Before the implementation of the LED stage leasing display display project, it is necessary to make a design plan, especially when the LED stage leasing display screen body should be considered, the important factors such as the LED display model, display content, installation site environment, cost, and ensure production must ensure production. Process and technical indicators such as technical indicators are suitable for actual application needs of indoor, and it is reasonable to design it.
1. Stage lease LED display point spacing
The sense of visual granules mainly comes from the human eye to have a certain resolution. Watch two points at a certain distance. When two points are close to a certain degree, the human eye will not be able to distinguish. With the improvement of the LED display manufacturing technology in the past two years, the resolution of the small -pitch LED display body has been continuously improved. The indoor LED display design has been upgraded from the smallest point distance specification scheme to select the appropriate point distance specification scheme.
The pixel distance is the distance between the lamp beads. For example, the pixel spacing of the P3LED display is 3mm; the minimum visual distance is the distance of the pixels without the eye, but the long -term viewing of this distance will damage the vision; the best vision is watching the LED LED The comfortable distance of the display screen is also the clearest distance; the pixel density is the LED display screen clarity indicator. The larger the value, the higher the high -definition; the full HD image video, the screen of the screen 16: 9, the human eye vision is the best.
Through analysis: P1.27, P1.54, P1.6, P1.9, P2.5: LED stage rental screen, which is a small spacing LED display (point spacing below 2.5mm). The minimum visual distance and the best vision are very close to the viewing requirements of large tablet TVs. The entire screen resolution is as high as 4800 × 2400. It can display clearer screens on the same LED display screen body, but display on a 12M wide screen. A high -definition signal needs to be magnified by 3 to 4 times, showing that the two high -definition pictures need to be zoomed in; at the same time, high -resolution display requires high -performance image processing equipment, and the overall cost of the system will be high. P4, P4.8 specifications cannot display two high -definition pictures at the same time on the 12M wide screen, and cannot meet the high -definition conference TV screen display requirements. P3 can meet the requirements of two high -definition pictures at the same time. According to the size of the display screen, the high -cost P3 is finally selected as the display point of the project's main screen and auxiliary screen, and the P4 is selected as the display point of the label screen.
Second, packaging technology
One factor that determines the quality of the LED display is the main material, such as chips, brackets, glue (epoxy resin), golden lines, etc. Another factor is the packaging process. Pixel packaging technology is related to the color saturation, perspective and other display effects and production costs, quality stability of the entire LED display, etc., which is one of the very important indicators to choose the LED display.
The mainstream packaging technology of the indoor LED display is mainly DIP and the SMD mode. The direct -inserting module is to encapsulate the glowing tube to grow up, and then the three tubes of traffic orchids are made into a pixel dot module together, and it is directly inserted on the PCB board to weld. The process is relatively simple, the cost is low, the bad point rate is high, , Mainly applied to outdoor display. The table stickers refer to the encapsulating luminous pipe on the circuit board, and then process the integrated circuit welding process into a screen body. It has good heat dissipation and uniform color. The entire display can be maintained positively, which greatly reduces the maintenance cost and difficulty. At the same time, the filling metal compound is performed during the packaging process.
The three -in -one table sticker refers to the three luminous points encapsulation of the red, green, and blue in the same luminous pipe. It is a little bit. It is mainly used for production of high -density high -end small spacing LED display.
