Abstract
A display device having a test function includes a display panel; and a display driving device configured to store pattern data corresponding to test patterns for testing an image quality of the display panel and control data for controlling the pattern data. The display driving device sets a display order and a display time of each of the test patterns by using the control data, and performs driving such that at least two test patterns are displayed on the display panel depending on the control data.
Claims18
A display device having a test function, comprising:
- a display panel;
- and
- a display driving device for driving the display panel,
- where the display driving device comprises:
- a storage unit configured to store pattern data corresponding to test patterns for testing an image quality of the display panel and control data for controlling the pattern data;
- a data driving circuit configured to provide a source signal corresponding to the pattern data, to the display panel;
- a control circuit configured to set a display order and a display time of each of the test patterns by using the control data, and control the data driving circuit such that at least two test patterns are displayed on the display panel depending on the control data;
- and
- a pattern generation circuit configured to receive a command signal, and generate the pattern data by designating at least one among regions of the test patterns and colors, gradations and gradation stages for the regions, in correspondence to the command signal, wherein the command signal comprises commands for designating a plurality of pattern generators, regions of the test patterns and colors for the regions.
