Specific embodiment
The present invention is described in further detail with reference to the accompanying drawings and examples.It is understood that this place is retouched
The specific embodiment stated is used only for explaining the present invention rather than limiting the invention.It also should be noted that in order to just
Only the parts related to the present invention are shown in description, attached drawing rather than entire infrastructure.
Fig. 1 is a kind of flow diagram of the image processing method of the display panel provided in the embodiment of the present invention, the party
Method is suitable for eliminating influence of the moire fringes to electronic image spatial frequency data, to obtain the real image data of electronic image
The case where.This method can be executed by a kind of image processing system of display panel.The image processing system of the display panel
It can be realized by the mode of software and/or hardware.
With reference to Fig. 1, this method specifically comprises the following steps:
Step 110 is shown according to repeatedly adjustment optical detection apparatus relative to multiple groups collected behind the position of display panel
