As shown in fig. 3, which is a schematic diagram of a cross cursor, cross lines of the cross cursor may be connected, an intersection point of the cross lines may be determined, and the intersection point may be determined as a center point of the cross cursor. Specifically, as shown in fig. 2, a coordinate point B (200, 290) is found on a transverse reference line and a coordinate point a (200, 300) corresponding to the coordinate point B is found on a first curve according to the method described in the previous step, error data is calculated according to the coordinate point a and the coordinate point B, a center point of a cross cursor is moved to a defect point according to the error data, namely, the center point of the cross cursor is moved to the coordinate point a, the cross cursor lights the coordinate point a, and the coordinate point a is used as a positioning position of a pixel point of an image to be displayed on a point screen of the current panel.

Respectively calculating the coordinate average value of at least two specific points of each area, and determining the flatness of the current panel according to the coordinate average value of each area;
and if the flatness of the current panel is not within a predetermined flatness threshold value, determining that the current panel has defects.
4. The method as recited in claim 1, further comprising:
And displaying the image to be displayed based on the positioning position of the point screen.
5. A spot screen position locating device, comprising:
A curve and reference line determining module, configured to determine a first curve, a lateral reference line, or a longitudinal reference line of a current panel when it is determined that the current panel has a defect, where the first curve is a curve formed by a defect point of the current panel, and the lateral reference line and the longitudinal reference line are curves formed by a reference point of the current panel; a second coordinate data determining module, configured to obtain first coordinate data of any reference point on the transverse reference line or the longitudinal reference line, and determine second coordinate data of a defect point on the first curve based on the first coordinate data;
the position positioning module is used for calculating error data according to the first coordinate data and the second coordinate data, moving the center point of the cross cursor to the defect point according to the error data, and taking the second coordinate data of the defect point as the position of the pixel point of the image to be displayed on the point screen of the current panel;
The curve and reference line determining module is further used for conducting grid division on the current panel according to a preset grid size;
Determining a standard center point according to first positioning points and second positioning points of the same grid row or the same grid column on two parallel sides of the current panel;
connecting the first positioning point, the second positioning point and the standard center point to obtain the transverse or longitudinal reference line;
The second coordinate data determining module is further configured to determine a defect point coordinate matrix of the first curve, a reference point coordinate matrix of the transverse reference line or the longitudinal reference line;
Determining a first abscissa and a first ordinate in the first coordinate data according to the first coordinate data of any reference point;
And searching the coordinate data which are the same as the first abscissa or the first ordinate from the defect point coordinate matrix, and taking the coordinate data which are the same as the first abscissa or the first ordinate as second coordinate data of the defect point on the first curve.
6. A spot-screen position locating apparatus comprising a memory, a processor and a computer program stored on the memory and executable on the processor, wherein the processor implements the spot-screen position locating method according to any one of claims 1-4 when executing the computer program.
7. A storage medium containing computer executable instructions which when executed by a computer processor implement the dot screen position locating method of any of claims 1-4.
