Outdoor display computer settings without source bad, replace the outdoor display 2, check the power supply circuit 3, re-set. Outdoor display unit red (or green) Always 1 data lines connected to this unit, the corresponding allocation board, outdoor full color screen brightness to the problem of indoor full color brightness to 800cd/m2 1500 cd/m2 or more, in order to ensure the normal work of the screen, otherwise it will not see because of the brightness is too low outdoor display image displayed. The size of the brightness from the LED die is good or bad decision. The corporate philosophy --- a qualified corporate citizen of our company successfully developed a screen the revolutionary technology outdoor display (exclusive), can greatly improve the picture texture and give customers greatly reduce the integrated use of cost (the top screen effect, more than 50% energy saving, life expectancy doubled, maintenance-free).

RTYUII Hotline: 13684917757 the MO Hong Jin URL: http://www.Ltgd.cn/custom.asp?id=39 the size of the viewing angle display directly determine how much of the audience, and therefore the bigger the better. The size of the viewing angle is mainly determined by the die package. Knowledge of LED display, LED display works LED electronic display optoelectronic and computer technology in one high-tech products, LED display knowledge of the performance characteristics of LED products LED display of text and graphic LED display should have in moved out of the way and show the way prescribed in the detail specification. The main structure of the LED driver circuit using a flyback topology, control the Mosfet off by the control IC. This structure in the completion of a DC voltage supplied to the load while achieving a power factor correction, and completed the isolation of the load and power. Another task of the LED drive circuit is able under the influence of various factors can be controlled at the level of the pre-designed so that the load current of the LED. Electric outdoor display road will be a reference voltage or current signal Sref and the LED load voltage or current signal Sload fed to the signal control module compares the error signal after processing back to the primary control IC for processing, when the load current due to various factors change, the primary control IC can make the load current through the control switch to return to the initial design value. 2, washed with acetone and a small beaker with glue used. 3, prepare the required production specifications or contact list, and the corresponding model glue and confirmed in the effective use of the period. Start with glue: 1, with plastic order Description: the brighteners + A glue mixed proportionally (Order a one-time distribution), then add the phosphor + B glue objects (to be mixed in proportion Stir). Then vacuum. 2, calculated according to the ratio of production specifications or engineering memo phosphors and production quantities of various materials required weight. 3, four base adjustment precision electronic scales electronic scales were standards like outdoor display
