DISPLAY DEVICE INCLUDING A TEST PIXEL - A simplified explanation of the abstract
This abstract first appeared for US patent application 18230539 titled 'DISPLAY DEVICE INCLUDING A TEST PIXEL
Simplified Explanation
The abstract of the patent application describes a display device that includes a display panel with a normal pixel in a display region and a test pixel in a peripheral region. A sensing line is coupled to the test pixel, and a sensing circuit is configured to sense a mobility characteristic of the test pixel by measuring a current at a source node of the test pixel through the sensing line. The source node of the test pixel is electrically separated from the sensing line in a data writing period of a frame period, and is electrically coupled to the sensing line in an emission period of the frame period.
- Display device with a test pixel in a peripheral region for sensing mobility characteristics
- Sensing circuit measures current at source node of test pixel through sensing line
