With the development trend of micro-pitch displays, 4-layer and 6-layer boards have been adopted. Printed circuit boards will use micro-via and buried-hole designs, printed circuit pattern wires will be fine, and micro-holes will be narrowed. The mechanical drilling technology can no longer meet the requirements, and the rapidly developing laser drilling technology will meet the fine hole processing.
With global energy shortage and environmental pollution, LED display screens have a wide application space due to their energy saving and environmental protection characteristics. The application of LED lighting products in the lighting field is attracting the attention of the world. Generally speaking, whether the LED lamp works stably and with good quality is very important for the heat dissipation of the lamp body itself.
We know that the point-to-point image display effect is the best. After reducing the image, if only ordinary graphics processing technology or general FPGA graphics processing algorithm is used, the edges of the image will appear jagged, and even pixels will be missing. The brightness will also decrease. High-end image processing chips or FPGA systems that use complex graphics processing algorithms will maximize the display effect of reduced images.
This design not only saves the
packaging cost, but also improves the reliability of the product. It has been
widely used in outdoor LED display products. The SAM (Scanning AcousTIc
Microscope) was used to test the airtightness of the LED bracket with the
folded structure design and the normal bracket. As a result, it can be found
that the product with the bent structure design has better airtightness. View More >> LED tools
The production process of the PLCC stent mainly includes the steps of die cutting, plating, PPA (polyphthalamide) injection molding, bending, repair, and five-sided three-dimensional inkjet. Among them, plating, metal substrates, plastic materials, etc. occupy the main cost of the bracket. This design not only saves the packaging cost, but also improves the reliability of the product. It has been widely used in NovaPro UHD Jr.
With the Vdwall LVP7042 4k Video Splicer increasing display area of LED small-pitch products, projects of dozens of square meters are common. The physical resolution of LED displays often exceeds 1920 × 1200, that is, each ultra-large-scale LED display consists of several It consists of several independent display areas driven by each LED controller.
