the S3 further includes:
s4: capturing an image displayed after data compensation is carried out on the special-shaped screen to obtain a first image; converting the first image into a gray scale image corresponding to a plurality of gray scales to obtain a plurality of first gray scale images;
s5: acquiring the gray value of each sub-pixel point at the edge of each first gray-scale image according to the plurality of first gray-scale images; acquiring the gray value of each sub-pixel point at the edge of each preset gray-scale image according to the preset gray-scale images;
s6: calculating the number of gray values of each sub-pixel point at the edge of each first gray-scale image, wherein the difference between the gray values of the sub-pixel points corresponding to each gray scale is larger than a preset threshold value according to the gray value of each sub-pixel point at the edge of each first gray-scale image and the gray value of each sub-pixel point at the edge of each preset gray-scale image; the preset threshold value is 10;
s7: if the number is larger than the preset number threshold, repeating the steps S1-S6 until the calculated number is not larger than the preset number threshold; wherein the preset number threshold is 10% of all sub-pixel points of the contour edge; during the repeated execution of steps S1-S6, the compensation circuit performs the overlay compensation according to all the compensation data that have been received.
5. The special-shaped screen contour compensation terminal with good compensation effect and high efficiency as claimed in claim 4, wherein said S3 is specifically:
acquiring a gray value of each pixel point at the edge of each gray-scale image according to the plurality of gray-scale images;
acquiring a gray value of each pixel point at the edge of each preset gray-scale image according to the preset gray-scale images;
calculating compensation data corresponding to each pixel point under different gray scales at the edge of the image according to the gray value of each pixel point at the edge of each gray scale image and the gray value of each pixel point at the edge of each preset gray scale image;
and sending the compensation data to a compensation circuit corresponding to the special-shaped screen.
6. The special-shaped screen contour compensation terminal with good compensation effect and high efficiency as claimed in claim 5, wherein after said sending said compensation data to the compensation circuit corresponding to said special-shaped screen, further comprising:
controlling the compensation circuit to acquire input data of a display image;
and controlling the compensation circuit to calculate to obtain output data according to the input data and the received compensation data, and sending the output data to the special-shaped screen for display.
