In recent years, Sony has been promoting the projection in the camera, that is, adding a projection light bulb in front of the screen. The latest PJ820 has achieved 50 lumens and automatic calibration technology. Not bad, but not in line with black technology, because it is getting thicker and thicker. No matter how much money Sony TV lost, in my opinion, this is a very respectable department. He once contributed to the brilliant television career. In today's impetuous TV industry, only he has been working hard for the most basic and important display quality. Sony has been unmoved when other TV stations are producing Android TV. KDX-46Q005 is Sony's first RGB three-color backlit TV set, followed by X300a x4500 and other models for the civilian population. At present, our LED backlights all use blue light as the backlight. This is not a pure white lamp. Why, I don't know ... Many people know that the mixed color of RGB is white. This white is the purest. Then why not use RGB three-color lights as backlight? The reasons are high cost, high process requirements and high power consumption. This thankless thing is purely done by Sony, a black technology. But the picture quality he came out is really great! Color reproduction will be very accurate.
