Sharp LCD-70XU30A is the first 8K effect TV, so what's his 8k effect? Let Xiaobian take you to find out next!
Sharp LCD-70XU30A quality test
In the picture quality evaluation, we adjusted the display parameters of the TV to the system default, and used the least interference to restore the most essential content. The evaluation room used a professional instrument to test and score the product in five aspects, and made a five-dimensional performance chart, as shown in the above figure.
According to the results of the evaluation, the Sharp LCD-70XU30A NTSC color gamut measured as high as 115.26% of the horror (according to the internationally accepted CIE 1976 color gamut standard, there may be a certain error due to the test environment), the new wide color gamut technology The newly-developed new phosphor LED encapsulates red and green phosphors in blue LEDs. The purity of the red and green colors is greatly improved compared to a conventional TV. At the same time, a four-color panel with yellow subpixels is added. Both complement each other and achieve the industry's highest level of color reproduction. Thanks to the "New Color" technology, smart adjustment and supplementation of the backlight, this TV has reached a very high level in terms of contrast and brightness.
As an 80-inch 8K-definition TV, the power control performance is very surprising to the author, less than the average power consumption of 200 watts is not easy, Sharp's meticulous set-up of the hardware has just reached the point where everything is in full swing.
The test results show that the color gamut of Sharp LCD-70XU30A reached 115.26%. From the perspective of the color transition, the color transition is relatively natural, and there is no obvious wiring between the three color transitions. It can also be seen from the macro-point diagram of the pixel in the lower left corner of the figure that Sharp displays two luminance information in each horizontal and vertical direction of one pixel, which improves the 4K resolution by a factor of four and realizes 8K resolution.
In order to ensure the authenticity and stability of the data, we conducted many tests on the Sharp LCD-70XU30A at this stage. The results of each test are also quite consistent: the test instruments are all qualified. The brightness uniformity can be seen from the table data in the figure is very ideal, the color consistency is also very beautiful.
In the silk standard test screen, we can see that the color reproduction of Sharp LCD-70XU30A can be quite good, the color is soft and natural, the different shades of color in the same color can also be well distinguished, there is no color cast, details The characterization is also very delicate.
In the yarn ball test screen, we mainly look for whether there is a bond area between the right and bottom yarn balls. From the above test screen, basically all colors can be well restored, the middle blue plush ball and There is almost no adhesion between red and pink in the lower right corner, and no color cast occurs.
In this part of the color test, Sharp LCD-70XU30A demonstrated the advantages of the ultra-wide color gamut TV brought by its four-color technology panel. The screen is colorful, with high saturation, and the color reproduction is accurate and undistorted. With such color performance, the author could not help giving it. Out of 9.5 points high score.
Light control performance test
In the brightness test, we turn on the color technology and use the default brightness value. This brightness looks more natural. Through the real shot screen can be seen Sharp LCD-70XU30A white screen performance is very good, the picture is clear and detailed, all kinds of white and gray are very well distinguished. Based on Sharp's "New Color" technology, the peak brightness has reached 1328cd/m2, and this result has been excellent in 4K TVs, not to mention 8K resolution TVs.
Grayscale performance, from the test screen, all levels of gray can be distinguished, the most difficult to distinguish the 0 ~ 1 segment can also be a little distinction, visually legible.
When the surrounding environment is completely black, when the television picture is adjusted to be completely black, the degree of light leakage is directly observed with naked eyes, which is the most direct judgment that the calibration of the television panel is excellent. When I turn off the evaluation room light source, as shown in the figure, it is exactly the same as closing the TV. Sharp LCD-70XU30A has perfect performance in the control of the panel light. The screen is all black and there is no light leakage problem!
to sum up:
Sharp LCD-70XU30A has excellent light control capabilities, strong black and white images, and dark details that can be well preserved. Sharp's "New Color" technology is not only a localized light control technology. The traditional local light control technology is a bright part of the image, turning on the backlight, the dark part of the image, turning off the backlight, thereby increasing the contrast. The “New Color†technology first analyzes the self-luminous and reflected light in the brightness part of the image, and at the same time with the backlight control, the backlight power that has not been completely turned off is transferred to the turned-on backlight part, and the backlight part of the open part is further improved. brightness. Not only is the partition control the backlight on and off, but it can also increase the brightness of the backlight in the open part, which further enhances the contrast level of brightness and darkness. This shows that such excellent performance is still active.
