Just when many people were still excited and looking forward to the Apple iPhone being equipped with OLED, they found that there seemed to be a new term in this field, that is Micro-LED. In fact, even Apple seems to be planning. The rumored new Apple Watch has been rumored to be equipped with a Micro-LED screen, abandoning the original OLED technology. Since this year OLED is gradually becoming the mainstream, which we can most clearly experience when observing the TV market, and major manufacturers except Samsung have embraced this technology. In the smartphone market, a large number of new products, including domestic mobile phones, have also switched to OLED screens. However, the era of OLED has not yet officially begun, and people have begun to discuss Micro-LED, making the former seem like a transition. As early as last year's IFA exhibition, Sony exhibited its so-called CLEDis display technology, which is essentially what everyone calls Micro-LED. At that time, CLEDis impressed everyone very deeply. The ultra-delicate picture quality and vivid colors are pleasing to the eye. Apple is obviously also making efforts in this field, and its acquisition of Micro-LED display technology company LuxVue is already the best evidence. So for this possibility of ending the existence of OLED hegemony in advance, we can come to find out. Talk about Micro-LED We all know LED (light-emitting diode), and Micro-LED, as the name suggests, is a miniaturized LED. The core of this technology is to make miniaturized LEDs into arrays, transfer them to circuit substrates in batches, add protective layers and electrodes at last, and make them into display screens after packaging. If you want to ask what are the advantages of Micro-LED, it can be summarized as ultra-high pixel count, ultra-high resolution, lower energy consumption, and longer lifespan. Why is this so? First of all, we already know that Micro-LED is actually an array after LED miniaturization, that is to say, each pixel of it is a miniaturized LED unit. The LED chip millimeter level can be miniaturized to the micron level. At present, the general standard in the industry is about 50×50 microns, while Apple can achieve 10×10 microns. In this way, the spacing between pixels is very, very small, and you can imagine how delicate the picture is. According to calculations, if the iPhone 6-sized screen uses Apple Micro-LED, it can reach an astonishing pixel density of 1500 ppi, truly "invisible pixels". Another point worth noting is that because each pixel of Micro-LED can be individually addressed and emits light independently, coupled with the well-known high brightness of LED, Micro-LED screens can achieve ultra-high contrast and are very gorgeous. picture. As for energy consumption, OLED itself has more energy-saving characteristics because of the self-luminous characteristics of pixels. Since the pixels of Micro-LED can also emit light, it is naturally the same. Moreover, Micro-LED is more efficient and energy-saving. It is said that its energy consumption is 50% of that of OLED screen. In terms of lifespan, Micro-LED as an inorganic solution is naturally more durable than OLED, an organic-based solution. Micro-LED can achieve seamless splicing, so it has good adaptability to requirements of various sizes and shapes, and will not encounter too many challenges. These characteristics give Micro-LED a very broad prospect. Needless to say, the improvement of picture quality, as long as the equipment that relies on the display screen continues to develop, people's pursuit of better picture quality will not stop. Perhaps one day, the TV in our home will be able to achieve a picture as delicate as the painting in the living room. More importantly, since there will be no breakthrough in battery technology in a short time, it is very important to reduce the overall energy consumption of the system as much as possible. As a big consumer of electricity, the display screen can save a little bit from its mouth, not to mention that the theoretical energy consumption of Micro-LED is really good. challenges certainly exist Of course, if Micro-LEDs are all good, OLED will not be so aggressive. At least for now Micro-LED technology will be practical, we should still have to wait for a while. Just like all new technologies that have not yet been widely used, the biggest problems of Micro-LED are high cost, low yield rate, and difficulty in mass production. We just mentioned batch transfer, but in terms of transfer, there are difficulties in the process from sapphire substrate to glass substrate, especially the mass transfer of such micro devices. In addition, it is also difficult for LEDs to present consistent wavelengths after being cut from wafers into chips, that is, it is difficult to present colors. Therefore, Micro-LED may first be applied to wearable devices, such as smart phones, because such devices have small screens, low requirements for fineness, and relatively simple implementation. Another important point is that the LED array technology of Micro-LED is difficult to be flexible. Flexibility is one of the biggest advantages of OLED panels, and this application has a bright future. If Micro-LED cannot be used in flexible applications, the places where it can be used in the future may be limited by the applications we see now. In addition, although Micro-LED has many advantages, these advantages have actually begun to be challenged, such as PHOLED technology with better luminous efficiency, QLED with sufficient brightness and lifespan to pose a challenge, and so on. But in general, Micro-LED still has great potential, because all major manufacturers have already begun to lay out in advance, and some industry analysts say that it can be commercialized within three to five years. Because it is less difficult to realize, we may even see Apple launch an Apple Watch with a Micro-LED planar screen (Read A lot more) this year or next year. Compared with LCD and OLED, the progress brought by Micro-LED is very fascinating. Not only energy saving, but also a dramatic improvement in picture quality can be said to be very attractive. What's next for us? This is really exciting.

