Below with reference to the accompanying drawings the invention will be further described with optional embodiment.
As shown in Figure 1, the embodiment of the present invention discloses a kind of design method of the overcurrent protection value of display panel, including
Step:
S11: it is not turned on the overcurrent protection module of display panel；
S12: by signal line short circuit at least two in display panel, the corresponding current value of short dot and display are measured
The temperature value of panel is calculated when the temperature value of the display panel meets preset condition according to the corresponding current value of short dot
Minimum current value；
S13: overcurrent protection value is set by the minimum current value.
In the present solution, we are not turned on overcurrent protection at the beginning, and will at least more than two signal line short circuits, measure
The temperature value of short dot corresponding current value and display panel, when the temperature value of display panel meets our preset condition,
Minimum current value is calculated according to the corresponding current value of short dot；The overcurrent condition of experiment simulation short circuit, and according to display panel
Temperature conditions is assumed to be the phenomenon that polaroid is burnt with preset temperature value, therefrom obtains minimum current value conduct when burning
Overcurrent protection value.For the source empirical value of overcurrent protection value is come the scheme that sets, since polaroid etc. is external
Burning for device is that we macroscopically can see, and individual part and burning for cabling may not influence display panel
Normal display, if the current value of individual part and cabling burnt is used to may result in overcurrent as overcurrent protection value
The setting of protection value is too small, may in actual use, because external slight influence will such as situations such as voltage instability
There is the phenomenon that display panel error cut-off machine, influences user experience instead；And we will at least more than two signal line short circuit, amount
The temperature value of short dot corresponding current value and display panel is surveyed, and is showed what preset temperature value hypothesis external devices were burnt
As, minimum current value at this time is more suitable as overcurrent protection value, not only effectively realize overcurrent protection, but also can be with
It avoids the setting of too small overcurrent protection value from leading to the phenomenon that display panel error cut-off machine occur because of external slight influence, improves
User experience.
In one embodiment, the display panel temperature meets preset condition are as follows: when being greater than preset temperature threshold, according to short
The corresponding current value of waypoint calculates minimum current value.In the present solution, preset condition mainly within the temperature range of a regulation,
The preset threshold of namely one temperature only meets condition, that is, is greater than preset temperature threshold, we just can be according to short
The corresponding current value of waypoint calculates minimum current value, this ensure that the reliability of the minimum circuit value obtained, in order to avoid because its
The variation of some temperature generated caused by his problem influences experiment value.
In addition before carrying out short circuit, we can recorde the size of the current value of signal line and the temperature of display panel
Value, as reference control value, the minimum current value for preventing the generation of other situations from us being caused to obtain is less than normal.
In one embodiment, the preset temperature threshold is 40 degree to 60 degree.In the present solution, preferable temperature is 45 degree, GOA
Temperature value when product is the phenomenon that client has occurred polaroid warpage and burns is 45 degree or so, and this programme is mainly also needle
To the design that the optical diaphragms such as polaroid are made, once it can compare on a display screen because phenomenon is burnt in polaroid appearance
Obviously, the complaint of client will certainly be caused, in order to solve the problems, such as customer complaint, temperature when we are burnt using polaroid is as threshold value temperature
Degree.Certainly, those skilled in the art can also select other temperature thresholds as the case may be.
In one embodiment, after the short circuit by more than two signal line, the corresponding current value of real-time monitoring short dot
With the temperature value of display panel, after one section of ageing time, when detect meet be greater than preset temperature condition when, according to short dot
Corresponding current value calculates minimum current value.In the present solution, it is contemplated that the display situation of entire display panel, so OCP
Value cannot be arranged excessive, and what cannot also be arranged is too small.If what is be arranged is excessive, can not play a protective role；If set
The case where that sets is too small, and panel often will appear shutdown can also bring certain influence to client, by one section of ageing time
It afterwards to the current value of display panel and temperature value real-time monitoring, compares and analyzes, in addition will certainly cause temperature value when aging
With the variation of current value, show that data are more accurate in variation.
In addition, measuring or the position of the temperature value of monitoring can generally can be bigger in short dot, the electric current of short dot
Or temperature is relatively higher elsewhere, then value when obtained numerical value can be burnt closer to polaroid.
