Brushless Permanent Magnet Motor
Brushless permanent magnet motors with low inertia rotors are used in high-performance servo applications such as machine tools or pick and place applications where fast, precise movements are required, and motors with high inertia rotors (and high pole-numbers) suit low-speed applications such as gearless lift systems.
The performance characteristics of these drives are summarized below:
They have excellent dynamic performance at speeds down to standstill when position feedback is used.
For precision positioning the position feedback must define the absolute position uniquely within an electrical revolution of the motor. This can be provided with a position sensor or alternatively a sensorless scheme can be used. The performance of a sensorless scheme will be lower than when a position sensor is used.
Field weakening of permanent magnet motors is possible to extend their speed range, but this requires additional motor current, and so the motor becomes less efficient in the field weakening range. This form of control also increases the rotor losses and raises the temperature of the magnet material, thereby increasing the risk of demagnetization. Care is also needed in such applications to avoid overvoltage at the motor and drive terminals in the event of a loss of control: at high speeds, the open-circuit voltage will exceed the rated value.
Brushless permanent magnet motors exhibit an effect called cogging that results in torque ripple. It is caused by magnetic reluctance forces acting mainly in the teeth of the stator, and can be minimized by good motor design, but can still be a problem in sensitive applications.
Brushless permanent magnet motors can be very efficient as the rotor losses are very small.
