An embodiment of the present invention provides a kind of method that improvement display screen is shown and electronic devices, can improve the electronics
The display effect and picture quality of the display screen of device.It is described in detail separately below.
Scheme in implementing in order to better understand the present invention, the embodiment of the present invention disclose a kind of system tray of display screen
Structure, in the embodiment of the present invention, the display screen can be thin film field effect transistor-liquid crystal display (Thin Film
Transistor-Liquid Crystal Display, TFT-LCD) display screen, or other flat display apparatus.
By taking the display screen of the TFT-LCD in Fig. 1 as an example, as shown in Figure 1, in display screen including multiple TFT (TFT1 as shown in Figure 1,
TFT2, TFT3 etc.) and corresponding multiple liquid crystal pixels (lc1, lc2, lc3 etc. as shown in Figure 1), the source electrode of each TFT
It is connected to data signal line (Data1, Data2, Data3 in such as Fig. 1), the grid of each TFT is connected to controlling grid scan line
(Gate1, Gate2, Gate3 in such as Fig. 1), wherein data signal line can be connected to source drive module, be driven by source electrode
Dynamic model block drives data signal line.One end of drain electrode one liquid crystal pixel of connection of one TFT, the liquid crystal pixel
The other end connects reference voltage Vcom, for example, one end of the drain electrode connection liquid crystal pixel lc1 of TFT1, liquid crystal pixel lc1's is another
End connection reference voltage Vcom.Reference voltage Vcom is a shared identical common electrical of liquid crystal pixel all in display screen
Pressure needs to use common voltage to ensure the consistency of display screen display effect.
Frame frequency (frame rate) refers to display screen projection each second or the frame of display or the quantity of image.For example, by using frame
Frequency is the display screen of 60Hz, and display screen only shows a frame picture in 1/60 second, uses frame frequency for the display screen of 40Hz, display screen
A frame picture is only shown in 1/40 second.As it can be seen that frame frequency is higher, the picture frame number that display screen can be shown within the same time is got over
It is more, show that the image of moving object will be more smooth.
During the use of liquid crystal display panel, since the polarity switching of reference voltage (Vcom, also known as common voltage) can produce
The scintillation of the flat striped of unboiled water, referred to as Flicker (flicker) phenomenon.There are one optimal reference electricity by each TFT-LCD
Vcom is pressed, in optimal reference operating at voltages, the flicker value of TFT-LCD is minimum, and working condition is best.In order to reduce mobile phone,
The power consumption of the liquid crystal display panel of the electronic devices such as TV needs to increase dynamic frame frequency function, dynamic frame frequency in electronic device
Whether function, i.e. frame data of the basis from system are identical as driving circuit current frame data and different frame frequencies is used to carry out frames
The transmission of data.For example, when the frame frequency that 40Hz or 60Hz is respectively adopted carries out data transmission, due to TFT electric leakage degree not
Together, the optimal reference voltage Vcom under this 2 frame frequencies and unequal.In the case where dynamic frame frequency function is opened, work as frame frequency
When becoming 40Hz from 60Hz, since the optimal reference voltage of display screen is not necessarily identical under different frame frequencies, i.e., compared to
The frame frequency of 60Hz carries out data transmission, and the optimal reference voltage when being carried out data transmission with the frame frequency of 40Hz is deviated；
If reference voltage corresponding to the frame frequency still with 40Hz is applied on display panel, can cause under same picture
Flicker values are different, and flicker values when showing as carrying out data transmission with the frame frequency of 40Hz are bigger than normal, captured by human eye
The phenomenon that film flicker, influences picture display effect and picture display quality.
Referring to Fig. 2, Fig. 2 is a kind of flow signal improving the method that display screen is shown provided in an embodiment of the present invention
Figure.As shown in Fig. 2, the method that the improvement display screen is shown at least may comprise steps of：
S101 obtains next frame data of next frame；
S102 judges whether the current frame data of next frame data and present frame is identical, wherein the current frame number
The first frame frequency is transmitted according to this, and the corresponding reference voltage of the present frame is the first reference voltage.
S103 judges whether the previous frame data of the current frame data and previous frame are identical.
