Face-to-face vs. face-to-face vs. Internet TV
In 2014, curved screen televisions such as cyclones began to sweep the market, but are curved screens so beautiful? The editor thinks this is not the case. Even though LCD TVs do not have a sense of embracing, they have a mature technology and good image quality. However, theory of light alone is not enough. There are exactly 2 televisions in the evaluation room, one of which is facing directly and the other is curved TV. The two are all well-known Chinese brand products. The following may wish to pass the test to see who is better at surface and face TV.
The front-facing TV in the exterior design comparison evaluation room is a product newly launched by a well-known TV brand in China. It was also exhibited in the home exhibition of the previous days. It has a 55-inch LGD original IPS panel with a physical resolution of 3840x2160. Belonging to LG's latest 4-color 4K Air panel, the screen performance is more breakthrough than the previous products.
The right side of the table is also from the famous, size 55, physical resolution 3840x2160. In terms of basic parameters, the two TVs are basically the same. The appearance of the part of the benevolent eyes, the face of the panel represents the traditional LCD TV style, curved screen represents the direction of development in the other direction.
The side of the fuselage, the right side of the TV is very thin, measured its thickness is about 7.5MM. The left side of the curved TV I'm sorry, counting the body thickness of 40MM, even the thinnest place has 17MM, in terms of body thickness, curved screen defeated.
As for the design of the appearance itself, the difference between the two is not great. Just curved screen because of the body surface, coupled with the X-type bracket used to stabilize the body, so it looks very occupied, if placed on the wall of the desktop, it is undoubtedly face TV to save space. Front and rear space occupied by the curved surface is quite powerful. If the living room and the room and the table are not very big, you really need to consider whether or not you need a curved surface TV. Face to face TV does not have this problem, the test machine is used is the most common two metal stent designs, put aside its own electroplating chromium process, in terms of structure is very simple and provincial place.
Picture theory performance comparison test
The screen measurement is based on the spider 4 professional color correction instrument. Through this device, the screen output color of the television and the display device can be detected at zero distance, and the color performance capability of the television can be expressed in the most real and accurate manner.
According to the results of professional equipment scanning in color performance, the color gamut of the TV facing surface performed well. The SRGB color gamut was 100%, and the Adobe RGB color gamut for printing and design was also 78%. The performance was excellent. The color TV on the right side of the surface is equally impressive. The SRGB color gamut is 100%, and the Adobe RGB color gamut is less than 77%. The gap between the two is small.
In this test, the brightness of the face-to-face television is relatively average, 50% brightness is slightly lower than the maximum brightness, the maximum brightness exceeds the standard of 250, and reserve brightness is sufficient for the TV. Contrast performance is quite satisfactory. The contrast of the surface TV is relatively out-of-spectrum, with the maximum brightness of 426 but the middle brightness is as high as 313, which indicates that the brightness control is obviously insufficient and may be related to the high center brightness of the curved screen after being bent.
In terms of color accuracy, the two TVs performed well. The right side of the TV's color rendering capability is more accurate and the degree of deviation is not large. The right side of the surface deviation of the color deviation is very large, especially in gray and color, there are serious deviations, indicating that the color distortion is obvious.
From the local brightness control test point of view, the brightness uniformity of the left straight face is better, the deviation value is very low, indicating that the control light performance of the panel is good. The performance of the curved TV on the right is more general. It is also a 4K panel product. Its light control capability is very mediocre, and the middle and upper parts are effective, but the lower part of the curve is far off the mark.
Detailed picture comparison test
Compared with the same picture, the curved TV doesn't support color adjustment in USB mode, so one of the two TVs has 50 brightness and 50 contrast and 50 colors, and the curved TV is not set directly.
From the perspective of the screen, the overall appearance of the curved TV is relatively bright, while the face color of the TV is elegant. In terms of the level of the screen TV is much better, the white and blue parts of the seaside are better than the surface, and the blue part of the latter is full.
From the bottom left detail view, you can see that the curved screen TV renders the white building reddish, and the face TV does not have this problem. In general, the color accuracy of this curved TV is very general, which is the result of the previous screen test. Consistent.
Look at another picture, this is the original screenshot of 4K video, 2 TVs are also read in USB mode. As you can see from the photos, the curved screen TV on the left is warm in color and the right TV on the right is cooler. The color of the surface TV is obviously oversaturated, and the color of the skin is similar to that of drinking the Erguotou. Although the overall color of the TV on the right is flat, the color of the collar is relatively positive. From the previous color test, it can be seen that there is a serious distortion problem in the curved TV. The center of the TV is white, but the distortion is much smaller, especially when the red color is the most accurate. The color of the collar is enough to prove .
Curved TV is really good?
The insufficiency of the test surface quality of the curved TV is reflected in the serious unevenness of the screen brightness. In addition, the light control has obvious deficiencies. For example, when the 50% brightness is set, the measured brightness far exceeds the middle value, and the lighting control in the lower 3 areas is also Showing a great degree of deviation. In terms of color accuracy, as described previously, the colors are not perfectly correct, and even the blue sea becomes dark blue, and the white building becomes red and white, which actually affects the experience. Of course, in addition to the problems of the panel and the driver circuit itself, the physically complete curved screen itself is also a major cause.
According to panel supplier LGD, current LED-backlit TVs, with the exception of OLED TVs, are based on physical means of bending, which can cause the panel to distort and disrupt the ability of the phenomenon. The OLED is a native light and has a good bending performance, so it is most suitable for curved TV.
If personal feelings are concerned, it is not entirely a good thing to experience surface TVs through this comparison evaluation. Surface TVs are not as good as TVs in many projects, especially the key color expressions that are exposed by curved TVs. Insufficient control, lack of color and other issues really a lot. In other words, at least before the popularity of OLED native lighting, the traditional face-to-face TV's display performance is even more outstanding. At the present stage, it is more worthy of selection than the curved surface TV.

