View Distance The image perception is influenced by the distance between the viewer and the LED screen. The ideal viewing distance is 1x ~1.5x the pixel pitch in meters. So in a 12 mm pixel pitch screen it is around 12 meters. At this distance the human eye (or brain) no longer sees individual pixels but the whole picture. Of course you can get closer (and certainly further away) watching the screen. Closer to the screen the pixels will become increasingly evident, but the image will no long remain acceptable. The viewing angles for an LED displays are measured horizontally and vertically, and indicate over what range images on the LED screen are fully visible without the screen displaying a negative image.The viewing angle of a LED display represents the limit of its optimal picture quality. Sit at a position at a wider angle than that of its viewing angle and you will experience worse picture. The LED industry defines viewing angle as the full angle at which brightness is half of the brightness from dead center. (The view angle of a screen is by convention the angle within which the brightness of a display is equal to the 50% of the frontal luminosity.).More scientifically, if ø (angle theta) is the angle from off center (0°) where the LED’s brightness is half, then 2ø is defined as the full viewing angle. For example, a LED screen with 5000 NIT frontal brightness has a visibility angle equal to the angle by which the brightness is reduced to 2500 NIT. This visibility angle can vary depending on the LED and the technical features of the display. In conclusion, it can be stated that loss of brightness under viewing angle start with radiation characteristics of individual LEDs. In most cases radiation characteristics of LEDs show 50% brightness level at about 60°. If the viewing angle of the LED screen becomes lower, the LED screen brightness will be higher, or vice versa. If the contrast ratio between LED screen's brightness and environmental brightness is higher, the led screens’ showing performance will be more colorful. But a too high brightness will consume a lot of energy and create high heat. For that the LED's brightness decreases much faster, and of course, its lifespan will become shorter.

LED displays promise to change the way movie and television productions are created, but the effects are only as good as the video walls on which they’re shown. Those displays are constantly improving. Just a few decades ago the pixel pitch, or the distance between individual pixels in an LED display, was in the range of 12 mm, making them suitable primarily for viewing from a distance. Today, the pixel pitch of some displays is in the range of .6 mm or smaller, making them comparable in resolution to an LCD display. Although that shrinking pixel pitch has greatly improved the resolution of the displays it does create challenges that need to be overcome to make them suitable for video applications. Concerns that need to be addressed when using LED displays in video productions include: Brightness Adjustable screen brightness For different scenarios, the brightness of screen is needed to adjust to meet requirements. Refresh rate Refresh rate at high brightness – According to the “10 times refresh” theory, the refresh rate for high brightness LED displays needs to be more than 10 times the camera shutter speed for images taken by the camera to be free of lines and defects. A typical camera has a shutter speed of about 1/200 second, so the refresh rate of an LED display in a broadcast application needs to be greater than 2,000Hz or bright lines will appear in the image. Most fine-pitch LED displays today use PWM-based driver chips, which have the characteristics that the refresh rate at low-grayscale levels is lower than that at high-grayscale levels. As a result, when showing a low-grayscale image on the LED screen black streaks appear on the picture taken by the camera, greatly affecting the visual experience. Grayscale The loss and discontinuity of pixel data at low grayscale levels greatly reduces the smoothness of images, causing them to appear unclear to viewers. There are two causes of this problem. The first is that the grayscale data of the video source is compressed. This leads to a loss of a certain amount of grayscale and is likely to cause blocky images. The second is that the grayscale output bit number of the LED display is too low. Therefore, the jump span of each level at low grayscale is too large, thereby causing discontinuity. HDR If the LED display has a higher grayscale output, such as 16-bits, it can decrease discontinuity problems and lead to a better visual performance. Viewers can see more details, especially under low brightness conditions. In addition, when the video source is HDR, an LED displays would perform better with 16-bit grayscale output and a higher refresh rate. This kind of opulent image quality will bring a photorealistic performance making it well suited for movie backdrop use. Contrast Insufficient contrast causes a loss of image detail and results in images without multiple layers, similar to a painting ...

SMD, COB, and GOB are the packaging technologies for LED. This article was written by Tony Tong of Huasuny, and first published in linkedin. 1. What is SMD LED? SMD is short for Surface-Mounted Device. SMD LEDs are a type of LED technology where the LED chips are mounted directly onto a printed circuit board (PCB). The design of an SMD LED typically consists of three primary components: the LED chip, a phosphor coating, and a small reflective cavity. 2. What is COB LED? COB is short for Chip-on-Board. This type of LED technology involves mounting multiple LED chips directly onto a single substrate, creating a unified light-emitting surface. 3. What is GOB LED? GOB is short for Glue-On-Board. GOB LEDs are a type of LED technology that uses transparent glue to cover the entire surface of the SMD LED display modules. GOB is an upgraded version of SMD. ROUND 1: Reliability 1. Artificial knocks and collisions: In actual applications, it is difficult for the screen to avoid external force collisions during transportation and handling, so anti-collision performance has always been a major consideration for manufacturers. As high-protection display module technology, the protection level of COB and I also varies. COB directly solders the chip to the circuit board and then fills it with glue in one piece; while I first encapsulate the chip in the lamp bead, then solder it to the circuit board, and finally fill it with glue in one piece. Compared with COB, there is an extra layer of packaging protection, and the anti-collision ability is better. 2. External forces of the natural environment: Using epoxy resin with ultra-high transparency and super thermal conductivity as the glue-filling material, I can achieve true moisture-proof, salt spray-proof, and dust-proof to be suitable for more harsh environments. ROUND 2: Display effect COB has risks in separating wavelengths and colors and picking up chips on the board, making it difficult to obtain perfect color uniformity for the entire display. Before I perform special gluing, I will manufacture and test the module in the traditional way consistent with ordinary modules, avoiding color difference, moiré, and other defects in light and color separation and obtaining good color uniformity. We regard a single LED pixel/module as a rose. ROUND 3: Cost Theoretically, the manufacturing cost will be lower because the material composition process is less and the required materials are less. However, since COB adopts whole-board packaging, it must be passed once in production to ensure that there are no bad pixels before packaging; the smaller the point spacing and the higher the precision, the lower the product yield. It is understood that the current COB normal product shipment rate is less than 70%, which means that the overall manufacturing cost will also have to share an increase of about 30% of hidden costs, and the actual expenditure is much higher than expected. As an extension of SMD technology, I can i...
