4TCL L43V7300A 3D principle to resolve to the top

Five, TCL L43V7300A-3D 3D principle analysis:

Because people's two eyes are separated by a certain distance, when they look at certain things, the images they see with their left eyes are different from those seen with their right eyes. It is this two images with different angles that make us feel three-dimensional after they are synthesized in the brain. The 3D image is also the same as this principle, and is composed of images shot with a special camera with the same effect as left and right eyes. The left and right images that were shot were sent to both eyes through 3D TV and glasses, and the three-dimensional images were synthesized in the brain so that we could see the 3D images. There are two ways to display images on a 3D TV: Shutter and Flash.


3D image imaging principle

TCL L43V7300A-3D uses Active Shutter 3D technology, English Active Shutter 3D, with active shutter 3D glasses. Active shutter 3D technology, also known as time division method shading technology or liquid crystal time-sharing technology, it is mainly achieved by the liquid crystal eyes, and its eyeglasses are essentially two LCD screens that can separately control on/off, in the eyes The liquid crystal layer has two states, black and white, which are usually displayed in white or transparent state, and turn black when energized. Through a signal transmission device, precise synchronization between the 3D eye and the screen is achieved.


TCL L43V7300A-3D adopts shutter 3D technology

Active shutter type 3D mainly achieves 3D effect by improving the refresh rate of the screen. By dividing the image into two frames, the two groups of screens corresponding to the left eye and the right eye are formed and displayed in a staggered manner. At the same time, the infrared signal transmitter The left and right lenses of the shuttered 3D glasses will be synchronously controlled so that the right and left eyes can see the corresponding screen at the right moment. This technology is able to maintain the original resolution of the picture and it is very easy for the user to enjoy true full HD 3D effects without degrading the picture brightness.


TCL L43V7300A-3D eyewear details

TCL L43V7300A-3D adopts active shutter 3D technology. This 3D technology is most widely used on TVs and projectors. It has relatively more resources and excellent image effects. It is highly recommended and adopted by many manufacturers. The TCL L43V7300A-3D is equipped with Full HD shutter-free eyes, which has many advantages in reducing image sticking. >>

5TCL L43V7300A 3D Picture Effect Back to Top

Six, TCL L43V7300A-3D native 3D screen effect:

The 3D image played this time is played by Sony Blu-ray player S470. Because the 3D image is formed by the difference in the distance between the left and right eyes, the blurry ghost image will only be seen when the 3D image is viewed without glasses. The 3D degree created by different scenes is also different, so the ghost image may not be correct. It will be very obvious.


TCL L43V7300A-3D 3D Effect Test (Naked Shot)


TCL L43V7300A-3D 3D effect test (shot under glasses)

Due to the active shutter 3D technology, brightness decreases when viewing 3D. However, on the current trial, the brightness does not bring about visual problems. On the contrary, when you take off the glasses, you will feel that the screen is too white.

TCL L43V7300A-3D 3D effect test (shot under glasses)

Although the TCL L43V7300A-3D uses a full HD non-flash shutter eye, it can reduce the flicker problem, but due to the performance bottleneck of the shutter 3D module, it can be seen that when the vision is deflected, the screen will change color, and the closer to the vertical, the more discolored the screen. Therefore, the user's best 3D viewing method still preserves the horizontal viewing angle.

TCL L43V7300A-3D uses shuttered 3D technology, the three-dimensional image is still very good performance, and the use of full HD shutter eyes, flicker problem is better than in the past to solve, but it can not eliminate the shortcomings of the shutter 3D - angular deflection Will bring about changes in color.

Seven, TCL L43V7300A-3D 2D 3D screen effect:

TCL L43V7300A-3D adopts shutter 3D technology and has more support for native 3D chip sources. However, the product also provides 2D to 3D functionality, providing users with seamless transition. By clicking on the "3D" button in the remote control, different formats can be converted. You can use the input source to select 3D conversion methods, such as normal 2D to 3D, left and right, and up and down.


TCL L43V7300A-3D 3D Effect Test (Naked Shot)

This audio and video is played by the Sony Blu-ray player S470, using 2D graphics, the film source is "Ip Man 2: Master Legend." Among them, we choose scenes based on characters to be more stereoscopic for people.
