Tft Lcd Displays In Medical Equipments.MiniLED screen era? If you have ever bought products such as a tablet or monitor, you will find that when choosing a screen, everyone pays more attention to parameters such as screen resolution, refresh rate and response time.
In fact, for the display screen, color accuracy, color gamut, color correction and other aspects are also very critical, especially for users with creative needs and higher requirements for audio-visual entertainment, the display effect of the screen will directly affect the experience of use. For example: the display screen is not bright enough, the contrast is not bright enough, yin and yang screen. The emergence of these situations is related to the form of backlight used by the display.
At present, most of the monitors in the market are using LCD technology, which is what we call liquid crystal display. As a transparent display device, LCD needs backlight to provide the required brightness. The form of backlight is divided into side-type backlight and direct backlight.
To put it simply, the side-in is to arrange the LED light strip on the four sides of the screen, this form is doomed that the backlight can not be evenly distributed in all parts of the panel, resulting in uneven screen, brightness or color.
Direct backlight, as the name implies, is to place the LED light source at the bottom of the screen for more uniform light and higher dynamic contrast.
LCD technology is more than that, the full array backlight developed on the basis of direct backlight, with more LED beads to divide more areas, so as to achieve more accurate and meticulous local light control. In recent years, the LED lamp beads used as LCD backlight have shrunk again and again, reaching between 100m and 200um (only equivalent to the diameter of a hair). In this way, more backlight beads can be integrated on a screen, thus controlling the color and brightness of each subtle part of the screen more accurately. That is, we are going to talk about miniLED today, and its arrival has injected fresh and energetic blood into LCD technology and even the entire display industry.
There is no doubt that miniLED is now the “pet” of the industry. San’an Optoelectronics has supplied miniLED chips to Samsung in bulk, while BOE plans to mass produce miniLED-related products in the fourth quarter of this year. TCL Huaxing also has thousands of lamp beads miniLED panels used in terminal products. MiniLED was used in Apple’s recently released iPad Pro, and recently, Huawei’s e-sports display also uses an miniLED screen. MiniLED higher brightness, richer colors and other new features, can show a ultra-high level of display, well received by users. Unfortunately, Apple’s iPad Pro, which currently uses miniLED, faces some technology-related problems that have led to a delay in the release of the new product.
Although everyone has begun to actively lay out miniLED, it still faces technical bottlenecks and screen costs, and it will take some time to popularize. The good news is that HKC, a technology innovation company that has been focused on display panels and has strong R & D and production capacity, has also laid out miniLED early.
