Image quality performance test
Toshiba 65U6680C comprehensive quality demonstration
Image quality is the essential demand of TV. Toshiba U6680C TV adopts REGZA image processing technology and HDR technology, which makes TV have very good performance in color, dynamic, and light control.
Quality test data
Toshiba 65U6680C PConline quality test data test project NTSC color gamut center brightness average brightness color depth response time test value 78.476% 271cd/m2 259.78cd/m2 10bit 8msPower test data

123.05 121.63w 115.47w 125.31w 124.87wColor performance
From the perspective of the color transition, the color transition is also very harmonious and natural. From the pixel point of view, Toshiba U6680C uses a Samsung 3 color 4K panel, compared to other brands on the market to promote the 4 color 4K panel, the color is more true. In the spectrum diagram, the color transition is natural, there is no hard, no color fault, and the color is very saturated.
From the instrument test data, Toshiba 65U6680C brightness uniformity is very good, thanks to its full direct type LED backlight design, brightness and light efficiency have a great advantage, very good to avoid the brightness of the side-entry backlight does not all.
The rose mainly shows the expression of color between different colors. It can be seen that the flowers of various colors are very rich. Each color has a high degree of saturation and it is very seductive.
Through the color analysis equipment test, the color gamut value obtained by measuring the coordinate values ​​of the three primary colors of red, green, and blue has reached 78.476% NTSC. Thanks to the Toshiba REGZA image processing technology used by the Toshiba 6680C. Make up for the defects caused by low color gamut such as distortion and color cast, making the color more vivid.
In the red fruit picture, whether it is the red apple or the dark red of the strawberry, or the bright red of the small tomato or the purple of the grape, although the same color system, the red of different dark gray levels is accurately expressed. It is not because the colors are too similar and there is no obvious color cast resulting in color cast.
Light control performance test
In the brightness test session, we will first turn the backlight on to the brightest, and other parameters default to see the light control performance of the TV under the standard maximum backlight conditions. Toshiba U6680C average brightness reached 259.78cd/m2. The test screen shot can be seen in the scene of the overall gray screen, the overall picture is very sharp and clean; from dark to light, the details of the different levels of grayscale performance are very good, higher screen leveling.
The grayscale graph test was slightly disappointing. From the brightest to the darkest graded changes, the Toshiba U6680C black color scale was slightly blurred and it was not easy to identify the level of the superior rank.
There are exquisite transitions between black and black clothing and black backgrounds in the cat and woman test screens. In the chess board, the black and white contrast between the chessboard and the chessboard is obvious. Thanks to Toshiba U6680C HDR dynamic light and shadow technology, it not only allows the screen black to sink, but also makes the white glossy.
Dynamic performance test
In terms of dynamic performance testing, far beyond the author’s imagination, when a train traveling at a high speed is seen from a distance, the number of the train and the details of passengers on the train can be used to demonstrate the advantages and disadvantages of TV dynamic performance. The Toshiba U6680C's screen shots show that the train number "2816" is very sharp. Red passengers in the windows can also see clearly, and there is no phenomenon of smearing or blurring due to high-speed advancement.
We found two very perverted videos to test the dynamic performance of this TV. The 24-frame picture moves quickly. The Toshiba U6680C's high refresh rate and dynamic response speed result in accurate interpretation of the picture. The effect of watching the game is also very good, the picture is clear and smooth, there is no phenomenon such as smear out of frame.
Interpretation of featured multimedia functions
Rocket Sound Effect
In terms of sound quality, Toshiba U6680C is equipped with a rocket sound to reproduce high-fidelity sound quality while reducing power consumption. The original bottom-mounted sound system design makes the sound interpretation more accurate and full of layers, and is very powerful.
The remote control has a key to turn on the rocket sound. When you are watching a movie or listening to music, pressing it can turn on or turn off the rocket sound.
Toshiba U6680C Rocket Sound Audition
The test of the sound of the speakers is a very subjective subject. The author found the “California Hotelâ€, which is often used by fans to test HIFI, to test the Toshiba U6680C. The Eagles' "California Hotel" is called the audio of the Divine Quality Test. In the prelude, two guitars are played. Not only the melody is beautiful, but also the rhythm and flexibility are very strong. It reflects the analysis of the sound very well. In the song, Audience cheers, applause, singing by the singer and playing by the guitar are the test sound field.
For the performance of this song, the Toshiba U6680C performed very well on soft vocal and quivering guitar melody when the rocket sound effect was not activated. The surround sound surround of the stereo was very strong, and the expression of the bass drum in the second half was not. simply. After the Rocket sound effects were turned on, the bass drums performed very cleanly, without dragging, and the sound's extensibility was greatly improved. The overall performance of the sound field is large enough to give people a broad feeling, not repression, high-frequency part will not give people a harsh feeling, there is no pop noise or feeling too loud.
HDR dynamic light shadow
HDR, also known as high dynamic range technology, finds an optimal performance band between the bright and dark parts of the picture, making the bright detail of the overall picture brighter and the darker part darker. HDR is applied to mobile phones in the early days. However, HDR is required for TVs. Of course, it is not as simple as migrating directly. It depends on the brightness and darkness of TV displays.
Here we compare the performance of the Toshiba U6680C in HDR video playback by comparing several screen shots (the source parameters are: HEVC, 10bit, BT.2020, HDR10).
The "Fantasy Rafting by the Young School" movie clip, Toshiba U6680C is clearly more prominent in brightness, brightness level, and color, while the ordinary LCD TV underneath is covered with a layer of fog. The whole picture is chaotic and has low brightness. The level does not stand out.
"camping" video clips, the overall TV screen is generally dark, the girl's clothing outline, barbecue details, the contours of the kerosene lamp dark details have been lost, can not be presented. In the Toshiba U6680C, the performance is very clear. There is a good sense of layering between the near and far objects on the screen. It keeps the current environment dark and shows the details as much as possible to better reflect the visual effects of people in the real environment. .
Toshiba uses 4K dynamic light and shadow HDR technology, through chip analysis through technical analysis and adjustment of the TV's source brightness and dark parts, optimize the contrast so that the brightness range closer to the perception of the human eye, and then through the processing of REGZA image engine eventually on the TV show HDR After the 4K screen.
