Abstract
The utility model discloses an intelligent vehicle-mounted terminal LCD and LED display panel compatible circuit structure. The circuit structure is characterized by comprising a mainboard and a display drive signal socket installed on the mainboard. An LCD drive signal pin area is connected with an LCD drive unit by a data line. An LED drive signal pin area is connected with an LED drive unit by the data line. When the circuit structure is in use, if an LCD drive signal receiving receptacle is the one that is connected with the display drive signal receptacle by the data line, then the LCD drive signal pin on the LCD drive signal receiving receptacle is correspondingly connected with the LCD drive signal pin area; and if an LED drive signal receiving receptacle is the one that is connected with the display drive signal receptacle by the data line, then the LED drive signal pin of the LED drive signal receiving receptacle is correspondingly connected with the LED drive signal pin area. By means of the composite configuration of the structure and interfaces, the circuit structure realizes both the LCD display and the LED display on one mainboard so that products can be flexibly configured based on the two display requirements.
Description
Technical field
The utility model relates to the circuit structure of a kind of intelligent vehicle mounted terminal LCD and LED display board compatibility.
Background technology
What existing intelligent vehicle mounted terminal generally adopted is that LED shows.Development along with integrated circuit technique, the function that intelligent vehicle mounted terminal can be finished is more and more, need the quantity of information of demonstration also increasing accordingly, when the LED demonstration can not be satisfied the application of the higher intelligent vehicle mounted terminal of degree of intelligence, can adopt to show that the bigger LCD of quantity of information shows as display device.Therefore as the product that updates, intelligent vehicle mounted terminal will generally adopt LCD to show.
But the market demand determines the product pattern, the intelligent vehicle mounted terminal of LED demonstration at present also has the very big market demand, therefore a tame intelligent vehicle mounted terminal production firm is when the research and development product, to develop the mainboard of two kinds of models simultaneously to adapt to the application that LCD shows or LED shows, when LED display terminal and LCD display terminal are changed mutually, just must change whole mainboard, even change entire equipment.This just makes the waste that the production cost is higher and cause resource.Therefore the circuit structure of a kind of intelligent vehicle mounted terminal LCD and LED display board compatibility is badly in need of being developed to address the above problem.
Summary of the invention
The utility model is at the proposition of above problem, and develops the circuit structure of a kind of intelligent vehicle mounted terminal LCD and LED display board compatibility.The technological means that the utility model adopts is as follows:
The circuit structure of a kind of intelligent vehicle mounted terminal LCD and LED display board compatibility is characterized in that comprising: mainboard and the display drive signals socket that is arranged on the mainboard; Described display drive signals socket drives the signal pins district by LCD and LED driving signal pins district constitutes; Described LCD drives the signal pins district and connects with the LCD driver element by data line, and described LED drives the signal pins district and connects with the LED driver element by data line; Described display drive signals socket is complementary with the LED driving signal receiver socket that the LCD on the LCD display board drives on signal receiver socket and the LED display board respectively;
During use, drive the signal receiver socket by data line with the LCD that is that the display drive signals socket is connected, then LCD drives LCD on the signal receiver socket and drives the signal pins correspondence and be connected LCD and drive in the signal pins district; Drive the signal receiver socket by data line with the LED that is that the display drive signals socket is connected, then LED drives LED on the signal receiver socket and drives the signal pins correspondence and be connected LED and drive in the signal pins district.Described display drive signals socket is the 50PIN signal plug.40PIN in the described display drive signals socket is that LCD drives signal pins, and 10PIN is that LED drives signal pins.
Owing to adopted technique scheme, the circuit structure of the intelligent vehicle mounted terminal LCD that the utility model provides and LED display board compatibility, compound setting by structure and interface, realized that a mainboard namely is suitable for LCD and shows that being suitable for LED again shows, makes product can carry out flexible configuration to two kinds of display requirements.In addition, because it is simple in structure, not only be convenient to produce, and with low costly be suitable for extensive popularization.
