Abstract: A beam transmitter and an optical touch display system are disclosed. The beam transmitter includes a first light source, a second light source, a power supply component, a touch sensor, and a control module. The beam transmitter includes a first projection state and a second projection state. The control module is respectively connected to the power supply component, the touch sensor, the first light source, and the second light source, and the control module controls the beam transmitter to switch between the first projection state and the second projection state according to a state of the touch sensor.

Abstract: A touch structure and a touch display panel are disclosed. The touch structure includes a plurality of touch units, a plurality of touch row selection lines, and a plurality of touch column readout lines. One of the touch column readout lines is configured using one column of the touch units, and required touch signals can be read out using only N touch column readout lines. In addition, one of the touch row selection lines is electrically connected to one row of the touch units. Therefore, the required touch signals may be read row by row, thereby avoiding the ghosting.

Abstract: An embodiment of the present invention provides a touch display panel and a touch display device including an underlay substrate and touch electrodes. The touch electrodes include a plurality of pattern electrodes. Adjacent ones of the pattern electrodes along are arranged in a staggered arrangement a first direction. The pattern electrode has a first width along the first direction and has a second width along a second direction. The second width is greater than the first width. Changing an arrangement of the pattern electrodes reduces touch lead lines in the display panel, improves a touch precision of the display panel, and lowers a manufacturing cost.
