As shown in fig. 1, fig. 1 is a schematic flow chart of a defect repairing method for a liquid crystal display panel according to an embodiment of the present invention, which is applied to the field of display technology, and the specific flow of the defect repairing method includes steps S101 to S107:
s101, a step: judging whether the liquid crystal display panel to be detected is the first sheet;

If the parameter of the identification point to be detected is consistent with the preset parameter, the preset position of the liquid crystal display panel to be detected is consistent with the preset position of the liquid crystal display panel, the geometric correction step is not needed, and the next image shooting step can be directly carried out. Then, a detection image of the liquid crystal display panel to be detected is obtained through the image shooting step, and the data processing step is carried out on the detection image. And then, according to the data processing step, calculating to obtain compensation data and forming a compensation table, burning the data of the compensation table into a flash memory of the liquid crystal display panel to be tested, and restarting the time schedule controller. After the liquid crystal display panel is subsequently started, compensation can be carried out according to the compensation table, so that the problem of display defects of the liquid crystal display panel is solved, and the display effect is improved.

In the production process, the repair time affects the manufacturing cost of the product, for example, the DeMura repair time of the conventional 4K2K display panel is about 35 seconds, the repair time is long, and the production cost and the production efficiency are affected.
As shown in fig. 2, a defect repairing method in the prior art includes:

and judging whether the first coordinate value, the second coordinate value and the first included angle are respectively consistent with the first preset coordinate value, the second preset coordinate value and the preset included angle.
Wherein the predetermined included angle is in a range of 0-90 °.
Specifically, the preset included angle ranges from 0 to 90 °. Preferably, the predetermined angle is 0 °, but it is considered that the mounting error may fluctuate within a small range. In addition, the preset included angle may be 90 ° in consideration of other cases.
The liquid crystal display panel of the first piece is provided with a preset identification point, the first preset coordinate value and the second preset coordinate value are respectively a horizontal coordinate value and a vertical coordinate value of the preset identification point, and the preset included angle is a connecting line formed by the preset identification point and a coordinate origin and an included angle between the preset identification point and the direction or the vertical direction.
Wherein, after judging whether the liquid crystal display panel is the first one, still include:
if so, skipping the step of judging whether the parameters of the identification points to be detected of the liquid crystal display panel are consistent with the preset parameters, and carrying out the geometric correction step.
Specifically, as shown in fig. 3, a preprocessed image of the prior art is provided, where the preprocessed image of the prior art has a black background region and pixels distributed in an array. Fig. 4 shows a preprocessed image according to an embodiment of the invention. As shown in fig. 5, which is a partially enlarged view of the box area in fig. 4. As can be seen from fig. 4 and 5, the preprocessed image according to the embodiment of the present invention has a black background region, pixels distributed in a matrix, an outer frame region located outside the pixels, and an identifier point located at the top left corner of the preprocessed image according to the embodiment of the present invention, where the identifier point has an X coordinate value, a Y coordinate value, and an included angle θ. The liquid crystal display panel of the first piece is provided with a preset mark point, the preset mark point is provided with a first preset coordinate value, a second preset coordinate value and a preset included angle, the first preset coordinate value and the second preset coordinate value are values of the preset mark point on an X coordinate axis and a Y coordinate axis, and the preset included angle is a connecting line formed by the preset mark point and an original point of a coordinate and an included angle between the preset mark point and the original point of the coordinate and the horizontal direction or the vertical direction. The liquid crystal display panel to be detected, which is not the first liquid crystal display panel to be detected, is provided with a mark point to be detected, the mark point to be detected is provided with a first preset coordinate value, a second preset coordinate value and a preset included angle, the first preset coordinate value and the second preset coordinate value are the value of the mark point to be detected on an X coordinate axis and the value of the mark point to be detected on a Y coordinate axis, and the first included angle is the connecting line formed by the mark point to be detected and the origin of coordinates and the included angle between the connecting line and the horizontal direction or the vertical direction.
Wherein, the identification point parameter that awaits measuring of the liquid crystal display panel that awaits measuring includes first coordinate value, second coordinate value and first contained angle at least, judges whether the identification point parameter that awaits measuring of liquid crystal display panel is unanimous with the preset parameter, specifically includes: and judging whether the first coordinate value, the second coordinate value and the first included angle are respectively consistent with the first preset coordinate value, the second preset coordinate value and the preset included angle. When the first coordinate value, the second coordinate value and the first included angle are consistent with the first preset coordinate value, the second preset coordinate value and the preset included angle respectively, the fact that the positions of the liquid crystal display panel to be detected of the non-first piece and the liquid crystal display panel of the first piece are consistent indicates that the geometric correction step can be skipped, so that the overall time of the repair process is reduced, the production efficiency is improved, and the production cost is reduced.
It can be understood that, in general, the step of collecting and judging whether the parameter of the identification point to be detected of the liquid crystal display panel to be detected is consistent with the preset parameter only needs 0.2 second, the time for performing the geometric correction step needs 5 seconds, and the geometric correction step is skipped, so that the overall time for repairing can be effectively reduced, the production efficiency is improved, and the production cost is reduced. Compared with the preprocessed image in the prior art, the preprocessed image in the embodiment of the invention is provided with the mark point to be detected and the white outline, and the coordinates of the starting point in X and Y and the angle of the mark point to be detected can be obtained by adding the white mark point to be detected; the image is cropped by adding a white outline for locating the ROI area.
In addition, it should be noted that, by the method of the embodiment of the present invention, the display unevenness defect of the liquid crystal display panel can be repaired, and the display unevenness defect may be a luminance unevenness defect. In addition, the display unevenness defect may also be a chromaticity unevenness defect, and in some cases, the chromaticity unevenness defect of the liquid crystal display panel may also be repaired by the method of the embodiment of the present invention.
Wherein, after judging whether the to-be-detected identification point parameter of the liquid crystal display panel is consistent with the preset parameter, the method further comprises the following steps:
if not, a geometric correction step is carried out.
Specifically, when the parameter of the identification point to be detected of the liquid crystal display panel is judged to be inconsistent with the preset parameter, the correction coefficient can be calculated through the geometric correction step and the pre-processing image of the liquid crystal display panel to be detected, so that the subsequent image shooting step is facilitated. The geometric correction may be to calculate a correspondence between image pixels and panel pixels to generate a correction coefficient.
Wherein, carry on and shoot the step of the picture and carry on the data processing step, include specifically:
collecting images of all areas of a liquid crystal display panel to be detected and generating a detection image;
and acquiring a detection image in an overexposure state, obtaining the coordinate value and the gray-scale value of each line of pixels, and determining a background area and a defective pixel point with uneven brightness according to the gray-scale value.
Wherein, gather the detection image with overexposure state, specifically include:
and removing the polarization effect on the photographing lens to enable the photographing lens to be in an overexposure state, so as to photograph, acquire and detect images.
