Long Life
A new heat-resistant material is used in the phosphor wheel to withstand the high output of the laser light source. Combined with a drive system that is also optimized for the light source, this made it possible to achieve the world’s first 6,500 lm of brightness in a 1-chip DLP™ projector. Actually, the result of Panasonic efforts to optimize color reproduction enabled a perceived brightness that even exceeds the specification values, thus opening the door to a wide range of applications for the PT-RZ670 and PT-RW630.
A material with excellent heat resistance is used in the phosphor wheel. This achieves both high brightness and long-lasting reliability.
High Contrast
The PT-RZ670 projectors directly control the output of the laser light source itself, enabling faster response than lamp-based projectors. Frame-by-frame scene-linking modulation with complete digital control makes it possible to adjust the light output with higher precision. This gives the PTRZ670 its remarkable 10,000:1 contrast without lowering brightness.
This enables highly precise contrast control even when bright and dark scenes suddenly or frequently interchange. There is also almost no reduction in contrast when the projector is used for extended periods of time.
It is almost impossible to imagine that a laser light source would suddenly go blank.
The PT RZ670 projector uses two sets of light sources that group laser diodes into a number of modules. Based on redundant design, the laser diodes are put to considerable use, so over the long term, if a laser diode were to stop functioning, a protective circuit would activate to keep the brightness drop extremely small. Even if this were to happen during 24/7 operation, it would not result in downtime. The dual drive structure also keeps the optical engine output uniformly bright and colorful even if the light source's original brightness is different due to aging degradation.
Normal Mode Enables Approx. 20,000 Hours of Continuous Operation
In NORMAL mode with brightness of 6,500 lm, the pt-rz670 Series projector requires no maintenance for approximately 20,000 hours. in ECO mode with brightness of 5,400 lm, the length would be approximately 24,000 hours. These modes are suitable for frequent but not continuous usage, such as education or signage applications.
Constant Brightness Modes for Long-Term Applications for up to 10 Years
Installation conditions for surveillance applications such as control rooms and simulations do not require the high brightness of 6,500 lm. Lowering the output of the laser light source extends its life span.
With this feature in mind, the PT-RZ670 has been equipped with operating modes that lengthen the usage time and maintain a constant brightness. For instance, in LONG LIFE 3 mode, it boasts up to 87,600 hours of continuous operation, i.e., about 10 years of 24/7 projection, while maintaining fixed brightness and picture quality.
User Operating Mode
In addition to the preset operating modes, the Panasonic PTRZ670 can be customized to match your application—with greater brightness or a longer life. You can set the brightness to range from 650 to 6,500 lm, or set the lifetime for a maximum of
10 years, whichever you choose.
Powerful Liquid Cooling
The PT RZ670 employs newly developed cooling systems for the laser light source and DLP™ chip to suppress temperature rises inside the projector, allowing stable operation up to an ambient temperature of 45°C (113°F).* The use of these cooling systems also achieves quiet operation of 35 dB, enabling viewers to concentrate on the projected content.
The liquid cooling system directly cools the laser light source modules. It also enables the high brightness of 6,500 lm even in an ambient temperature of up to 45°C (113°F).* The system is hermetically sealed, so you don't need to replenish the liquid.
Dust Resistant
The area between the laser light source to the DLP™ chip and prism is sealed to form an airtight structure for the optical block, the heart of the projector. This resists the effects of dust and other particles in the air, and enables use of the projector in a wide range of environments. This dust-resistant structure also maintains excellent picture quality and brightness for a long time and enables filter-free operation, all of which contribute to a lower TCO.
