Abstract
A method and system for testing gradation levels of a display panel of an electronic device are provided. The method includes dividing a display area of the display panel into 2̂n blocks and assigning corresponding gradation values for each of the blocks, displaying the gradation levels of each of the blocks on the display panel, scanning each of the blocks and outputting the gradation values of each of the blocks, and determining a defectiveness of the display panel depending on the outputted gradation values and the assigned gradation values of each of the blocks.
Claims18
A computing system for testing gradation levels of a display panel of an electronic device, the system comprising:
- a define module configured for dividing a display area of the display panel into 2̂n blocks wherein n is the number of bits per pixels of the display panel, and for assigning corresponding gradation values for each of the blocks;
- a display module configured for displaying gradation levels of each of the blocks on the display panel;
- a scan module configured for scanning the blocks and for outputting the gradation values of each of the blocks;
- and
- an analysis module configured for determining a defectiveness of the display panel according to the outputted gradation values from the scan module and the assigned gradation values of each of the blocks.
A computer-implemented method for testing gradation levels of a display panel of an electronic device, the method comprising:
- dividing a display area of the display panel into 2̂n blocks wherein n is the number of bits per pixels of the display panel;
- assigning corresponding gradation values for each of the blocks;
- displaying gradation levels of each of the blocks on the display panel;
- scanning each of the blocks and outputting the gradation values of each of the blocks;
- and
- determining a defectiveness of the display panel depending on the outputted gradation values and the assigned gradation values of each of the blocks.
A computer-readable medium for testing gradation levels of a display panel of an electronic device, the computer-readable medium having stored thereon instructions that, when executed by the electronic device, cause the electronic device to:
- divide a display area of the display panel into 2̂n blocks wherein n is the number of bits per pixels of the display panel;
- assign corresponding gradation values for each of the blocks;
- display gradation levels of each of the blocks on the display panel;
- scan each of the blocks and outputting the gradation values of each of the blocks;
- and
- determine a defectiveness of the display panel depending on the outputted gradation values and the assigned gradation values of each of the blocks.
