3D TV is the "energy" runs counter?

3D TV is that one of the main image darkened by the influence of the shutter glasses. Shutter glasses will be used the light transmittance of the polarizing plate down. Different types of 3D TV, then the shutter glasses required number is not the same as the polarizer, some one, and some are two. Of course, using a decrease in the transmittance will be smaller, but this time the visual environment and there is a considerable restriction. This will make an analysis of the relevant circumstances, energy saving and television and 3D TV to start on.

    PDP need cars polarizing plates, while the LCD, although only a limited but audiovisual posture

    If it is, then the PDP panel light emitted essentially belongs to natural light, not polarized. Therefore, in order to make glasses with shutter function, you must use two polarizers. The side of the glasses is not natural light into polarized light, then the liquid crystal shutter will not function. And this transformation will reduce the incident light to the liquid crystal glasses half or less. But also  SUNGOLDPOWER produces two polarizers considerable transmittance loss (approximately 90% each). Therefore, the article described the Toshiba Mobile Display (TMD) 3D glasses with OCB LCD panel transmittance of 33%, is consistent with the facts. However, the transmittance of the shutter glasses low but also to have a beneficial aspect. That is, slightly tilted head, still can see some 3D images.

    The LCD is different, the light emitted by the panel is polarized. Therefore, as long as the polarization axis of the polarizer glasses and overlap the side of the panel without the use of optical polarizers. Because only one polarizing plate can, therefore basic optical transmittance is substantially the transmittance by the polarizing plates (about 90%) is determined. However, this structure of the optical transmittance is advantageous although some, but there are also weaknesses. This is to make the polarization axis of the liquid crystal panel polarization axis coincides with glasses up, in other words must not have head tilt. With the head tilted, crosstalk phenomenon will increase. Sharp 3D LCD TV LC-LV3 series of operating instructions to indicate the note: "the need to wear 3D glasses, close to the level two state watch."

    In addition, PDP TV viewing 3D images, lighting "fluorescent" will form a flashing light, the eye. This flashing is sometimes less obvious, sometimes it will feel. This is caused by the shutter glasses. Shutter Although the light emitted by the PDP screen synchronous switching, but to 50Hz or 60Hz repeated natural light fluorescent light and shade, will also play functionality. Close the shutter opening and closing cycle fluorescent light-dark cycle of two or four times, so will lead flashing. Figuratively, it feels like this is to make 60Hz driven liquid crystal panel backlight to 61Hz light off the same. The use of a polarizing glasses are different, the shutter on the role of natural light is small, easy to feel flashes.

    In order to avoid television viewing 3DPDP felt when flashing, lighting only in audio-visual environment to take countermeasures, or replaced using an dc ac inverter fluorescent lighting and popular LED lighting, or re-use the original incandescent lights and even watch .

    Use LCD shutter glasses to watch 3D images darken

    As mentioned above, 3D TV somatosensory brightness due to the shutter glasses are one or two polarizers varies. But either way, should on this basis, coupled with the resulting monocular viewing "somatosensory half brightness." Thus, the two-dimensional (2D) image compared TV, 3D TV brightness will be reduced to less than half.
