LED Display System requirements

LED Display System requirements 02,985,453,602 Display Screen Display Module 4.1.1 Display module by 128 pixels, each pixel includes two red and one green LED tube LED tube and a blue LED. It can display full color Ba Lu Qi Qi Lu Qi Jiu San Lu wantonly colors. Center pixel and pixel pitch of 20mm, pixel density of about 2500 / m2. P20 module as shown in Figure P16-1: P10 module front view P10-1 Figure 4.1.2 unit cabinet unit box assembly is the basic unit of the display must be installed to ensure accuracy, flexibility can be assembled and Removing the structure. The company therefore display unit cabinet quality cold-rolled steel plate, the use of digital equipment and laser positioning means bending press forming, improve machining precision, box processing error is less than ± 0.5mm; steel box after acid wash, phosphate treatment and further conducting paint, both inside and outside the cabinet so that the same corrosion preventive capability; P10 unit cabinet front view P10-2 Figure 4.2 Power Systems Screen Built-in AC-DC switching power supply for the display portion power, under specified conditions (50Hz ± 2Hz, 220V ± 15%) with output stability, high reliability and no-load, short circuit, overheat protection and so on. Each box mounted six 5V40A switching power supply is rated at 1200W, the average power of about 400W. 4.3 Control system of the display control system uses Linsn control system has the following characteristics: Gigabit technology; by-point correction, by card (cabinet) correction function; smart identification card function; refresh rate be set, lock synchronization function; double large load area; twin cable hot backup function; multi-screen synchronization and combination of features; voice transmission function; the program online update feature; breaking the traditional concepts no DIP switches; long transmission distance. Intelligent connectivity; intelligent monitoring; support any scan mode within 16; support module 64 within a width of an arbitrary number of; supporting shaped split display; support capacity than point insertion; support driver IC with PWM; support hardware-by-point correction ; support-by-point detection by the control computer control system, the system sends the card, the system receives cards. 4.3.1 computer applications and peripherals
