Abstract
The invention discloses a liquid crystal instrument which comprises a main control chip, a graphics processing module and a display screen, wherein the main control chip is connected with the display screen via the graphics processing module, and the main control chip is also connected with an electronic control unit, a digital quantity input/output interface circuit and a navigator. The liquid crystal instrument can display more vehicle condition information and navigation information.
Description
Technical field
The present invention relates to a kind of liquid crystal instrument, particularly a kind of full graphics liquid crystal instrument for automobile.
Background technology
Existing auto meter is divided three classes: 1) traditional pointer stepping motor gauge panel cooperates the black-and-white crystal screen, and wherein pointer shows information such as the speed of a motor vehicle, engine speed, oil mass, engine temperature, and the black-and-white crystal screen shows information such as mileage, oil consumption; 2) pointer stepping motor gauge panel cooperate large-size color LCD screen wherein pointer show information such as the speed of a motor vehicle, engine speed, oil mass, engine temperature, color LCD screen shows information such as reverse image, vehicle condition; 3) full liquid crystal instrument goes out pointer with the liquid crystal display image virtual and shows information such as the speed of a motor vehicle, engine speed, and other show information such as vehicle condition, reverse image with the pictograph form.Prior art can only the traditional information of display automobile; Such as the speed of a motor vehicle, engine speed etc.; Can not represent more picture-character information to the car owner; Even the full graphics liquid crystal instrument, also just simulation shows information such as speed of a motor vehicle pointer, can not show the for example complex information of navigation map, automobile specification sheets and so on.The major cause that prior art produces these problems is that graphical interfaces is imperfect, do not have mutual communication with automobile navigation instrument, does not possess communication interface.
Summary of the invention
Goal of the invention: the problem and shortage to above-mentioned prior art exists, the purpose of this invention is to provide a kind of liquid crystal instrument, can show more vehicle condition information and navigation information.
Technical scheme: for realizing the foregoing invention purpose; The technical scheme that the present invention adopts is a kind of liquid crystal instrument; Comprise main control chip, pattern process module and read-out; Said main control chip connects read-out through pattern process module, and said main control chip also connects electronic control unit, digital quantity input/output interface circuit and navigating instrument respectively.
Said read-out can be LCDs.
Beneficial effect: various comprehensive information of vehicles (like back glass port heating-up temperature, hazard warning lamp information etc.) can centralized displaying on gauge panel, display interface is magnificent, comes into plain view, and is more clear and intuitive than traditional instrument.Changeing instruction on the gauge panel about show navigator, make chaufeur can rotate eyes and see the console navigating instrument, just can realize navigation function, improved traveling security.Adopt pointer-type and the digital graphical interfaces that combines, the main separation of can buying car in installments is selected the interface, satisfies the customer requirement of different esthetic requirements.
Description of drawings
Fig. 1 is the functional block diagram of liquid crystal instrument of the present invention;
Fig. 2 is the show state figure of liquid crystal instrument of the present invention.
The specific embodiment
Below in conjunction with accompanying drawing and specific embodiment; Further illustrate the present invention; Should understand these embodiment only be used to the present invention is described and be not used in the restriction scope of the present invention; After having read the present invention, those skilled in the art all fall within the application's accompanying claims institute restricted portion to the modification of the various equivalent form of values of the present invention.
As shown in Figure 1, the driving circuit (pattern process module) of 7 inches TFT color line screens of design comprises the SAPPHIRE chip of a printer Fujisu, its inner more integrated automobiles picture library commonly used, and link to each other with main control chip LPC11C14 chip with the IO mouth.The LPC11C14 chip is as the external circuit control chip; Connect digital quantity input/output interface circuit, CAN communication interface circuit TJA1040T and RS485 communication module; CAN communication interface circuit TJA1040T and automobile ECU (Electronic Control Unit wherein; Electronic control unit) communicates; RS485 communication module and navigating instrument communicate, and can the instruction of various comprehensive information of vehicles (like back glass port heating-up temperature, hazard warning lamp information etc.) and navigating instrument (about change etc.) be presented on 7 inches TFT color line screens.
Fig. 2 shows the show state of 7 inches TFT color line screens; It is thus clear that current read-out has shown time on date, accumulated distance, subtotal mileage, engine speed, engine temperature, oil meter indication, tire pressure, gear information, water level information, vehicle current driving state and navigation information etc., and is very comprehensive.
Claims (2)
1. a liquid crystal instrument comprises main control chip, pattern process module and read-out, and said main control chip connects read-out through pattern process module, and said main control chip also connects electronic control unit, digital quantity input/output interface circuit and navigating instrument respectively.
2. according to the said liquid crystal instrument of claim 1, it is characterized in that: said read-out is a LCDs.