Glass curtain wall is a modern and fashionable architectural decoration, which adorns the city and makes the city more beautiful. The glass curtain wall LED display used with the glass curtain wall is even more sought after by the market. Its high transparency, invisible installation, green and energy-saving excellent performance make it stand out from many display products. So, how to make the glass curtain wall LED display achieve a better display effect? First, standardize the glass design. Glass is an important carrier for the installation of transparent LED display screens, and its size and shape directly affect the display effect of glass curtain wall LED display screens. When installing display screens with irregular and odd-shaped glass, not only the screen body needs to be customized, but also the cost is high; when designing the glass curtain walls of shops and buildings, owners should try to use glass with uniform size and reduce the use of special shapes , This can reduce the difficulty of installing the LED display screen on the glass curtain wall, reduce the keel, further improve the permeability, and make the screen display more transparent and beautiful. Second, choose the appropriate sharpness. Clarity is the resolution referred to in the industry, and it is also the loading point of the LED display. The clarity of the glass curtain wall LED display is mainly affected by its screen area and pixel spacing. The larger the screen area, the smaller the pixel spacing, and the higher the clarity. Owners can choose the appropriate definition according to the actual audience range and viewing distance of the advertisement to achieve economical and applicable effects. Again, brightness adjustment. Although the glass curtain wall LED display screen broadcasts advertising information to the outside world, it is essentially a type of indoor LED display screen and is installed in an indoor environment. Because outdoor advertisements require high brightness during the day, and low brightness is required at night, brightness adjustment is very necessary at this time. The conventional glass curtain wall LED display also uses a light-sensing probe and cooperates with related software to adjust the brightness, so as to ensure the comfort of tourists watching the screen, and then generate interest in the product and increase sales. In fact, there are still many ways to make the glass curtain wall LED display achieve better display effects. In life, everyone can pay more attention to store decoration and advertising effects, and make reasonable adjustments to achieve greater economic benefits.

The rotating outdoor led display screen is a new type of display screen that realizes graphic display by synchronously controlling the position and lighting state of light-emitting diodes (outdoor led display screens). Because of its novel structure, low cost, and a visual range of 360° It has been developed rapidly, and its core technology is to precisely control the synchronization of the position of the outdoor LED display and the luminous state. The display device of the rotating outdoor led display has only one column, and this column of outdoor led display is rotated by the outdoor led display with constant speed. Turning a certain angle, the display content of this column of outdoor led display will change once, and there will be a unique display content at any position when it is rotated, that is to say, the rotating outdoor led display screen is displayed column by column, and adopts A mechanical rotation is used instead of a scanning display. The principle of the rotating outdoor led display is not complicated, and its hardware structure is relatively simple, but to make the rotating outdoor led display able to stably display the set image or text, three technical difficulties need to be overcome: a. The rotating screen controls the power supply of the control circuit. When the system is working, the control circuit rotates with the rotor of the motor, so it is difficult to provide a stable power supply for the rotating control circuit and outdoor LED display. b. There is a problem of smearing in the horizontal display on the rotating screen. Since the rotating screen adopts a single-row outdoor LED display screen to rotate and scan to realize cylindrical image display, this makes the pixel display stick in the horizontal direction, forming a smear phenomenon. c. Solve the problem of insufficient display brightness. Due to the working principle of the electronic screen of the rotating outdoor LED display, compared with the ordinary flat outdoor LED display, it takes much less time to display each column, so the brightness will also be greatly reduced. In order to make the designed rotating outdoor LED display screen have a good display effect, these three problems need to be solved in the design. For the power supply of the rotating outdoor LED display, it is a relatively simple and reliable method to supply power to the system by contacting the brush plate fixed on the base and the rotating metal guide rail or metal wheel shaft. The design of this article is to provide a constant 12V DC voltage through the brush, and then convert it into 2.5V, 3.3V, 5V and other voltages by the DC-DC chip to maintain the control system. To solve the horizontal smear of the rotating screen, mainly according to the characteristics of rotating scanning, insert a black time gap between the two columns of pixels, so as to eliminate the stickiness of the two columns of image display points. To solve the problem of insufficient brightness display, the design of this article uses four columns of outdoor led video wall - view website, LED display lights to display each image on each rotating screen in turn without increasing the brightness of the outdoor LED display lights. prime point so that the brightness is quadrupled at the same rotation rate.
