Haier 3d TV What is the difference between Haier LED TV

3D TV is used for**3D film source Ordinary 2D film source can also be** LED mainly refers to the screen is more energy-saving and power-saving Glasses are also better for ** It is recommended that if it is not long**3D film source, it is better to choose a better LED on the line.

3D is an abbreviation for three-dimensional, which means three-dimensional three-dimensional graphics. 3D TV, 3D LCD TV is by adding a special precision cylindrical lens screen to the LCD panel, and the encoded 3D** image is independently sent into the left and right eyes of the person to produce a three-dimensional effect, which allows users to experience the three-dimensional feeling without the help of stereoscopic glasses, and can be compatible with 2D pictures.

In order to improve the picture quality of LCD TVs, TV manufacturers began to use LEDs as the backlight of LCD TVs. Compared to traditional LCD TVs that use fluorescent tubes as backlights, LED LCD TVs can display more realistic colors. In addition to the color saturation increase, the dynamic adjustment of the picture can make the brightness and contrast can be dynamically corrected when displaying different images to achieve better image quality.

In the strict sense, LED TV refers to a TV that completely uses LED (light-emitting diode) as a display device, which is generally used for low-precision display or outdoor large screen. At present, the strict name of LED TV usually referred to in the home appliance industry in Chinese mainland is "LED backlight LCD TV", which refers to LCD TV with LED as the backlight, which is still a kind of LCD. It replaces the traditional fluorescent tube with LED light source, which has a better picture, longer theoretical life, more environmentally friendly manufacturing process, and can make the LCD panel thinner.
