Products unit board, also known as LED display module is the main component of the display unit, the LED light-emitting diode and driver circuit. 08 interface 12 interfaces each pin of the LED unit board 08 interface G2, R2 product attributes common interface (eight) ABCD G1 G2 LS 16 1 NNNO R1 R2 NN 1512 General Purpose Interface (xii) 2 ABCSLRGD 16 1 ONNNNNNN 15N = ground (GND), L = Latch (LAT or ST), S = Clock (Clk), O = the can (OE), E = Enable (/ OE) R = red data, G = Green data, U = blue data, A, B, C, D = line signal, H = the decoded row signal, F = vacant, V = VCC08 interface G2, the role of R2: use no matter which interface, one of the R or G signal with the 16 lines of data, 08 interface G1, R1 on the line 16 data, G2, and R2 is the next 16 lines of data. In other words, 08 interface can output 32 rows of data, while 12 interfaces only 16 lines. Tips LED unit board interfaces 08 and 12 two interfaces: 08 Interface ABCD G1 G2 LS 16 1 NNNO R1 R2 NN 1512 interface 2 ABCSLRGD 16 1 ONNNNNNN 15 units board and control cards commonly used symbols Mark explained: N GND - the COM is negative flag VCC + V + are a sign of the positive electrode L = latch (LAT or ST), S = the clock (CLK), O = enable (OE), E = enable (/ OE) R = The red data, G = green data, U = blue data, A, B, C, D = line signal, H = the decoded row signal, F = vacant, the pixel pitch of the display screen by the main features of the V = VCC) LED P, the pixel pitch, meaning the same as in the dot pitch of the CRT (dot pitch), which is the point spacing. Pitch generally refers to the distance between the adjacent two pixels on the display. The picture we see is formed by a number of points, while the delicate degree of quality is determined by the dot pitch to dot pitch calculated based on panel size divided by the value of the resolution obtained. The general led display P4/P5/P6/P7.62/P8/P10, behind the figures to show that the distance of the pixel spacing unit is mm, so P6, is led display dot pitch of 6mm. Note triple significance, is the one led lights, three led lights are red R / green G / Blue B, this package, three colors led several together, mixing effect is better; while a three-fight, forty-three 0805/0603 led and emissions with; other full-color unit board module manufacturers in Shenzhen, Holley flag manufacturers supply special, full-color unit board wholesale, inexpensive detail to inquire! Transactions that can be customized to a variety of products, can contact us asking for more information!
