Display interface
1, R red
2, G green
3, B blue
When the three wires are broken, it will cause color deficiency.
5. There is at least one GND, and it will not jump.
13. HS line synchronous pulse whose frequency determines resolution
14. VS field synchronous pulse whose frequency determines refresh rate
When the two lines are disconnected, there is no signal input.
6, 7, 8, RGB shielded ground wire, anti-interference. The three wires enclose the 1, 2 and 3 wires and grounding them.
9. The empty foot or + 5V foot, which is powered by graphics card output + 5V, can supply power for 24 chips.
4, 10, 11 GND on-line detection.
12. SDA Serial Data, Complete Communication Bus
15. SCL Serial Clock and Bipod Brush Program
24 chips: memory chips.
Point screen
Intermediate grounding wire is anti-jamming
The white spot on the screen line is the first stitch.
Three elements:
Power supply: over 17 inches 5V power supply 15 inches 3.3V/5V
Screen Line: Red Line Power Supply, Black Line GND. Put it on the board.
According to the screen line, the steps are as follows:
1) To be able to connect to the screen line;
2) Measure whether the red line is grounded or not, and it is not grounded correctly.
3) Measure whether the black wire is grounded and the grounding is correct.
4) Measure the resistance of blue and white lines. The resistance of each group is about 100 Euros.
LVDS screen line:
DF19 needle insertion, single support DF14 needle insertion without support
FLX film insertion, 51146 pin insertion without support
Resolution: Completed by a programmer.

DO8 (double 8) D8 (single 8)
SI8 (single 8) S8 (double 8)
Note: When brushing the screen, the power can't be cut off. Whatever brand the board is, the program will be brushed and the chip will be burned if the operation is improper.

General Programming Method:
Model of board + model of screen + classification of screen and number of signal bits + supply voltage of screen + number of keys + audio + menu language
Example: 2013B_LTM150XH_T01_D6T_3.3V_5J_A_EN
2013B represents the general board of 2013B.
LTM150XH_T01 is the model of screen.
D6T represents a single 6-bit TTL screen.
3.3V fingerprint is powered by 3.3V.
5J 5KEY represents five keys.
A stands for audio NA for no audio;
EN stands for English menu.
Interface type and signal multiplier labeling of screen:
D6T: Single 6-bit TTL S8L: Double 8-bit LVDS
LD6L: Single 6-bit LVDS LS6T: Double 6-bit TTL
SI8L: Single 8-bit LVDS D08L: Double 8-bit LVDS
SIRSDS: Single RSOS DOTCON: Double TCON
SI**S: single **S
Note: SI is the abbreviation of SINGLE in English, which stands for singular number.
DO is the abbreviation of DOUBLE in English, representing double numbers.
D, LD, SI represent units, S, LS, DO represent double digits;
Point screen steps:
According to the screen model, size, screen line interface, preliminary estimation of the screen signal, type, signal multiples, power supply voltage, you can also check the PDF specifications according to the screen model, confirm the relevant information, if there is no PDF specifications of the prototype number, you can check the information of the screen similar to his model.
Choose the appropriate screen line according to the type of screen line interface. Many of the screen line interfaces of LVDS are similar, so pay attention not to choose the wrong ones.
According to signal type and signal multiplier, RTD2023L scheme supports all LVDS screens, TTL screens and the most complete program. GM2621 also supports LVDS, but brushing is troublesome. The scheme of RTD2013B or RTD2523 supports all TTL screens, and the program is complete. The latest RTD2033 board supports all TTL and LVDS screens. The price is lower than that of 2013, but the current program is not enough.
Connect the parallel port of the programmer with the USB cable, and then select the corresponding mode of the programmer according to the MCU model of the board used:
Model 1: RTD2120, MTV512, MST and TSUM series;
Model 2: SM5964, SM59264, GM2621, GM5621;
Mode 3: NT68F63, NT68F633, NT68625 series.
The power supply voltage selected by the route is inserted with signal line, high voltage board, screen line, pay attention to the screen line not to insert reverse, one foot alignment; connect the driver board with VGA line to the VGA port of the programmer, and then electrify the driver board;
Open the software of the corresponding mode and select the corresponding folder according to the manufacturer's logo on the drive board.
