Further, the car-mounted display control system further includes power supply unit, radio module, EEPROM, bus transmitting-receiving
Device, vehicle status detection unit and button.The MCU respectively with the power supply unit, the radio module, the EEPROM,
The bus transceiver, the vehicle status detection unit are connected with the button.
The CPU has 2 independent LCD controllers, respectively controller LCD0 and controller LCD1, this two controls
Device can handle different contents, realize while driving two shields and show that different contents, controller LCD 0 export
This is signally attached to automobile middle control instrument and shows that input interface, controller LCD 1 export 1+4 by 24bitRGB digital signals
Lane LVDS signals, can directly drive TFT screens, and IC is driven without increasing special screen.Due to eliminating single serial signal and more
Line（Multichannel）Between offset issue, therefore support up to 10 meters of cable length.It needs to use in the middle control instrument display unit
LVDS signals revivifications are rgb signal by deserializer chip corresponding with the serializer.
The CPU is additionally operable to receive the related data that MCU units transmit, and is then showed with the formal intuition of GUI,
GUI can be real in automobile instrument, HUD and guidance entertainment system.The CPU, which can be realized, directly drives the capacitance plate.
The MCU is for the detection to vehicle-state, the power management to whole system, the button management to whole system
With the management to radio module.The MCU is additionally operable to realize the connection of CAN bus transceiver, and by the CAN bus transceiver
Information parsing after be uploaded to CPU, and 2 groups of CAN bus transceivers is supported to input simultaneously.Power supply unit is realized to input electricity
The conversion of pressure chooses suitable single supply chip or power management chip according to the power domain of each functional module elements.
The vehicle mounted guidance amusement display unit is main display unit, and the picture of display is that vehicle mounted guidance amusement is related
, including main interface, each feature operation interface, navigation map, audio and video playing interface, vehicle-mounted setting interface etc..Vehicle mounted guidance
Amusement display unit is integrated with capacitance plate function, is directly operated on screen.
The main display automobile instrument related content of automobile middle control instrument display unit, remove traditional revolution counter, speed,
