Abstract: A touch screen panel includes a unit pixel and a light sensing part. The unit pixel is connected to an N-th gate line and an M-th data line. The light sensing part is adjacent to the unit pixel. The light sensing part includes a first sensing switching element and a second sensing switching element. The first sensing switching element includes a gate electrode connected to the N-th gate line, a drain electrode connected to a P-th read out line and a source electrode connected to a first node. The second sensing switching element includes a gate electrode to which a first voltage is applied, a drain electrode connected to the first node and a source electrode connected to an X-th gate line. N, M, P and X are positive integers. Thus, an aperture ratio of the touch screen panel can be improved.

Abstract translation: 触摸屏面板包括单位像素和感光部分。 单位像素连接到第N条栅极线和第M条数据线。 光感测部分与单位像素相邻。 光感测部分包括第一感测开关元件和第二感测开关元件。 第一感测开关元件包括连接到第N栅极线的栅电极，连接到第P读出线的漏电极和连接到第一节点的源电极。 第二感测开关元件包括施加第一电压的栅电极，连接到第一节点的漏电极和连接到第X栅极线的源电极。 N，M，P和X是正整数。 因此，可以提高触摸屏面板的开口率。
