TOUCH SENSING SYSTEM AND DISPLAY APPARATUS

摘要

The present disclosure is related to a touch sensing system and a display apparatus including: a touch screen panel defining sensor nodes by first lines and second lines formed in crossing directions, a loop type antenna, and a touch processor that performs a first touch process by receiving a signal with respect to driving pulses applied to each of the first lines and the second lines, through the antenna, and performs a second touch process by sequentially applying the driving pulses to each of two or more selected lines among the first lines and the second lines and by receiving a signal through the antenna.

主权项

1. A touch sensing system comprising:
a touch screen panel that includes a screen, and that defines sensor nodes by first lines and second lines formed in crossing directions; an antenna formed in a peripheral area of the first lines and the second lines; and a touch processor configured to:
detect a coordinate of a point where a pen touches the screen, by sensing the sensor nodes through a sequential driving of the first lines and the second lines and a reception of a resonance signal of the pen touching the screen through the antenna, anddetect a pressure of the pen touching the screen, by sensing only a portion of the sensor nodes among the sensor nodes through a sequential driving of a main line corresponding to the detected coordinate among the first lines and the second lines and an adjacent line adjacent to the main line, and the reception of the resonance signal of the pen through the antenna.
