显示器数据线的接法=标准15针 vga头焊接（Connection of display data line = standard 15 pin VGA head welding method） 显示器数据线的接法=标准15针 vga头焊接方法(Connection of display data line = standard 15 pin VGA head welding method) Connection = standard 15 pin VGA welding method of display data line The method of display data line VER 1 The VGA pin (pin definition display data line) VGA pin definition VGA 15 pin female socket 15 pin male plug VGA?? VGA is Video Graphics Adapter (Array) abbreviation for analog signal type type. The commonly used computer simulation of signal interface: VGA interface and RGB interface The VGA pin definition interface (too small if you click on the picture to enlarge to see) Pin Definition One Red red Two Green green Three Blue color blue Four Address code ID Bit Five Self test (the different definitions) Six Red Seven Greenland Eight Blue Nine Keep (the different definitions) Ten Digital ground Eleven Address code Twelve Address code Thirteen Line synchronization Fourteen Field synchronization Fifteen Address code (the different definitions) The standard 15 pin VGA welding method: The standard 15 pin VGA pin head as shown below (3+4 line, 3 said the 3 coaxial red, green and blue, 4 said 4 pieces of black and brown and yellow and white) VGA feet usually follow obtrapezoid, from top to bottom, from left to right are 1 - 5 feet, 6 10 feet, 11 feet, 15; (note that the D15 joint must use metal shell) as shown below: We usually need only 15 pin 11 pin welding can be as follows: (4, 5, 9, 12 feet welding) The red line "1" foot analog signal "red"; The green line "2" foot analog signal "green"; The blue line - "3 feet" - "blue analog signal"; The red line shield line - "6 feet -" red "analog signal ground wire shield; The green line outside the shielding line - "7 feet -" green "analog signal ground wire shield; The blue line shield line - "8 feet -" blue "analog signal ground wire shield; Black - "10" - the number of sub foot signal of the ground terminal; The brown line - "11" - foot between the screen and the host control or address code; The yellow line - "13" - foot digital level line synchronization signal; The white line - "14" - foot digital signal vertical field synchronization signal; VGA line shielding line - "15" - pin VGA socket housing pressure earthing. In practical engineering, often appear in the wrong wire connection, if some of the foot (such as 4, 5, 9, 15) connected with a ground wire, in the big screen does not reveal what problem; but if 10 feet off ground, there will be ground not out of the question. Some devices will not pin all the ground, although not standard, but very useful, but if you want to use a corresponding control position. 7 wire welding method three, VGA pin only welding: (as used in the wire 8 core welding) First, 1, 2 and 3 feet respectively by three wires in the wire (1 - 2 - 3 - orange, green, blue) on both sides of the color corresponding to remember; Second, 5~10 pin welding to do public together with a certain color; 8 lines in the line (here we remember "orange and white" color line), remember all the root color line two, 6, 7, 8 pins are welded together to the public on the ground; Third, 11 feet of a wire in the wire (defined here as the brown line, 11 - brown) Fourth, a 13 foot color pick in the wire line (as defined by green white, green and white - 13); Fifth, a 14 foot color pick in the wire line (as defined by green white, blue and white - 14); Sixth, 15 pin VGA socket shell crimp, (as defined by green white, brown and white, 15) No. 15 pin with 5 - 10 feet should be welded together as a wire, this is actually the 7 welding pin. If the VGA cable is coated with a special welding pin 7 if welding method is: D15 is in the ends of the 5~10 foot in public welding together; red, green and blue shield wire twisted together to the public on the ground; 1, 2, 3 feet with red, green and blue wire; 13 the yellow line; 14 white line; The outer shield pressure to the D15 plug shell, brown and black lines do not pick, but to cut, to prevent and other line series. VER 2 The method of display data line The method of display data line The current VGA mode display using pin 15. As shown in the figure: 1 red, 2 green input signal input signal, 3 Blue input signal, 4 ground or air feet, 5 feet, 6 air or ground return signal, 7 red and 8 Blue Green return signal return signal, 9 feet, 10 empty ground, 11 ground, 12 feet, 13 empty horizontal synchronizing signal 14, vertical sync signals, 15 feet. If it is a digital display, 12 feet is a serial data line, 15 foot line data clock. Connection CRT display data lines If it is connected to this end of the card can refer to the following: Nitrile nitrile nitrile nitrile nitrile nitrile nitrile Lianshan - Delta - Delta Delta Delta Delta - - - - - Lianshan Delta - Delta Delta Delta Delta - - - - - - Lianshan - Delta - Delta Delta Delta Delta - - - - - Nitrile nitrile nitrile nitrile nitrile nitrile nitrile 15 Pin foot middle triangle is VGA, The first row of the 5 needle arrangement: red, green, blue, empty, empty; The second row of the 5 needles arranged to be empty, empty, empty, empty, empty; The third row of the 5 needles arranged to be empty, empty, signal lines, signal lines, air; 1,2,3 is intuitive, the foot connecting RGB, 13,14 pin connected line field signal. Usually connected, should turn the shielding line signal line receiving joint casing, increase the anti-interference ability, or connect the screen will have interference. 15 pin type D display signal cable connector pins as follows. First, 2, 3 foot lost three color images of analog signals, they are 0.7V amplitude (peak to peak) positive signal, the input impedance is 75 ohms. Shield wires are respectively connected with the red, green and blue three signal line of the 6,7,8 pin. The 13,14 pin input separation line field synchronous signal pulse signal, they are positive or negative TTL level. Horizontal sync pulse width should be greater than 1US, the vertical sync pulse width should be greater than 560us. The signal 12,15 pin for two-way communication to achieve the display and the host of the. In the "plug and play" system, there are Serial EEPROM (EEPROM) on the display of information. In the clock under the control of the serial data line to enter the host, host, and model manufacturers understand performance of the display, automatic display system optimization. The two signal lines are not used in old-fashioned display (sometimes using fourteenth foot vertical sync pulse as the serial clock). In the high resolution display (e.g. monitor workstation), due to the video signal with wide band, and 15 pin D connector loss on the high frequency component is larger, so use BNC (Bayonet Nut Connector) connector. It adopts 5 coaxial cable plug is connected with the display. They are red, green and blue three video signal lines, the line sync signal line (white or gray), the field synchronization signal line (black). Sometimes only 3 coaxial cable plugs connected with display equipment, respectively for the video signal, the video signal of red green ten composite synchronization signal (called the green gun, blue video signal synchronization). It also uses 4 coaxial cable plug and a display device connected with the video signal, respectively, the red green blue video signal, the video signal and a composite sync signal. Personal experience: The 5 core VGA line: 1, 2, 3, 13, 14, The 9 core VGA line: 1, 2, 3, 6, 7, 8, 13, 14, the display can be bright color. But there is snow (with the original normal line will not have)
