No need to replace the light source or air filter, providing a dramatic reduction in TCO.
Excellent picture quality and brightness are maintained for a long time.
Beautiful, vivid colors exceeding the levels of conventional projectors.
The image appears almost instantly upon powering up, and there is no need for cooling after turning the power off.
The power can be turned on immediately after being turned off, and it can be turned on/off as many times as you want.
This new light source requires no maintenance for approximately 20,000 hours.* In many cases, this means no maintenance until your next refresh cycle. Naturally, there are no lamp burnout problems during use, so reliability is further increased. There is also no filter to clean due to carefully engineered sealed optics.
As a consequence, running cost is dramatically lowered because of the savings on lamp costs, maintenance labor and hassle of stocking lamps.
* A guideline for light source replacement. The maintenance-free period may be shortened due to environmental conditions.
The PT-RZ470/RW430 features 3,500 lumens of brightness.
Rate of brightness deterioration in the LED/Laser-combined light source is extremely slow compared to lamp-based projectors.
The SOLID SHINE drive uses a built-in sensor to constantly detect the light intensity of the light source and correct corresponding changes in white balance. This all helps to maintain excellent picture quality for a long period of time.
Contrast is outstanding too, at 20,000:1, and images are reproduced with a wide dynamic range. The PT-RZ470 also features a Full-HD (1,920 x 1,080) DLP™ chip, allowing highly detailed Full-HD images without resizing.
The LED/Laser-combined light source has a higher level of color purity than an ordinary lamp, allowing it to achieve color reproduction with wider color space. Colors are more vibrant than those of conventional projectors.
In 1-chip DLP™ system projectors with conventional lamp, a color wheel is used for time-division multiplexing in a method
where the human eye combines the result to achieve a full-color palette. In the PT-RZ470/RW430, this is done by on/off
switching of the LED/Laser-combined light source. A unique Panasonic power supply circuit provides time-division
multiplexing with ultrafast 30x drive.* The resulting, high-definition images exhibit virtually no color breaking.**
* Picture mode: Dynamic. 10x drive in other picture modes.
The rate for each vertical sync/blanking interval, with R/G/B light source switching set to 1x.
** A condition in which incorrect color expression causes color flickering.
Laser cooling is performed by releasing the heat to cooling fins, then cooling with a heat pipe cooling system. This suppresses temperature rises inside the projector and allows stable operation up to an ambient temperature of 45 °C (113 °F).*
The use of this heat-pipe cooling system also achieves quiet operation of 29 dB,** enabling viewers to concentrate on the presentation or on quiet movie scenes.
* The operating temperature range is 0 ºC to 40 ºC (32 ºF to 104 ºF) when used in locations from 1,400 m to 2,700 m (4,593 ft to 8,858 ft) above sea level. If the ambient temperature exceeds 35 °C (95 °F), the light output may be reduced to protect the projector.
** LIGHT POWER mode: ECO. 35 dB with LIGHT POWER mode set to NORMAL.
The area between the LED/Laser to the DLP™ chip and prism is hermetically 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.
Panasonic’s Daylight View Basic technology achieves sharp, easy-to-see images by clearly reproducing the details in dark image areas, which were previously difficult to see in brightly lit rooms. A built-in sensor measures the ambient light, and the Daylight View Basic function adjusts the halftone color and brightness level according to the surrounding illumination.
This imaging mode is similar to DICOM part 14, which is a medical imaging standard. It reproduces X-ray images with remarkable clarity.
* This product is not a medical instrument. Do not use it for actual medical diagnosis.
Optimal color reproduction can be achieved by selecting this mode, compliant with ITU-R Recommendation BT.709,
when images from an HDTV source are projected.
