Once upon a time, the appearance of the modeling competition became the selling point of many brand manufacturers, and they all spared no effort in the design of the base, backboard and sound. I do not know which array of spring breeze blowing, minimalism has become the standard for each manufacturer's design.

TCL D55A830U follows the simple design standard and adopts a very narrow frame design. The front end only has the bottom "TCL" logo embellished. The main circuit board is concentrated in the plastic shell on the back, and the overall thickness of the fuselage is only 9.9mm at the thinnest point. .

2 screen performance test: "color", "bright" double back to the top

Screen performance test: "color", "bright" double

In a nutshell, when we first saw the pre-sale price of TCL D55A830U, it was natural to associate the price with quality. The performance requirements for its image quality were naturally not too high. After all, one penny and one goods, after several screens. After the test, the author has a new understanding. The gamut value and the brightness value performance are beyond the expectation of the author, and the overall rating is 8.5 points. Don't ask me why? Look at the various tests.

Power performance test

TCL D55A830U power test data test item red green blue black and white color transition power consumption results 119.45w 119.71w 118.62w 117.90w 119.55w 120.31w

Power consumption performance, through the playback of different photos of pure colors, recording the power consumption value of TV, from the above table can be seen that TCL A830U power control is very good, not only with this screen, but also with the TCL later screen calibration Ability has a positive correlation.

Color performance test

From the gamut test chart in the above figure, the TCL A830U performs under the full color gamut chart. The transition between colors is very natural, and the saturation is also high, but the green part is relatively weak and the color richness is much less. Macro point of view of the pixel point of view, it is indeed RGB true 4K panel, pixel is 4 times the full HD, to avoid the grainy image display, more abundant picture details.

As can be seen from the above figure, the TCL D55A830U TV test NTSC color gamut values ​​as high as 100.48% (13.6% for the BT.709 color gamut standard), is a true wide color gamut screen, particularly prominent red display capabilities, yellow performance is also relatively The previous television is even better.

The green display capability does not have a color transition display. The main reason is that the TCL A830U uses a high-gamut backlight scheme, which uses a high-purity new red-green powder, and the use of enriched filters, a substantial increase in the color gamut of the screen. The value makes the color layering better and also makes up for the short board on the green display. Visible on the screen of the factory calibration ability, TCL is still full of confidence.

In the silk standard test screen, the overall picture color of the TCL A830U is more realistic, and the different shades of color in the same color system can be well distinguished. There is no color cast, and the details are very delicate.

In the actual drawing of the yarn ball, we mainly compare whether there is a bond area between the red and pink in the lower right corner. It can be seen that the boundary between the yarn balls of various colors in the screen shot is very clear, and no obvious color deviation occurs. The color from the dark part to the bright part is also natural, and the saturation of the color is high.

Gray scale test found that from 0 to 15 continuous changes from black to white, you can see the overall performance of TCL D55A830U is very good, no matter whether it is the 0th shadow or the 15th light, the boundary between each level is very clear. This is also an advantage brought about by the high brightness value, to minimize the color of the picture.

In the black and white standard test screen, we can see that the TCL D55A830U's black and white screen performs quite well. In the Tokyo Tower, the sky is sinking, and there is no light leakage. The darkness of the middle billboard is clearly distinguished. In the black and white dress lady test screen, the lady in white dress is in the same color background, and its silk contour is clear and the level is very clear. The sleeveless part of the black dress is a bit blurry. In the charcoal part, the charcoal lines on the side are not very clear and can only be discerned. It needs to be strengthened.

High-speed dynamic picture test

Many consumers are keen on sci-fi and action movies, and their screens often change dynamically at high speeds. This also imposes requirements on the dynamic performance of television screens. In this test session, they are seen through the train window through the enlarged views. Whether the scene on the other side of the train is clear to determine the merits of its dynamic performance, from the real shot of the TCL D55A830U screen, the edge of the house is very clear, through the window, the outline of the silhouette of the car is clearly visible, and not because of high speed The phenomenon of smearing or blurring occurs.

From the test results and standard test discs can be seen, TCL D55A830U dynamic test performance is satisfactory, in the same price level products, its performance is absolutely at a high level, maybe a picture is not convincing, let us take a look at other screens Make a sample.

Summary: TCL D55A830U in terms of picture quality, with 100.48% NTSC ultra high color gamut record, yellow and red display performance is very prominent, with its high color gamut backlight program to enhance the clarity of the TV and Color expressive ability, to avoid loss of image details or grainy, more rich levels; dynamic performance, dynamic rendering HDR technology, adjust the brightness and darkness of the TV source, so that the picture details are well preserved.

3 Technical Highlights: HDR+ High Color Gamut Back to Top

Technical highlights: HDR+ high-gamut backlight

High-gamut backlight solution

The liquid crystal itself does not emit light, and the image needs to be displayed by the light of the backlight. Therefore, the color gamut of the liquid crystal television is mainly affected by the backlight. Now mainstream LCD TVs use white LED backlights. The light emitted by them is not pure enough, and the range of color gamut displayed is naturally very low. TCL D55A830U choose to start from the backlight, from the root to effectively enhance the color range.

TCL D55A830U different traditional TV backlight program, using the third generation of high-gamut backlight, which uses a high-purity red and green powder and enriched filter combination, so that the purity of the backlight is higher, to improve the color gamut of the TV, a more realistic reduction Every color on the screen. Of course, it is not enough to have a pure backlight that can present a wide color gamut, but also has excellent color control technology. The TCL A830U TV is equipped with TCL's exclusive precision color gamut control technology to effectively increase the color gamut and improve the overall performance of the screen.

Full ecological HDR solution

This year's color TV industry hot words, ultimately "HDR" figure, first solve these professional vocabulary is what ghosts, HDR English full name is called High Dynamic Range, translated to call the high dynamic range. The display of high-dynamic-range images of televisions depends on the range of brightness and darkness of the television display. HDR is a picture with a wider and richer picture performance between the brightest and darkest. HDR is actually "high contrast."

Due to problems such as light and jitter, the photos under static photography are often distorted. The TCL A830U solves this problem through a full ecological HDR technology, which fully enhances the gradation and details of the photos, bringing clear dark details and a good sense of depth.

Summary: In the shooting, production, transmission, display and other aspects of the image must meet the HDR standard, to achieve content, hardware, software to fully meet the HDR standard, showing a real HDR image effect, from the screenshots, in a poor light environment, Whether it's sparkling on the lake or charcoal in the fire, its details and light and shadow effects are all excellent, allowing consumers to see more details on the screen.

Pull Wire Encoder

Displacement sensor, also known as linear sensor, is a linear device belonging to metal induction. The function of the sensor is to convert various measured physical quantities into electricity. In the production process, the measurement of displacement is generally divided into measuring the physical size and mechanical displacement. According to the different forms of the measured variable, the displacement sensor can be divided into two types: analog and digital. The analog type can be divided into two types: physical property type and structural type. Commonly used displacement sensors are mostly analog structures, including potentiometer-type displacement sensors, inductive displacement sensors, self-aligning machines, capacitive displacement sensors, eddy current displacement sensors, Hall-type displacement sensors, etc. An important advantage of the digital displacement sensor is that it is convenient to send the signal directly into the computer system. This kind of sensor is developing rapidly, and its application is increasingly widespread.
