  • Optical touch display apparatus
    Patent number: 9377886
    Abstract: An optical touch display apparatus including a backlight module, a display panel, and at least an optical detector is provided. The backlight module is capable of providing a visible beam and an invisible beam. The display panel is disposed at one side of the backlight module. A sensing space is located in front of the display panel, and the display panel is located between the backlight module and the sensing space. The visible beam and the invisible beam are capable of passing through the display panel and then being transmitted to the sensing space. The optical detector is disposed outside the display panel for sensing the invisible beam from the sensing space.

  • Optical touch apparatus and drive method to control an average brightness of LEDs
    Patent number: 8830210
    Abstract: An optical touch apparatus including a first light emitting device, a second light emitting device, a third light emitting device, a fourth light emitting device, a first image detector, a second image detector, and a control unit is provided. The control unit controls the average brightness of the third light emitting device less than each of the average brightness of the second light emitting device and the fourth light emitting device when the control unit controls the first image detector to detect an image. The control unit controls the average brightness of the second light emitting device less than each of the average brightness of the first light emitting device and the third light emitting device when the control unit controls the second image detector to detect an image. A driving method is also provided.
