Fourth, Sharp LCD-60X50A color technology trial
As Sharp's flagship product this year, the most important feature of the Sharp X50A series is the addition of the Huang Cai technology. According to official sources, Huang Cai Technology is based on Quattron's four-color technology. However, its essence is the area control technology of the direct-type LED backlight system, that is, the processor controls the brightness of the backlight in real time through image brightness and darkness information. Huang Cai technology can put the power of the dark part of the image into the bright part, so that the contrast of the screen is strengthened, and the power consumption is also reduced.
The official Huang Cai effect image contrast
We chose the common PS3 user interface and the fireworks screen in the movie "Creation Warrior" to compare the color technologies. They are high-grade and closed screen shots of the two states, but it may be because the users' display devices are not It's the same, so the picture is not as obvious as when it was actually viewed.

In the fireworks scene of the movie, it can be seen that the bright part of the fireworks and the black background are more obvious after the opening of the Huangcai technology. The bright parts of the fireworks display are more translucent, and the background purity is also higher, and the picture color is restored more accurately. >>
Six, Sharp LCD-60X50A 3D principle analysis
At present, there are many ways to realize 3D video viewing, which can be mainly classified into naked-eye type and glasses type, among which the naked-eye type raster display method and holographic display method are difficult to achieve, and it is expensive and hard to popularize. Spectacle type is divided into color separation method, light division method, time division method and other technologies, color separation method is the earliest and cheapest 3D technology, but easy to cause color cast, 3D effect is also the worst; light division method that is high school textbook introduction The polarizing 3D technology is better than the color separation method, but the screen is difficult to achieve full HD resolution, brightness is relatively low; time division method is also known as active shutter 3D technology, most current first-line TV manufacturers use this technology, have no effect The advantage of the picture effect is that the glasses are heavy and expensive and some of the pictures have a flickering effect.
Sharp 3D principle analysis of LCD-60X50A
Sharp LCD-60X50A is using active shutter 3D technology, the principle is this: the screen will be displayed to the left eye to see the screen, then the glasses will cover your right eye simultaneously, a bit like pirates wear goggles. Then, the screen will quickly switch to the right eye. At this time, the glasses will turn to cover your left eye and make sure that the picture you see is correct. This process alternated very quickly, reaching 120 times per second, so it was impossible for the human eye to see this shift.
Sharp 3D principle analysis of LCD-60X50A
A pair of active shutter 3D glasses, model AN-3DG20-B, was included. Compared with Sharp's previous generation 3D TV LV925A series glasses, this 3D glasses will further reduce the circuit part, the temple part is as light as ordinary glasses, thus making the wearing effect more comfortable.

Compared with the polarized 3D technology, most of the foreign brands currently use active shutter 3D technology. This technology can guarantee the sharpness of the picture while realizing the 3D picture, and Sharp has also used many techniques to improve this problem for crosstalk and flickering. 3D glasses with active shutter technology are also being made as light as possible. >>
Seven, Sharp LCD-60X50A 3D screen effect
As a mainstream feature of the current high-end machines, we have also conducted some trials on Sharp's LCD-60X50A 3D screen. Xiao Bian will now perform 2D and 3D screen captures of similar clips in playback to compare the differences between 2D and 3D screens, especially the two major differences between depth of field and brightness.
Sharp LCD-60X50A 3D Effect Test (Naked Shot)
Sharp LCD-60X50A 3D effect test (photographed through glasses)
The 3D video played this time was broadcast by Blu-ray player BD-HP90 which was sent by Sharp at the same time. 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.
Sharp LCD-60X50A 3D Effect Test (Naked Shot)
Sharp LCD-60X50A 3D effect test (photographed through glasses)
In terms of brightness, because the Sharp X50A uses the loss frequency to achieve 3D functions, there is a certain loss of brightness when watching 3D images. However, in the actual viewing, although the brightness is lost, but does not affect the viewing effect, Sharp also provides a special 3D brightness adjustment function in the image settings to meet different viewing needs.
Sharp LCD-60X50A 3D Effect Test (Naked Shot)
Sharp LCD-60X50A 3D effect test (photographed through glasses)
In active shutter 3D technology, the phenomenon of flicker and crosstalk has been a major technical problem. The Sharp X50A also uses many technologies to avoid these phenomena, such as high-speed liquid crystal technology, FRED (3D display high-speed liquid crystal drive technology), LED backlight scanning technology. In the final analysis, these technologies are all aimed at improving the response speed of TVs and reducing the problem of image sticking. In practice, crosstalk is not serious, but watching 3D glasses for a long time does increase the burden on the eyes.

