DISPLAY DEVICE - A simplified explanation of the abstract

This abstract first appeared for US patent application 20240119877 titled 'DISPLAY DEVICE

Simplified Explanation

The patent application describes a display device that includes a display panel, an input sensor, a display controller, and a sensor controller. The sensor controller provides a transmission signal with multiple sampling periods to the input sensor, and the display controller communicates frequency information of a display frame period to the sensor controller. The sensor controller adjusts the number of sampling periods based on the frequency information.

• Display device with input sensor and sensor controller:

 - The device includes a display panel and an input sensor for sensing input during a sensing frame period.
 - A sensor controller provides a transmission signal with multiple sampling periods to the input sensor.
 - The sensor controller adjusts the number of sampling periods based on frequency information received from the display controller.

• Display controller with frequency information:

 - The display controller receives vertical and horizontal synchronization signals to control driving of the display panel.
 - It provides frequency information of the display frame period to the sensor controller.
 - The frequency information is used by the sensor controller to adjust the number of sampling periods during the sensing frame period.
