QLED TV

The concept of Quantum Dot or QD has a fairly extensive interpretation in physics. But the marketers of large corporations are pleased to apply this complex scientific concept to promote their products.

Operation principle

A quantum dot is a microcrystal with the properties of a semiconductor. Its electrical properties depend on the size and shape. The point must be very small for the manifestation of quantum effects. These effects depend on the size and material of the microcrystal. Simply put, the energy of the emitted photon depends on the quantum point size. These small particles light up in a certain range when illuminated. Dependence of the emitted color on the size of the microcrystal became the basis of the technology for the development and production of a new generation of TVs, which are called QLED TVs. The diagram illustrates the operating principle of this technology.

The first model of this TV, called SUHD TV, was introduced by Samsung at CES 2015.

The first S letter symbolizes Spectacular, Smart, Stylish and Superb. A thin layer of microcrystals is located on a thin film. Its illumination is accompanied by a bright glow. The size of microcrystals and, accordingly, the emitted color is easily controlled, providing a very accurate color rendering. The TV contains white backlight, color filters and a liquid crystal matrix. Color filters divide the glow into red, blue and green. The matrix looks like a grid with tiny windows (pixels). In turn, the pixels consist of three subelements (cells). Liquid crystals act like shutters. They can block the flow of light or, conversely, completely skip it. In addition, the crystals can retain an intermediate state.

Formation of white color

White light is emitted by LEDs and passes through a pixel with two closed cells (for example, red and green). In this case, the person sees a blue color. The degree of participation for each RGB-pixel varies. Thus, a color image is formed. The color rendering quality of the image depends on the precise operation of the light filters and the quality of the white backlight that should have a fairly wide range. But the light of LEDs has a very narrow spectrum. In addition, it's actually not white. Some technologies provide expansion of the range to a white color. For example, phosphorous diodes with the addition of yellow color are used more often than other technologies. However, such a quasi-white color also does not provide the optimal range. Sunlight is divided into all the colors of the rainbow of equal intensity when passing through the lens. Many remember this experiment at the lessons of physics at school. But the spectrum of the quasi-white color has an uneven intensity. For example, the red color is much weaker compared to green or blue. Of course, engineers are trying to solve this problem. For example, the green and blue levels are reduced to equalize the intensity levels in the TV settings. However, this reduces the overall brightness and the image becomes paler.

A white light source that provides a uniform spectrum of colors with the same intensity across the entire range is the ideal solution to this problem. QD technology can solve this problem. Today, many consumers when buying a TV prefer QLED models, which are cheaper compared to OLED panels with similar image quality. In 2018, Samsung introduced the new QLED Q6F, Q7F and Q9F 4K UHD HDR TVs. Features of the new Samsung Q6F can be viewed on this video. Read the full article

笔记本摄像头被忽视了！厂商为何“不思进取”？

2015年以前，笔记本摄像头位于屏幕上方正中间，无可撼动；CES2015上，采用三面微边框的XPS13惊艳亮相，为了给微边框和DELL Logo让路，摄像头被移到了屏幕左下角。

MWC2018上，华为展出MateBook X Pro，摄像头地位进一步降低，来到键盘上；同年9月，华硕旗下子品牌a豆笔记本13发布，直接没有摄像头。

这就是笔记本摄像头的地位，从高到低，从低到无。

我在2018年初写了一篇关于笔记本摄像头的文章（点此查看），认为笔记本摄像头“食之无味弃之可惜”；智能手机的崛起加速了笔记本摄像头没落；笔记本厂商不思进取，祖传720P（约92万像素）用到现在也不换，隔壁智能手机都能拍银河了。

一年前的文章是一吐为快，并没有谈到笔记本摄像头为何“不思进取”，今天想和大家聊一聊这个问题。

被忽略的重要因素：厚度

现如今没有几个摄像头不突出的智能手机，大家已经司空见惯。智能手机…

Quantum dots technology in TV

Of course, the technology of quantum dots has become one of the most significant innovations in the segment of television matrixes. It was developed by Samsung company. Samsung Electronics first introduced the QLED TV with this technology at CES 2015. It got the name SUHD TV, where the first letter symbolizes Spectacular, Smart, Stylish and Superb. Despite the ambitious title, demonstrated TV is quite consistent with this title.

Engineers predict that this technology will reduce electricity consumption by 5 times. In addition, they expect a longer service life compared to OLED TVs. Companies also claim that they will be able to reduce the cost of production by 2 times compared with OLED TVs and LED display. Today, the sub-pixel size of the display is about 50 microns in width and 10 microns in length. Such a compact size opens up wide prospects for using this technology in the production of screens for mobile phones.

Operation principle

Quantum dots are microscopic crystals that glow under the influence of light or electricity. Crystals can glow in different colors. The color depends on the size and material of the pixels. The diagram demonstrates the operation principle of this technology that is based on the dependence of the emitted color on the dimensions of the crystal.

Today, scientists have learned to almost completely control the size of quantum dots by changing the number of atoms. Thus, the technology can provide almost unlimited color gamut. Additionally, quantum dots are very stable. Therefore, for example, a point of a certain red hue retains its color a very long time. Today, engineers use this technology as follows. A solution with microcrystals or quantum dots is applied to a silicon wafer. Rubber matrix with a comb surface is gently pressed against this surface to capture microcrystals. Then they are separated for application to glass or to flexible plastic. Strips with microcrystals (quantum dots) are used for the production of thin-film transistor matrices. Such a coating is created for different shades, for example, for a glow with a certain shade of red and green. Microcrystals are mixed on a single film without separation into auxiliary pixels. In the future, they emit red and green for backlight, for example, of a conventional blue diode. Mixing the three primary colors provides an ideal source of white light.

The high quality of white light behind the matrix is almost equivalent to the natural color rendering for the viewer's eyes on the other side of the screen. The color rendering quality is increased at least due to lack of correction with losses or distortions for the spectrum. A wide color gamut is ideal for 4K TVs and 4: 4: 4 sub-colors.

Conclusion

Of course, Quantum dots technology will improve the color reproduction and overall impression of the image. However, this technology does not solve other problems of LED TVs. For example, it does not provide an ideal black color, because liquid crystals are not capable of completely blocking light. The color only weakens in the intermediate state. OLED technology and plasma TVs completely interrupt the flow of light. However, plasma TVs are practically taken out of production, and OLED-TVs are still too expensive for most consumers. Therefore, QLED TV is a good choice for many consumers when buying a TV. This video demonstrates the new Samsung Q90R 2019 Flagship 4K QLED TV. Read the full article