S104, if next frame data are identical as the current frame data, and the current frame data and described upper one
Frame data differ, then transmitting next frame data to display screen with the second frame frequency is shown, and by the next frame pair
The reference voltage answered is set as the second reference voltage, wherein second frame frequency is different from first frame frequency, second reference
Voltage is different from first reference voltage.
In order to solve the problems, such as the existing film flicker in the case where dynamic frame frequency is opened, it is right that the present invention needs first to obtain next frame institute
The frame data answered, and it is compared with current frame data and current frame data is compared with previous frame data, so as to
It determines what kind of frame frequency next frame data are transmitted with, and determines the corresponding optimal reference voltage of the next frame.
In the embodiment of the present invention, the next frame refers to the picture to show on a display screen or image；It is described to work as
Previous frame refers to that the picture or image that current time is just showing on a display screen, previous frame refer to before present frame, just
The picture or image shown on a display screen.In the embodiment of the present invention, the frame data of next frame are referred to as " next frame
The frame data of present frame are referred to as " current frame data " by data ", and the frame data of previous frame are referred to as " previous frame data ".
In addition, each frame data may include gray scale (such as drain voltage data of each TFT), saturation degree, brightness and histogram etc.,
It is identical by comparing whether these parameters of each frame correspond to, to determine whether frame data are identical.Histogram can be ash
The histogram of degree, histogram of saturation degree etc., for example, the histogram of gray scale can be pixel number, the gray scale by gray scale for 0
The statistical chart that the pixel number that pixel number ... gray scale for 2 is 255 is formed.The value of gray value is 0-255.
For example, next frame data are identical as the current frame data, can refer to m rows × n row of the next frame
The matrix raw column data that the drain voltage data of a TFT are constituted, the drain voltage number with m rows × n row TFT of the present frame
It is identical according to the matrix raw column data of composition.Similarly, as long as the drain voltage number of the m rows of the next frame × n row TFT
According to a data in matrix, with corresponding that in the drain voltage data matrix of m rows × n row TFT of present frame
The drain voltage data of TFT differ, you can think that next frame data are differed with the current frame data.
In the embodiment of the present invention, the current frame data, previous frame data etc. can be stored in source driving chip.Separately
Outside, previous frame, present frame, next frame are dynamic changes, and after next frame data are transmitted to display screen, the next frame is
As present frame, i.e., " frame data of the frame data as present frame for storing the next frame ".The present frame becomes previous frame,
The previous frame becomes upper frame (previous frame of previous frame), and so on.
In the embodiment of the present invention, current frame data described in S103 is still to be transmitted with the first frame frequency, the present frame
Corresponding reference voltage is the first reference voltage.The execution sequence of step S102 and S103 do not limit, and can first carry out step
Rapid S102 can also be to first carry out S103, can also be to be performed simultaneously S102 and S103.Preferably, step S103 is first carried out, then
Execute step S102.In one embodiment of the present invention, when judging whether next frame data and current frame data are identical
When, when transmitting the current frame data, judge whether the current frame data is identical as previous frame data, therefore
The judging result can be called when transmitting next frame data, and may not necessarily carry out repeating judgement again.For example,
When to transmit 3 frame, the 2nd frame is present frame, and the 1st frame is the previous frame having been transmitted through, and compares the frame of the 3rd frame and the 2nd frame
Whether data are identical, and compare whether the 2nd frame is identical as the frame data of the 1st frame, to transmit the frame of the 3rd frame with a certain frame frequency
Data, and whether identical judging result stores with the frame data of the 2nd frame by the 3rd frame.And when to transmit 4 frame, the 3rd
Frame becomes present frame, and the 2nd frame becomes previous frame, and whether need to compare the 4th frame at this time identical as the frame data of the 3rd frame, and
The frame data of 3rd frame and the 2nd frame it is whether identical it is known that, can directly invoke.
