Emitting Diodes, light emitting diode with quantum dots) or flexible displays etc..
As shown in Figure 1, the method provided in this embodiment for improving screen flicker, comprising:
Step S101, whether the display frequency conversion function for detecting display is opened.
In a particular application, whether the display frequency conversion function of display is opened, and by corresponding software program or can be
System setting program is controlled, and user can carry out human-computer interaction with display by any feasible man-machine interaction mode, with
Open or close display frequency conversion function.
In one embodiment, include: before step S101
Display frequency conversion function open command is obtained, the display frequency conversion function of the display is opened.
In one embodiment, before step S101 further include:
Initialize the processor of the display；
Initialize the communication data between the I/O interface and peripheral components of the processor.
In a particular application, processor is the calculator in display for being controlled the working condition of display
Part, for realizing that the method for improving screen flicker needs elder generation before entering step S101 when running a computer program
Processor is initialized, processor is made to enter working condition.
In a particular application, peripheral components may include power supply device, display screen, memory etc., realize the base of display
The indispensable necessary device of this display function, the number amount and type of peripheral components are related to the type of display, Ke Yigen
It is select and set according to actual needs.
Step S102, when the display frequency conversion function is opened, whether the display signal for detecting the display access is propped up
Hold display frequency conversion function.
In a particular application, display frequency conversion function is realized, the frequency of the display signal of display access should also be as being not
Disconnected variation, without being fixed and invariable.Therefore, whether can constantly be changed by the frequency of detection display signal, to judge
Whether display signal supports display frequency conversion function.
In one embodiment, after step S101, further includes:
When the display frequency conversion function is not opened, stop executing subsequent operation.
In a particular application, when showing that frequency conversion function is not opened, the problem of display is not in screen flicker, thus
It needs not continue to execute subsequent step.
Step S103, when the display signal supports display frequency conversion function, the frequency variation of the display signal is detected
Whether rate is greater than default change rate.
In a particular application, it if the frequency of display signal constantly changes, but if change rate is lower, not will lead to
Whether screen flicker, being greater than therefore, it is necessary to detecting the frequency change rate of display signal will lead to the default change rate of screen flicker.
Default change rate can be configured according to actual needs, specifically related to the performance parameter of display.
In one embodiment, after step S102, further includes:
When the display signal does not support display frequency conversion function, stop executing subsequent operation.
In a particular application, when showing that signal does not support display frequency conversion function, display is not in screen flicker
Problem, thus need not continue to execute subsequent step.
Step S104, when the frequency change rate is greater than default change rate, the current frequency of the display signal is determined
Affiliated frequency range.
In a particular application, when showing the frequency variation of signal, the intrinsic brilliance and Benchmark brightness that can make display are (i.e.
Display is when accessing the display signal of the changeless reference frequency of frequency, the normal brightness that should show) there is deviation.Display
When the frequency of signal is higher than reference frequency, the intrinsic brilliance of display can be made 3cd/m higher than Benchmark brightness2Left and right；Display letter
Number frequency be higher than reference frequency when, the intrinsic brilliance of display can be made 3cd/m lower than Benchmark brightness2Left and right.
In a particular application, display access different frequency display signal when intrinsic brilliance and Benchmark brightness between
Luminance difference will be different.Relationship between the intrinsic brilliance of usual display and the frequency for showing signal is not stringent line
Sexual intercourse, but the progressive relationship of ladder, when the frequency for showing signal changes in a certain frequency range, the reality of display
Brightness is identical, and the intrinsic brilliance of the corresponding display of different frequency ranges is different.It is thus necessary to determine that display signal is current
Frequency range belonging to frequency, the luminance difference between intrinsic brilliance and Benchmark brightness in order to determine display, thus to aobvious
Show that the brightness of device is adjusted.
In one embodiment, before step S104, comprising:
Detect the frequency range of the display signal；
Obtain the brightness when display signal of the display access different frequency；

It, will be described when the lower limit value of the frequency range belonging to the current frequency is greater than the upper limit value of reference frequency range
The brightness regulation of display is the present intensity of the display and the difference of the luminance difference.
Step S106, whether the frequency change rate for returning to the detection display signal is greater than default change rate.
In a particular application, after having adjusted the present intensity of display, i.e. return step S103, detection display again
Whether the frequency change rate of signal, which is greater than, to loop back and forth like this, until display the default change rate for causing screen flicker
Stop access display signal, no longer shows picture.
The present embodiment is opened by the display frequency conversion function in display, the display signal of display access supports display to become
When the frequency change rate of frequency function and display signal is greater than default change rate, frequency belonging to the current frequency of display signal is determined
Range, then the frequency range according to belonging to the current frequency of display signal, adjusts the present intensity of display, can effectively change
Kind display is when screen refresh frequency is higher, the screen flicker problem that display picture occurs, so as to improve the use feeling of user
By and vision health.