It has a 55-inch LGD original IPS panel with a physical resolution of 3840x2160. Belonging to LG's latest 4-color 4K Air panel, the screen performance is more breakthrough than the previous products.
The surface effect is not obvious from the front
The right side of the table is also from the famous, size 55, physical resolution 3840x2160. In terms of basic parameters, the two TVs are basically the same. The appearance of the part of the benevolent eyes, the face of the panel represents the traditional LCD TV style, curved screen represents the direction of development in the other direction.
The difference in thickness shows an overwhelming superiority in face-to-face television
The side of the fuselage, the right side of the TV is very thin, measured its thickness is about 7.5MM. The left side of the curved TV I'm sorry, counting the body thickness of 40MM, even the thinnest place has 17MM, in terms of body thickness, curved screen defeated.
Curved TV stands take up space
As for the design of the appearance itself, the difference between the two is not great. Just curved screen because of the body surface, coupled with the X-type bracket used to stabilize the body, so it looks very occupied, if placed on the wall of the desktop, it is undoubtedly face TV to save space. Front and rear space occupied by the curved surface is quite powerful.

Gamut performance test gap is not large
According to the results of professional equipment scanning in color performance, the color gamut of the TV facing surface performed well. The SRGB color gamut was 100%, and the Adobe RGB color gamut for printing and design was also 78%. The performance was excellent. The color TV on the right side of the surface is equally impressive.

Brightness contrast test
In this test, the brightness of the face-to-face television is relatively average, 50% brightness is slightly lower than the maximum brightness, the maximum brightness exceeds the standard of 250, and reserve brightness is sufficient for the TV. Contrast performance is quite satisfactory. The contrast of the surface TV is relatively out-of-spectrum, with the maximum brightness of 426 but the middle brightness is as high as 313, which indicates that the brightness control is obviously insufficient and may be related to the high center brightness of the curved screen after being bent.
Color accuracy test surface TV distortion
In terms of color accuracy, the two TVs performed well. The right side of the TV's color rendering capability is more accurate and the degree of deviation is not large. The right side of the surface deviation of the color deviation is very large, especially in gray and color, there are serious deviations, indicating that the color distortion is obvious.
The visual manifestation of color distortion is that the overall color of the curved TV is not correct, and the brightness and contrast of the center are too large, resulting in the bridge in the picture appearing somewhat whitish.
Local Light Control Test Surface TV Outrageous
From the local brightness control test point of view, the brightness uniformity of the left straight face is better, the deviation value is very low, indicating that the control light performance of the panel is good. The performance of the curved TV on the right is more general. It is also a 4K panel product. Its light control capability is very mediocre, and the middle and upper parts are effective, but the lower part of the curve is far off the mark.

Real Screen 4K Wallpaper
From the perspective of the screen, the overall appearance of the curved TV is relatively bright, while the face color of the TV is elegant. In terms of the level of the screen TV is much better, the white and blue parts of the seaside are better than the surface, and the blue part of the latter is full.

From the bottom left detail view, you can see that the curved screen TV renders the white building reddish, and the face TV does not have this problem. In general, the color accuracy of this curved TV is very general, which is the result of the previous screen test. Consistent.
4K video picture real shot
Look at another picture, this is the original screenshot of 4K video, 2 TVs are also read in USB mode. As you can see from the photos, the curved screen TV on the left is warm in color and the right TV on the right is cooler. The color of the surface TV is obviously oversaturated, and the color of the skin is similar to that of drinking the Erguotou.

Curved TV is really good?
In terms of visual perception, the surface and face TV are not too different. Curved TVs have a certain degree of environmental protection, and this feeling is more obvious when watching movies. But on the screen quality, the curved TV is not as good as the tested screen TV. This is because the existing LED-backlit liquid crystal curved televisions are bent by physical means to achieve a bending effect, which results in a physical irreversible effect on the screen, and the final quality of the display is also slightly inferior.
The insufficiency of the test surface quality of the curved TV is reflected in the serious unevenness of the screen brightness. In addition, the light control has obvious deficiencies. For example, when the 50% brightness is set, the measured brightness far exceeds the middle value, and the lighting control in the lower 3 areas is also Showing a great degree of deviation. In terms of color accuracy, as described previously, the colors are not perfectly correct, and even the blue sea becomes dark blue, and the white building becomes red and white, which actually affects the experience.

Comprehensive scoring
If personal feelings are concerned, it is not entirely a good thing to experience surface TVs through this comparison evaluation. Surface TVs are not as good as TVs in many projects, especially the key color expressions that are exposed by curved TVs. Insufficient control, lack of color and other issues really a lot. In other words, at least before the popularity of OLED native lighting, the traditional face-to-face TV's display performance is even more outstanding. At the present stage, it is more worthy of selection than the curved surface TV.
