Why is it black—Looking at the new advantages of Nationstar display device packaging from the 1010 full-color series
With the boom of the LED display market, people's requirements for the display are getting higher and higher. It only took a few years to go from a display that could only transmit text information to a full-color display with pictures and texts. These not only intensified the industry competition of LED display devices, but also brought great challenges to the packaging technology of LED display devices. The most important thing about making a good display screen is to please people's eyes, so factors such as resolution, color reproduction and even brightness all affect people's intuitive experience. From the perspective of display devices, it is specifically reflected in technological breakthroughs in packaging materials, device size, appearance, optoelectronic parameters and reliability.
In order to make the LED display screen have more delicate picture quality, especially for indoor displays, smaller-sized LED devices are required. Currently, the indoor full-color small-pitch 1010 series launched by Nationstar Optoelectronics is already at the forefront of the industry. The 1010 series LED devices have not only achieved breakthroughs in small spacing, but more importantly, have greatly improved image quality. In order to present a more vivid picture, the screen needs appropriate brightness and high contrast. The brightness is related to factors such as the number of LEDs per unit area, the brightness of the LED itself, and the driving current. High contrast can better display vivid and rich colors. The popular understanding is the ratio of the brightness of a single pixel on the screen when it is the brightest and the darkest. For practical use, it is impossible to place the entire screen in a dark room environment to test its brightness when it is completely dark, so the darkest brightness can be replaced by the brightness reflected when the display is not emitting light, that is: the brightness when it is emitting light is higher than the brightness when it is not emitting light (reflected brightness).
As an ultra-small size CHIP LED full-color device, Nationstar Optoelectronics 1010 series has the advantages of small size, moderate brightness and high reliability. The display effect is comparable to that of an LCD screen, making it the best choice for indoor small spacing. Not only that, Nationstar Optoelectronics has successfully developed a unique "black" process with years of accumulated R&D strength, which makes the packaged LED device appear black and reduce the reflected brightness. Therefore, it shows the unique performance of soft light, large light-emitting angle and good consistency.
To achieve this breakthrough is not as simple as "turning black". It is not only necessary to minimize the impact on the luminosity of the LED itself, but also to avoid the degree of reflection on the surface. The breakthrough of this process is to avoid the discomfort of long-term viewing caused by glare. In addition, because LED displays have extremely high requirements for heat dissipation, the thermal conductivity of epoxy resin, as the main packaging material, is very unsatisfactory and is not conducive to heat dissipation. The "black" process can not only improve the contrast, but also effectively improve the thermal conductivity of the packaging resin, making the entire display screen more effective and reliable, thus extending the service life of the LED.
Not only that, Nationstar Optoelectronics continues to make technological breakthroughs and product updates in small-pitch LED devices. More importantly, it brings us inspiration. It can be predicted that through the improvement of packaging technology, high-resolution, high-contrast small-pitch LED displays are just around the corner. This makes small-pitch LED displays shine in applications in high-end conference rooms, command and control, video surveillance and other fields.
