LED Display Screens Technology Concerned in Movie and TV Production
Oct 16, 2024 LED Display Screens Technology Concerned in Movie and TV Production
This Article was wroten by Tony Tong, the sales manager of Huasun, and initially published in Linkedin. 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 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 without depth an...

GOB VS COB for LED screen Technology
Oct 08, 2024 GOB VS COB for LED screen Technology
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...

Huge sucess in Infocomm 2024
Jun 19, 2024 Huge sucess in Infocomm 2024
We had a huge sucess in infocomm 2024 which held at Las Vegas Concention center June 12-14. We broght our newly developed rotating led poster that linked to display together which attracted a lot of attentions. Our newly develop rental use flexible transparent led display give the customer another choice when selecting the transparent led display. Not only does our display IP65 rated, offers 4500nit brightness, but also it is very easy to splicing into different shape. In our booth, we easily spliced a wave shape screen. which attracts many customer Our newly develop raptor, also give customer a new concept of building a curve led display. Different from the traditional flexible led display that we need to change the curving angle manually. with our Raptor, we can change the curving angle using electric pluse. which make the angle more precise, and also make the installation process more easy and elegant.
