DISPLAY DEVICE AND METHOD FOR MONITORING OPERATION OF PIXELS - A simplified explanation of the abstract
This abstract first appeared for US patent application 20240119891 titled 'DISPLAY DEVICE AND METHOD FOR MONITORING OPERATION OF PIXELS
Simplified Explanation
A display device described in the patent application includes a display panel with pixels connected to sensing lines, a sensing driver with a shared sensing channel for the sensing lines, and a controller to control the display panel and sensing driver. The controller disconnects the sensing channel from the sensing lines in a first time period, records electrical characteristics of the pixels as sensing voltages in the sensing lines, and then reads the sensing voltages in the sensing channel in a second time period.
