Referring to Fig. 2, propose to show in the present embodiment the invention shows the gamma value adjusting method first embodiment of panel
The gamma value adjusting method of panel the following steps are included:
Step S10, control carry out the picture that gamma value display panel adjusted exports preset each grayscale;
The gamma value of display panel adjusts and the confirmation of adjusted value can also be in different systems in the same processing procedure
Journey can mark whether gamma value is adjusted by identifying in same processing procedure, be identified as 1 it is believed that adjusted, be 0
Illustrate not adjust.
Preset grayscale can white and the corresponding grayscale of black, the picture of output is the pure color picture of each grayscale.
The grayscale picture can be transmitted to panel by the controller connecting with panel, and panel is shown after receiving the picture
Show, the picture of the controller can be obtained by server, and controller can first obtain panel type, and server is according to panel type to control
Device processed issues corresponding picture.
Step S20 acquires the corresponding brightness of picture of each grayscale, and according to the brightness calculation gamma value;
Whether step S30, the gamma value that contrast conting obtains determine gamma value adjustment with default gamma value range
Correctly, wherein when the gamma value being calculated is within the scope of the default gamma value, determining the adjustment of the gamma value just
Really.
Brightness value can be obtained by the color-values (such as rgb value) of each pixel in display panel, be shown before ability sovolin
The brightness of current display picture can be obtained according to the color-values of each pixel for the color-values of each pixel in picture.Gamma
Value can be obtained according to brightness and gamma electric voltage, can be directly according to the obtained brightness value of detection and gamma when detecting brightness
Voltage calculates gamma value, and the brightness of each grayscale can calculate separately.
Default gamma value range is 2.0-2.4, and after step S30, the judgement of exportable gamma value is as a result, being successfully
Directly output gamma curve adjusts successful prompt information, is being unsuccessfully, and directly output adjusts the prompt information to fail.Alternatively,
It is understood that returning to the execution control when determining gamma value adjustment failure and carrying out gamma value display surface adjusted
Plate exports the step of picture of preset each grayscale, to re-start adjusting to gamma value, is greater than preset value adjusting number
When, the prompt information of output adjustment failure.
Originally it implements in disclosed technical solution, after carrying out gamma value adjustment, it is adjusted aobvious that control carries out gamma value
The corresponding brightness of picture shown that panel exports the picture of preset each grayscale, and acquire each grayscale, according to the brightness of acquisition
It calculates gamma value and is determining the adjustment of the gamma value just when the gamma value being calculated is within the scope of the default gamma value
Really, the program is again according to calculating gamma value to determine the accuracy of gamma adjustment, rather than directly determines final gamma value
Whether in preset range so that gamma value adjusted it is more accurate
Further, it is proposed based on first embodiment the invention shows the gamma value adjusting method second embodiment of panel,
In the present embodiment, before the step S10 further include:
Step S40 controls the display panel the picture for exporting preset each grayscale;
Step S50 acquires the corresponding brightness of picture of each grayscale, corresponding according to each grayscale of the brightness calculation of acquisition
Gamma value;
Step S60 generates the gamma curve of the display panel according to the gamma value being calculated.
Controller can successively transmit the pictures of 255 grayscale to display screen, excessive to keep away face test point, can be every default ash
Order (such as 4 grayscale) is used as a test point, and exports the picture of the corresponding grayscale in the monitoring point, and display panel is receiving
The picture received is shown after picture, and acquiring the brightness of picture, which is detected by luminance meter or inspection software
It arrives, in per cent by grayscale then asks brightness transition with the method for taking logarithm for transmitance after detecting brightness
There emerged a a little corresponding gamma value, if the gamma value being calculated after obtaining gamma value not within the scope of 2.0-2.4, can be again
It is corrected.
The coordinate system of gamma curve is that transmitance coordinate corresponding with grayscale is formed, then default after gamma is calculated
Coordinate system in mark the gamma value being calculated, and connect each gamma value and form gamma curve.Due to detection
Picture it is limited, the curve formed after connecting gamma value may be not smooth enough, it may appear that inflection point, at this time can be to the part of inflection point
It is smoothed, the mode of smoothing processing may include increasing the mode of test point, is calculated according to increased test point
Gamma value reappears the connection for carrying out curve.
After carrying out gamma adjustment, there may be part gamma value not within a preset range as within the scope of 2.0-2.4, then
After generating gamma curve, the gamma curve is compared with standard gamma curve;In the gamma curve and standard gal
There are when error between horse curve, the gamma electric voltage output in gamma chip is adjusted.
After generating gamma curve, standard transmitance can be calculated by standard gray scale and standard gamma value, marked
Transmitance under each grayscale is compared with standard transmitance, can obtain the deviant of transmitance, root by quasi- gamma curve
Voltage change can be obtained according to the deviant of transmitance, transmitance is excessively high, needs to reduce gamma electric voltage, and transmitance is too low then
Gamma electric voltage value can be increased.Adjustment gamma electric voltage can be divided into two ways, symmetrical voltage adjustment mode and the adjustment of asymmetric voltage
Mode obtains the voltage that can be set by the register adjusted in gamma chip after final gamma electric voltage, realizes gamma electric voltage
Adjustment.
Define the generating mode of gamma curve in technical solution disclosed in the present embodiment, directly according to the brightness of detection with
And corresponding grayscale generates gamma curve.
Further, referring to Fig. 4, propose that the invention shows the gamma value adjusting sides of panel based on first or second embodiments
Method 3rd embodiment, in the present embodiment, before the step S10 further include:
Step S70 lights the back light of display panel;
Step S80 carries out picture detection to the display panel after the brightness stability of display panel;
After the completion of picture detection, the step S10 is executed, that is, controls the display panel the figure for exporting preset each grayscale
Piece.
Picture detection may include the detection of flashing, when testing result does not meet standard value, join to the display of display panel
Number is adjusted, and then re-starts detection, when testing result complies with standard value, executes step S10.
Embodiment defines panels to carry out other adjustment processes before gamma curve adjusting, so that display panel is aobvious
Show more stable.
In addition, the present invention also proposes that a kind of gamma value adjusting device of display panel, the gamma value of display panel adjust dress
Set includes: memory, processor and the gal for being stored in the display panel that can be run on the memory and on the processor
Horse value adjusts program, and the gamma value of display panel adjusts when program is executed by processor and realizes electricity consumption display panel as described above
Gamma value adjusting method the step of.
In addition, the present invention also proposes a kind of computer readable storage medium, stored on the computer readable storage medium
There is the gamma value of display panel to adjust program, the gamma value of shown panel is adjusted when program is executed by processor and realized as more than
The step of gamma value adjusting method of the display panel.
In addition, the present invention also proposes a kind of gamma value adjusting device of display panel, which is characterized in that the display panel
