Description
Technical field
The present invention relates to controller detection technique field, and in particular to a kind of LCD screen based on Arduino microcontrollers
Flicker Automatic adjustment method.
Background technology
Nowadays various electronic products are flooded with the life of people, need liquid crystal display mostly in these equipment
Medium as information output.More or less flicker problem is suffered from many old displays to exist, such display
Device sees that long eyes can feel fatigue, and myopia can be caused when serious.Main cause is the pupil when eyes are making viewing action
Hole can carry out size adjustment according to light intensity.When the strong light of eye gaze, pupil can diminish；Conversely, pupil can become larger.Work as people
When eye receives light intensity and acutely changes, pupil can when it is big when it is small does corresponding adjustment, since this change is usually thinner
Micro-, change of the human eye to pupil is less sensitive in addition, and common beholder may not discover.It is but exactly this trickle
Change, for a long time, it is easy to human eye is felt fatigue.In addition, during flicker is watched, eyes ciliary muscle can be suddenly
Shrink or loosen, crystalline area degree is adjusted with this, causes myopia development.
Existing liquid crystal display Flicker is mainly by panel backlit, Vcom voltage value (public electrode voltages) or face
Caused by the factors such as plate type of drive, wherein after production of liquid crystal displays manufacture, the problem of still effectively can adjusting and correct,
Major part is Vcom voltage value problem.Meanwhile Vcom voltage value problem is also the most important flicker problem of liquid crystal display.Cause
This, the flicker problem of display is always the major issue that display production firm pays close attention to, and industry also has that its is corresponding
Technical term：Flicker.
As the term suggests Flicker --- for the meaning of flicker, in display manufacturing industry, by the abnormal sudden strain of a muscle of display
Bright problem referred to as Flicker problems.Flicker problems can be divided into frequency modulation type and amplitude modulation type, that is, adjust flicker frequency and change
Kind flicker state and adjusting flicker amplitude improve flicker state.Due to most situations, human eye is can not to differentiate more than 60Hz
High frequency flicker, therefore this point is often just had been contemplated that when display product designs, the refresh rate of most of display is all
60Hz can be more than, frequency modulation type Flicker problems are just readily solved.With the continuous development of display technology, more high frequencies are shown
Show that device occurs in succession, or even the display refresh rate made at present exclusively for e-sports project is up to 144Hz, thus, frequency modulation
Type Flicker problems have been difficult to see, and the more commonly Flicker problems of amplitude modulation type.
And amplitude modulation type Flicker problems are this deviation meetings as caused by pixel voltage absolute value deviation under positive-negative polarity
Periodic brightness change is embodied over the display.This brightness change is once more than the acceptable scope of human eye, is presented on
On display is Flicker problems.And with the increase of pixel voltage absolute value deviation under two kinds of polarity, brightness change
Amplitude also accordingly increases, so how to reduce this difference just becomes the key for adjusting amplitude modulation type Flicker.It is in this regard, global
There is a different solutions in major production of liquid crystal displays manufacturer, but these solutions and non-perfect, at present to liquid crystal
Show that the Flicker of device is adjusted mainly by following several ways：
1st, human eye, potentiometer are adjusted
Liquid crystal display remains the mode adjusted to Vcom voltage value in design：By based on the special tune of potentiometer
Section rod adjusts the internal resistance of Panel (the display pannel industry term before dispatching from the factory is Panel) manually, reaches and changes Vcom electricity
The purpose of pressure value.A large amount of operators long working in production line is needed in this manner, is shown in eye-observation
After the flashing state of device, reuse corresponding regulating rod and adjust Vcom voltage value manually.But since regulating time is long (average
Every Panel spends 2-3 minute), adjusting quality it is uneven, at present except some small-sized display production firms are using this
Outside method, this technology is eliminated substantially.
2nd, human eye, PC adjust (the main application method of country facilities)
This is identical based on a kind of upper improvement project of adjusting method, substantially regulation flow process；Unlike, in liquid crystal display
When device designs, the regulative mode of Vcom voltage value is incorporated into LCD device drive chip, display and PC have been passed through
Certain mode connects, then using the upper computer software write, it is possible to adjusts Vcom voltage using computor-keyboard
Value.The benefit of this mode is, after operator skillfully grasps, can accomplish the average 15-30 seconds Flicker for completing a piece of Panel
Adjust, greatly improve speed.What is used at present in most domestic liquid crystal display manufacturing works is exactly that such flicker is adjusted
Section mode.But shortcoming is also it will be apparent that the display of operator's viewing flicker for a long time, can cause eyes different journeys
The injury of degree, adds the myopic probability of operator, therefore the work is generally worked by turns by operator, but the wheel of operator
Hilllock also result in the substantial increase of human cost, reduce factory's interests.
3rd, automation equipment adjusts (external factory owner wants application method)
In order to preferably coordinate production line to work, make it possible that full-automation produces, while save human cost,
It is imperative to develop automation equipment.Foreign well-known display production firm's Samsung and LG are in industry-leading in this field,
CA-210 (Konica Minolta color analysis instrument) has been used to measure Flicker in the automatic factory of Samsung and LG, and
Automatic adjustment to display Flicker is completed by PC (PC) program.But CA-210 prices are high, it is clear that in work
It is a large amount of using also there are many problems in factory.What is also merited attention is some color analysis instruments of the CA-210 as specialty, main
Wanting purposes, the effect of these measurements is all transcendent, is used merely to examine for information such as measurement aberration, colour gamut, brightness and contrasts
Survey flicker, which seems, wastes one's talent on a petty job.Although but CA-210 equipment is expensive, due to there is no more preferable solution temporarily at present,
Most of advanced display production firm still adheres to adjusting Flicker using CA-210.
Above LCD screen adjusting method has that of high cost, labor intensive is more, scheme many shortcomings such as time-consuming.This
Outside, due to various visible or invisible ray interference in factory, the interference of electromagnetic wave is photosensitive sensor itself dark current, non-
The composite factors such as linear and flicker high frequency stack up, and the usually accurate detection to Flicker is more difficult.
