Description
Technical field
The present invention relates to a kind of anti-vibration methods of vehicle-mounted segment encode liquid crystal display, belong to photoelectric display technical field.
Background technology
Segment encode liquid crystal display have to master control require extremely low, driver write it is simple, easily fix and assemble simply, price
The advantages that cheap, contrast is high and low-power consumption, is widely used in household electrical appliance, medical instrument and automobile instrument.It applies
When in household electrical appliance and medical instrument, since working condition is mostly static state, so it is generally capable of up to good display effect, but
It is unstable, the display screen meeting too fast or when traveling is in bumpy road in speed of working environment when applying in automobile instrument
As jolting for automobile is shaken, shadow is generated, display effect is influenced.The segment encode liquid crystal display used in automobile instrument is generally
The normal white mode of VA types, the displaying principle of this pattern are as shown in Figure 1.The pattern uses negative liquid crystal, when Fig. 1 (a) is no power
Working condition, for long axis of liquid crystal molecule perpendicular to upper and lower base plate, the polarization direction of upper down polaroid is parallel, display area light transmission,
When Fig. 1 (b) applies certain voltage between upper and lower base plate, liquid crystal molecule short axle tends to be parallel with direction of an electric field, long axis of liquid crystal molecule
Direction is parallel with upper and lower base plate, if Vehicle Speed is very fast when illuminated state, liquid crystal molecule is jolted, and tends to keep to weight
The more stable long axis direction of the heart is parallel to upper and lower base plate state, when display area switches from dark-state to illuminated state, due to liquid crystal molecule by
To obstruction, the response time can be longer, because display area needs that illuminated state is presented, and liquid crystal molecule has little time to respond, and still keeps dark
State, so, it just will appear shadow on segment encode liquid crystal display at this time.
Invention content
The present invention can avoid segment encode liquid crystal display from generating the side of shadow in view of the above-mentioned problems, proposition is a kind of under vibrating state
Method.
The present invention adopts the technical scheme that in order to solve the above problem：A kind of anti-vibration side of vehicle-mounted segment encode liquid crystal display
Method, specially：
2 two kinds of step 1, Setting pattern one and pattern drive modes, are respectively set different circuit interfaces, in different situations
Lower access；
Step 2, vehicle static or when running at a low speed, segment encode liquid crystal display normal work, access drive mode one connects
Mouthful,
Step 3 judges whether Vehicle Speed is more than preset value, if：
It is no, then it is continuing with drive mode one；
It is then to start drive mode two, when display area is in dark-state, keeps liquid crystal molecule at angle theta relative to lower substrate,
Reduce response time when switching from dark-state to illuminated state, display area is made to light within the shorter time.
Further, the preset value of the speed described in step 3 is 5km/h.
Further, angle, θ described in step 3 is 10~15 °.
Beneficial effects of the present invention：
The method of the present invention by when car speed is very fast, being switched to another drive mode, make liquid crystal molecule relative to
There is lower substrate certain pretilt angle to reduce the response time of liquid crystal molecule when switching from dark-state to illuminated state, make display
Region lights within the shorter time, avoids occurring shadow when the vehicle is driving at high speed.
Description of the drawings
The normal white mode displaying principle figure of Fig. 1 VA types；
Fig. 2 the principle of the present invention figures.
Specific implementation mode
Specific implementation mode：Embodiment is described with reference to Fig. 2, and the method flow diagram of present embodiment is as shown in Fig. 2, tool
Body step includes：2 two kinds of step 1, Setting pattern one and pattern drive modes, are respectively set different circuit interfaces, are not sympathizing with
It is accessed under condition；
Step 2, vehicle static or when running at a low speed, segment encode liquid crystal display normal work, access drive mode one connects
Mouthful, chip model:TYW-LCD-IC-01, instrument IC shows that IC is communicated using I2C communication modes to instrument with liquid crystal drive after the power is turned on
It is shown；
Whether step 3 judges Vehicle Speed more than 5km/h, if：
It is no, then continue to enable drive mode one；
It is then to start drive mode two, when display area is in dark-state, makes liquid crystal molecule relative to lower substrate in 10~20
° angle, reduces response time when switching from dark-state to illuminated state, display area is made to light within the shorter time.
Operation principle：
The anti-vibration method of the vehicle-mounted segment encode liquid crystal display of the present invention, it is quiet in vehicle by the way that two kinds of driving circuits are arranged
Only or when low speed smooth-ride, using drive mode one, liquid crystal display can normally be shown；It is very fast in Vehicle Speed, it generates
It jolts, when dark-state switches to illuminated state, liquid crystal molecule needs to become vertical substrate state from being parallel to upper and lower base plate state, due to weight
Mechanical resistance hinders, and the response time of liquid crystal molecule increases, at this point, after determining speed, segment encode liquid crystal display automatically switches to drive mode two,
Under the drive mode, long axis of liquid crystal molecule has a certain degree with lower substrate, can reduce liquid crystal in this way by parallel substrate shape
Response time when state switches to vertical substrate state, liquid crystal molecule is set to stand rapidly, display area is cut within the shorter time
Illuminated state is changed to, shadow is eliminated.
