Display system, driver integrated circuit applied to the display system, and associated method

A display system includes an image sensor, a display panel, and a driver integrated circuit (IC). The image sensor is arranged to capture a gaze direction of an observer. The display panel includes a plurality of pixels arranged in a pixel array, and a first conductive lines coupled to a first transistor in a gaze zone in the pixel array. The first conductive line is arranged to carry signal to the first transistor. The driver IC is coupled to the image sensor and the display panel, and includes a selecting circuit. The selecting circuit is arranged to selectively transmit a first signal to the first transistor in the gaze zone via the first conductive line according to the gaze direction.
