False brightness standards have been widely used in the projector market,There has been no unified brightness identification rules in the domestic market,It gives some businesses an opportunity。 The default brightness standard in the projector industry is the American ANSI lumens,2005In 2005, Japanese manufacturers formulated another brightness standard - ISO lumens,Panasonic is one of the initiators of this standard。
 
There is a saying in the market that the ISO lumens of the same value are several times lower than the ANSI lumens, which is a miscommunication. In fact, the ANSI and ISO lumen measurement methods are similar, and the two standards only have different requirements for the projection size and projector specifications, and the difference in test results should not be large. The best proof of this is Panasonic, which is not difficult to find through its official information that Panasonic uses the ISO 21118 international standard to mark brightness, and the value is not significantly different from other brands. Therefore, the difference between the actual brightness of the projector and the nominal brightness is too large, the reason will not be that the identification standards are different, and the possibility of the merchant exaggerating or misleading consumers is higher.
 
As a traditional powerhouse in the field of white goods, Panasonic is very outstanding in terms of exterior design. Its products are mainly in white tones, the projector is angular and clear.
 
Among the basic products, Panasonic's representative product is the PT-WX3400. Unlike other manufacturers, PT-WX3400 has a resolution of XGA (1024x768), which is not the lowest SVGA (800x600), but the price has also increased to about 3000 yuan. In addition, the widescreen PT-WW3600, PT-UW313C and other basic models also have a brightness of more than 3000 lumens. The high-brightness PT-W4200 achieves 4100 lumens of brightness, which is more suitable for slightly larger conference rooms. Several projectors support USB direct reading, and can be equipped with an optional wireless module, which is easy to use.
 
In terms of lightweight models, Panasonic PT-SX1100, PT-SX2000, PT-SX3700 and other products are of good quality, and the overall shape is similar to ordinary business models, but the color is no longer pure white, and the top surface has been changed to champagne gold, which is more recognizable. Several projectors weigh just over 2kg, which is much lighter than the previously mentioned PT-WX3400 and other models. Several portable business projectors have a brightness of 2800~3700 lumens and a resolution of 1024x768, which is suitable for small conference rooms. According to the different brightness, the price ranges from 2000 to 4000 yuan, and the cost performance is still good.
 
Although home appliances have always been Panasonic's strongest field, Panasonic is more concerned about business education and engineering in projectors. As a symbol of strength, Panasonic engineering projectors have had successful cases at the Shanghai World Expo, Milan World Expo, and the London Olympic Games. In addition to the aforementioned basic business model, Panasonic's flagship business model is just as good. The PT-BW550C and PT-BX665NC projectors with 1.6x zoom and lens shift support are both 5500 lumens of brightness. This kind of projector is more suitable for some "big scenes", and can realize the seamless splicing of multiple projection units through color correction technology, which is not so much a business model, but an entry-level engineering machine. The PT-BX440C of the same series has a brightness of 4500 lumens, and the shape and weight are lighter, which is also a good high-end business machine.
