Polarizer attachment detection method and device, and display device

A polarizer attachment detection device, comprising:

• a memory, a processor, and a computer program stored in the memory and executable by the processor, the computer program when being executed by the processor performing the following operations:
• controlling an image collection device to collect image data displayed by the display device after attachment of a polarizer to a surface of the glass substrate in a current detection mode;
• comparing the image data in the current detection mode to prestored standard image data;
• in response to the image data in the current detection mode failing to match the prestored standard image data, switching to a next detection mode, controlling the image collection device to collect new image data after the attachment of the polarizer in the next detection mode, wherein the prestored standard image data is image data that the attachment of the polarizer is correct;
• comparing the new image data to the prestored standard image data;
• in response to the new image data matching the prestored standard image data, outputting result information that the attachment is correct;
• and
• in response to the new image data failing to match the prestored standard image data, outputting result information that the attachment is incorrect;
• wherein a parameter of a polarizer of a same manufacturer exceeds a certain range, a different detection mode is set for the polarizer of the same manufacturer.

A display device, comprising a display panel and a polarizer attachment detection device, the polarizer attachment detection device comprising:

• a memory, a processor, and a computer program stored in the memory and executable by the processor, the computer program when being executed by the processor performing the following operations:
• controlling an image collection device to collect image data displayed by the display device after attachment of a polarizer to a surface of the glass substrate in a current detection mode;
• comparing the image data in the current detection mode to prestored standard image data;
• in response to the image data in the current detection mode failing to match the prestored standard image data, switching to a next detection mode, controlling the image collection device to collect new image data after the attachment of the polarizer in the next detection mode, wherein the prestored standard image data is image data that the attachment of the polarizer is correct;
• comparing the new image data to the prestored standard image data;
• in response to the new image data matching the prestored standard image data, outputting result information that the attachment is correct;
• and
• in response to the new image data failing to match the prestored standard image data, outputting result information that the attachment is incorrect;
• wherein a parameter of a polarizer of a same manufacturer exceeds a certain range, a different detection mode is set for the polarizer of the same manufacturer.
