Abstract
A method and apparatus can diagnose a cell defect of a PDP module. The method can include dividing a screen of a PDP module into a plurality of regions, displaying a pattern for diagnosing the cell defect on less than all the regions, and blocking at least one of the remaining regions. Further, determined cell defects identified in at least two of the plurality of regions have different weights when combined to determine a resulting value for comparison to a threshold for the PDP module.
Claims22
A method for diagnosing a cell defect of a Plasma Display Panel (PDP) module, comprising:
- dividing a screen of the Plasma Display Panel (PDP) module into a plurality of regions;
- and
- displaying a pattern for diagnosing the cell defect on a portion of the regions, wherein at least two of the regions respectively have a different prescribed weight for a corresponding cell defect therein, wherein the displaying comprises shifting the pattern through each of the regions to determine respective cell defects therein, wherein the shifting the pattern comprises combining the respective cell defects with the corresponding weight to determine a score for said each region.
An apparatus configured to diagnose a cell defect of a Plasma Display Panel (PDP) module, comprising:
- a scaler IC configured to receive and output a pattern for diagnosing the cell defect;
- the PDP module configured to display an output of the scaler IC;
- and
- a microcomputer configured to control the scaler IC to display the pattern in a diagnosing region of a plurality of regions in a screen of the PDP module, wherein the plurality of regions respectively use different prescribed weights for cell defects therein, wherein the microcomputer is configured to shift the pattern through each of the regions to determine respective cell defects therein and combine the respective cell defects with the corresponding weight to determine a score for said each region;
- and wherein the microcomputer is configured to combine the plurality of scores to determine a cell defect value for the PDP module.
A method, comprising:
- determining a plurality of regions in a display device;
- displaying a pattern for evaluating a characteristic of the display device in the plurality of regions, wherein the evaluating a characteristic identifies a cell defect, and wherein the displaying comprises shifting the pattern through the regions to determine respective cell defects therein, and combining the respective cell defects with different corresponding weights to determine a score for each region;
- and
- combining the plurality of scores to determine a cell defect value for the display device.
