Description
Technical field
The utility model relates to field of display technology more particularly to a kind of anti-interference liquid crystal display die sets.
Background technique
Liquid crystal display die set (LCM, LCD Module) is usually made of driver module and liquid crystal display (LCD),
Driver module is usually made of PCBA, driving IC, soft copy.The working principle of LCM are as follows: LCM display module is electronic light
Power conversion device, the power supply and control signal of the output of PCB interface access terminal mainboard, is finally transferred to by PCB or FPC
IC makes IC work export corresponding drive waveforms and drives to LCD so that control and driving LCD show that LCD liquid crystal does not shine
Waveform changes the voltage difference for being added in liquid crystal molecule both sides with the variation of waveform, and the arrangement twisted state of liquid crystal molecule is also therewith
Variation, the throughput of the height control light of voltage, realizes light and shade variation, is allowed to show that required datagraphic, LCM are realized
Conversion from electric signal to light image.
Liquid crystal display die set needs the standard by the projects such as electrical fast transient (eft) (EFT) and static discharge (ESD)
Test.EFT experimental principle are as follows: EFT signal pulse is a kind of bursty interference, and crest voltage may be up to 4kV, rising edge 5ns, tool
Have a features such as burst, high pressure, wideband, EFT experiment be it is a kind of be coupled to power circuit, control route, on signal line by being permitted
How soon the impulse train test of fast ringing pulse composition, electric fast-pulse group is made of the successive pulse groups for being divided into 300ms, often
One train of pulse continues 15ms, is made of several non-polar single pulse waveforms, the rising edge 5ns of single pulse, when continuing
Between 50ns, repetition rate 2.5KHz (to 4KV test grade).
Existing liquid crystal display die set cannot be tested by 4 grades of EFT, and display is abnormal, the place that should not be shown occur
There is the phenomenon that display and quick disappearance, find after analyzing the reason of phenomenon: the phenomenon is by signal wire by bursty interference
Cause.
To solve the above problems, existing solution is general are as follows: liquid crystal display die set is grounded mode, PCB using iron frame
Cabling increases earth-return design, increases the circuit IT0 on LCD and shields interference source, reduces alternatively, increasing filter circuit in client
Interference source come attempt improve immunity to interference.
However, above-mentioned solution has the drawback that Anti-interference Design is applied in part, interference source can be from LCD's
Other approach such as the ITO route in signal pins, driving IC, LCD step (non-display area), which seal in, makes mould group EMC test failure,
I other words local Anti-interference Design cannot play anti-interference protective effect to entire LCD screen, cause liquid crystal display die set one
It is not normally functioning in a little electromagnetic interference environments, phenomena such as display messy code occurs.
