Description
Technical field
The present invention relates to a kind of anti-vibration method of vehicle-mounted segment encode LCDs, belong to photoelectric display technical field.
Background technology
Segment encode liquid crystal display, which has, requires that master control extremely low, driver writes simple, easy fixation and assembles simple, price
Cheap, contrast is high and the advantages that low-power consumption, is widely used in household electrical appliance, medicine equipment and automobile instrument.Apply
When in household electrical appliance and medicine equipment, because working condition is mostly static state, so good display effect is generally capable of up to,
But when applying in automobile instrument, working environment it is unstable, speed it is too fast or traveling in bumpy road when, display
Screen can shake with jolting for automobile, produce shadow, influence display effect.The segment encode liquid crystal display used in automobile instrument
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, and Fig. 1 (a) is not
Working condition during energization, long axis of liquid crystal molecule is perpendicular to upper and lower base plate, and the polarization direction of upper down polaroid is parallel, viewing area
Domain printing opacity, 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, liquid crystal
Molecular long axis direction is parallel with upper and lower base plate, if Vehicle Speed is very fast during on state of, liquid crystal molecule is jolted, and is become
In keeping to the more stable long axis direction of center of gravity parallel to upper and lower base plate state, viewing area from dark-state on state of switch when, due to
Liquid crystal molecule receives obstruction, and the response time can be longer, because viewing area needs that on state of is presented, and liquid crystal molecule has little time to ring
Should, dark-state is still kept, so, shadow just now occurs on segment encode LCDs.
The content of the invention
The present invention is in view of the above-mentioned problems, propose that one kind can avoid segment encode liquid crystal display from producing the side of shadow under vibrating state
Method.
The present invention adopts the technical scheme that to solve the above problems：A kind of anti-vibration side of vehicle-mounted segment encode LCDs
Method, it is specially：
2 two kinds of step 1, Setting pattern one and pattern drive patterns, set different circuit interfaces, in different situations respectively
Lower access；
Step 2, vehicle static or when running at a low speed, segment encode LCDs normal work, access drive pattern one connects
Mouthful,
Step 3, judge whether Vehicle Speed exceedes preset value, if：
It is no, then it is continuing with drive pattern one；
It is then to start drive pattern two, when in viewing area being in dark-state, makes liquid crystal molecule at angle theta relative to infrabasal plate,
Reduce from dark-state on state of switch when response time, viewing area is lighted 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 inventive method by when car speed is very fast, being switched to another drive pattern, make liquid crystal molecule relative to
Infrabasal plate has certain pretilt angle, when switching from dark-state on state of, reduces the response time of liquid crystal molecule, is aobvious
Show that region lights within the shorter time, avoid shadow occur in high vehicle speeds.
Brief description of the drawings
The normal white mode displaying principle figure of Fig. 1 VA types；
The schematic diagram of Fig. 2 present invention.
Embodiment
Embodiment：Illustrate present embodiment with reference to Fig. 2, 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 patterns, set different circuit interfaces, in difference respectively
In the case of access；
Step 2, vehicle static or when running at a low speed, segment encode LCDs normal work, access drive pattern one connects
Mouthful, chip model:TYW-LCD-IC-01, instrument IC and liquid crystal drive show that IC is led to using I2C communication modes after electricity in instrument
Letter is shown；
Step 3, whether Vehicle Speed is judged more than 5km/h, if：
It is no, then continue to enable drive pattern one；
It is then to start drive pattern two, when in viewing area be in dark-state, makes liquid crystal molecule relative to infrabasal plate in 10~20
° angle, reduce from dark-state on state of switch when response time, viewing area is lighted within the shorter time.
Operation principle：
The anti-vibration method of the vehicle-mounted segment encode LCDs of the present invention, it is quiet in vehicle by setting two kinds of drive circuits
Only or during low speed smooth-ride, using drive pattern one, liquid crystal display can normally be shown；It is very fast in Vehicle Speed, produce
Jolt, dark-state on state of switch when, liquid crystal molecule need from being changed into vertical substrate state parallel to upper and lower base plate state, due to
Gravity hinders, and the response time of liquid crystal molecule increases, and now, after determining speed, segment encode liquid crystal display automatically switches to drive pattern
Two, under the drive pattern, long axis of liquid crystal molecule has a certain degree with infrabasal plate, can so reduce liquid crystal by parallel base
Board status to vertical substrate state switch when response time, be that liquid crystal molecule stands rapidly, viewing area is in the shorter time
On state of is inside switched to, eliminates shadow.