Since under different frame frequencies, the optimal reference voltage of display screen is not necessarily identical, when frame frequency changes, if
Changeless reference voltage still is loaded to display screen, then display screen will appear flicker.Based on this, in the embodiment of the present invention,
After the next frame data for obtaining next frame, if next frame data are identical as the current frame data of present frame, and present frame
Data are differed with previous frame data, then transmit next frame data with the second frame frequency different from first frame frequency
(second frame frequency is preferably less than first frame frequency), and adjust the corresponding reference voltage of the next frame, with obtain with
Optimal reference voltage (the second reference voltage) corresponding to second frame frequency, improves the flicker problem of display screen.Wherein, described second
Reference voltage is different from first reference voltage.For example, if the frame data of previous frame are that (following citing is with frame number by B
Illustrate according to for gray scale), the frame data of present frame are C, and wherein present frame is transmitted with the first frame frequency 60Hz, and present frame is corresponding
Reference voltage is Vcom1；If the frame data of next frame are still C, which is transmitted with the second frame frequency (such as 40Hz)
According to the next frame being shown on display screen, and the corresponding reference voltage of next frame is changed to one second be set as different from Vcom1
Reference voltage Vcom2, second reference voltage Vcom2 are the reference voltage of display screen.
Optionally, " described to be shown with the second frame frequency transmission next frame data to display screen in the step S104
Show, and the corresponding reference voltage of the next frame be set as the second reference voltage " it may include steps of：
11) next frame data are transmitted with the second frame frequency, and first reference voltage is increased or is reduced default inclined
Shifting value is as the second reference voltage, wherein second frame frequency is less than first frame frequency；
12) the corresponding reference voltage of the next frame is set as second reference voltage.
In the embodiment of the present invention, judging that next frame data are identical as the current frame data of present frame, and described is working as
When preceding frame data are differed with previous frame data, it is changed to the second frame frequency (being preferably less than the first frame frequency) transmission next frame
Data.Since under different frame frequencies, the optimal reference voltage of display screen usually differs, the embodiment of the present invention is also worked as by described in
As the second reference voltage Vcom2, i.e., the corresponding first reference voltage Vcom1 of previous frame increases or reduces preset offset value Δ Vcom
Vcom2=Vcom1 ± Δ Vcom, and Vcom2 is arranged to the corresponding reference voltage of the next frame.When frame frequency is by the first frame frequency
When (such as 60Hz) becomes the second frame frequency (such as 40Hz), and optimal reference variation △ Vcom, if offset is increases △
Vcom, then optimal reference voltage strain at this time is Vcom+ △ Vcom；If offset is reduction Vcom, optimal reference at this time
Voltage strain is Vcom- △ Vcom.Wherein, preset offset value Δ Vcom can be configured as needed, under making
For one frame under the reference voltage of Vcom1 ± Δs Vcom, the flicker value of picture is minimum.In general, the second frame frequency and described first
The difference of frame frequency is smaller, and set preset offset value Δ Vcom is also just smaller.The second reference voltage Vcom2 closer to
Optimal reference voltage corresponding to second frame frequency.
Optionally, " described to be shown with the second frame frequency transmission next frame data to display screen in the step S104
Show, and the corresponding reference voltage of the next frame be set as the second reference voltage " it may include steps of：
21) next frame data are transmitted with the second frame frequency, wherein second frame frequency is less than first frame frequency；
22) according to the correspondence of frame frequency and reference voltage, the corresponding reference voltage of second frame frequency is obtained, it will be described
The corresponding reference voltage of second frame frequency is as the second reference voltage；
23) the corresponding reference voltage of the next frame is set as second reference voltage.

Shown in lower.
Table 1
| Frame frequency (Hz) | Reference voltage (volt) |
| 60 | 0.8 |
| 50 | 0.5 |
| 40 | 0.3 |
As shown in table 1, different frame frequencies corresponds to different reference voltages, for example, and the frame data of previous frame are B, when
The frame data of previous frame are C, the frame data of next frame are still C, if previous frame is transmitted with 60Hz, the corresponding reference voltage of previous frame
0.8V, if present frame is still transmitted with 60Hz, present frame corresponding reference voltage still 0.8V, then next frame transmitted with 40Hz,
The corresponding reference voltage of next frame is 0.3V.
In the embodiment of the present invention, judging that next frame data are identical as the current frame data of present frame, and described is working as
When preceding frame data are differed with previous frame data, it is changed to the second frame frequency (being preferably less than the first frame frequency) transmission next frame
Data, according to the correspondence of frame frequency and reference voltage, it is assumed that the corresponding reference voltage of the first frame frequency is Vcom1, the second frame frequency
Corresponding reference voltage is Vcom2, then the corresponding reference voltage of the next frame is changed to the corresponding reference voltage of the second frame frequency
Vcom2, to improve the flicker problem of display screen.
