WS28 13 is a new patented product launched by Shenzhen Huacaiwei Technology Co., Ltd. in 20 16. It is an upgraded product based on the previous WS28 12S and WS28 12B. Combined with years of market application feedback experience, it has the following remarkable characteristics:

1 ... only 5mm*5mm in size, and the shape is the same as that of 5050 lamp beads. Each element is a pixel with built-in LED driver IC and almost all peripheral components. The circuit is simple. Compared with WS28 12 series products, it greatly reduces the occupied area of peripheral components and reduces the damage rate in the application of flexible products. Because the general light bar is used in a harsh environment, the light bar is easy to bend, and the previous products are easy to bend, which leads to circuit disconnection and pixel damage. The innovation of highly integrating all peripheral components is of epoch-making significance and makes the product easy to use.

2. The breakpoint continuous transmission function is added, which is the biggest breakthrough. Because in engineering application, due to different factors, it is inevitable that individual points will fail and be damaged, which makes the subsequent points unable to be displayed normally. In addition, in use, the harsh environment may also lead to individual point damage. WS28 13 solved this big problem, and added an additional signal line to realize two-way signal transmission. Any damage will not affect the cascade transmission of signals, and other pixels will display normally. WS28 13 If individual points are damaged in use, the overall display effect will not be affected at all.

3. Power supply reverse connection protection. The power supply was accidentally connected during the installation. If there is no power supply reverse connection protection, the whole light bar may be short-circuited and damaged. WS28 13 can solve this problem by adding reverse protection of power supply, which is convenient for installation and use.

4. The reset time is as long as 250us, which is convenient for engineers to control the program. The control protocol is completely compatible with the circuit board, which greatly reduces the cost and is convenient to use.

5 .. Up to 2khz RGB port refresh frequency. High-definition display screen standard, the three primary colors of each pixel can achieve 256 levels of brightness display, complete the full-color display of the colors in 167772 16, and there will be no stroboscopic when taking pictures with high-definition cameras and moving dynamically.

Main application fields:

1..LED full-color luminous character light string, LED full-color soft light bar and hard light bar, LED guardrail tube.

2..LED point light source, LED pixel screen, LED special-shaped screen, etc.

I try my best to help you.
