  • Patent number: 9612682
    Abstract: A touch panel includes electrode lines and a detecting circuit. The detecting circuit includes driving units and detecting units. The driving units are configured to sequentially output driving signals to the electrodes lines according to a first clock signal, so as to change the voltage levels of the electrode lines. Two ends of each of the electrode lines are respectively coupled to a driving unit and a corresponding detecting unit. The detecting units are configured to sequentially scan the voltage levels of the electrode lines according to a second clock signal and to output scan signals, in which the first clock signal and the second clock signal have different frequencies. The detecting circuit generates a detecting signal according to the scan signals.

  • Publication number: 20150002555
    Abstract: A display apparatus includes a display module and a backlight module. The display module includes a substrate and a display panel. The substrate includes an image region and a control region, and the control region is located at an edge of the substrate. The display panel has a first surface and a second surface opposite to the first surface. The backlight module includes a light guide plate, a circuit board, a first light source unit and a second light source unit. The circuit board has a first portion disposed on the first surface and a second portion disposed on the second surface. The first light source unit is disposed on the first portion and provides lights to an incident surface of the light guide plate. The second light source unit is disposed on the second portion and provides lights to the control region.

  • Publication number: 20060244739
    Abstract: A display driver IC and a driving method. The display driver IC is for receiving a system signal to drive a display panel or transmit data to a device. The display driver IC includes an input/output interface circuit, an index register, a control register and a device interface circuit. The input/output interface circuit receives the system signal and then outputs a first address signal and a first data signal accordingly. The index register stores and outputs the first address signal. The control register stores the first data signal and outputs the first data signal according to the first address signal output from the index register. The device interface circuit generates a second data signal according to the first data signal and outputs the second data signal to the device.
