Correction data generation method, correction data generation system, and image quality adjustment technique using the method and system

A correction data generation system for generating correction data by capturing a display panel with a camera, the correction data being for reducing unevenness in display of the display panel by correcting a signal input to the display panel, the system comprising:

• a display control means that displays test patterns on the display panel in units of specific gradation values;
• a summed image generation means that generates a summed image for each specific gradation value by summing a plurality of captured images obtained by the camera capturing the test patterns a plurality of times for each specific gradation value;
• and
• a correction data generation means that generates the correction data for each specific gradation value based on the corresponding summed image.

An image quality adjustment method for adjusting image quality of a display panel using correction data for reducing unevenness in display of the display panel through correction of a signal input to the display panel, the method comprising:

• a capturing step of displaying test patterns on the display panel in units of specific gradation values, and capturing the test patterns with the camera a plurality of times for each specific gradation value;
• a summed image generating step of generating, for each specific gradation value, a summed image by summing a plurality of captured images of the test patterns;
• a correction data generating step of generating the correction data for each specific gradation value based on the corresponding summed image;
• and
• an input signal correcting step of correcting the signal input to the display panel based on the correction data.

A method for manufacturing a display panel with image quality adjustment functions including a display panel and an image quality adjustment means provided with a storage having stored therein correction data for reducing unevenness in display of the display panel through correction of a signal input to the display panel, the method comprising:

• a capturing step of displaying test patterns on the display panel in units of specific gradation values, and capturing the test patterns with the camera a plurality of times for each specific gradation value;
• a summed image generating step of generating, for each specific gradation value, a summed image by summing a plurality of captured images of the test patterns;
• a correction data generating step of generating the correction data for each specific gradation value based on the corresponding summed image;
• a correction data storing step of storing the correction data in the storage;
• and
• a mounting step of mounting the image quality adjustment means on the display panel so that the image quality adjustment means corrects the signal input to the display panel based on the correction data.
