Method and system for detecting defective pixels and screen imperfections of a mobile device

1. A method for detecting defective pixels and screen imperfections, comprising the steps of:

positioning a mobile device having a display screen in a testing chamber;

capturing an image of the display screen using a camera directed to the display screen, wherein the image has a plurality of image pixels and is a photographic representation of rows and columns of a plurality of display pixels of the display screen, each image pixel having Red, Green, and Blue values (RGB values) varying from 0-255;

performing a pixel detection analysis of the image;

determining an image pixel of the plurality of image pixels is a questionable pixel if at least two of the R, G, and B values of the image pixel are greater than 30;

comparing the questionable pixel against 8 surrounding pixels:

categorizing the questionable pixel as a drastic change pixel when more than 4 of the 8 surrounding pixels have a significant variance from the questionable pixel, the categorizing step including calculating a difference for each of the R, G, and B values between the questionable pixel and each of the surrounding pixels, a surrounding pixel of the surrounding pixels having the significant variance from the questionable pixel if the difference of one of the R, G, and B values is at least 25 and the difference of at least one of the other two R, G, and B values is greater than 3.

2. The method according to claim 1 , further comprising the step:

loading a defective pixel mobile application to the mobile device.

3. The method according to claim 2 , wherein the defective pixel mobile application is loaded through a connector or communication protocol.

4. The method according to claim 2 , wherein the defective pixel mobile application sets the display screen black with a backlight turned ON to a maximum setting.

5. The method according to claim 2 , wherein the defective pixel mobile application is an application that functions on a mobile device operating system.

6. The method according to claim 1 , wherein a pure white pixel color has values of R=255, G=255 and B=255 and a pure black pixel color has values of R=0, G=0 and B=0.

7. The method according to claim 1 , further comprising the step of: identifying a defective display pixel when there are more than 5 drastic change pixels in a 15×15 image pixel range.