Sharp X50A also has a 2D to 3D function, you can choose the way to convert 3D through the input source, such as ordinary 2D to 3D, SBS left and right formats, TAB up and down formats. Xiao Bian after testing that although the effect is not as good as native 3D, but this feature is still a certain degree of practicality, in the current 3D film source is not much, the use of this feature to taste fresh is not bad.

Sharp LCD-60X50A 2D to 3D effect (naked eye shot)
In the active shutter 3D technology, the relationship between the angle of the glasses and the screen is very important. Therefore, when viewing the 3D movie, it is necessary to maintain a substantially horizontal angle to view a clear and bright 3D image. This is also true on the Sharp X50A. It can be seen through the rotating glasses that the brightness loss is severe when deflected to a large angle, and the image is completely invisible at 90 degrees.
3D glasses deflection angle visual effect
After a small series of tests, Sharp LCD-60X50A is very good in 3D depth of field construction, although the brightness of the image will be darkened with the eyes, but by adjusting the 3D brightness can solve this problem. The image crosstalk problem is not easy to detect, but based on the technical principles, there will still be a slight flicker when watching 3D images. Although it does not affect the viewing, the glasses may feel tired after a period of time. >>
Eight, Sharp LCD-60X50A gray scale comparison test
Since the screen shot has undergone the necessary software processing and is affected by the actual effect of the netizens' display, the screen displayed on the screen will eventually differ from the actual effect of the TV. Therefore, the actual effect is based on the author's text description. I use the Hi-Definition Reference Disc test disc. The equipment used was a Canon 50D and the Canon EF-S 18-200mm f/3.5-5.6 IS.
Sharp LCD-60X50A 15 Gradient Grayscale Test
The first test is a 15-gradient grayscale test. From the actual screen, Sharp LCD-60X50A has a very good grayscale performance, and dark and bright parts can be easily distinguished.
Sharp LCD-60X50A Charcoal Black Level Test
In the black gray-scale tolerance test, the Sharp X50A handles the dark part of the image very well, the details of the dark parts of the charcoal are clearly visible, and the black part can also be interpreted to be in place. At the same time, the details of the highlights were not too bright, and the performance was very good. I believe it was related to the author's opening of the color effect.
Nine, Sharp LCD-60X50A color performance
First, Xiaobian uses DisplayX to perform full-gamut color transition tests on the Sharp LCD-60X50A. It can be seen from the figure below that the screen color of Sharp LCD-60X50A is full of vision, but the transition in the yellow-green and red-yellow color areas is abrupt, and the other color transitions are all in good condition. I believe this is related to Sharp's Qili technology. .
Sharp LCD-60X50A full color domain color transition test
Although the performance of some color transitions is general, it can be seen in the picture of the rotating cloth selected by Xiao Bian that the Sharp X50A is very good in the performance of various colors, with saturated colors and clear edge details.

By observing the Tokyo Tower image, we can examine how the Sharp LCD-60X50A performs in a high-contrast scene. On the screen map, the details of the highlights and dark parts of the Tokyo Tower can be clearly displayed, indicating that the TV is excellent in contrast.
Sharp LCD-60X50A High Contrast Scene Test
From the above tests, it can be seen that Sharp LCD-60X50A has a significant transition in grayscale performance, and the interpretation of details in the shadows is also in place. While in the full color gamut color transition, Sharp X50A is somewhat blunt in the transition of red, yellow, and green, but it is relatively accurate in terms of color performance. It can be said that the four-color technology and the huangcai technology all add points to the interpretation of these images. . >>
Ten, Sharp LCD-60X50A dynamic screen test
In this part of the test, you need to pay attention to what the netizens are paying attention to is the car behind the windows of the fast-moving train and the body plates of the car. The author used the same ISO and aperture during the shooting process. The parameters are ISO-400 and F4.5. The exposure time is 1/100 seconds. Sharp LCD-60X50A uses the intelligent speed control 100/120Hz + Aurora speed 100/120Hz double speed processing technology, but also equipped with a high-speed liquid crystal technology, FRED (3D display high-speed liquid crystal drive technology), LED backlight scanning technology these are Reduces the number of effective image-ghosting techniques.
Judging from the effect of the moving train, the phenomenon of house ghosting in the train window is relatively slight and the dynamic effect is satisfactory.
