This year we also got an upgraded version of this TV, the L5450C. This model uses a simple design and has a REGEZA high-definition engine and a native Android system with Google CTS authentication. The price of the 55-inch model is about 8,999 yuan. The current price of the Japanese 1080P product line has been significantly reduced this year, so this price is also considered mainstream.
basic configuration
The main specifications of the product are shown above. The configuration is similar to that of the current 1080P Japanese system. Although it is not the most popular on the market, it can also guarantee the application in most cases. In fact, the operating conditions of the Japanese aircraft have deteriorated in recent years. Therefore, the configuration we see so far is quite satisfactory and acceptable.
Toshiba L5450C real machine experience
Compared to many of the products we came in contact with, this TV has a lot of net importance. It looks like a very thin product. It weighs more than 25kg and it really takes a lot of time for the author to move it.
The backside design is also very simple. The nameplate shows that the product's origin is in Huizhou. As the smart module is also integrated in the TV, it looks slightly thicker.
Toshiba L5450C Configuration and Accessories
Summary: The configuration of this TV is relatively satisfying, active 3D eyes, wireless mouse control are very good additional features accessories. The overall workmanship of the product is consistent with the previous generation of products, and it is relatively neat, but it is not very outstanding. In addition, the installation of the product is very simple, and private installation is not a problem at all, but it may be possible to remove the product.
In addition, the details of the TV are actually in the out-of-the-box part of our experience, but it's OK. The interface configuration also belongs to a sufficient level; however, the design of the product is very simple, which seems to be not the same as other Japanese brands, and the author prefers a simpler and brighter design.
Toshiba L5450C color performance
Quality test
Finally to the quality evaluation stage, in fact, believe that many users have already seen impatience. We are simple, direct, and rude!
The overall rating is 7.5 points, and the rating of the quality part is about 7-7.5 points. It can be seen that the level of the picture quality of this product is considered to be slightly above average on the entire market.
Thanks to the use of new color analysis instruments, the current brightness and contrast levels are not as comparable to our previous test results, but the effect of these two values ​​on the image quality after reaching a certain limit It is difficult to perceive that when the brightness control requirement of the product is 200cd/m2, the central spot brightness will be slightly brighter, and the average brightness and the required value are not much different; in terms of contrast, the value of 1651:1 is already not low and should not become an influential picture. Quality bottlenecks. Below we analyze each item.
Color performance test
From the pixel point of view, Toshiba L5450C should use the VA panel provided by Huaxing Optoelectronics, and the value of the color gamut converted from the coordinate values ​​measured by the color analysis equipment reached 68.89% NTSC. This achievement is not prominent in the industry. However, it is better than other products using Huaxing Screen. This also fully demonstrates that the screen is not the only condition that affects the image quality.
On the other hand, from the perspective of the color gamut, we will see that the product's triangle and NTSC range will be different, and there will be non-overlapping areas in the blue part. This shows that the product's image quality engine is not strictly based on NTSC, perhaps in a certain In some places, it can display colors outside the NTCS specification, and of course there are some that cannot be covered.
Summary: Comprehensive test data and screen shot proofs, we can find the color reproduction performance of the L5450C is still good, although the color gamut value is near the 70% horizontal line, and the consistency test results are flat, but the color appearance of playback is also acceptable. The yellow skin of Asians and the white skin of Europeans and Americans have no obvious color cast. Just in accordance with the instrument test, the performance of yellow and blue will slightly deviate.
Toshiba L5450C light control and dynamic
Light control performance test
On the black screen, we used a longer period of high-sensitivity exposure to reflect the light leakage characteristics. Due to the use of a side-mounted backlight board, the light leakage around is relatively obvious.
Special light leakage is the characteristic of all liquid crystal products. This is common to liquid crystal display devices. It is also caused by the principle of liquid crystal display imaging imaging. We use a fixed exposure mode to expose the entire black panel to reflect different products. Leakage characteristics are only characteristics of the interpretation of the product, this does not mean that the product has quality problems.
Summary: This TV's light control performance in the same grade product if according to the fine difference in the four grades, I can give him a rating of "good", brightness uniformity and dark parts of the control are good, but fine Looking at the proofs, the level of the silk and background of the black-and-white clothing lady looks a bit unclear, which is consistent with the characteristics shown by the gray scale. In addition, the black charcoal part has a similar situation, although the black can sink, but the dark details are not abundant.
Optical dynamic performance test
Dynamic performance is not the strength of the VA panel. From the perspective of 100% magnification, through the small train window, the details of the scene opposite the rail can be seen, but it has been a little vague, so we gave a subjective score of 7 points. score.
Standard quality test summary: From the test results and standard test discs, we can see that the performance of the L5450C is slightly higher than that of its peers, not to mention that the picture quality of the L5450C is lower than that of the Japanese classics. The overall performance is acceptable, let's take a look at the screen shots of the test video.
Toshiba L5450C screen shots and summary
Screen shot proofs
The color and dynamic properties of the proofs above are consistent with our objective evaluation. The strengths of the picture are relatively moderate saturation and relatively accurate color performance. There is no excessive rendering to maintain the features of the original picture, but not Will definitely please the eye. For example, the author prefers colorful images; in addition, the dynamic performance is flat and the definition of the moving picture needs to be strengthened.
Toshiba 55L5450C summary
From the picture quality evaluation, we can see that the picture quality level of Toshiba L5450C is comparable to that of L5350C, with little difference. However, the L5450C integrates the smart module into the body, which undoubtedly enhances the friendliness of the product.
The analysis of advantages and disadvantages above shows that for a Japanese machine with a listed price of RMB 8999, this price is relatively modest. If we are full of quality to buy it, we think it is not pure enough, and if you intend to have a picture quality can also be a smart machine, Toshiba L5450C or worth considering.
