Vehicle real-time traffic information acquisition module 2 is used for gathering automobile real-time traffic information and sending this information to MCU controller 1.Wherein, automobile real-time traffic information is status information during automobilism, it includes fault message, mileage information, oil temperature information, oil pressure information, water temperature information, tire pressure etc., difference according to automobile real-time traffic information, vehicle real-time traffic information acquisition module 2 can use different sensors to realize, such as oil temperature information and water temperature information can be gathered by temperature sensor, and oil pressure information can be gathered by pressure transducer.
MCU controller 1 is provided with configuration software, and configuration software for being converted into driving signal and being sent by this driving signal to OLED driving module 4 by the automobile real-time traffic information of reception.
OLED drives module 4 to drive OLED Curved screen display vehicle real-time traffic information picture according to the driving signal received.OLED drives module 4 to include row cutting module, row driving module and some constant-current sources, and row cutting module includes that several horizontal drive circuits, row drive module to include several column drive circuits, and each row electrode of column drive circuit is respectively connected with a constant-current source.
Fig. 2 is the column drive circuit that OLED drives module 4 drive circuit, as in figure 2 it is shown, column drive circuit includes shift register U1, audion QA, audion QB, audion QC, audion QD, metal-oxide-semiconductor QE, resistance R1, resistance R2, resistance R3, resistance R4, resistance R5, resistance R6.Audion QA, audion QB, audion QC are PNP type triode, and audion QD is NPN type triode, and metal-oxide-semiconductor QE is N-channel MOS pipe.Shift register U1 uses 74HC595, its input is connected with MCU controller 1, its outfan is connected with the grid of metal-oxide-semiconductor QE, one end of the source electrode of metal-oxide-semiconductor QE and resistance R4, one end of resistance R5, one end of resistance R6 are connected, another termination power module of resistance R4, the other end of resistance R5 is connected with the base stage of audion QC, and the other end of resistance R6 is connected with the base stage of audion QD.The colelctor electrode of audion QC is connected with the colelctor electrode of audion QD, the common port of the colelctor electrode of the colelctor electrode of audion QC and audion QD drives the outfan of signal as row, the grounded emitter of audion QD, the emitter stage of audion QC is connected with the colelctor electrode of audion QB, and the base stage of audion QB is connected with the base stage of audion QA.The operation principle of column drive circuit is described below.
Driving current ratio row electrode required on row electrode is little, because row electrode is to gate line by line, the row electrode of gating corresponding unique row electrode when pixel is lit, when certain a line is strobed, video data thereon is sent to row addressed module immediately, then shows on OLED camber display screen arranges accordingly.The push-pull driver circuit as in figure 2 it is shown, audion QC and audion QD partners, when shift register U1 is output as high level, metal-oxide-semiconductor QE turns on, and metal-oxide-semiconductor QE is output as low level, and resistance R5, resistance R6 select suitable resistance value, audion QC saturation conduction, audion QD reversely ends.When the column data signal of shift register U1 output is low level, metal-oxide-semiconductor QE ends, and metal-oxide-semiconductor QE exports high level, high level makes audion QD saturation conduction, audion QC reversely ends, and the output electric current of the constant-current source being connected with row electrode is cut off, row electrode output low level.Audion QC, audion QD is that two complementary audions are as push-pull drive, specifically, resistance R5 is identical with the resistance of resistance R6, the effect of resistance R5 and resistance R6 is to audion QC, audion QD carries out current limliting, the electric current being avoided by is excessive and burns out audion, audion QC and audion QD is in a conducting all the time, the state of one cut-off, the each waveform being responsible for positive and negative half period of audion QC and audion QD amplifies task, during circuit work, two symmetrical power switch pipe each only one of which conductings, so the little efficiency of conduction loss is high, recommend output and both can fill electric current to load, can also be from load extraction electric current.When metal-oxide-semiconductor QE is output as low level, suitable resistance value is selected to make audion QC saturation conduction, audion QD reversely end；When metal-oxide-semiconductor QE is output as high level when, suitable resistance value is selected to make audion QD saturation conduction, audion QC reversely end.
Fig. 3 is the horizontal drive circuit that OLED drives module 4, as in figure 2 it is shown, it includes shift register U2, metal-oxide-semiconductor QF, resistance R7.Metal-oxide-semiconductor QF uses N-channel MOS pipe.Shift register U2 uses double four bit shift register CD4015 sealing in and going out, the input of shift register U2 is connected with MCU controller 1, its outfan is connected with the grid of metal-oxide-semiconductor QF, the grounded drain of metal-oxide-semiconductor QF, the source electrode of metal-oxide-semiconductor QF is connected with one end of resistance R7, the other end of resistance R7 is connected with power module, and the common port of the source electrode of metal-oxide-semiconductor QF and resistance R7 is as the horizontal-drive signal outfan of horizontal drive circuit.The operation principle of description line drive circuit below.
The major function of horizontal drive circuit is to be replaced base line, the PM-OLED Curved screen that the present embodiment uses is matrix panel, it is formed according to the arrangement of ranks order by the OLED of single pixel, it is connected in parallel with between anode and the anode of a line, equally, also it is connected in parallel with between negative electrode and the negative electrode of a line.MCU controller 1 sends row scanning initial signal, shift signal, horizontal drive circuit receives these signals, when shift register U2 is output as high level, the metal-oxide-semiconductor QF conducting of this row, it is low level that horizontal-drive signal outfan exports the signal of row electrode, and this row is switched on, other do not receive the row electrode of gating signal, owing to its corresponding metal-oxide-semiconductor is in cut-off state, being added in voltage thereon is high level VCC so that it is be suppressed cut-off under the effect of backward voltage.Base line needs 10～20mA electric currents, and Non-scanning mode row needs the high level blanking voltage of 10～15V.
As can be seen from the above embodiments, this utility model embodiment this utility model uses OLED Curved screen as the display module of vehicle surface composition instrument, owing to OLED camber display screen good springiness and shock resistance are strong, therefore, it is possible to strengthen the ruggedness of vehicle surface composition instrument, OLED curved face display panel more meets ergonomic designs simultaneously, therefore, it is possible to alleviate visual fatigue.It addition, the embedded configuration program of this utility model embodiment is more attractive in appearance, natural by the display effect of instrument, and can be shown in a graphical form by the automobile real-time traffic information that collect, result more accurately image, response speed are faster.
It is to be appreciated that the embodiment of foregoing description is a part of embodiment of the present utility model rather than whole embodiment, it is not to restriction of the present utility model.Based on embodiment of the present utility model, the every other embodiment that those of ordinary skill in the art are obtained under not paying creative work premise, broadly fall into protection domain of the present utility model.