In one embodiment, the signal line include at least four, it is described will be at least two in display panel
In the step of signal line short circuit, after at least four signal line two-by-two short circuit, then the corresponding current value of short dot is measured.This
In scheme, at least four signal wires carry out short circuit two-by-two, then obtained minimum current value is comparable, it is not in last
Obtained minimum current value is too small, so that being unable to satisfy actual demand.And it is short-circuit two-by-two, short dot is more, can pass through
More data compare screening, keep experimental result more convincing and reliability.
Certainly, the signal line can have more, described by signal line short circuit at least two in display panel
The step of in, after all signal line simultaneously short circuit, then measure the corresponding current value of short dot.More signal line are short simultaneously
The electric current on road, corresponding short dot is larger, is not in that the minimum current value that finally obtains is too small, so that being unable to satisfy reality
Demand.It should be noted that more than two signals are at least two signal line in GOA circuit, transmission is GOA news
Number；In addition, the signal line of the different signals of two transmission is mainly carried out short circuit when short circuit.
It in one embodiment, further include testing after described the step of setting overcurrent protection value for the minimum current value
Demonstrate,prove step:
Using the minimum current value as the overcurrent protection value in overcurrent protection module, the overcurrent of display panel is opened
Protective module；
At least two signal line are artificially short-circuit；
The temperature value for measuring the short dot corresponding current value and display panel of two signals, verifies the overcurrent protection
Whether value meets requirements for overload current protection.
In the present solution, minimum current value is set as current protection value, opens display panel after obtaining minimum current value
Overcurrent protection module；At least two signal line are carried out to artificial short circuit；Generally pass through specific board for two signals
Line carries out welding manufacture short circuit, and the temperature value and record of short dot corresponding current value and display panel are measured after short circuit, is completed
Verifying.According to verifying situation, whether desirable the overcurrent protection value can be preferably detected.
In one embodiment, the quantity of signal line short-circuit in the verification step is less than near in the step S12
Few more than two signal line short circuits, the step of to calculate minimum current value in short-circuit signal line quantity.In the present solution,
In verification step, the quantity of signal line short circuit is less than the quantity of the signal line of short circuit when calculating minimum current value by we, is such as existed
It calculates in step, sets whole short circuits for all signal line, and in verification step, set short two-by-two for all signal line
Road, in this way, the quantity of the signal line of verification step is less than the signal of the needs short circuit in the step of obtaining minimum current value
Line should relatively be obtained when obtaining minimum current value by the data of multiple signal line, it was therefore concluded that after, if only verified,
It causes more to damage in order to prevent, causes unnecessary waste, select less signal line short circuit, in addition found out most in experiment
Low current value, short-circuit signal line is more, and electric current in circuit can be made bigger, is more conducive to find out minimum current value in this way, and tests
When card, because being set as overcurrent protection value with minimum current value, therefore select the signal line of short circuit fewer than upper, such circuit
In circuit it is smaller, verify it is more accurate；In addition, in carrying out verification step, before by corresponding signal line short circuit, I
Can recorde signal line current value size and display panel temperature value, as the reality in reference value and verification step
Data in the step of testing value, even calculating minimum current value compare.

Current value；
S23: overcurrent protection value is set by the minimum current value；
S24: using the minimum current value as the overcurrent protection value in overcurrent protection module, the mistake of display panel is opened
Overcurrent protection module；
S25: at least two signal line are artificially short-circuit；
S26: the corresponding current value of short dot and panel temperature of two signals are measured, verifying the overcurrent protection value is
It is no to meet requirements for overload current protection.
In the present solution, main purpose is that polaroid is burnt in order to prevent, and manufactures the phenomenon that polaroid is burnt by experiment
Obtain overcurrent protection value, burning for polaroid is that we macroscopically can see, and polaroid, which is burnt, is also due to panel
Caused by middle all parts and cabling are burnt.Individual part and cabling burn the normal display that may not influence panel；
If using the current value of component and cabling out of the ordinary burnt as current protection value, it is frequent may just to will appear panel in client
The phenomenon that shutdown；In experiment, we are not turned on overcurrent protection at the beginning, and will at least more than two signal line short circuits, it is real
The phenomenon that manufacture polaroid is burnt is tested, the corresponding current value of short dot and panel temperature are measured, when the panel temperature meets me
