Abstract:
1. A panel structure, comprising: a glass layer; a plurality of first indium tin oxide (ITO) strips; a plurality of third indium tin oxide strips, wherein the first indium tin oxide strips and the third indium tin oxide strips disposed on the glass layer, each of the first indium tin oxide strips and each of the third indium tin oxide strips interlaced in a first direction; a liquid crystal layer disposed on the first indium tin oxide strips and the third indium tin oxide strips; a plurality of second indium tin oxide strips; and a plurality of fourth indium tin oxide strips, wherein the second indium tin oxide strips and the fourth indium tin oxide strips disposed on the liquid crystal layer, each of the second indium tin oxide strips and each of the fourth indium tin oxide strips interlaced in a second direction, wherein the first direction is substantially vertical to the second direction, wherein the panel structure operates in a first grating mode during a first predetermined time, and the first indium tin oxide strips receive a voltage, and the second indium tin oxide strips and the fourth indium tin oxide strips grounded when the panel structure operates in the first grating mode, wherein the panel structure operates in a touch-sensing mode during a second predetermined time, and the first indium tin oxide strips sequentially receive a driving voltage, and the fourth indium tin oxide strips are operable to detect a touch event when the panel structure operates in the touch-sensing mode, wherein the first grating mode and the touch-sensing mode of the panel structure are implemented alternately, wherein the panel structure further comprises a controller, wherein the controller is operable to control the first indium tin oxide strips to receive the voltage and control the second indium tin oxide strips and the fourth indium tin oxide strips to be grounded when the panel structure operates in the first grating mode, and the controller is operable to control the first indium tin oxide strips to sequentially receive the driving voltage and control the fourth indium tin oxide strips to detect a touch event when the panel structure operates in the touch-sensing mode, and the controller is operable to control the panel structure to operate in the first grating mode and the touch-sensing mode alternately.
